RESPONSE OF RABANET CULTURE UNDER ORGANIC CULTIVATION TO PRODUCTION FACTORS WATER AND SOIL COVERAGE

Abstract

In regions with limited water resources, such as the semi-arid region of Ceará, the efficient use of water becomes indispensable every day for the production of irrigated vegetables in this region. In this sense, the present research had as objective the technical and economic evaluation of the effect of the factors of production water and levels of cover of the soil of the bagana on the productivity of the radish culture. The research was conducted in the period from June to August of 2018 in two production cycles in area belonging to Prece (Cooperative Cell Education Program), located in the municipality of Pentecoste-CE. The experiment was conducted in a randomized block design with four replicates. The treatments consisted of five irrigation slides (50%, 75%, 100%, 125% and 150% of crop evapotranspiration, ETc) and five different levels of mulch consisting of carnauba bagana: 25%; 50%; 75% and 100% beyond the control with the soil without 0% coverage, totalizing 100 experimental units. The results allowed to conclude that the carnauba bagana presented potential for use as mulch in the cultivation of radish, providing an increase in the yield of the crop under conditions of deficit irrigation strategy. The radish culture responds significantly to the different irrigation slides, and it is possible to use deficit strategies when associated with the use of mulch in the soil.
