Resumo
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.
