The effect of different rate of biofertilizer on the growth performance and yield of rice

Abstract

Rice (Oryza sativa L.) is an important cereal in the world and can be grown in different habitats such as lowland, irrigated and upland rice. In order to study the effects of biofertilizer on the growth performance and yield of rice, the experiment was carried out using Complete Randomized Design (CRD) based on 5 treatments with 5 replications. The control treatment (T0) was 100% of NPK fertilizer, treatment 1 (T1) was 30% biofertilizer and 70% NPK fertilizer, treatment 2 (T2) was 50% biofertilizer and 50% NPK fertilizer, treatment 3 (T3) was 70% biofertilizer and 30% NPK and treatment 4 (T4) was 100% biofertilizer. The rice variety used was MR 220 and different doses of biofertilizer were applied 4 times. Each of the application was mixed with inorganic fertilizer NPK at a recommended rate. The parameters used in this study were number of leaves, number of tillers, number of panicles, height of rice, 1000-grain weight and fresh weight. In this experiment, treatment 2 (50% biofertilizer and 50% NPK) showed positive result for all parameters and has significant difference between the treatments. Treatment 3 (70% biofertilizer and 30% NPK) showed the lowest means for most of the parameters. Thus, from this study, the combination of 50% biofertilizer with 50% chemical fertilizer is proved to boost a better growth and yield of rice.
