Provedor de dados: 75
Autores: Ragassi,Carlos Francisco; Zucolotto,Juliana; Gomes,Lucas M; Ribeiro,Cláudia SC; Madeira,Nuno Rodrigo; Reifschneider,Francisco José B.
ABSTRACT Mechanizing the harvest of Jalapeño pepper involves changes in the production system. Spacings between plants in rows (10 to 40 cm; 60 cm fixed between rows) were evaluated in relation to plant architecture, productivity and fruit quality of cultivar BRS Sarakura during three years, in a randomized complete block design with five replicates. Productivity (41.9 to 78.8 t ha-1) and plant height (40.1 to 47.3 cm) responded linearly to density; on the other hand, productivity per plant responded negatively (0.48 to 1.04 kg plant-1). The stem first bifurcation height was little influenced. Fruit chemical analyses were carried out in the second year of the experiment; spacing significantly influenced pH (5.36 to 4.84), total titratable acidity (TTA)...

Guia prático de manejo de açaizais para produção de frutos.
Provedor de dados: 14
Autores: QUEIROZ, J. A. L. de; MOCHIUTTI, S.
O açaizeiro (Euterpe oleracea, Mart.) é uma palmeira que ocorre nas florestas de várzea do estuário amazônico e em áreas úmidas de terra-firme, chamadas de grotas. Nas várzeas do estuário amazônico, os açaizeiros apresentam grandes densidades e trouçeiras com elevado número de estirpes, convivendo em harmonia com as demais espécies que ocorrem na floresta. Neste ambiente a produção de frutos é boa e ocorre naturalmente durante o ando todo, sendo que em alguns meses há produção de muitos frutos e em outros meses produção de poucos frutos, o que resulta em grande oscilação em seu preço.

Autores: Sangoi,Luís; Ender,Márcio; Guidolin,Altamir Frederico; Almeida,Milton Luiz de; Heberle,Pedro Canísio.
The interest in reducing maize row spacing in the short growing season regions of Brazil is increasing due to potential advantages such as higher radiation use efficiency. This experiment was conducted to evaluate the effect of row spacing reduction on grain yield of different maize cultivars planted at different dates. The trial was conducted in Lages, in the State of Santa Catarina, Brazil, during 1996/97 and 1997/98 growing seasons, in a split-split plot design. Early (October 1st) and normal (November 15) planting dates were tested in the main plot; two morphologically contrasting cultivars (an early single-cross and a late double-cross hybrids) were evaluated in the split plots and three row widths (100, 75 and 50 cm) were studied in the split-split...

Cuticle and cuticular wax development in the sunflower (Helianthus annuus L.) pericarp grown at the field under a moderate water deficit
Provedor de dados: 85
Autores: Franchini1,MC; Hernández,LF; Lindström,LI.
Wax in the sunflower (Helianthus annuus L.) pericarp is an important morphological feature that interferes with oil quality and varies with crop management and environmental conditions. We studied the effect of a moderate water deficit (MWD) generated from early to late anthesis on quantitative development of the cuticle, and qualitative and quantitative development of the cuticular waxes (CW) of the pericarp in two hybrids grown under field conditions. The experiment was repeated during two consecutive seasons (Exp-I and Exp-II). At harvest maturity (HM), plants grown under a MWD showed higher CW content (31 to 47%) and thicker cuticles (13%) in both experiments compared to controls. Epicuticular wax (ECW) crystals showed a granular morphology. Also a...

Provedor de dados: 31
Autores: Mukherjee,   Sacchidananda; Nelliyat,   Prakash.
Industrial disposal of effluents on land and the subsequent pollution of groundwater and soil of surrounding farmlands – is a relatively new area of research. The environmental and socioeconomic aspects of industrial effluent irrigation have not been studied as extensively as domestic sewage based irrigation practices, at least for a developing country like India. The disposal of effluents on land has become a regular practice for some industries. Industries located in Mettupalayam Taluk, Tamil Nadu, dispose their effluents on land, and the farmers of the adjacent farmlands have complained that their shallow open wells get polluted and also the salt content of the soil has started building up slowly. This study attempts to capture the environmental and...

A Practical Algorithm for Multiple-Phase Control Systems in Agricultural and Natural Resource Economics
Provedor de dados: 31
Autores: Doole,   Graeme J.
Many important problems in agricultural and natural resource economics concern an intertemporal choice between alternate dynamic systems. This significance has motivated a theoretical literature generalizing the necessary conditions of Optimal Control Theory to multiple-phase problems. However, gaining detailed insight into their practical management is difficult because general numerical solution methods are not available. This paper resolves this deficiency through the development of a flexible and efficient computational algorithm based on a set of necessary conditions derived for finite-time, multiple-phase systems. Its effectiveness is demonstrated in an application to a nontrivial crop rotation problem.

Irrigation development has been identified as a means to stimulate economic growth and rural development in Ethiopia. However, little attempt has been made to quantify the contribution of irrigation to national income. Using data from selected irrigation schemes, representing small, medium and large-scale schemes of modern or traditional typologies; the present coverage and planned growth of irrigation, actual and expected contributions of irrigation to the national economy were quantified following the approach of adjusted gross margin analysis. Our results show that irrigation yields 219.7% higher income compared to the rainfed system while its current and future contribution to agricultural GDP is estimated to be about 5.7 and 12% although irrigation...

MANAGEMENT DECISIONS ON FARM-LEVEL AND THEIR LINK TO WEATHER REQUIREMENTS: A CASE STUDY FOR THE UPPER DANUBE RIVER BASIN
Provedor de dados: 31
Autores: Apfelbeck,   Josef; Huigen,   Marco; Krimly,   Tatjana; Sanchez,   G.C.
It is undeniable that the global warming has already affected the Earth’s biota, whereby the rise of air temperature is an important factor. Agricultural systems are also affected by climate change via the interrelated biophysical layers. Climate influences farmers` decisions in crop management. To simulate the interactions between climate/weather and the different crop management activities an agent based modelling approach is used, in which farmers` decision making is based on crop requirements from literature. To validate these decision algorithms on how farmers arrange their daily crop management decisions like planting, fertilizing, and harvesting due to changes of climate parameters, a statistical analysis of empirical data (1970-2003) on temperature...

Provedor de dados: 124
Autores: Echer,Márcia de Moraes; Guimarães,Vandeir Francisco; Inagaki,Adriano Mitio; Dalastra,Graciela Maiara; Hachmann,Tiago Luan.
ABSTRACT The aim of the present study was to verify changes in the levels of photosynthetic pigments as well as gas exchange in the Fuyutoyo and Red Cabbage cultivars, grown under no-tillage (NT) and conventional (CT) systems. A randomised block design with four replications was used, in a 2 x 2 factorial scheme, where the Fuyutoyo and Red Cabbage cultivars were evaluated under two tillage systems. The levels of chlorophyll a, chlorophyll b, total chlorophyll and anthocyanins in the leaves were evaluated in triplicate. Localised gas exchange was measured at different times of the day, together with different photosynthetic photon flux density curves (PPFD). The Fuyutoyo cultivar showed a higher mean value for chlorophyll a (34.58%), chlorophyll b (35.09%)...

Autores: Streck,Nereu Augusto; Lago,Isabel; Bosco,Leosane Cristina; Paula,Gizelli Moiano de; Oliveira,Felipe Brendler; Gabriel,Luana Fernandes; Schwantes,Ana Paula.
Panicle differentiation (DP) is a key developmental stage in rice (Oryza sativa L.) because at this stage plant switches from vegetative to reproductive development and source-sink relation changes to allocate part of the photoassimilates for growing spikelets and kernels. The objective of this study was to determine the main stem Haun Stage (HS) and the number of leaves that still have to emerge until flag leaf at PD in several cultivated rice genotypes and red rice biotypes in different sowing dates. A two-year field experiment was conducted in Santa Maria, Rio Grande do Sul State, Brazil, during the 2005-2006 and 2006-2007 growing seasons, and three sowing dates each year. Nine cultivated rice genotypes and two red rice biotypes were used. PD was...

Herbicide selectivity by differential metabolism: considerations for reducing crop damages
Provedor de dados: 63
Autores: Carvalho,Saul Jorge Pinto de; Nicolai,Marcelo; Ferreira,Renato Rodrigues; Figueira,Antonio Vargas de Oliveira; Christoffoleti,Pedro Jacob.
Herbicide selectivity is an agricultural technology largely exploited in chemical strategies of weed control. The joint action of several protection mechanisms avoids phytotoxicity from herbicide treatment, maintaining the level of agronomically accepted damage to a minimum, or even totally avoiding them. The major mechanism of herbicide selectivity derives from the differential metabolism between weed and crop plant species, with weeds presenting a limited ability to perform it under agronomically recommended conditions. In this case, phytotoxicity can be interpreted as an overcoming of the maximum protection capacity offered by the mechanisms of selectivity, or when considering metabolism as the main factor, the overcoming of the inherent plant ability...

Four-way data analysis within the linear mixed modelling framework
Provedor de dados: 63
Autores: Studnicki,Marcin; Mądry,Wiesław; Derejko,Adriana; Noras,Kinga; Wójcik-Gront,Elżbieta.
Cultivars have to be evaluated under different crop management systems across agro-ecosystems and years using multi-environment trials (MET) before releasing them to the market. Frequently, data collected in METs are arranged according to cultivar (G), management (M), location, (L) and year (Y) combinations in a four-way G x M x L x Y data table that is highly unbalanced for cultivars across locations and time. Therefore, we present the restricted maximum likelihood method (REML) for linear mixed models (LMM) with a factor analytic variance-covariance matrix for assessing cultivar adaptation to crop management systems and environments based on unbalanced datasets. Such a multi-environmental trial system has been in operation in Poland for winter wheat...

Abstract Naranjilla (Solanum quitoense Lam.), is an economic input of vital importance for the Ecuadorian Amazon due to multiple benefits that offers, although it requires studies that provide a basis for the naranjilla cultivation management. The aim of this research was to determine the influence of socioeconomic variables on the naranjilla production from the rural community of Wamani, Napo province in the Ecuadorian Amazon. For the study, a group-type questionnaire was conducted to 40 rural producers of naranjilla in the region, which was structured based on three levels, which included data on the property, crop management and socio-economic aspects. Additionally, a factor analysis was applied to reduce the variables dimensionality. The results showed...

Diversity of parasitoid wasps in conventional and organic guarana (Paullinia cupana var. sorbilis) cultivation areas in the Brazilian Amazon
Provedor de dados: 36
Autores: SCHOENINGER,Karine; SOUZA,Jorge L.P.; KRUG,Cristiane; OLIVEIRA,Marcio L.
ABSTRACT We surveyed parasitoid wasps (Hymenoptera) in two guarana plantations in the central Brazilian Amazon (one conventionally, and one organically managed), as well as in adjacent forest and edge areas between crop and forest. We evaluated differences between management systems in parasitoid diversity and abundance, and assessed the importance of the surrounding matrix as a source of parasitoid wasps for guarana cultivation. Parasitoid wasp richness, abundance and taxonomic composition (at family level) were compared between plantations, and among habitats within plantations. Wasps were sampled using Malaise and Moericke traps. A total of 25,951 parasitoid wasps (10,828 in the conventional, and 15,123 in the organic crop area) were collected, and were...
