Effect of inorganic modules on yield, nutrition composition and nutrient use effeciency in pea (Pisum sativum)

A field experiment was conducted during Rabi 2002 to 2005 to find out the effect of macro and micro nutrients on vegetable pea. Result indicated that Azad P-1 produced significantly higher yield and content of N, P and S in grain and straw (11.3 q/ha, 0.59-0.45, 2.7-3.9, and 0.42-0.37%) respectively compared to Azad P-3 and Arkel during trials. Significantly high biochemical constituents of pea seeds viz, vitamin C, reducing sugar, protein and carbohydrate 28.6mg/100gm, 3.3, 55.4 and 24.2% respectively found in Azad P-3 compared to Arkel and Azad P-1.Under inorganic modules recommended dose of NPK plus S with Mo & Fe @ 50 ppm foliar spray caused marked increased all yield and yield attributes, interaction impact on grain & fresh pod yield and biochemical constituents of Vitamin C, reducing sugar, protein and carbohydrate (11.49 q/ha76.8%and 91.4,q/ha, 89.2%,30.8 mg/100gm, 3.4%, 25.7%, and 57.3%) respectively followed by application of recommended dose NPK plus S @ 20 kg/ha and Fe @ 50ppm foliar spray. Synergetic relation between sulphur, molybdenum and iron markedly improved nutrient use efficiency and percentage return to fertilizers under foliar spray of Mo and Fe compared to other treatments.
