KOMPARASI POTENSI HASIL DARI BEBERAPA VARIETAS UNGGUL PADI SAWAH | COMPARISON OF YIELD AMONG DIFFERENT HIGH YIELDING VARIETIES OF WETLAND RICE

Inglés. New superior varieties (VUB) are a reliable technological innovation to increase rice productivity. This study aims to determine the yield potential of some lowland rice VUB. The assessment was carried out on land owned by a member of the Sumber Rejeki Farmer Group, Cintaratu Village, Lakbok District, Ciamis Regency at Dry Season II in June-September 2020. The study used a randomized complete block design (RCBD) with six varieties of treatment and was repeated ten times. The varieties tested were Inpari 32, Inpari 42, Padjadjaran, Cakrabuana, Inpari IR Nutrizinc, and Siliwangi varieties. The variables observed included the growth component, yield component, and yield component. Data were analyzed using the F test followedby the Duncan Multiple Range Test at the Q=5% level. In addition, a correlation test was conducted between the growth components, yield components, and yields. The results of the study indicated that the new superior rice varieties studied had different performance in growth, number of tillers, yield, and yield components. Inpari 42 variety produced the highest productivity, namely 6.88 ton ha-1 which was supported by the number of grains per panicle, percentage of filled grains per panicle, and percentage of empty grain per panicle which were better than other varieties. Plant height and number of grains per panicle were positively correlated with yield.

Indonesio. Varietas Unggul Baru (VUB) merupakan salah satu inovasi teknologi yang dapat diandalkan untuk meningkatkan produktivitas padi. Penelitian ini bertujuan untuk mengetahui potensi hasil beberapa VUB padi sawah. Pengkajian dilaksanakan di lahan milik anggota petani Kelompok Tani Sumber Rejeki, Desa Cintaratu, Kecamatan Lakbok, Kabupaten Ciamis pada Musim Kemarau (MK) II bulan Juni-September 2020. Kajian menggunakan Rancangan Acak Kelompok Lengkap (RAKL) dengan enam perlakuan varietas dan diulang sepuluh kali. Varietas yang diuji adalah varietas Inpari 32, Inpari 42, Padjadjaran, Cakrabuana, Inpari IR Nutrizinc, dan Siliwangi. Peubah yang diamati meliputi komponen pertumbuhan, komponen hasil, dan hasil. Data dianalisis dengan uji F dan dilanjutkan dengan uji Duncan Multiple Range Test (DMRT) pada taraf Q=5%. Selain itu dilakukan uji korelasi antara komponen pertumbuhan, komponen hasil, dan hasil. Hasil kajian menunjukkan bahwa varietas unggul baru padi yang dikaji memiliki keragaan yang berbeda pada pertumbuhan, jumlah anakan, hasil, dan komponen hasil. Varietas Inpari 42 menghasilkan produktivitas paling tinggi yaitu 6.88 ton ha-1 yang didukung oleh jumlah gabah per malai, persentase gabah isi per malai, dan persentase gabah hampa per malai yang lebih baik dibandingkan dengan varietas lain. Tinggi tanaman dan jumlah gabah per malai berkorelasi positif terhadap hasil.
