Adaptation test of various dry-land composite corn varieties in Sigi regency, Central Sulawesi

Abstract

The study aims to determine the adaptation of several varieties of composite corn in dry land. The study was carried out in Bulili Village, Nokilalaki Subdistrict, Sigi Regency, Central Sulawesi Province with an area of 6 hectares, conducted in March to June 2019. The research design used was Randomized Design, consisted of four composite corn varieties (Sukmaraga, Lamuru, Srikandi Kuning and Anoman) as a treatment with eight replications. Variability adaptation test is equipped with an economic feasibility analysis and farmer perception to composite corn. Data were analyzed using analysis of variance (F Test) and Duncan’s Multiple Range Test (DMRT) at 5% level. Economic feasibility was measured using RC ratio while farmer perception was measured by scoring methods. Materials and tools used include composite corn seeds, Dry Soil Test Equipment, and scales. Adaptation observation parameters include growth and yield components. The results of the study showed that the Lamuru variety gave a significantly different growth and yield compare to Sukmaraga, Srikandi Kuning and Anoman varieties. Appropriate and high-yielding varieties at the study site were Lamuru and Sukmaraga (8 t /ha) and the lowest was Anoman (7 t / ha). All economically feasible which respectifully RC ratios are Lamuru 1.30, Sukmaraga 1.30, Srikandi Kuning 1.22; and Anoman 1.17.
