Impact of long-term integrated nutrient management on crop productivity and sustainability under cereal-vegetables-pulses cropping system in an acid upland Inceptisols

Abstract:
The long term (10 years) effect of various integrated nutrient management practices under cereal-vegetables-pulses cropping system on crop productivity and sustainability is being studied in an acid upland Inceptisols of Bhubaneswar. The results revealed that the integrated application of 100% NPK (STD) with organics (FYM/vermicompost), biofertilizers and lime resulted in higher biomass yield, maize equivalent yield (MEY), relative agronomic efficiency (RAE). The 10 years pooled data indicated that MEY response due to fertilizers was 64.8 per cent, organics 60.3 per cent, biofertilizers 14 per cent and lime 18.4 per cent. The control and sole STD treatments were not sustainable (lower SYI). However, highest SYI of 0.54 was observed in STD + VC /FYM + Lime + Biofertilizers treatment indicating sustainability of the complete integrated treatments.
