Composting Enriched with Phosphate in Pepper Culture in Organic Production System in Vase

Abstract

This work aimed to evaluate the use of elephantgrass biomass with cattle manure, with sources of phosphorus allowed in Brazilian legislation for organic systems. Composting was carried out at the Laboratory of Organic Fertilizers of UFG. The treatments used consisted in the application of phosphates to enrich the compound in 1% of P205. The controls were: T0-Witness (without phosphate); TA (Arraias Natural Phosphate); TB (Bonito Natural Phosphate); TM (Reactive Phosphate from Morocco); TY (Yorin Thermophosphate); 20L bioreactors were used. The measurement was made in a ratio of 3: 1 on a moist volume basis (elephantgrass / manure). After composting, 20Mg / ha of pepper (10Mg / ha) and 10Mg / ha were applied at 20 days after planting. They were measured as plant heights and pepper yield. The results indicated that the improvement of the nutrient with Phosphate of Bonito and Phosphate were those that provided increases in productivity and height of plant
