Resources in increasing protein yield in cultivation of soyabean on normal chernozem.

摘要

Effects of mineral fertilizers and nitrogen fixing bacterial preparations on productivity of soyabeans were studied in Rostov region, Russia in 2000-02. The treatments studied were control, N30P90, N60P90, N90P90, N60P90K60, N60P45K30; and the treatments above with addition of rizotorfin 634b bacterial fertilizer. Data on productivity and crude protein content are tabulated. The best results were obtained using seed treatment by rizotorfin 634b and N60P45K30 (productivity 2.62 t/ha, crude protein yield 1101 kg/ha).
