Author(s): Samanyita Mohanty and GH Santra
Abstract: A field experiment was conducted during 2016-17 in Alfisols of Odisha to monitor the effects of different sources of phosphorus and its combination on productivity and nutrient uptake by maize-groundnut cropping sequence. Low Grade Rock phosphate (RP) and its various combination with SSP were used as nutrient sources during Kharif 2016 (Maize crop) and Rabi 2016-17 (Groundnut crop). The study comprised of eight treatments with lone sources of RP and SSP along with their different combinations, replicated thrice and they were evaluated for their effectiveness in the cropping system. Better performance of rock phosphate in combination with SSP at various proportions was observed as compared to lone rock phosphate or SSP sources. The combination significantly influenced the yield attributes and nutrient uptake of both maize and groundnut crops. Among the combination, equal proportion mixture of soluble (SSP) and insoluble (RP) source of P outreached the other combination ratios. The performance of the treatment which received lime along with water soluble P source proved to be best under acidic soil condition.
