Abstract

The objective of this study was to evaluate the effect of growth regulator and Trichoderma harzianum in common bean, in succession to different cover crops. The experimental design consisted of split-plots, in randomized complete blocks, with four replications. For plots, the leguminous Cajanus cajan, Stylosanthes guianensis, and Crotalaria spectabilis, and the grasses Pennisetum glaucum, Panicum maximum, Brachiaria brizantha, B. brizantha associated with Zea mays, and Sorghum bicolor were used as cover crops. The subplot treatments were: control; 500 mL of growth regulator (GR); 1,250 mL of biological fungicide (BF); and 500 mL of GR plus 1,250 mL of BF, in 100 kg of seeds. Eighty-four days after the cover crops cutting, the common bean cultivar BRS Valente was sown. The root rot severity caused by Rhizoctonia solani and Fusarium solani f. sp. Phaseoli, incidence of fusarium wilt, grain yield, one hundred grain weight, number of pods per plant, and number of grains per pod were evaluated for common bean. The treatments with biological fungicide and growth regulators applied via seeds did not show significant effect, in relation to the analyzed variables. The sorghum straw favored the increase of root rot severity and fusarium wilt in the common bean crop.
