This study aims to determine the performance of drip irrigation technology as compared to conventional farmer’s practice on rice growth and yield, grain quality, and water consumption. The research was carried out at the Sukamandi Experimental Station, Subang, West Java in July - October 2019. The test was arranged by a nested randomized block design with 5 replications. The main plot was water management with 2 levels: (1) Drip Irrigation Technology (DIT) and (2) Conventional Farmer’s Practice (CFP) (flooded condition) as a comparation. Subplot was varieties with 4 levels: two hybrid rice (1) Hipa 8 and (2) Hipa 18, upland rice (3) Inpago 11, and irrigated inbred rice (4) Inpari 42. The result showed that yield of DIT not significantly different to CFP with higher number of tillers per m2. However, it was lower for plant height, tillering ability, grain filling, 1000 grains weight, transpiration rate, assimilation rate and stomatal conductance. For grain quality determination, DIT gave an increase in the average of grain density and impurities, but decreased in the average percentage of chalky and immature grains. In Hipa 18, DIT was able to produce a higher percentage of head rice. DIT only consumed 3864 m3/ha/season water irrigation compared with average water consumption in Sukamandi Field Station which range of 7460-8740 m3/ha/season.Keywords: Drip irrigation, Rice, Water, Yield, Grain quality
Identifikasi ketahanan plasma nutfah padi terhadap virus kerdil bertujuan untuk mendapatkan informasi mengenai varietas dan aksesi yang tahan terhadap virus kerdil padi, yaitu Rice ragged stunt virus (RRSV) dan Rice grassy stunt virus (RGSV). Penelitian dilakukan di Rumah Kaca Balai Besar Penelitian Tanaman Padi pada MT1/MT2 tahun 2018. Materi genetik yang diuji yaitu 19 varietas padi yang sudah dilepas dan 50 aksesi plasma nutfah padi koleksi Balai Besar Penelitian Tanaman Padi Badan Litbang Pertanian-Kementerian Pertanian. Pengamatan mengikuti metode skoring SES IRRI 2014. Respons tanaman uji terhadap RRSV dapat dikelompokkan menjadi rentan (1 varietas dan 22 aksesi), agak tahan (18 varietas dan 22 aksesi), dan tahan {2 aksesi, yaitu MDK Karawang (800 butir/Malai) (10597), dan Pulo Hitam (10615}. Respons tanaman uji terhadap RGSV dapat dikelompokkan menjadi rentan (16 varietas dan 34 aksesi), agak tahan (3 varietas dan 11 aksesi), dan tahan (1 aksesi, yaitu Ketik 1-1062). Lebih lanjut, aksesi padi yang tahan terhadap RRSV dan/atau RGSV dapat digunakan sebagai tetua dalam perakitan varietas yang tahan terhadap virus kerdil.
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.
