Phosphate fertilization and inoculation of soybean in vertisols
The symbiosis between rhizobia and soybean [Glycine max [L.] Merril] provides most of the nitrogen requirements of the crop through a process that also depends on the availability of nutrients, for example phosphorous. The objective of this study was to determine the contribution of P fertilization...

| 520 | |a The symbiosis between rhizobia and soybean [Glycine max [L.] Merril] provides most of the nitrogen requirements of the crop through a process that also depends on the availability of nutrients, for example phosphorous. The objective of this study was to determine the contribution of P fertilization [0, 18 y 36 kg ha-1] and Bradyrhizobium japonicum inoculation on the nodulation and grain yield of soybean crops in Vertisols with low soil P availability. In the sites without previous soybean crops, the inoculation promoted a greater nodulation, and shoot dry matter and grain yields above the non-inoculated crops. Nodulation and shoot growth increased with increasing available P [Psoil + Pfertilization] levels up to 12.4 mg kg-1. In the sites rotated with soybean, yields were greater in the inoculated crops. Shoot dry matter and grain yields increased with increasing available P levels only under inoculation. In general, the inoculated and fertilized crops showed greater production suggesting the convenience of the combined nutrition of soybean crops for achieving greater grain yields. | ||
