Description A field experiment was conducted to study the “Performance of cowpea genotypes
during summer 2012 at different phosphorus levels” under irrigated condition in vertisols in
the farmer’s field at Mattihal Village of Basavan Bagewadi Taluk in Bijapur district. The
experiment was laid out in a factorial RCBD design with three replications comprised of 12
treatment combinations of four genotypes ( KBC-2, KM-5, IT-38956-1 and C-152) and three
phosphorus levels(25, 50 and 75 P205 kg ha-1 ).
The results indicated that seed yield (1397 kg ha-1), harvest index (0.51) and higher
grain protein content (24.25) with IT-38956-1 owing to higher number of pods per plant
(16.78) seed yield per plant (12.74 g) and 100 seed weight (12.92 g) as compared to other
genotypes
Phosphorus levels had a significant effect on growth and yield parameters.
Application of 50 kg P2O5 ha-1 recorded significantly higher seed yield (1087 kg ha-1) than 25
and 75 kg P2O5 ha-1. The higher yield was due to the higher yield parameters such as number
of pods per plant (13.17), seeds per pod (13.25), 100-seed weight (12.33 g) and seed yield per
plant (10.82 g).
Higher interaction was recorded in cowpea genotype IT-38956-1 with application of
50 kg P2O5 ha-1 for seed yield (1423 kg ha-1) , gross returns (42690 Rs. ha-1), net returns
(28493 Rs. ha-1) and B:C(3.01) ratio compared to other interactions.
