Abstract
The effect of organic fertilizer quantity on the yield and seed qualities of Pathumthani 1 rice revealed that the highest grain yield, 3,893 kg/ha, was attained with the application of 2.24 kg N/ha of organic fertilizer, whereas rice without fertilizer exhibited the lowest yield. However, the application of 1.6 kg N/ha of organic fertilizer resulted in the highest seed germination rate, germination index, and pure seed percentage, with values of 98.00%, 32.43, and 99.71%, respectively. Conversely, applying 2.24 kg N/ha of organic fertilizer yielded the lowest seed germination rate, germination index, and pure seed percentage at 87.50%, 28.74, and 98.11%, respectively. Moreover, the 1.6 kg N/ha rate demonstrated the least inert matter and the lowest number of dead seeds. Consequently, the findings suggested that organic fertilizer should be applied at a rate of 2.24 kg N/ha to achieve high grain yields, while it is still maintained seed germination percentage of over 80%.
