Abstract
High yield varieties with pests and disease resistance and environmental stress is one of the important technological components for increasing farmer productivity and income.. This research was conducted in irrigated rice fields in Kebakramat District, Karanganyar Regency at planting season (PS) II (March-July) and PS III (July-November). The purpose of this study was to determine the growth performance and productivity of high-yield varieties of rice. The completely randomized design was used with 3 treatments 5 times repeated. Code, Winongo were used and IR 64 as a comparison. Phonska 300 kg/ha and Urea 250 kg/ha were used in this study. Data of plant height, number of tillers, panicle length, and production were collected. Data plant growth and grain yield were analyzed using variance analysis. The results showed that high-yield varieties affected increasing production. The highest rice productivity obtained from the Code reached 8.44 t / ha DMG at PS 3 or 18.2% higher than the existing IR 64, while Winongo reached 8.05 t/ha DMG or 12.7% higher from IR 64. Code has the highest production, however, Winongo at PS 3 can also be used as a choice as a substitute for IR 64 besides Code in Karanganyar Regency.
Highlights
Rice is a staple food for Indonesian and the majority of the Indonesian population (95%) are consuming rice as a daily staple food [1]
Rice production can been hanced through increasing productivity by improving the application of technology components and packages of pre-harvest, harvest and post-harvest technologies.Rice is the main commodity in Indonesia which plays an important role in supporting food security
It was different at the age of 45 DAP with a plant height range of 72.8 - 83.3 cm, between varieties, showed significant differences in both planting season (PS)- 2 and PS-3, but each variety was not significantly different between PS- 2 and PS- 3. age 45 DAP,Winongo grown on PS 2 was different from that grown on PS 3 (Table 1)
Summary
Rice is a staple food for Indonesian and the majority of the Indonesian population (95%) are consuming rice as a daily staple food [1]. The need for staple food (rice) is highly influenced by the factor of food availability which is closely related to the number population and consumption patterns.the issue of rice will remain a very strategic for agricultural sector economically, socially and politically. Rice production can been hanced through increasing productivity by improving the application of technology components and packages of pre-harvest, harvest and post-harvest technologies.Rice is the main commodity in Indonesia which plays an important role in supporting food security. The growing population in Indonesia has the potential to increase the amount of food demand, especially rice, which causes the average consumption rate of rice increase. Sustainable management of integrated rice production systems can increase awareness and understanding of the potential, flow and demand for rice needs [2].
