Present investigation was conducted on vegetable pea cv. 'Arkel' by applying five levels phosphorus viz., 0,15,30,45 and 60 kg/ha through Mussoorie Rock Phos along with nitrogen @ 25 kg/ha, Diammonium Phosphate along with and without potassium @ 25 kg/ha and Single Super Phosphate and five levels of nitrogen viz., 0,25,50,75 and 100 kg/ha through urea. Results indicated that application of 60 kg P/ha through all the sources gave maximum pod yield per hectare. However, DAP appeared as the best source of supplementing phosphorus as it resulted in highest pod yield at 60 kg P/ha (119.26 q/ha). The response of the crop to lower levels of P applied through all three sources was more obvious which was decreased down beyond 30 kg/ha and appeared as uneconomical beyond 45 kg/ha. An additional application of K @ 25 kg/ha with lower doses of P viz., 15 and 30 kg/ha and N@25 kg/ha with higher levels of P viz., 45 and 60 kg/ha had favourable effects on the pod yield. Nitrogen doses exhibited non-significant differences on pod yield and application of 25 kg/ha nitrogen was appropriate. Therefore, 25 kg N/ha+45-60 kg P/ha and 15-30 kg P/ha+25 kg K/ha was found to be economical for pod yield in vegetable pea under rainfed mid hills.
