Physical segregation of seed mixtures between marandu grass and NPK fertilizer in a jab-planter- seeding simulation
Abstract
Mixing Brachiaria brizantha seeds with NPK fertilizer is a practice that has been used in the renovation of pastures and implementation of the agriculture-livestock farming integration system. Therefore, the objective of this study was to evaluate the physical segregation in the B. brizantha seed mixture with NPK fertilizer by simulating seeding with a jab-planter. A random block design with four replicates was used. Treatments consisted of B. brizantha seeds mixed with NPK fertilizer (10-28-20 rate) and the jab-planter container filled to 80, 40, or 20% of its capacity. The density of the mixture components was determined and 3 subsamples were collected for each treatment during the seeding simulation to determine the weight of each component. No significant differences were observed for any of the variables. Therefore, B. brizantha seeding can be performed by mixing the seeds with NPK fertilizer using a jab-planter, without the occurrence of segregation of mixture components.
