Evolution of crop yields in different tillage and cropping systems over two decades in southern Brazil. In the last three decades, the no-tillage system (NT) has provided environmental and economic advantages for farming in southern Brazil, especially when associated with crop rotation. The objective of... ... Repositório: BDPA Ano de publicação: 2012
Optimal plant density and nitrogen rates for improving off-season corn yields in Brazil. Integrating plant density and nitrogen (N) management is a strategy for improving corn yields, especially for off-season corn production in the tropics. This study tested the hypothesis that increasin... ... Repositório: BDPA Ano de publicação: 2019
