Abstract
Suitable variety and optimum plant density selection is necessary for silage production. A field experiment was conducted to find out the maize hybrid varietal performance under different planting density for silage biomass production in Dang Valley in 2021. The experiment was laid out in two factorial Randomized Complete Block Designs with three replications. The treatment consisted of combination of five different hybrid varieties (C1415, MM1107, RH-10, JKMH502 and CP808) and three plant densities (111,111 plants/ ha, 66,666 plants/ ha and 47,619 plants/ ha). The study revealed that variety MM1107 produced highest biomass yield (85.21ton/ha) which was significantly superior over other varieties. MM1107 had higher biomass yield due to higher plant height, leaf area, leaf area index, fresh weight per plant and moisture content and was also better in terms of emergence percentage. Highest biomass yield (91.68ton/ha) and dry matter yield (38.39ton/ha) was found at plant density of 111,111plants/ha. A positive linear relationship was found between silage biomass yield and plant density within the range 47,619-111,111plants/ha. Therefore, variety MM1107 and plant density of 111,111plants/ha performed better for silage production in Dang.
