Abstract

The use of soil cover plants has varied effects on crops grown in succession, depending on the cover plant used. The objective of this study was to evaluate the effect of soil cover plants from the Poaceae and Fabaceae families grown in the autumn and winter on yields of corn and soybean grown in succession. The experiment was carried out for two years and the experimental design used was randomized block design, with six replications. Both in the first year and the second, the plots consisted of the cultivation of corn or soybeans on the different biomasses of four cover crops cultivated in autumn and winter intercropped with corn. The cover crops were two Poaceae plants (black oats and brachiaria) and two Fabaceae plants (forage pea and white lupine). The production and productivity parameters of summer corn and soybean commercial crops were evaluated Cover plants of the Poaceae (black oat and brachiaria) and Fabacea (pea and white lupine) families intercropped with corn grown in autumn-winter did not affect their yield components and yield; as well as the productivity of soybeans in succession. According to the results of this work, the cultivation of black oat, brachiaria, forage pea and lupine increases the number of species that the farmer can cultivate intercropped with corn, favoring the crop rotation system in no-till.

Highlights

Corn and soybean are considered to be amongst the most important crops in the world with 1525.38 billion tons (Mendes, 2020)

Summary

Introduction

Corn and soybean are considered to be amongst the most important crops in the world with 1525.38 billion tons (Mendes, 2020). Brazil is the third largest corn producer with a production of more than 84.7 million tons (CONAB, 2015) and the second largest soybean producer at over 96.2 million tons (USDA, 2015). To increase the productivity of agricultural areas there are necessity to improve in soil. The increase in organic matter content (Giongo et al, 2011; Souza et al, 2014) and the adoption of conservation practices. These measures can reduce the impacts of conventional farming, which tend to increase soil degradation
