Abstract

New superior varieties of rice have a very important role in increasing rice production. With the widespread use of new superior varieties by farmers who are planted, more than 80% of the total rice planting area of Indonesian rice production will increase. Planting varieties that are immersion-resistant, high production and resistant to pests and diseases is an efficient way of dealing with pests and diseases and does not pollute the environment. In Jambi Province, the use of new superior varieties in irrigated land has begun to be of interest to most farmers. In Jambi Province, the use of new superior varieties of rice in irrigated rice fields has begun to be dominated by the Inpari variety. The review activities were carried out at the 2018 Constitutional Court (March-July 2018). aims to determine the appearance of several new high yielding new superior varieties of Inpari rice and to increase rice productivity in irrigated rice fields through the application of super jarwo technology. The components of super jarwo rice cultivation technology include new superior varieties with high yield potential, straw decomposers, biological fertilizers, balanced fertilization based on the Paddy Soil Test Kit (PUTS), and control of Plant Pest Organisms (OPT), as well as agricultural machinery (transplanters and combine harvester). New superior varieties consist of Inpari 1, Inpari 2, Inpari 3, Inpari 4, Inpari 12, Inpari 13, Inpari 28, Inpri 30, Inpari 32, Inpari 33 and Ciherang. The results of the study showed that the highest production was found in the Inpari 32 variety (7.2 t / ha) because it had more tillers, more filled grains, less empty grain and 1000 seeds heavier than other Inpari varieties.
