Yield component and yield performance of rice genotypes with different planting methods in dry direct seeding system

Nowadays, the rice production system faces challenges such as limited water availability, climate change, and global warming. These conditions threaten the sustainability of rice production and overall food security. To address this, rice cultivation is increasingly being directed toward more efficient water use, one approach being the use of the direct-seeded rice (DSR) method. DSR under dry conditions (aerobic system) has been proven to conserve water and contribute to rice production. However, in Indonesia, rice yields from dry DSR are still lower than those achieved using the traditional wet system. Inappropriate planting methods and unsuitable genotypes are believed to be contributing factors to the low yields. This study was designed to evaluate the variability in yield and yield components of five rice genotypes planted using two different seed-sowing methods—broadcast and drill—in a dry DSR system. The results show that the drill method produced a higher number of panicles and greater yield per hectare compared to the broadcast method, although the difference in productivity was not statistically significant. Among the genotypes, IPB193-F-17-2-3 achieved the highest productivity with the drill method, but its performance was comparable to other genotypes under the broadcast method. These findings suggest that the drill method, combined with the appropriate genotype, could serve as an alternative technology for dry DSR systems, although further development is needed to optimize results.
