Effect Of Intermittent And Conventional Irrigation On Rice Growth And Production

Abstract

Rice is a crop that has great prospects for development. Water is an important element in rice cultivation, but not all phases of rice growth require water. Intermittent irrigation system is a concept of saving water use through the regulation of water conditions in the field. The purpose of this study was to compare the growth and production of rice plants with intermittent irrigation and conventional irrigation treatments. The research method used was T-test with Diagonal Sampling Experiment Method. This experiment was conducted in Karangan Village, Karangan Subdistrict, Trenggalek Regency in December - March. The results of the experiment showed that the treatment of intermittent irrigation and conventional irrigation on rice plants gave a significantly different effect, water discharge parameters with 30,000 litres in the treatment of intermittent irrigation and 60. 000 litres in the conventional irrigation treatment, soil pH with a result of 6.7 in intermittent irrigation and 6.5 in conventional irrigation, plant height with an average of 94.8 cm in intermittent irrigation and 100.8 in conventional irrigation, number of tillers with a result of 14 tillers in intermittent irrigation treatment and 18 tillers in conventional irrigation treatment, grain weight of 1000 grains with a result of 28 grams in intermittent irrigation treatment, and 26 grams in conventional irrigation, number of panicles with a result of 11 panicles in intermittent irrigation and 12 panicles in conventional irrigation.
