Abstract
Abstract. The increase in the rice planting index aims to optimize time and space, so that the cropping index can be maximized. To achieve this, the early rice ripe variety (90 - 112 days) needed as the main instrument supported by efficiency in planting and harvesting time. This activity was carried out in Rawa Medang Village, Batang Asam District, West Tanjung Jabung Regency, Jambi Province. The methodology of the activity is to replace the existing rice variety with early maturing rice varieties with cropping 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, on an area of 2.5 ha. The activity was carried out in planting season 2019/2020 with an Integrated Crop Management approach on irrigated land. The production of Inpari 30 rice was obtained in the first planting season (6.1 tons/ha), with a harvest age of 111 days. In the second planting season, Inpari 13 variety (5.9 tons/ha) was harvested at 99 days. In the third planting season, the Inpari 33 variety produced yields (5,7 tons/ha) with a harvest age of 107 days. Total production per hectare per year using Inpari 30, Inpari 13 and Inpari 33 varieties is 17.7 tons. By using high yielding varieties, early maturing has the opportunity to increase the Crop Index and productivity to close to 20 tons/ha/year.
