Integrated nutient supply systen for 'DPP 68'vegetable pea (Pisum sativum var arvense) in dry temperate zone of Himachal Pradesh

Abstract

A fleld experiment was conducted on 'DPP 68' vegetable pea (Pisum salivum L. var arvense Poir) during summer 1995 and 1996 in the cold desert soils. dry temperate zone of Himachal Pradesh to study the effect of NPK fertilization with and without farmyard manure on the productivity. yield attributes. uptake of nutrients. organic carbon content of the soil and available nutrients (N. P and K). Fertilization with NPK alone increased all these characters. The superimposition of farmyard manure in combination with chemical sources had a very significant effect. The treatment receiving 75% of the recommended dose of NPK (N₁₅ P₄₅ K_{22 5}) both in the presence and absence of farmyard manure were found to be the most suitable treatment combinations, giving higher green pod yield besides saving 25% of NPK fertilizers.
