The Impact of Employing Microbacter Alfaafa – 11 (MA-11) and Organic Fertilizer on the Quantity and Quality of Rice Resulting from the Crossing of Sigupai and IRBB27

Abstract

The objective of this study is to assess the impact of employing Microbacter Alfaafa-11 MA-11 and organic fertilizer on the yield and quality of the F9 rice variety resulting from the crossbreeding of sigupai with IRBB27. The research was conducted at the Saree State Vocational School-PP located in the Lembah Seulawah District of Aceh Besar Regency. The physical and chemical parameters of rice were analyzed at the Seed Science and Technology Laboratory and Plant Physiology Laboratory, Faculty of Agriculture, Syiah Kuala University, between February 2023 and August 2023. This study employed a factorial Randomized Group Design (RAK) with 12 treatment combinations. Each treatment had 3 replications, and each replication consisted of 3 pots. Therefore, there were a total of 36 experimental units. The variables in this study include the initial factor: the concentration treatment of Microbacter Alfaafa-11 (MA-11) (A), which is divided into 4 levels: A0 (with no MA-11), A1 (0.05 ml MA-11 per 2.50 ml water), A2 (0.1 ml MA-11 per 2.50 ml water), A3 (0.15 ml MA-11 per 2.50 ml water). The second factor is the application of organic fertilizer treatment, which includes two components: Super Bokashi Fertilizer dose and Biofarm concentration. This factor is divided into three levels: B1 Super Bokashi (10 t ha-1), B2 Biofarm (14-liter ha-1), and B3 Super Bokashi + Biofarm (10 t ha-1 + 14-liter ha-1). The observation criteria include agronomic factors such as harvest age, as well as rice quality tests that assess physical features such as yield rice, milled rice, rice dimensions, and chemical attributes such as water content and protein content. The findings indicated that the use of Microbacter Alfaafa-11 MA-11 and organic fertilizer did not have any notable impact on the harvest age and rice quality parameters of the F9 line resulting from the crossbreeding of sigupai with IRBB27. The maximum rice yield achieved a percentage of 74.98%, with the average being slender rice. The water content ranged from 14.00% to 15.80%, while the highest protein level reached 6.93.
