Adaptation of superior maize varieties high yield and biomass the availability of animal feed

Abstract

Maize is the second important commodity after rice in Indonesia. The application of high yielding varieties is one of the best strategies to increase productivity in maize development areas. The aim of the study was to obtain superior varieties with the highest yield potential and biomass to increase productivity and its availability as animal feed. The research was conducted in Pringgabaya district, East Lombok Regency, West Nusa Tenggara from April to June 2020. The field experiment used a randomized block design with treatment of 8 hybrid varieties, where six new superior varieties (Bima-14, Bima 20, HJ-21, JH-27, JH-37, Nasa-29) and two comparison varieties (Bisi-2 and Pioner 21), each treatment was repeated four times. The results showed that there were 3 high yielding hybrid maize varieties, namely JH-37 (8.43 t/ha), Nasa-29 (8.35 t/ha) and HJ-21 (8.15 t/ha) significantly differ from other varieties. For the highest biomass potential, there are 3 superior varieties of hybrid maize, namely HJ-21 (4.82 t/ha), Bima-20 (4.69 t/ha) and JH-27 (4.56 t/ha). High yielding hybrid maize varieties that available as animal feed were JH 37, Nasa-29 and HJ-21.

Determining the Grain Yield and Nutritional Composition of Maize Cultivars in Different Growing Groups

“…It was reported by the researchers that the differences in grain yield, test weight, and thousand grain weight may be caused by ecological factors and agricultural practices, particularly by cultivar traits (Bayisa et al, 2022). Erawati et al (2021) reported that each cultivar has a specific level of resistance and different genetic potential in responding to its environment. They also suggested that cultivars have the potential to provide high yields, but when environmental conditions are not favorable, then the variety cannot realize its full potential.…”
