Abstract

The experiment was conducted at instructional farm of the Rajasthan College of Agriculture, Udaipur, Rajasthan to study the effect of integrated nutrient management on growth, productivity and economics of maize (Zea mays L.) variety PEHM 2. The crop produced significantly higher number and weight/cob of grains, test weight and grain and stover yields with conjoin application of recommended dose of NPK + 10 t FYM/ha com- pared to either inorganic fertilizer alone or organic sources or 50% of recommended dose of inorganic fertilizers. Application of recommended dose of NPK along with seed inoculation of Azotobacter resulted in higher net returns and B:C ratio of maize crop.
