EFFECT OF LONGTERM MANURIAL ADDITION ON THE YIELD OF CROPS AND NUTRIENT AVAILABILITY UNDER RAINFED VERTISOL

Abstract

Field experiments were conducted during the rabi seasons of 1991-1992 to 1994-1995 in Vertisol to study the effect of continuous addition of organic and inorganic fertilisers on the yield of crops and nutrient availability. The application of recommended level of N (40 Kg/ha) 50% as urea and 50% as FYM registered the maximum grain and straw yield besides improving the soil fertility status.

Keywords: Longterm effect, yield, organic and inorganic fertilisers
