A field experiment was conducted during rabi seasons for two years at Agronomy Research farm, CCS HAU, Hissar to evaluate the effect of agrispon and fertonic on yield attributes and yield of wheat. Effective tillers, earhead length, spikelets earhead-1 , grains earhead-1 , grain and straw yield of wheat enhanced significantly with 120+60 Kg ha-1 N and P( 100% of recommended dose). Fertilizer level failed to influence harvest index and test weight. Two spray of agrispon significantly @ 1 l ha-1 two application each at sowing and at 30 DAS enhanced effective tillers, spike length, spikelets spike-1 , grains spike-1 , grain, straw and biological yield over its one spray and control. Fertilizer use efficiency also increased with agrispon spray by 100% compared to the control (16.6 kg grain per kg nutrient). Fertonic remain at par with control in all parameters.
