Assessment Role of Integrated Management of Fertilizer and Biofertilizer to Improve Corn Production and Achieve Sustainable Agriculture

Bio-fertilizers play a very significant role in improving soil fertility by fixing atmospheric nitrogen, both, in association with plant roots and without it, insoluble soil phosphates and produces plant growth substances in the soil. They are in fact being promoted to harvest the naturally available, biological system of nutrient mobilization. Chemical fertilizers are significant to succor nutrients in soil. Heavy doses of chemical fertilizers and pesticides are commonly used in order to enhance corn yields. Excessive nitrogen content in soil causes an inappropriate high uptake of this macronutrient by plants, which may result in inadequate growth and development due to the accumulation of nitrogen compounds in plant tissue. Growth prompting bacteria are including Azotobacter, Azospirillum and Pseudomonas. Azobacter, a free living and heterotrophic bacteria fixes nearly 20 to 40 kg nitrogen ha-1 and increases yield up to 50% 30. Combination fertilizer and biofertilizer also increases the rate of water and nutrient absorbance which raise the rate of growth and photosynthesis. These combination also increase the grain yield, yield components, and biological function, it has been found that bio-fertilizers can be combined with chemical fertilizers in a complementary way to reduce the excessive amount of chemical fertilizers used to grow corn. Applications of Nitroxin bio-fertilizer and chemical fertilizer (400 kg.ha-1 urea with 300 kg.ha-1 ammonium phosphate) had a significant effect on corn crop production. It seems according valid researchers consumption 150 kg Nitrogen ha-1 with 1 L.ha-1 Nitroxin led to achieve maximum corn seed yield and it can be advice to producers. Also use 50% Urea fertilizer plus Nitrokara biological fertilizer and 50% Triple Super phosphate fertilizer plus potabavar-2 could be considered by researchers and farmers.
