“…The higher broccoli biological yield in I 0.8 was due to more quantity of water application thereby improving the plant shoot and root growth parameters which resulted in increase nutrient uptake in comparison to I 0.4 and I 0.6. Similar findings were also reported by Gadissa and Chemeda (2009) and Jayapiratha et al, (2010). Different fertilizer application methods significantly affected the curd yield of broccoli.…”

RESUMOObjetivou-se, neste trabalho, avaliar as tensões de água no solo em duas fases fenológicas (vegetativa e reprodutiva) da cultura da pimenta Cayenne, cultivada em ambiente protegido e irrigada por gotejamento. Foram instalados dois experimentos utilizando-se um delineamento inteiramente casualizado cujos tratamentos foram definidos por quatro tensões de água no solo (20, 40, 60 e 120 kPa) e quatro repetições. Os maiores valores de massa média de frutos por planta foram obtidos para a tensão de 20 kPa, sendo 1936,83 e 2091,59 g por planta e os coeficientes de rendimento obtidos foram 0,81 e 1,01, para as fases vegetativa e reprodutiva, respectivamente. Com base nos resultados apresentados concluiu-se que: a produtividade da cultura apresentou comportamento inversamente proporcional à tensão de água no solo e a tensão de 20 kPa mostrou-se mais adequada para promover as irrigações nas fases estudadas. Os coeficientes de rendimento identificaram a fase reprodutiva como a mais sensível ao deficit hídrico.

A completely randomized design was used, using four soil water tensions (20, 40, 60 e 120 kPa) as treatments with four replications, in two experiments (1 e 2), related to the phenological stages (vegetative and reproductive), respectively. The higher values of fruits mean weight per plant were obtained with 20 kPa soil water tension, being 1,936.83 and 2,091.59 g plant -1 and the yield coefficients obtained were 0.81 and 1.01, for vegetative and reproductive stages, respectively. It was concluded that the crop yield presented inversely proportional behavior to the soil water tension, and the 20 kPa tension showed most appropriate to promote the irrigation on the studied stages. The yield coefficients identified the reproductive stage as the most sensitive to the water stress.

“…In the bell pepper crop, the number of flowers has high and positive correlation with the number of branches (Gadissa & Chemeda, 2009). Hence, flower abortion increased with the increment in the number of branches, which was evidenced at the highest irrigation depths.…”

“…* and ** Significant at 0.05 and 0.01, respectively, by F test Under field conditions, an increasing linear function explained the same variable as a function of the irrigation depths for bell pepper (Lima et al, 2012) and pepper (Gadissa & Chemeda, 2009, Azevedo et al, 2005. However, the small amplitude of the irrigation depths used by Lima et al (2012) may have not been sufficient to reach the maximum value of fruit production.…”

A B S T R A C TWater 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 evaluated the root dry matter, total fruit production, leaf temperature, number of aborted flowers and water use efficiency. The interaction between both effects was not significant for any of the variables. The effect of methodology was observed only on the number of aborted flowers. The effect of the irrigation depths was significant on all variables. The irrigation depths that lead to the best agronomic characteristics were superior to 100% of ETc. The ratio between the irrigation depths estimated by single-Kc and dual-Kc methodologies was 1.14. Single-Kc methodology and irrigation depth of 143% ETc were more suitable for the horticulturist. The most efficient irrigation depth in the use of water was 105% ETc.Resposta da cultura do pimentão a lâminas de irrigação calculadas por diferentes metodologias R E S U M OA água deve ser fornecida na quantidade certa e no momento oportuno às culturas. As hortaliças requerem uma boa disponibilidade de água no solo durante todo o ciclo, portanto, se tornam primordial a implementação do manejo da irrigação e a estimativa precisa do requerimento de água pela cultura. Dessa forma, o objetivo deste trabalho foi avaliar o efeito de cinco lâminas de irrigação estimadas pelas metodologias de Kc duplo e Kc único sobre as características de crescimento, produção e eficiência no uso da água na cultura do pimentão. Adotou-se o delineamento em blocos casualizados, no esquema de parcelas subdivididas. Na parcela foi avaliado o efeito de cinco lâminas de irrigação (50, 75, 100, 125 e 150% da evapotranspiração da cultura -ETc) e na subparcela, as metodologias. Foram avaliadas massa seca de raízes, produção total de frutos, temperatura foliar, número de flores abortadas e eficiência no uso da água. A interação entre os dois efeitos não foi significativa para nenhuma das variáveis. O efeito da metodologia somente foi observado para a variável número de flores abortadas. O efeito das lâminas de irrigação foi significativo para todas as variáveis. As lâminas que proporcionam as melhores características agronômicas foram superiores a 100% da ETc. A razão entre as lâminas estimadas pelas metodologias de Kc duplo e Kc único foi de 1,14. A metodologia de Kc único e a lâmina de 143% da ETc foi mais indicada para o horticultor. A lâmina de i...
