Studies on character association and path analysis in groundnut (Arachis hypogaea L.)

Fusarium solani, an incitant of Fusarium root rot in coriander which causes economical yield loss and damage to coriander crop in Andhra Pradesh. The diseased plants showed poor growth and partial or fully damaged root system with conspicuous reduction in yield. To permit environment safe and to avoid dispensable use of fungicides sprays an integrated disease management trail was conducted against Fusarium root rot disease with Neemcake, Carbendazim + Mancozeb and Trichoderma harzianum in seven treatments and three replications under field conditions using direct and combined applications. Results from the present study depicts application of Neemcake @250kg/ha + Trichoderma harzianum @5kg/ha significantly showed better growth and yield paramters viz., Plant height (37.7cm), No. of. Branches/plant (4.7), No. of. Umbels/plant (6.3), No. of. Umbellets/umbel (5.0), Root length (16.5cm), Seeds/umbel (6.7) and Yield/plant (1.8g) over the control plot.
