ABSTRACT
It is revealed from field experiment that four irrigations and seed treatment with Trichoderma viride were found
effective in reducing the disease incidence to the tune of 5.03% and 5.53%, respectively. It was followed by carbendazim
(6.27%) and Trichoderma harzianum (8.00%) over control (15.43%). Among the various interactions between different
irrigation levels and seed treatments, the interaction of four irrigations and seed treatment with T. viride were indicated
minimum disease incidence upto 2.64%. Effect of irrigation levels and seed treatments on seed germination of cowpea were found to be non-significant under different irrigation levels. The highest seed germination (90.98%) was recorded at T. viride treatment and was significantly superior over control treatment. In interaction four irrigations and seed treated with T. viride showed germination upto 91.57%. Maximum yield of seed (6.68 q ha-1) was obtained from four irrigations whereas, one irrigation recorded significantly lower yield of grains (4.24 q ha-1). Highest yield in plot treated with T. viride was obtained (6.05 q ha-1). The control treatment recorded the lowest grain yield 4.62 q ha-1. The highest grain yield 8.02 q ha-1 was recorded in the interaction between four irrigations with seed treated with T. viride. The lowest grain yield was recorded under one irrigation and control plot3.96 q ha-1.
Key words :
Cowpea, irrigation level, Macrophomina phaseolina, root rot, seed treatment.
