A field experiment was conducted at New Delhi during 1992-94 to study the growth and yield responses of pea (Pisum sativum L.) cv. Swastik (DMR 11) to moisture stress and application of phosphorus, sulphur and zinc. The moisture stress at flowering appeared to be most critical in influencing the yield of pea. Higher values of vine length, leaf area index, dry matter, yield attributes, grain and straw yields, harvest index, nutrient uptake (N, P, K and Zn) and consumptive water use were noticed with no moisture stress treatment. Application of 26.2 kg Plha resulted in marked improvement in growth and yield attributes and yield, nutrient uptake (N, P, K and Zn), consumptive water use, water use efficiency, and soil available P at harvest. The soil available N showed improvement up to 13.1 kg Plha only. Combined application of 40 kg S + 5 kg Znl ha showed marked improvement in growth and yield attributes, grain and straw yields, nutrient uptake (P, K and Zn), consumptive water use and water use efficiency. The differences between 40 kg Slha and 40 kg S + 5 kg Znlha were not marked in S uptake in both the seasons, and N uptake in 1993-94.References
