| 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... |

| ABSTRACT The aim of this study was to evaluate four strains of Trichoderma spp. (T. harzianum IBLF 006 WP, T. harzianum IBLF 006 SC, T. harzianum ESALQ 1306 and T. asperellum URM 5911) for seedling growth promotion in laboratory and head lettuce yield in field conditions. The experiment was carried out in a completely randomized design with four treatments (strains): IBLF 006 WP, IBLF 006 SC, ESALQ 1306 and URM 5911 and a non-inoculated (without Trichoderma) control. Each treatment consisted of 200 seeds, arranged in four replicates. Lettuce seeds cv. Astra were treated with 2 mL Trichoderma suspension (2.5 x 108 conidia mL-1 per each 100 g seeds) and submitted to growth assay in laboratory up to 7 days after sowing. For field experiment, we opened... |

| ABSTRACT Studies on plant nutrition are essential for a correct fertilizer management, improving yield and quality of the product, and it also may contribute for an updating recommendation. The aim of this study was to evaluate growth, nutrient accumulation and export, thermal sum and yield of zucchini cultivar Corona F1. The experiment was carried out from August 8 to October 25, 2013, in Santo Antônio de Posse, São Paulo State. At the end of the research, 84 days after transplanting (DAT), we observed 95 cm average height with 36 leaves and 45.8 t ha-1 maximum yield. The nutrient accumulation, in g plant-1, was: N (14.2) > K (9.3) > Ca (8.0) > Mg (2.5) > S (1.2) > P (0.9) and in mg plant-1, Mn (49.3) > Fe (34.9) > Zn (19.6) > B... |

| 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... |

| 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... |

| 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... |

| 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... |

| ABSTRACT The region of Viçosa in Brazil stands out for vegetable production. For success in this activity, the correct choice of cultivar with the correctly applied irrigation are necessary. As such, the aim of this study was to evaluate the agronomic performance of radish cultivars submitted to different irrigation depths. The radish crop was grown in a protected environment over three cycles, for periods of 38 to 40 days. The experimental design was of randomised complete blocks in split plots with five replications, comprising five irrigation depths (50, 75, 100, 125 and 150% of crop evapotranspiration-ETc) in the plots, with three radish cultivars in the subplots. (Hybrid no 25 - Sakata, Crunchy Royale - Sakata and Vip Crimson - Feltrin). A drip... |

| Horticultural production areas are favorable to development and maintenance of land mollusks populations. To know the mollusk fauna diversity in that kind of production area a research project was conduced in a rural-urban district of Porto Alegre, Rio Grande do Sul, Brazil. The production property studied is located in the Southern zone of the city and has 17 ha of cultivated area. The sampling period was from August/2000 to August/2001, with monthly quantitative collects on the different culture production beds previously selected. Six taxa were registered: Deroceras leave (Müller, 1774) (1.389 specimens = 82,82%), Bradybaena similaris (Férussac, 1821) (195 specimens = 11,7%), Succinea meridionalis d'Orbigny, 1846 (82 specimens = 4,9%), Lamellaxis... |

| 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... |
