Minapadi-Sri Pattern on Rice Cultivation with IR42 Varieties

Food needs of Indonesia's population is still dominated by rice. Meanwhile, the conversion of irrigated rice fields seems unstoppable. This fact should be addressed by policy and the application of technology for rice production so that it is still possible to meet the national food need while increasing the income of rice farmers. The experiment on Minapadi-SRI pattern of rice cultivation with variety IR42 conducted. SRI (the system of rice intensification) is the formation of phyllochron 12 times and many phytomers. The experiment was conducted from April to September 2017 at Sungai Bangek village, Balai Gadang, Koto Tangah, Padang, West Sumatera. The objective of the study was to get the best technology for food production which is profitable. A Randomized Block Design with split plots was used with two water levels (20 cm and 10 cm) and three trench widths (50 cm, 75 cm and 100 cm). Data were analyzed using the F test at the 5% level and the Honest Significant Difference test at the 5% level. Observation of the yield and yield components of rice crops; height of plants, number of tiller/clump, number of productive tiller/clump, panicle length, number of grains/panicle, number of pithy rice/panicles, weight of 1000 grains, and yield/plot were made. The result of this research is that 10 cm inundation with 50cm wide trenches are better for rice plant growth and yield/plot.
