Sustaining soil productivity by integrated plant nutrient management in wheat based cropping system under rainfed conditions

ABSTRACT

The study of the use of organic [FYM] and inorganic [NPK] nutrient sources with biofertiliser on wheat-fallow and wheat-maize cropping system under rainfed environment revealed significant increase in biometric parameters of wheat during winter and summer seasons of two years. During both the seasons, application of 1/2 NPK + 1/2 FYM + Biopower [brand] produced the highest grain yield [3684 kg/ha] and [3781 kg/ha] of wheat with the maximum N uptake of 357 kg/ha, P uptake of 51 kg/ha and K uptake of 215 kg/ha. Wheat-maize cropping system was found to be profitable economically with integrated use of mineral and organic and/or Biopower under rainfed conditions of Pakistan
