EFICIÊNCIA AGRONÔMICA DE UM RESÍDUO BASÁLTICO UTILIZADO ISOLADAMENTE E ASSOCIADO AO ESTERCO BOVINO NA CULTURA DA PIMENTA MALAGUETA (capsicum frutescens)

Abstract

Introduction: Vegetables are food that stand out the most in the scientific literature, especially when related to contamination with pesticides. This is the reason for the increased demand for organic products. Therefore, there is a need to develop methods that enable these systems to serve the consumer and improve the income of farmers, in general, in the activity of family farming. The production of vegetables by organic system requires procedures that respect ecological processes, promoting the increase of organic matter in the soil and saving energy. Objectives: Considering the above, this paper aimed to evaluate the rock dust effect with and without the addition of organic compost from bovine manure on the chili pepper yield. Methodology: the experiment was carried out in the field of the Goiano Federal Institute, Morrinhos campus, Goiás State (GO), Brazil, from February to December 2018. The experiments were in randomized block design, ten treatments, four replicates, each one with concentrations of mica schist rock dust and different bovine manure. Results: It was found that the higher the content of rock dust and bovine fertilizer, the greater the plant yield, in relation to control treatment, allowing reliable inferences about the studied parameters and the significant influence of the increasing proportions of rock dust used, matching the hypothesis of this study. The effect of bovine manure proved to be efficient for yield variables, evidencing that the use of mica schist rock dust associated with bovine manure was efficient in the T10 treatment (400 g.m2 of rock dust + 4 kg of bovine manure) in relation to T0 (control - without addition of fertilization) and T1 (control - conventional fertilization - 12 g.m2 of urea and 16 g.m2 of potassium chloride). Conclusion: The use of mica schist rock dust associated with bovine manure guaranteed the best conditions for the development of chili peppers.
