Growth and nutrition in plants

In Brazil, there are relatively few papers about soybean crop in succession of pasture to steer performance. This work aimed to study changes in yield and yield components of soybean in succession in crop-livestock production systems, under no-tillage, were assessed in Coxilha, State of Rio Grande do Sul, Brazil, during ten years. Six crop-livestock production systems were studied: system I - wheat/soybean, and common vetch/corn; system II - wheat/soybean, and black oat pasture/corn; system III - wheat/soybean, and black oat pasture/soybean; system IV - wheat/soybean, and field pea/corn; system V - wheat/soybean, common vetch/soybean, and triticale double purpose/soybean; and system VI - wheat/soybean, white oat double purpose/soybean, and double wheat purpose/soybean. The treatments were arranged in a completely randomized block design, with four replications. In the year, no differences were found between grain yields, weight of 1,000 kernels, plant height and insertion first legumes height of soybean in crop-livestock production systems. The soybean cultivated in succession after common vetch showed higher number of pods, number of grains and weight of grain per plant than the other crop systems.
