RESPONSE OF LATE SHOWN WHEAT (TRITICUM AESTIVUM) TO FYM, BIOFERTILIZERS AND INORGANIC N ALONE AND IN DIFFERENT COMBINATIONS

A field experiment was conducted on late sown wheat at C.S. Azad University of Agriculture and Technology, Kanpur (U.P.), India; during rabi season of 2008-09. The treatments consisted lone application of FYM 5 t/ha or biofertilizer (Azotobacter or Azospirilium) 5 kg/ha and their individual or combined integration with 40 kg N/ha against lone application of 40, 80 or 120 kg N/ha alongwith one control. The results revealed that integrated use of 40 kg N/ha + 5 t/ha FYM + 5 kg/ha biofertilizer (Azotobacter) produced highest grain yield of 36.29 q/ha and earned maximum net income of Rs. 24641/ha. It was followed by integration of 40 kg N/ha + 5 t/ha FYM + 5 kg/ha Azospirilium with 35.66 q/ha grain yield and Rs. 23864/ha net income and by lone application of 120 kg N/ha with 34.89 q/ha grain yield and Rs. 23173/ha net income. These 3 treatments remained significantly at per with each other. All fertility treatments produced significantly higher yield and earned more income than control treatment. It was also observed that integration of FYM or biofertilizer with 40 kg N/ha recorded yield and income at per with 80 kg N/ha. It is thus proved that application of inorganic N fertilizer may be reduced by 66.7% with integrated use of 40 kg N + 5 t FYM + 5 kg biofertilizer per hectare in late sown wheat crop.
