Abstract

Rice as a staple food is still difficult to replace with other sources of carbohydrates. The problem formulation of this study was to find out how the effect of HSP and SP-36 on the production and quality of the basic seed of rice variety IR 64. This study aimed to determine the effect of HSP and SP-36 on the production and quality of the basic seed of rice variety IR 64. This study used Factorial Randomized Block Design. The first factor was the provision of HSP (A) with 3 treatment levels and the second factor was the provision of SP-36 (P) fertilizer with 3 treatment levels. Each treatment was repeated 3 times, so there were 27 experimental units. The results obtained were then analysis using Analysis of Variance. The results of the treatment which showed a real or significant difference were then carried out a follow-up test using the Duncan's Multiple Range Test with a level of 5%. The HSP treatment at a dose of 100 kg/ha showed a significant effect on the parameters of plant height aged 60 DAP (91.33 cm), the weight of dry grain per plot (2.63 kg), and the HSP treatment at a dose of 50 kg/ha showed a percentage value highest germination rate (90.41%) and growth speed of 13.65%. While the HSP treatment at a dose of 100 kg/ha had a very significant effect on the parameter number of tillers aged 60 DAP (33.78 tillers), production per hectare (11.71 tons) and at a dose of 50 kg/ha on the parameter number of productive tillers (25 .27 tillers) of rice (Oryza sativa L.) Variety IR 64. The SP-36 treatment at a dose of 200 kg/ha showed a significant effect on the parameters of the number of grain per panicle (129.59 grains) and the number of rice grain per panicle (107. 80 heads) of rice (Oryza sativa L.) Variety IR 64. The interaction between HSP and SP-36 fertilizer on rice (Oryza sativa L.) Variety IR 64 had no significant effect on all parameters. Furthermore, parameters that show significant or very significant differences are carried out by the DMRT test with a level of 5%.
