Autores: Konopatzki,Marcia R. S.; Souza,Eduardo G.; Nóbrega,Lúcia H. P.; Uribe-Opazo,Miguel A.; Suszek,Grazieli.
In the last few years, precision agriculture has become commonly used with many crops, particularly cereals, and there is also interest in precision horticulture. Pear is a seasonal fruit and well appreciated by Brazilian people, although it is mostly imported. Brazilian farmers are nowadays trying to increase pear production. Thus, this research aimed at mapping the yield of pear trees in order to study the spatial variability of yield as well as its comparison with spatial variability of soil and plant attributes. The experimental field had 146 pear trees, variety 'Pêra d'água', distributed on a 1.24 ha. Four harvests were performed according to the fruit ripening and from each tree; only the ripe fruits were harvested. In each harvest, all the fruits...

Autores: Cunha,Fernando F. da; Souza,Ivan P. de; Campos,Washington de O.; Andrade Júnior,Valter C. de; Magalhães,Thiago A.
ABSTRACT In radish production, the choice of proper genotypes and irrigation regime is of great importance to achieve success. In light of this, the current study aimed to evaluate the agronomic performance of a few radish genotypes under different irrigation strategies. The plants were grown in the city of Unaí - MG, in Brazil, under field conditions, and during two cycles, one of 40 days (from February 28 to April 8, 2015) and other of 51 days (from May 9 to June 28, 2015). The experimental design was a randomized block design in a split-plot arrangement with four replications. The treatments consisted of four irrigation strategies (50, 75, 100, and 125% of crop evapotranspiration - ETc) applied by a dripping irrigation system, while subplots consisted...

Baby leaf lettuce production in trays with reused and solarized substrate
Provedor de dados: 75
Autores: Moraes,Lívia AS; Calori,Alex H; Factor,Thiago L; Patrício,Flávia RA; Ghini,Raquel; Abreu,Monica F; Purquerio,Luis FV.
ABSTRACT Concerning the baby leaf production in trays, substrate can be reused for a certain number of times depending on its chemical and physical characteristics, but populations of pathogens such as Pythium aphanidermatum and Rhizoctonia solani that can cause damping off of lettuce, can build up during the reuse of this substrate. Solar treatment in a solar collector can be an alternative for the disinfestation of these substrates. Thus, the objective of this research was to study the reuse of coconut fiber substrate and its solar treatment in solar collector on baby leaf lettuce production. The experimental design was randomized blocks, in a factorial scheme 4 (first-use substrate, reused once, reused twice and reused three times) x 2 (with and without...

Nonlinear regression and plot size to estimate green beans production
Provedor de dados: 75
Autores: Lucio,Alessandro DC; Nunes,Luis F; Rego,Francisco.
ABSTRACT The objectives of this work were to adjust nonlinear regression models for the green beans production and to identify the plot size which provides the best explanation and adjustment to the models. The authors used two field and two protected environment (plastic tunnel) trials in the autumn-winter and spring-summer seasons. The logistic and von Bertalanffy models were adjusted for average weight of green beans accumulated after multiple harvests and with different plot sizes. The models presented similar estimates and the same parameters estimates in all the plot sizes. The logistic model provided estimates closest to the reality, showing the best description performance for the average weight of pods during the productive cycle. In the...

Nitrogen on growth and yield of lettuce plants grown under root confinement
Provedor de dados: 75
Autores: Cardoso,Francieli L; Andriolo,Jerônimo L; Picio,Miriane Dal; Piccin,Marcieli; Souza,Jéssica M.
ABSTRACT: The objective of this research was to test the hypothesis that when lettuce plants grow under root confinement, development and yield is reduced and that such negative effects may be compensated by increasing nitrogen availability in the rooting media. The experiment was conducted between August 11st and September 23rd 2011. Lettuce transplants, cultivar Stella, bearing five leaves, were planted in pots using sand as substrate. Treatments were three root confinement levels and five N concentrations in the nutrient solution, in a 3x5 factorial randomized experimental design with four replications. Root confinements were simulated by pot sizes of 2.5 dm³ (no confinement, the control); 1.0 dm³ (moderate) and 0.4 dm³ (severe). Nitrogen concentrations...

HORTICULTURAL RESEARCH IN THE NETHERLANDS: CHANGES AND CHALLENGES FOR 2010
Provedor de dados: 31
Autores: van Oosten,   H.J.
Major shifts in world economy, society and technology will cause dramatic changes in Dutch horticulture and in the attitude of the government towards research. The horticulture industry will change from a production-driven to a customer-driven strategy while developing market-oriented product chains. More than ever, knowledge becomes a critical factor in competition. In contrast with the past, the horticulture industry will protect knowledge to increase its profitability.   The government will choose to focus on basic sciences, leaving applied research mainly to the industry.  This is a  major shift since the government used to be responsible for most research. Complete institutional research  programmes are no longer state-financed; instead, a system of...

ASSESSING KOSOVO'S HORTICULTURAL POTENTIAL – THE MARKET FOR FRUIT AND VEGETABLES ON THE BALKANS
Provedor de dados: 31
Autores: Fischer,   Christian.
Kosovo had been a net exporter – at least of some – fruit and vegetables in the former Federal Republic of Yugoslavia before the civil war. Current reconstruction efforts therefore focus on restoring the past horticultural potential of the now independent province. This paper analyses the competitiveness of the Kosovar fruit and vegetable sector. By calculating average net trade flows during 1996-2000 for more than 20 individual fruit and vegetables and seven aggregates, demand potentials for the Balkan regional market are identified for potatoes, lettuce, garlic, dried beans and pears. In addition, average export unit values are calculated as price proxies in order to assess export price competitiveness in the region. While demand potentials for locally...

Understanding Zambia’s Domestic Value Chains for Fresh Fruits and Vegetables
Provedor de dados: 31
Autores: Hichaambwa,   Munguzwe; Tschirley,   David L.
The proportion of smallholder households selling horticultural produce is very low suggesting that new demand points could enjoy substantial supply response if they link effectively to the smallholder sector. The small-scale traditional marketing system continues to dominate fresh produce flows in the country. Prices for consumers in this system are much lower, and quality is comparable and sometimes superior to supermarkets. Yet these markets suffer from serious structural problems due to a lack of public investment and little collaboration between public officials and traders in market management. The Urban Markets Development Program represents a major and impressive effort to improve wholesale and retail markets in the country, but has run into...

Assessment of Kenya's Domestic Horticultural Production and Marketing Systems and Lessons for the Future
Provedor de dados: 31
Autores: Tschirley,   David L.; Ayieko,   Miltone W.
After reviewing trends in the production and marketing of fresh produce for the domestic market in Kenya since 1997, this paper presents detailed information on the structure of the flow of this produce from rural areas to wholesale markets in Nairobi and from those wholesale markets to assorted retail markets. Market shares are estimated by product for geographic areas supplying Nairobi, and for each important wholesale and retail market in the city. It is found that horticultural production for the domestic market is keeping up with rural population growth but not with the much faster urban population growth. The urban wholesaling and retailing system has decentralized dramatically and with little planning over the past two decades in response to lack of...

Semi-Parametric Modeling of Investments in Energy Installations
Provedor de dados: 31
Autores: Oude Lansink,   Alfons G.J.M.; Pietola,   Kyosti.
This paper applies a semi-parametric approach to estimating a generalised model of investments in energy installations. The model accounts for irreversibility and lumpiness of investments by linking a parametric specification of the unobservable dynamic shadow price to observed investment behaviour using a non-parametric specification of the adjustment cost function. The results suggest that marginal costs of investments in energy installations increase quickly at small investment levels, whereas the increase slows down at higher investment levels. Therefore, standard parametric adjustment cost models are likely biased such that they over-estimate small investments and under-estimate large investments.

Provedor de dados: 31
Autores: Alvisi,   Franco; Bagnara,   Gian Luca.
The EU policy in horticulture has switched its aim from price support to integration of farmers' income. Regulation 2200/96 established the new European Market Regulation (CMO) in horticulture. On this base the producers' organizations (PO) are no longer a political institution but a real economic organization with the objectives of planning and concentrating the production. At the same time, the UE has promulgated another plan (Decision n.2796 of 10/10/96 applying the objectives of the Reg. 2081/93), which is specific for Italian regions in "Objective 1" namely with low average income. This issue establishes the commercial macro organizations with the target of concentrating the supply of the producers' organizations in order to achieve countervailing...

Producing and Procuring Horticultural Crops with Chinese Characteristics: Why Small Farmers Are Thriving and Supermarkets Are Absent in Rural China
Provedor de dados: 31
Autores: Wang,   Honglin; Dong,   Xiaoxia; Huang,   Jikun; Rozelle,   Scott; Reardon,   Thomas.
The supermarket revolution has arrived in China and is spreading as fast as or faster than anywhere in the world.  As the demand for vegetables, fruit, nuts and other high valued products have risen, urban retailers are finding new venues seized on niche and today have over $55 billion in sales, more than a third of the urban food market.  However, the experience of many developing countries suggests that there could be serious distributional impacts of the rising of supermarkets.  There is concern among policy makers and academics that poor, small farmers might be excluded from market.  The main goal of our paper is to understand what types of farmers have been able to participate in the horticultural revolution, how they interact with markets and how...

Opportunities for Producing Table Grapes in Egypt for the Export Market: A Decision Case Study
Provedor de dados: 31
Autores: Diab,   Yaser A.A.; Mousa,   Magdi A.A.; Warnock,   Daniel F.; Hahn,   David E.
The Barakat Fruit Farm desires to increase their share of the exportable grape market in Egypt. Unfortunately, the grape cultivars currently cultivated by the farm bear fruit after the early market window to the European Union when prices are high. An analysis of the company, competition, consumer, market channel, and conditions, provides insight into possible solutions to the challenges faced by the farm management. Designed for undergraduate classroom use, this case encourages students to think outside of traditional production techniques to arrive at solutions that are viable from both crop culture and financial standpoints.

What do we mean when we say casualisation of farm work is rising?: Evidence from fruit farms in the Western Cape
Provedor de dados: 31
Autores: Conradie,   Beatrice.
Du Toit &amp; Ally's (2003) results on the casualisation of farm work in the Western Cape confirmed the worst fears of sociologists: Globalisation and/or labour laws increased casualisation in agriculture. New labour data and a study conducted in 1976 allow one to revisit the casualisation result for the table grape industry of the Hex River Valley. This paper resolves imprecise definitions of regular versus permanent status, and of casual versus seasonal status. It also examines casualisation and job shedding. Results show a decrease in the share of seasonal work and no change in the casual component of seasonal work. The job status of most farm women in the Valley improved as a result of legislative changes implemented since 1994. Outsourcing is present...

Are Horticultural Exports a Replicable Success Story? Evidence from Kenya and Côte d'Ivoire
Provedor de dados: 31
Autores: Minot,   Nicholas; Ngigi,   Margaret.
Kenyan horticultural exports are often cited as a success story in African agriculture. Fruit and vegetable exports from Côte d’Ivoire have received less attention, but the export value is similar to that of Kenya. This paper focuses on three questions. First, do the horticultural sectors of Kenya and Côte d’Ivoire constitute valid success stories? Second, what factors have contributed to the success (or lack thereof)? And third, to what degree can the success be replicated in other African countries? The paper finds that Kenyan horticultural exports are indeed a success story: horticulture has become the third largest earner of foreign exchange, more than half the exports are produced by smallholders, and smallholders gain from producing for the export...

Impact of Contract Farming on Income: Linking Small Farmers, Packers, and Supermarkets in China
Provedor de dados: 31
Autores: Miyata,   Sachiko; Minot,   Nicholas; Hu,   Dinghuan.
Contract farming is seen by proponents as a way to raise small-farm income by delivering technology and market information to small farmers, incorporating them into remunerative new markets. Critics, however, see it as a strategy for agribusiness firms to pass production risk to farmers, taking advantage of an unequal bargaining relationship. There is also concern that contract farming will worsen rural income inequality by favoring larger farmers. This study examines these issues in Shandong Province, China, using survey data collected from 162 apple and green onion farmers and interviews with four contracting firms in 2005. Using a probit model to estimate participation in a contract-farming scheme, we find little evidence that contracting firms prefer...

Policy interventions to promote the adoption of water saving sprinkler systems: the case of lettuce on the Gnangara Mound
Provedor de dados: 31
Autores: Brennan,   Donna C.
The potential for improving irrigation scheduling decisions and adoption of more efficient irrigation systems is explored using a bioeconomic simulation model of lettuce production on the Gnangara Mound near Perth, Western Australia. Sandy soils with poor water and nutrient holding capacity are associated with declining marginal productivity of water at high water use, which would create an incentive to reduce water use and to adopt closer sprinkler spacing if farmers had correct information about the declining marginal productivity of water. Incorrect perceptions regarding water–yield relationships lead to over use of water by up to 50 per cent and reduce profits by $475 per crop hectare (12 per cent) in the short run, and remove the incentive to adopt...

Autores: Taragola,   Nicole; Van Lierde,   Dirk; Van Huylenbroeck,   Guido.
In Flanders glasshouse vegetables and ornamental plants are typically produced at family businesses. At this type of businesses the objectives and long-term firm developments are influenced by the so called ‘family-firm life cycle’. In many cases the firm shows a life cycle that corresponds with the life cycle of the entrepreneur. The objective of the paper is to test the hypothesis that the ‘family-firm life cycle’ will have an impact on the personal and business characteristics, objectives and the quality of the management processes involved in sustainable glasshouse horticulture. As sustainable horticulture integrates the three P’s (People, Planet, Profit) special attention is paid to human resource, environmental and financial management. Data for the...

This paper has examined Pareto efficiency of household resources allocation and the appropriateness to use gender-specific models rather than unitary model while investigating economic performance of men and women managers of separate plots within horticultural households in Senegal, West Africa. This paper contributes to the gender and economics literature providing empirical evidence of intrahousehold resources allocation in a specific social, economic and cultural context in which polygamy occurs and where husband and wives manage separately their plots. The findings confirm the suitability of gender-specific models to shed light on the gender differential of performance. As the subject matter is efficiency, as well in econometric as in economic point...

ASSESSING KOSOVO'S HORTICULTURAL POTENTIAL - THE MARKET FOR FRUIT AND VEGETABLES ON THE BALKANS
Provedor de dados: 31
Autores: Fischer,   Christian.
SUMMARY Kosovo had been a net exporter – at least of some – fruit and vegetables in the former Federal Republic of Yugoslavia before the civil war. Current reconstruction efforts therefore focus on restoring the past horticultural potential of the now independent province. This paper analyses the competitiveness of the Kosovar fruit and vegetable sector. By calculating average net trade flows during 1996-2000 for more than 20 individual fruit and vegetables and seven ag-gregates, demand potentials for the Balkan regional market are identified for potatoes, lettuce, garlic, dried beans and pears. In addition, average export unit values are calculated as price proxies in order to assess export price competitiveness in the region. While demand potentials for...

Horticultural Households Profit Optimization and the Efficiency of Labour Contract Choice
Provedor de dados: 31
Autores: Ndoye Niane,   Aifa Fatimata; Burger,   Kees; Bulte,   Erwin H.
In agriculture, the coexistence of different forms of land tenancy or labour contract has been explained so far by several theories related to Marshallian inefficiency, incentives, risk sharing, and transaction costs, including supervision costs. These theories and the empirical evidences have greatly contributed to explain the reasons behind land tenancy or labour contract choice. This study follows up on this. Moreover, it intends to take a further step by focusing particularly on the production technologies at plot level, and by designing and testing a theoretical model based on household profit optimization. This model will take into account the supervision costs of labour (i) to compare optimum profit derived from plots based on household labour, a...

Supermarket market-channel participation and technology decisions of horticultural producers in Brazil
Provedor de dados: 123
Autores: Mainville,Denise Y.; Reardon,Thomas.
This paper examined the relationships between growers’ choice of market channel (emphasizing the supermarket market-channel versus others), technology use, and grower characteristics such as human capital and farm size. Three key findings emerged. First, both tomato and lettuce growers selling to the supermarket market-channel had more human capital than those not participating. Second, while farm size was important in whether lettuce growers sell to supermarkets, it was not important for tomato growers. Third, technology use was significantly more capital-intensive among lettuce growers selling to the supermarket channels, however, that was generally not the case for tomato growers. These results are important to agribusiness researchers and policymakers...

Abstract Agriculture has been progressing continuously, from the use of free natural resources to the fossil fuels as energy sources. Even though agriculture depends mainly on ecosystem resources and services, its development has been apparently centered only on yield, not considering neither the ecological value of the negative externalities nor the decapitalization of the resources that influence sustainability. Thus, the information on the evaluation of the sustainability on different agriculture styles is scarce or almost null. This investigation evaluates the sustainability in different agriculture styles (intensive horticulture, traditional farm and self-sustaining horticulture) established in Hualqui (Region of Biobío, Chile), through the energy...

PHOTOSYNTHETIC PERFORMANCE AND LEAF WATER POTENTIAL OF GULUPA (Passiflora edulis Sims, PASSIFLORACEAE) IN THE REPRODUCTIVE PHASE IN THREE LOCATIONS IN THE COLOMBIAN ANDES
Provedor de dados: 37
Autores: PEREZ MARTINEZ,Laura Victoria; MELGAREJO,Luz Marina.
Gulupa, Passiflora edulis Sims (Passifloraceae), is an important fruit due to its organoleptic and nutritional characteristics and its demand in the international market; however, very few studies have been conducted for studying its Ecophysiology. Until now, this crop has spread throughout the country through empirical knowledge without data that indicate the zones that are more suitable for its cultivation. For this reason, gas exchange, chlorophyll fluorescence (photosystem II operating efficiency and maximum quantum efficiency of photosystem II photochemistry) and leaf water potential were measured in three different locations of Cundinamarca department (Chia [2610 m a.s.l., 14 °C], Granada [2230 m a.s.l., 15 °C] and Tena [2090 m a.s.l., 17 °C]), whose...

 The objective of this study was to evaluate the effects of a biostimulant on gherkin seeds, cultivar Liso de Calcutá, under conditions of salt stress. A split-plot experimental design with five replications was used; the main plot was represented by two levels of irrigation water salinity (0.5 and 3.5 dS m-1), and the subplot was composed of five biostimulant doses applied as a seed treatment (0, 5, 10, 15, and 20 mL kg-1). The following variables were evaluated: the number of leaves; number of branches; length of the largest branch; leaf, stem, fruit and total dry matter; number of fruits; average fruit weight; and fruit production. The values of all analyzed variables decreased with an increase in irrigation water salinity regardless of the biostimulant...

Provedor de dados: 111
Autores: Leiva, Josue Nahun; Robbins, J.; Saraswat, D.; She, Y.; Ehsani, R.
Separate experiments were conducted to evaluate the effect of plant canopy shape and presence of flowers on counting accuracy of container-grown plants.  Images were taken at 12 m above the ground.  Two species of juniper (Juniperus chinensis L. ‘Sea Green’ and Juniperus horizontalis Moench ‘Plumosa Compacta’) were selected to evaluate plant shape and Coral Drift ® rose (Rosa sp. ‘Meidrifora’) was used to evaluate the presence of flowers on plant count.  Counting algorithms were trained using Feature Analyst (FA).  Total counting error, false positives and unidentified plants were reported. There was no difference between all variables measured when an algorithm trained with an image displaying regular or irregular plant canopy shape was applied to images...

Water application in the plant house is usually done by surface irrigation and manual micro-irrigation. Because of the conventional irrigation system’s inefficiency, water-saving irrigation has been developed. Smart or automated irrigation usually uses a microcontroller to maintain irrigation timing and soil moisture conditions. This automation is highly efficient in water application and can increase plant productivity. However, this system is costly and the irrigation components are not always available for smallholder farmers. Here we develop an automatic irrigation technology based on the capillarity principle that dramatically reduces the cost. This irrigation technology does not use any microcontroller device and the components can be easily...

Provedor de dados: 65
Autores: Ramos-López,Bernabé Ignacio; Ortiz-Hernández,Yolanda Donaji; Morales,Isidro.
ABSTRACT: Physalis ixocarpa (husk tomato) is traditionally cultivated in Mexico, and nowadays the yield is low. In this study, four cultivars of husk tomato were evaluated, under greenhouse and field conditions. It was carried out a split-plot experimental design in a 4x2 factorial arrangement. The large plot was the growth conditions and the small plot was the variety. The microclimate, soil and yield variables were recorded. In the field, the Integrated Photosynthetic Active Radiation (IPAR) was higher 12mol m-2 d-1 than in the greenhouse. The average temperature was slightly higher 1.18°C in the greenhouse and the average relative humidity was slightly higher 0.89% in the field. Plants grown in the greenhouse had lower negative values for the matric...
