The Growth and productivity enhancement of rice by jajar legowo (double row) planting method in freshwater swampland

Abstract

One of the technological innovations to increase rice productivity is the Jajar Legowo (double row) planting method. The research aimed to examine the technology of planting Jajar Legowo rice in two ways: manual and transplanter machines in freshwater rice fields. The research was conducted on 6 ha of freshwater rice fields in Martapura Barat, Banjar Regency and involved six cooperator farmers. The superior varieties used were Inpari-30 and Inpari-32. The results show that the average grain yield was higher with transplanter (8.10 t ha−1 GKP), compared to manual planting (6.90 t ha−1). Grain yields planted with transplanter + manure increased grain yields by 1.2 t ha−1 (increased by 17.4%). The transplanter treatment provided an income of IDR20,401,500.- and R C−1 = 2.70 higher than manual row planting (income IDR16,959,500.- R C−1 = 2.59). Transplanters also reduce labour costs for planting (IDR750, 000.- per hectare), and reduce planting times.

Growth and production of superior rice varieties in freshwater swampland at the Alabio Polder, Hulu Sungai Utara

“…Benefit cost ratio (BC -1 ) in DS 2013 and DS 2014: 2.09 and 1.78 (Table 5). The research [30] also shows that planting jajar legowo in the Lebak land of Banjar Regency provides a profit of up to Rp. 16,959,500.-and RC -1 2.59.…”

“…The new superior varieties of rice like Inpari-1, Inpari-17 dan Inpari-30 can increase the productivity and income of farmers at Teluk Cati Village. In 2013 n 2014, the yield of inpari varieties (1,17,19,30) were higher than ciherang, average yield 5,91 t/ha. Rice farming on freshwater swampland is profitable (RC -1 3.09 and 2.78) and feasible (BC -1 2.09 and 1.78).…”

Land Suitability and Upland Rice Productivity with Integrated Crop Management in Sorong Regency

“…This indicates that soybean ICM is feasible to replace soybean farming patterns developed by farmers because the MBCR value is >2. If the MBCR value is 2, then the farm is feasible and interesting to develop [12]…”
