Abstract
Rice is the second most widely grown cereal crop and staple food for more than half the world’s population. Fertilizers supply essential nutrients, mainly NPK. These fertilizers increases the yield of the crop but they cause several health hazards. To overcome that, bio-fertilizers have emerged as an important component for biological nitrogen fixation. They offer an economically attractive and ecologically route for providing nutrient to the plant. Bio-fertilizers are low-cost renewable source of nutrient that supplements the chemical fertilizers. The present study was conducted to determine the effects of bio-fertilizer on the growth and yield performance of rice variety AU1GSR cultivar. The Field experiement revealed that the treatment T5 - 75% NPK + Azospirillum + Pseudomonas fluorescens AU1 was found to be the best in promoting the growth and yield of rice followed by T1 – 100% NPK. T6 – Control were found to be perform less. The result obtained from the study indicated that the application of the bio fertilizer combination is the best for rice production as it was superior over other fertilizer combinations in terms of yield and yield attributing characters with the highest benefit cost ratio.
