Loss sampling methods for soybean mechanical harvest

Biosci. j. (Online); 38 (), 2022
Harvesting is one of the most important stages of the agricultural production process. However, the lack of monitoring during this operation and the absence of efficient methodologies to quantify losses have contributed to the decline in the quality of the operation. The objective of this study was to mo...

Crop succession and its reflections on soybean performance

Biosci. j. (Online); 38 (), 2022
The fluctuations in yield and consequently in production occurred due to climatic adversities in the main producing states of Brazil. Farming has changed over time, and past scenarios have shown high exploitation of natural resources focusing on soil tillage and conventional seeding methods. This study a...

Combined effect of corn in the barrier crop and plant extracts against Cowpea mild mottle virus infecting soybean [Glycine max (L. ) Merr. ] in the field

Biosci. j. (Online); 38 (), 2022
Cowpea mild mottle virus (CpMMV) is one of the problems that can decrease soybean production. The research was conducted on the combined effects of corn in the barrier crop with plant extracts against CpMMV infecting soybean in the field. The field data was conducted using a Completely Randomized Design....
