Center, Exhibit Hall BC, Lower Level Brazil is currently the
fourth largest exporter and fifth largest cotton producer
worldwide, with the highest production led by the State of Mato
Grosso. The importance of cover crops has long been acknowledged
in agriculture. The use of this cultivation practice can
maintain or increase crop performance, reducing soil erosion,
increasing organic matter content, improving the physical
qualities of soil and decreasing the use of inputs like nitrogen
fertilizer and pesticides. Nitrogen application by covering and
the maintenance of straw, conducted by direct seeding, should
meet the needs of agriculture and promote soil conservation.
This study evaluates the effect of pre-sowing nitrogen
application in cotton crops and cover crops by direct seeding,
on the development and yield of cotton crop. It was conducted in
the county of Selvíria, State of Mato Gr
