Increasing the rice planting index through superior varieties of early maturity rice on the irrigated land In Jambi Province

Abstract

Abstract The increase in the rice planting index aims to optimize time and space, so that the planting index can be maximized. This activity was carried out in Rawa Medang Village, Batang Asam District, West Tanjung Jabung Regency, Jambi Province. The methodology of its activities is to replace the existing ripe variety with early-maturing rice varieties with planting patterns in the growing season: (Planting Season (PS) I: November - March) Inpari 30 variety, (PS II: March - July) Inpari 13 variety, and (PS III: July -November) Inpari 33 variety. This activity was carried out in the 2019/2020 planting season with an Integrated Crop Management approach on irrigated land. Inpari 30 rice production was obtained in the first growing season (6.1 tons/ha), with a harvest life of 111 days. In the second growing season, Inpari 13 variety (5.9 tons/ha) is harvested at 99 days. In the third growing season, Inpari 33 variety produces a yield (5.7 tons/ha) with a harvest life of 107 days. The total production per hectare per year using the Inpari 30, Inpari 13 and Inpari 33 varieties amounted to 17.7 tons. By using high-yielding varieties, it has the opportunity to increase the cropping index and productivity to close to 20 tons /ha/year.
