PRODUÇÃO E QUALIDADE DE SEMENTES DE JILÓ SOB O PARCELAMENTO DA ADUBAÇÃO DE COBERTURA

Abstract

Originally from Africa or jilo is a crop that responds very well to soil fertility, its nutritional qualities, benefits are still poorly studied. Providing nutrients essential for its development in a split form can lead to higher plant productivity, fruit and seed quality. Knowing if the activity to be implemented is viable, it is essential to realize the cost of production that will give the cost-benefit of the product. The objective of this study was to verify the effect of split fertilization on cover on seed yield and quality of jilo fruits. The work was carried out in the experimental field of the Federal Institute Goiano – Campus Ceres and in the Laboratory of Seed Analysis (LSA). For sowing, seeds of the cultivar Tingua Verde-Claro were used. The experimental field design was in randomized blocks, with six treatments, six splittings with fertilizer doses and four replications. Field evaluations, laboratory analysis of seeds and fruits after harvest, and financial viability were performed. The split fertilization of the topdressing did not affect the seed quality, however it provided the highest yield for the jilo crop and a higher number of fruits per plant. The treatment in which the fertilizer was split in six times, presented the highest total cost, however, there was the highest net revenue, higher profitability index and a better cost benefit for the producer. It is recommended to split the fertilizer in coverage for the crop of jilo up to six times.
