ABSTRACT
This study aimed to evaluate the productivity of grain sorghum submitted to organic management. Was conducted a field experiment and used a randomized block design with 32 treatments in a factorial 4x8. Were studied the effects of four quantities of cattle manure (Q1 = 0, Q2 = 2, Q3 = 4 and Q4 = 6 kg m-1 bed) and 8 doses of biofertilizer enriched (D1 = 0, D2 = 80, D3 = 160, D4 = 240, D5 = 320, D6 = 400, D7 = 480 and D8 = 560 mL/linear groove/time) in the period of growth and yield of grain sorghum. It follows that the number of seeds per panicle was positively influenced by the quantities of cattle manure and the dosages of biofertilizer, as the seed weight per panicle responded positively dosages of biofertilizer.
