Produtividade do amendoim de segunda safra em diferentes épocas de semeadura

Abstract

In the Northeast region, peanuts represent a subsistence alternative for farmers who face adverse weather conditions. Thus, the study aimed to evaluate the productivity of second-crop peanuts at different sowing times in the edaphoclimatic conditions of the municipality of Uruçuí, Piauí. The experiment was conducted in the experimental area of the Escola Farm on the Uruçuí Campus. A completely randomized design was used, in a 2 x 3 factorial scheme, with two harvests and three sowing times, with four replications. The soil was prepared with a plow harrow with 28” discs and fertilized according to the recommendations for the crop. Each plot consisted of 4.5 m2, with three lines of 3 meters and a spacing of 0.5 m. Sowing was manual, using cv. Horse, with 8 seeds per line. The variables analyzed were pod productivity, shelled peanut productivity and yield. There was an interaction between harvests and sowing times for productivity in pods and productivity of shelled peanuts. In both productivity assessments, the first season presented the highest average, regardless of the harvests. When evaluating sowing
