The agronomic performance and feasibility study of new high yield rice varieties in Tegal district

Abstract

Variety is one of innovations that could contribute to the increase of rice production. The objectives of this study were to compare the agronomic performance of rice varieties and its feasibility of new high yield varieties namely Inpari 30, Inpari 32 and Inpari 33) with the existing variety (Mekongga). Research was conducted in Banjaranyar Village, Balapulang Subdistrict, Tegal Regency. The agronomic performance observed were the height of plants, number of productive tillers, length of panicles, number of grain/panicles, and yield or milled dry grain production. Meanwhile the feasibility study was calcutaed in term of Revenue Cost Ratio (R/C) analysis. Result showed the significant different in observed performance among varieties. The productivity of Inpari 30, Inpari 32 and Inpari 33 were 5.45, 5.97, and 5.89 tons/ha of milled dry grain (GKG) respectively. All new high yield varieties showed better production performance compared to Mekongga (4.96 tons/ha GKG). The feasibility study showed R/C value of Inpari 30, Inpari 32, Inpari 33 and Mekongga were 1.28, 1.41, 1.39 and 1.14, respectively. Among these varieties, Inpari 32 has the highest feasibility study value.

Agronomic and economic study of the application of some rice cropping systems in irrigation rice land

“…Is done to determine the feasibility of rice farming in three planting systems, as an alternative for farmers to develop. The feasibility of farming was analyzed using several indictors as carried out by [21], [22] and [23] namely.…”

Peningkatan Hasil Padi Melalui Penerapan Pengelolaan Hara Spesifik Lokasi di Lahan Sawah Tadah Hujan

“…Varietas Inpari 32 merupakan salah satu padi varietas unggul baru yang mempunyai potensi hasil tinggi yaitu 8,42 ton/ha. Hasil penelitian Romdon et al (2021), diketahui bahwa pemupukan berdasarkan hasil uji PUTS di Kabupaten Tegal dengan dosis 2 ton/ha bahan organik, Urea 200 kg/ha, dan Phonska 300 kg/ha mampu meningkatkan hasil padi Inpari 32 sebesar 20,36% dibanding eksisting petani. Lebih lanjut Erythrina et al (2021), menyampaikan bahwa pengelolaan tanaman terpadu di lahan sawah tadah hujan mampu meningkatkan produktivitas padi sebesar 1,925 ton/ha atau 60,85% lebih tinggi dibanding pengelolaan eksisting petani.…”
