Abstract


A field experiment was conducted in the Viswavidyalaya Farm at Kalyani during the winter season of 1981-82 and 1982-83 to study the response of 20 (105) and HY3C varieties of pigeonpea to P2O5/ha and zinc (0, 10 and 20 kg ZnSO4/ha). Yield attributed and seed yield of pigeonpea varieties were significantly influenced by phosphorus and zinc. Application of 20 kg ZnSO4 produced significantly more height of the plant, number of pods per plant, length of the pod and yield of pigconpea. But the number of branches per plant, number of seeds per pod and 1,000 seed weight did not reach the level of significance. The response due to the application of phosphorus was quadratic in nature and optimum dose was 88.8 and 76.4 kg/ha for 20 (105) and HY3C respectively. Maximum benefit-cost ratio of 3.15 and 4.12 were obtained at 35 kg P20s/ha level for 20 (105) and HY3C varieties respectively. Variety 20 (105) yielded significantly higher over HY3C due to its higher seed number per pod and 1000 seed weight.
