Improving rice productivity through the new superior varieties of rice in the irrigation land, Jambi Province

Abstract

New superior varieties of rice have a very important role in improving rice productivity. In Jambi Province, the use of VUB in irrigation land has begun to be in demand by farmers and dominated by Inpari varieties. This activity aims to find out the appearance of several new superior varieties (VUB) of rice and rice productivity on irrigated rice fields. The assessment activity was conducted in Sri Agung Village, Batang Asam District, Tanjung Jabung Barat, Jambi Province from March to July 2019. New superior varieties of rice paddy planted consist of Inpari 12, Inpari 13, Inpari 30, Inpari 32, Inpari 33, Baroma, Inpari Nutri Zinc, and Ciherang on an area of 2 ha. This assessment is carried out through an integrated crop management approach (IPM) with technology components including new superior varieties, legowo jajar planting system, fertilization, disease pest control, harvesting, and post-harvest. The results showed that the highest production is found in the Inpari 30 variety which is 7.30 t/ha because it has more tillers, more grain content, fewer quantities of hollow grain and weighs 1000 seeds heavier than other Inpari varieties.
