Improving Rice Productivity Through the Implementation of Jajar Legowo Super (Jarwo Super) Technology in Jambi Province

Abstract

Jarwo super rice cultivation is the result of the development of integrated rice cultivation technology from Indonesian Agency for Agricultural Research and Development based on the legowo row planting method. The purpose of the study was to determine the adaptation of new superior varieties of rice and increase rice production by using the Inpari 30, Inpari 32 and Inpari 33 varieties through the application of jarwo super technology. The assessment activity was carried out in Rantau Panjang Village, Batang Asai District, Sarolangun Regency, Jambi Province, cooperated with the Tanjung Harapan farmer group (involving 21 farmers) with area of 10 ha. The activity was carried out from September to December 2016. The purpose of the study was to determine the growth performance and increase in production of new superior varieties Inpari 30, Inpari 32 and Inpari 33 through the application of super jarwo technology. The components of super jarwo rice cultivation technology included new superior varieties with high yield potential, straw decomposers, biological fertilizers, balanced fertilization based on the Paddy Soil Test Tool, and control of Plant Pest Organisms with vegetable and chemical pesticides based on control thresholds, as well as agricultural machinery (transplanter and combine harvester). The results of the study showed that the innovation of super legowo row (jarwo) cultivation technology with superior varieties Inpari 30, Inpari 32 and Inpari 33 was able to increase yields by an average of 3.41 t/ha (40 - 50%), with the production of each variety was Inpari 30 (5.60 - 8.58 t/ha), Inpari 33 varieties (6.50 - 8.20 t/ha), and Inpari 32 (7.25 - 7.30 t/ha). The results were higher than the average yield of the Ciherang comparison variety (4.60 t/ha) which was commonly grown in the Rantau Panjang location. Disemination of Jarwo Super technology has been carried out through technology guidance, fields meeting, and leaflets, generally farmers can receive the introduced super jarwo technology.
