Use of Compost bedded pack barn in maize fertilization for silage

Abstract

This article aims to study the effect of different time intervals for bed maturation in compost sheds for dairy cattle, such as organic manure in maize crop for silage. The experimental design was a randomized block in split-plot with five treatments, six collection times, and five replicates. The data were submitted to variance analysis and compared by Scott-Knott. Sigmoid functions of logistic growth were adjusted to the data. The treatments with addition of fresh and mature compost with nitrogen cover showed higher hoot dry matter production when compared to treatments without compost. For maize plant height, stalk diameter and number of leaves, it was observed that from 35 days after plant germination, these variables were considered superior for the treatments that received bedding. The sigmoid function was proper to represent the plant growth to the silage point. It is concluded that the use of bedding from compost sheds as an organic manure is recommended as a sustainable alternative in the reuse of waste from milk production.
