Influence of Path-Rows and Direct Seeded System on Productivity of Rice (Oryza sativa l.)

ABSTRACT

Rice is one of the staple foods in Indonesia that recently its production still has quite a lot of problems, including limited land, low soil fertility, and declining crop productivity. The experiment of path-rows planting system and direct seeded was conducted to find out the productivity level of rice plant with different planting systems. The design of experiment used on-farm research design by making observations on the specified variable. The experiment of path-rows planting system and direct seeded system was done in district Mojolaban, Sukoharjo Regency. On the system, plants are grown using path-rows in 2:1 line model, square size 2.5 x 2.5 meter, plant spacing at 20 x 10 cm. Whereas, on the system of the crop planted, direct seeded with a distance of 20 x 20 cm. Samples were taken randomly (5 plants) and replicated 3 times. The variable observed includes plant height, number of tillers, dry grain yield, and dry weight of the milled grain. The data are analyzed using One Way Anova test. The results showed that path-rows planting system can increase dry weight of the milled grain 45% and the dry weight of the harvest grain by 10%, while the direct seeded system increased rice productivity by 15% than the conventional cropping system.
