Agronomic and economic study of the application of some rice cropping systems in irrigation rice land

In response to rising population growth and the increasing demand for staple foods like rice, the Indonesian government is adopting new strategies including the Jajar Legowo planting system. This research, conducted on farmland in Jebed Utara Village, focused on two factors: five rice varieties and three planting systems. The data, collected during the dry season, was assessed in a randomized block factorial experimental design. All varieties showed potential for increased productivity using the Jajar Legowo system. The 2:1 Jajar Legowo planting system yielded the highest grain output (7.99 t ha- 1 ), marking a 15.2% increase compared to the conventional system. Additionally, it achieved the highest R/C ratio, indicating its viability as a planting system. The study suggests that adopting the Jajar Legowo planting system, particularly the 2:1 model, could significantly enhance rice production in Indonesia.
