Abstract:

The experiment was done during kharif season 2016 at farmer field in Bhadohi district near Varanasi to ascertain the validity of developed fertilizer adjustment equations based on Soil Test Crop Response for targeted yield of this crop. These equations were compared with other fertilizer use practices such as farmer’s practice and general recommendation. Fertilizer doses for different crop under STCR based fertilizers application treatment were calculated using fertilizer adjustment equations for targeted yield of different crops. The percent increase in yield ware 17.11 and 37.79 with targeted yield 40q ha-1 and 50q ha-1, respectively over RDF. The remarkable net benefit of rice at location (Rs. 27426.00 and Rs. 37334.00) under treatments where plant nutrients applied as per soil test value (STCR treatment).The highest microbial biomass were recorded inT7 (biomass carbon 234.80 µg g-1) as compared to T1 (biomass carbon 136.61 µg g-1).The highest enzymatic activities were also recorded in T7 (urease activity 231.45µg g-1 soil hr-1) as compared to T1 (194.77µg g-1 soil hr-1) treatments. Enzymatic activities were positively and significantly correlated with content of organic carbon.Though fertilization significantly improved rice productivity over control the application of NPK and FYM in combination was found more effective in increasing rice productivity and soil nutrient status than single application of FYM or chemical fertilizer.
