Agronomic features and evaluation of forage sorghum silage as a function of nitrogen fertilisation in humid and mesothermal climate

This study aimed to determine the nitrogen application need to optimise the Forage Sorghum yield and the quality silage in regions of humid and mesothermal climate. For the agronomic evaluations of the hybrids, a completely randomised block design was adopted, while for silages evaluation, the desig...

Description
Summary:This study aimed to determine the nitrogen application need to optimise the Forage Sorghum yield and the quality silage in regions of humid and mesothermal climate. For the agronomic evaluations of the hybrids, a completely randomised block design was adopted, while for silages evaluation, the design used was completely randomised. The treatments were: 0, 50, 100, and 150 kg of N.ha −1 , with four replications each. The results showed that there was an increasing quadratic effect (P
