ABSTRACT
Rice is a food crop commodity that plays a very important role in the economic life of Indonesia. Rice production which tends to decline due to the lack of application of innovation in rice cultivation. One of the efforts that can be done is by applying the SRI (System of Rice Intensification) method. The application of the SRI method has a major problem, namely the very rapid growth of weeds. This research was carried out in the rice fields of Pasar Ambacang Village, Kuranji District, Padang City, from November 2020 to April 2021. The study aimed to obtain the interaction between the application of organic mulch on the growth and yield of three rice varieties and to obtain the best type of organic mulch for the growth and yield of three varieties of lowland rice, and to get the rice variety that gives the best growth and yield with the SRI-jajar legowo 4:1 method. This study used a factorial Completely Randomized Design (CRD). The first factor is the type of organic mulch which consists of 2 levels, namely straw mulch and reeds mulch, the second factor is the rice variety which consists of 3 varieties, namely the Batang Piaman variety, the Anak Daro variety and the IR 42 variety. Observational data were analyzed using the F 5% test. The results obtained indicated that there was an interaction between the application of organic mulch to the three varieties of rice using the SRI-Jajar Legowo 4:1 method on weed biomass, plant height, number of unhulled grains and number of pithy grains, and the best result was obtained using organic mulch of alang-alang (cogon grass) weed on the growth and the yield of the Anak Daro variety.
