Abstract: A field experiment was conducted during (2002 to 2005) at IIVR, Varanasi, to find out the effect of recommended dose of nitrogen, phosphorus potash with pressmud on vegetable pea. Result indicated that Azad P-1 variety produced significantly higher yield and nutrient balance refers in soil compared to Azad P-3 variety during trials. While biochemical constituents of pea seeds viz, protein, vitamin C, reducing sugar and carbohydrate (23.6%, 26.9 mg/100gm, 3.1% and 55.0%) was found significantly higher in Azad P-3 compared to Arkel and Azad P-1.The recommended dose of N₃₀P₆₀K₈₀ kg/ha with pressmud @ 2t/ha caused marked increased in yield and yield attributes and biochemical constituents viz protein, reducing sugar carbohydrate and nutrient contents in grain i.e. N, P and S were 25.5%, 3.9%, 57% 4.0, 0.69 and 0.45% respectively and nutrient balance in soil was found significantly higher under its combination. Whenever more content of Vitamin “C” 31.6 mg/100gm under zero level nitrogen and recommended dose of phosphorus and potash along with pressmud @ 2t/ha. This combinations (N₃₀P₆₀K₈₀ kg/ha + pressmud @ 2t/ha) markedly improved nutrient balance in soil, seed yield as well as biochemical constituents and nutritional value in vegetable pea.
