| ABSTRACT Arugula is a vegetable that has gained more highlight in the consumption, being rich in potassium, sulfur, iron, omega-3 and vitamins A and C. Availability of water and nutrients are limiting factors for production of this crop. In this context, the objective of this study was to evaluate the production of arugula subjected to different irrigation depths and potassium fertilization. The experiment was conduct between August and September 2015. The experimental design was completely randomized in split-plot scheme. Irrigation depths L1, L2, L3 and L4 (25, 50, 75 and 100% of crop evapotranspiration, respectively) represented the plots and potassium doses K1 and K2 (200 and 400 kg ha-1, respectively) represented the subplots. Although the highest... |

| Devido à importância da cultura do feijão-de-vagem no contexto da agricultura do RJ, a busca por cultivares com maior produção e melhor qualidade é de elevada importância. A determinação da divergência genética, com o uso da análise multivariada, em que diversos caracteres podem ser dimensionados simultaneamente, apresenta-se bastante vantajosa, podendo-se identificar fontes de variabilidade genética, avaliar a importância dos caracteres para a divergência genética, além de permitir aos melhoristas identificar combinações genéticas com maiores chances de sucesso, antes de se realizarem os cruzamentos. Através de técnicas de análise multivariada, verificou-se que acessos de feijão-de-vagem de hábito de crescimento indeterminado, do banco de germoplasma da... |

| ABSTRACT Water must be supplied to a crop in the proper amount and in a timely manner. Vegetables require a good water availability in soil during their entire cycle. Thus, it is very important the implementation of an irrigation management and accurate estimation of water requirement. The objective of this work was to evaluate the effect of five irrigation depths estimated by the dual-Kc and single-Kc methodologies on the characteristics of growth, production and water use efficiency in the pepper crop. A randomized block design was adopted in a split plot arrangement. The effect of five irrigation depths (50, 75, 100, 125 and 150% of crop evapotranspiration - ETc) was evaluated in the plots, and the methodologies were evaluated in the subplots. It was... |

| ABSTRACT Among the determining factors of yield, nitrogen (N) fertilization and the correct supply of water play an important role in the quality and yield aspects of coriander. Therefore, the aim of this study was to evaluate the yield components and the water use efficiency (WUE) in coriander subjected to different depths and N doses. A completely randomized design in split plot was used. Water depths were applied in the plots at the rates of 25, 50, 75, 100 and 125% of the Required Real Irrigation (RRI). N doses were distributed within the subplots at the following proportions: 50, 100 and 150% of the recommendation for the crop (70 kg ha-1). The N dose of 94 kg ha-1 and irrigation depth of 115% of RRI promoted the greatest yield (29.0 t ha-1) and... |
