Performance of New Superior Varieties of Hybrid and Composite Corn in Papua

Abstract

One effort to increase corn production is through the use of new superior varieties (NSV) hybrid corn and composite corn. This study aims to determine the performance of growth and yields of four NSV hybrid corn and composite corn. The study was conducted in Merauke Regency, Papua since August to December 2018. The design used was Randomized Group Design (RGD) based on one factorial with 5 sub factors, each hybrid corn; HJ 21 Nasa variety, Nasa 29 variety and composite corn; Lamuru variety, Bisma variety, Sukmaraga variety. The results of the study at various ages of plant height were not affected significantly, the number of leaves were significantly affected by 30 days after planting (DAP) and at harvest time. Leaves width at various ages had no significant effect, while leaves length and stem diameter were all observed at the highest leaf length with the effect of 30 days after planting (DAP) Nasa 29 (75 cm) but 60 days after planting (DAP) and at harvest HJ 21 Agritan 93 cm. Then the largest stem diameter of Nasa 29 (1.7 cm) was 30 days after planting (DAP) and 60 days after planting (DAP)- at harvest was each 2.5 cm. Difference of the longest cob length of HJ 21 agritan 38.4 cm, diameter of the largest cob 5.1 cm, the highest number of lines per cob 15.8 seeds, the heaviest weight of 1000 HJ 21 Agritan 420.6 g, heaviest dry harvest Nasa 29 (12.4 t/ha) and the heaviest dry pipelines Nasa 29 (9.2 t/ha). The overall performance of the results significantly affected both hybrid corn and composite corn.
