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.
