Abstract:
The objectives of this research are to study the efficiency and to improve the productivity of Pathumthani 80 seeded rice with RMUTT fungal pellets and organic soil amendment Kie-dad salt. Experiments were carried out with 6 treatments, each of which used different rice growing products: in treatment 1, control treatment, no product was used; in treatment 2 organic fertilizer was added; in treatment 3, organic soil amendment Kie-dad salt was added; in treatment 4, RMUTT fungal pellets were added; in treatment 5, urea fertilizers were added, and in treatment 6, RMUTT fungal pellets and organic soil amendment Kie-dad salt were added. After 110-day growing, the rice produce was studied in terms of height, root length, growing, fresh weight, dry weight and productivity.
It was found that treatment 6 in applying RMUTT fungal pellets and organic soil amendment Kie-dad salt resulted in the highest yield of 1515.2 kg/rai whereas the yields of treatments 5, 3, 4, 2, and 1 were 1,298.4; 1,076; 1,020; 9,488; and 560.4 kg/rai, respectively. It was also found that the height, root length, growing, the fresh weight and the dry weight of rice from treatment 6 were the best. Concerning the comparison of the averages of all treatments and treatment 1, it was found that the differences were statistically significant at the 0.05 level.
From the study, it can be concluded that seeded rice growing with RMUTT fungal pellets and organic soil amendment Kie-dad salt, helps increase higher rice productivity than growing with chemical fertilizers. This would be of great benefits for rice farmers in the future.
