Abstract:
The present field experiment was conducted at pot house of department of faculty of Agricultural sciences & allied industries of Rama University Kanpur under the Central Plain zone of Uttar Pradesh, during Rabi season. A study was conducted to assess fertilizer effect on wheat yield and soil fertility with the following treatments; T₁-Control,T₂–RDF (120:60:40 kg per ha),T₃-RDF+5 kg ZnSO₄ per ha,T₄-RDF+10 kg ZnSO₄ per ha,T₅-RDF+Seed treatment (ZSB),T₆-RDF+ZnSO₄ per ha + seed treatment (ZSB),T₇-RDF + 10 kg ZnSO₄ per ha + seed treatment PSB).Treatments differed significantly in influencing soil fertility and grain and straw yields of wheat crop. The study indicated that addition of 100% ZnSo₄+ZSB+Seed treatment + RDF recorded significantly higher value of growth and yield attributes in terms of plant height (cm), dry matter accumulation (g m-2),number of effective tillers (m-2) and yield attributes character grains spike-1, 1000-grain weight (g), harvest index (%), grain yield (38.40 q ha-1) straw yield (63.3 q ha-1).The content of organic carbon increase with the combined application of organic and inorganic with biofertilizer. Integration of 100% NPK + FYM + ZnSo₄ + Mn + Fe was found more productivity and remunerative with the higher residual soil fertility status after wheat crop. The highest bioavailable Zn was calculated for foliar (30%) and soil application (28%).
