“…The calculation was based on the reference evapotranspiration (Eto, mm/day), estimated by the class A tank and corrected by the Kc of culture according to the development stage of the plant, obtaining the consumptive use (Cu) considering the wet area percentage = 50%. The variables assigned in the experiment were: coefficient of class A tank (Kp) = 0.75 and varying crop coefficients according to the culture stage were used as Paes et al (2012).…”

A field study was conducted to explore the effect of various rates of organic matter, two water depths, with and without mulching on production of okra (Abelmoschus esculentus L.) and leaf nutrient content. This study was done for two years, and the experimental design of randomized blocks in a factorial 5 ˟ 2 ˟ 2 was used, with four replications. The treatments were five rates of organic matter, necessary for raising the levels of organic matter in the pits to 1.8, 2.62, 3.44, 4.26 and 5.08%, two water depths (50 and 100%) of crop evapotranspiration, and soil with and without mulch. In general, it can be observed that the results in the two experimental periods are similar; foliar contents and fruit yield were higher in the plants irrigated with greater amount of water, and also increased with the application of organic matter to the soil. The results were not very different with and without soil mulch, since, with the growth of the plants, the canopies of the same shaded the soil avoiding the evaporation of the water.

“…The small producers are the main responsible for much of the production of this vegetable. As a result of the increasing consumer preference, there has been a significant expansion of the okra in Brazil, especially in the states of Rio de Janeiro, São Paulo and Sergipe (CAVALCANTE et al, 2010;PAES et al, 2012).…”

The objective of this work was to determine the irrigation levels that result in the maximum productivity and efficient use of water for the cultivation of okra. The experiment had five irrigation levels (25, 50, 75, 100 and 125% of crop evapotranspiration-ETc) and a control plot that did not receive irrigation. The experimental design was in randomized blocks, with four replications. Irrigations were applied through a drip system and for irrigation management, the FAO Penman-Monteith standard method was used to estimate the reference evapotranspiration, and crop evapotranspiration was obtained through a constant water table lysimeter installed in the area experimental. The productivity was obtained considering the production of the useful area of each plot with subsequent conversion to kg.ha -1 . The efficiency of water use was determined by dividing the amount produced in kg of fruits per millimeter of water applied in okra culture. The application of different irrigation levels influenced in a significant way the variables analyzed in this experiment.

As irrigações foram aplicadas através de um sistema de gotejamento, e para o manejo da irrigação, o método padrão da FAO Penman-Monteith foi utilizado na estimativa da evapotranspiração de referência e a evapotranspiração da cultura foi obtida através de um lisímetro de lençol freático constante instalado na área experimental. A produtividade foi obtida considerando a produção da área útil de cada parcela com subsequente conversão em kg. ha -1 . A eficiência de uso da água foi determinada pela divisão da quantidade produzida em kg de frutos por milímetro de água aplicada em cultura de quiabo. A aplicação de diferentes níveis de irrigação influenciou de forma significativa as variáveis analisadas neste experimento.

ABSTRACT:The objective of the present study was to evaluate the production of okra under different levels of irrigation, in the Northeast region of Brazil, Sergipe state. The experiment had five irrigation levels (25, 50, 75, 100 and 125% of crop evapotranspiration-ETc) and a control plot that did not receive irrigation. The experimental design was in randomized blocks, with four replications. Irrigations were applied via a drip system and for irrigation management, the FAO Penman-Monteith standard method was used to estimate the reference evapotranspiration, and crop evapotranspiration was obtained through a constant water table lysimeter installed in the area experimental. The following characteristics were evaluated: average fruit diameter, average fruit length, yield per plant and productivity. The application of different levels of irrigation influenced in a significant way the variables analyzed in this experiment.
