| Rice is an important crop for producing the staple food of the worlds population, especially in Indonesia. However, national rice production has not been able to meet food needs so rice imports are still needed. Mostly, farmers in Indonesia still use the traditional planting system, namely the Tegel planting system (TPS). New innovations are needed to increase rice production. One of the innovations is to modify the TPS which can provide higher rice yield. This new technology is called the Jajar Legowo planting system which is abbreviated Jarwo planting system (JPS). This technology can increase a higher rice production than the conventional system. The JPS has been developed in Indonesia, but until now many farmers do not know the advantages of this technology. Therefore, this review article aimed to know the advantages of the JPS in rice cultivation compared to the TPS. Based on the literature available, there are several factors that support the success of the JPS in increasing rice yield, namely rice variety, rice fields, and plant spacing. The JPS of 2:1, 3:1, and 4:1 with a plant spacing of 25 12.5 50 cm could increase crop populations per hectare by 32%, 15%, and 11.87%, respectively than TPS with a plant spacing of 25 25 cm. The advantage of the JPS is that it could inhibit weed growth in the soil surface around rice clumps. Besides, increase in crop populations per hectare attainable compared to the TPS. In the literature reviewed, JPS of the 2:1 type can give rice yield per hectare higher than the types of 3:1, 4:1, or others. Recommended plant spacing for use in JPS is 25 12.5 50 cm. Further, the review article has made a suggestion that the JPS of the 2:1 type can be applied in rice cultivation, especially in irrigated fields. 2023, Gaurav Publications. All rights reserved. |
