Abstract

Superior varieties are one of the technologies that play an important role in increasing the quantity and quality of agricultural products. The real contribution of superior varieties to increasing national rice production was reflected in the achievement of rice self-sufficiency in 1984. This was related to the characteristics possessed by superior varieties of rice, including high yields, resistance to major pests and diseases, early maturity so that can be developed to increase the cropping index, and taste good (fluffy) rice with relatively high protein content. The purpose of this activity is to develop seed production of new superior varieties at early maturity resulting from the innovation of the Agricultural Research and Development Agency. The source seed production development activity was carried out from October 2021 to April 2022 in irrigated rice fields, Sidomulyo Village, Belitang District, Ogan Komering Ulu Timur Regency. By using the Cakrabuana variety, White label seed class (FS) with a planting area of 5 ha. The data collected includes growth and yield performance data. The data collected were tabulated and analyzed (quantitatively). Observations of yield components carried out 1 week before harvest, showed an average plant height of 114.6 cm with the number of productive tillers of 29.2 stems/clump. While the average panicle length obtained was 27.06 cm with an average number of grain contents per panicle as many as 143.2 grains/panicle. The weight of 1000 grains of grain is 29 grams, productivity reaching 10.2 tons gkp/ha (8.5 tons gkg/ha).

Abstract

Lowland rice has a very important role in meeting national rice needs because around 90% of rice production comes from paddy fields. The aim was to determine the performance growth and production of the Inpari variety that is adaptive and high yielding in irrigated rice fields. Inpari 42 and Inpari IR Nutri Zinc are white label with comparison to Inpari 32. The need for fertilizer is 300 kg of Ponska NPK and 200 kg of Urea/ha. Observational data included: growth performance consisting of plant height, number of productive tillers, panicle length. The performance of the yield and yield components consisted of the number of grain/panicles, the number of full grain/panicles and productivity. Data were analyzed by means of equality test (t-test).  The results showed that the plant height of inpari 42 and inpari IR Nutri Zinc was relatively short while inpari 32 was classified as medium. The number of productive tillers and panicle length of inpari 42 and inpari IR nutri Zinc were not significantly different from inpari 32. The highest production of inpari 42 was 8.5 tons gkp/ha followed by inpari Ir nutri Zinc which was 7.0 tons gkp/ha better than comparison varieties.
