Abstract:
The excessive application of in soil conditioner on paddy rice not only increase the production but also give a significant effect on land degradation, environmental problems and the increasing of rice yield losses. The experiments had been conducted to investigate the effect of biofertilizer (consortia of phosphate-solubilising mircrobes and nitrogen-fixing bacteria) and soil conditioners (straw compost and charcoal husk) to increase growth and yield of paddyrice. The experiment was arranged as randomized block design (RBD) with three replications. The combination treatments consisted of biofertilizers(phosphate-solubilizing microbes (Pseudomonas mallei. P.cepacea, Penicilliumsp. and Aspergillussp, and nitrogen-fixing bacteria (Azotobactersp. and Azosprilillumsp.), which were ; without bio fertilizer; 5 L ha-1 of liquid bio fertilizer; and 50 kg ha-1 of solid biofertilizer. While the soil conditioners ,which were : without soil conditioner; straw compost; charcoal husk; and cow manure. The results of experiment revealed thatbiofertilizer and soil conditioners increased growth and yield of paddy rice.
