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.
Shallow swamps can be used for rice production during the dry season. The problem that occurs is lack of water. The technology needed to overcome these problems is drought tolerant superior varieties. The purpose of this study is to obtain superior varieties tolerant to drought on shallow lebak swampy. The study was conducted from April 2019 to August 2019. The varieties used were Situ bagendit, Rindang 1, Rindang 2, and the Siam (local) as comparison. Data collected included: plant height, number of productive tillers, number of grains per panicle, number of filled grains per panicle, number of empty grains per panicle and production. The method used is direct observation in the field. The data obtained were compiled by tabulation and analyzed by statistical tests namely the similarity test of the middle value (t-test). The results showed that the varieties Situ Bagendit, Rindang 1, and Rindang 2 had better numbers of productive tillers, number of grains per panicle, and number of filled grains per panicle than Siam varieties. The highest production was achieved by the Situ Bagendit variety, namely 4.6 tonnes/ha. Meanwhile, the production of Rindang 2, Rindang 1, and Siam varieties were 4.4; 4.0; and 2.0 tonnes/ha.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
