CULTURE OF THE OKRA (Abelmoschus esculentus) SUBMITTED TO DIFFERENT IRRIGATION LEVELS

Abstract

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.

O experimento teve cinco níveis de irrigação (25, 50, 75, 100 e 125% da evapotranspiração-ETc) e uma parcela de controle que não recebeu irrigação. O delineamento experimental foi em blocos casualizados, com quatro repetições. As irrigações foram aplicadas através de um sistema de gotejamento, e para o
