Growth, Yield and Economics of Field pea (<i>Pisum sativum</i> L.) as Influenced by Phosphorus and Bio-fertilizers under Subtropical Conditions of Jammu

A field study was conducted in Rabi season of year 2009-10 at the Agronomy Farm of SKUAST-J to studygrowth, yield and economics of field pea (Pisum sativum L.) as influenced by phosphorus and bio-fertilizers under subtropical conditions of Jammu. Results revealed that among various levels of phosphorus and bio-fertilizers, 100 per cent recommended dose of phosphorus and dual inoculation of Rhizobium + PSB recorded significantly higher values of growth and yield attributes studied. Recommended dose of phosphorus recorded seed yield of 15.85 q ha(-1) with a benefit cost ratio of 1.86 than other phosphorus levels and control. Among seed inoculation treatments, dual inoculation of Rhizobium + PSB produced significantly higher seed yield of 15.01 q ha(-1) and benefit cost ratio of 1.77 than inoculation of Rhizobium and PSB alone, but significantly superior over control. The interaction effect of phosphorus and bio-fertilizers was significant on number and dry weight of root nodules and seed yield.
