Abstract

The aim of this study was to evaluate the quality of peanut seeds according to the application of B via leaf and associated with soil. The experiments were carried out in a sugarcane reform area in the municipality of Ribeirão Bonito-SP, in the 2018/19 agricultural year. The study was carried out in a randomized block design with 4 replications. In the first experiment, folic acid applications were applied (Bab: doses 0, 250, 500, 750, 1000 and 1250 g ha-1). While, in the second experiment, he applied sodium octaborate, via soil, (Boct: dose 500 g ha-1), associated with the application of boric acid, via leaf (Bab: doses 0, 250, 500, 750, 1000 and 1250 g ha-1 of B). The plots were 3.6 meters wide, with 4 planting lines spaced 0.90 m apart, 20 meters long and an average stand of 12 plants per meter. The cultivar used was IAC OL4. Planting was carried out on October 10, 2018, with the plucking 127 days after planting. The application of boron via leaf occurred in three moments: 30, 45 and 60 days after the emergence (DAE) of the culture. In the association B soil and leaf, the application of B via soil was done using a plant-apply system right after planting. Leaf applications of doses of 500, 750 and 1,000 g ha-1 of leaf B, increase the germination percentages of normal seedlings. Therefore, the association of B via soil and leaf at doses of 250, 500, 750, 1,000 and 1,250 g ha-1 of B, results in germination percentages of normal seedlings with constancy and superiority of 88% and of abnormal seedlings below 9%, when compared to foliar application only, in soil with low B content (<0.12 mg dm-3).
