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.
