Soybean yield in grain production systems with annual winter and summer pastures under no-tillage
Abstract
The objective of th is study was to determine soybean plant height and yield, during a eigth-year period, in production systems of grain crops and annual winter and summerpastures. Six production systems were evaluated: system I (wheat/soybean, black oat + common vetch pasture/com); system II (wheat/soybean, black oat + common vetch + ryegrass pasture/com); system III (wheat/soybean, black oat + common vetch pasture/pearl millet pasture); system IV (wheat/soybean, black oat 4 common vetch + ryegrass pasture/pearl millet pasture); system V (wheat/ soybean, white oat/soybean, and black oat + common vetch pasture/pearl millet pasture); and system VI (wheat/ soybean, white oat/soybean, and black oat + common vetch + ryegrass pasture/pearl millet pasture). Treatments were randomly distributed in blocks and replicated four times. Soybean presented higher yield after wheat, in the systems VI, V, IV, I, 111, and II, than after white oat. Nevertheless, soybean yield, in the three last systems, was not different from the yield of soybean cultivated after white oat, in system V. Soybean after white oat, in system VI, did not differ from soybean after wheat, in system II.
