Response of pea (Pisum sativum L.) cv. 'Swastik' ('DMR 11 ') to moisture stress and application of phosphorus, sulphur and zinc fertilizers was studied during the winter season of 1992-93 and 1993-94 at the Indian Agricultural Research institute, New Delhi. Higher values of root dry weight, number and dry weight of root nodules/plant, nitrogenase activity, and growth parameters (leaf-area index, net assimilation rate, crop-growth rate, nitrate reductase activity) were observed with no moisture stress treatment, i.e. irrigation at all the 3 stages, viz. vegetative, flowering and pod filling. Application of 26.2 kg P/ha recorded higher values for root and growth parameters when compared to 13.1 kg P/ha and no P. Application of 40 kg S+5 kg Zn/ha also improved root and growth parameters, and yield of pea.
