Keragaan Agronomi Padi Varietas Inpari Di Sawah Irigasi Kabupaten OKU Timur Sumatera Selatan

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.
