The use of soluble phosphate fertilizers applied foliar application can increase the amount of phosphorus available to the plant and increase the productivity of the crop planted. This study aimed to evaluate the efficiency of MAP Purificado® and Intacto® foliar phosphatic fertilizers on soybean yield. Both products contain 61% phosphorus and 12% nitrogen. The experiment was conducted at the experimental farm of the Federal Institute of Tocantins – Colinas do Tocantins Campus. A randomized block design was used, consisting of six treatments and four replications. Purified MAP was assessed at doses of 1 kg.ha-1 and 2 kg.ha-1, while Intacto was applied at doses of 0.25 L.ha-1, 0.5 L.ha-1, and 1 L.ha-1, along with a control treatment without fertilization. The products were applied at the vegetative growth stages V4 and V8 of the soybean crop. The useful plot area was 6 m², where plant height, chlorophyll A and B content, thousand-grain weight, and crop yield per hectare were evaluated. Data were subjected to analysis of variance (ANOVA) for mean comparison, followed by Tukey’s test at a 5% significance level, using the statistical software Speed Stat 2.7. Statistically, there was no sufficient evidence that all six treatments differed from each other. However, the 1 kg.ha-1 purified MAP treatment consistently outperformed the other treatments, producing six additional soybean bags compared to the control treatment. The doses tested in this study did not show any statistical difference for the variables analyzed. It is concluded that, under the conditions in which this study was carried out, both MAP Purificado® and Intacto® do not significantly interfere with soybean productivity factors.Downloads
