MILHO FERTIRRIGADO COM VINHAÇA

Abstract

Nowadays, rural producers encounter several challenges in their crops, especially in the corn harvest, one of the biggest problems is associated with fertilizers, considering scarcity which appears to be even more difficult. Therefore, the work addresses corn production in Brazil, with an emphasis on regions such as Goiás, especially in the off-season. The work highlights the importance of nutrients for corn growth, with emphasis on potassium, and discusses the sources of potassium fertilizer, including the predominant use of potassium chloride. Furthermore, the project explores the possible use of vinasse, a by-product of alcohol production from sugar cane, as an alternative to corn fertilization. Vinasse is rich in potassium and nitrogen, presenting itself as a potential source of nutrients for the crop. The location carried out was in Rio Verde-GO, involving different potassium fertilization, analyzing biometric parameters of the plant, dry matter, productive parameters, and productivity. The experimental design used was in randomized blocks, analyzed in a simple experiment scheme, with 4 replications, totaling 20 experimental plots. T1 = KCl - 100% of the potassium dose applied via potassium chloride at the V4 phenological stage in the corn crop; T2 = Vinasse - 100% of the dose of potassium applied via Vinasse concentrated at the V4 phenological stage in the corn crop; T3 = Vinasse+KCl - 50% of the dose of potassium applied via Potassium Chloride and 50% via Vinasse concentrated at the V4 phenological stage in the corn crop; T4 - Vinasse 2x 100% of the dose of potassium applied via Vinasse concentrated at the phenological stage of V4 and V8 in the corn crop; T5 = Vinasse 2x + KCl 2x - 50% of the dose of potassium applied via Potassium Chloride and 50% via Vinasse concentrated at the phenological stage of V4 and V8 in the corn crop. Thus, it is significant for plant height and number of leaves when applying vinasse in two phenological stages.
