FERTILIZER WITH RESIDUAL 3.4-PHOSPHATE DIMETILPIRAZOL (DMPP) ON SOYBEAN CULTIVATION IN SUCCESSION TO INDUSTRIAL TOMATO

Abstract

Aimed to estimate the residual effect of fertilizer application partially covered with polymers and stabilized with 3.4-phosphate dimetilpirazol (DMPP), via soil, for culture of soybean grown in no-tillage system in succession to industrial tomato cultivation. The study was carried out in field condition (latitude 16° 35 ' 48.81" S, longitude 49° 16 ' 41.13"W, altitude of 729 m), under central pivot. The experimental design was of randomized blocks with seven treatments and five replications. The treatments consisted of different combinations of DMPP, NPK (04-30-16), Urea, KCl and foliar fertilizers. It was determined the chemical attributes of the soil, foliar levels and productivity of plants. Soybean culture presents positive relative efficiency index as for increase of productivity for the treatments with greater quantities of fertilizer applied as inhibition of nitrification in residual effect. The application of foliar fertilizer is not efficient for the increase of productivity, either for replacement of base fertilizer.
