Evaluation of maize hybrids and composites for fodder yield and ensiling quality

Abstract

There are number of hybrids and composites in maize which are used for silage making by farmers. The objective of the present study was to find out the promising high yielding and better-quality silage cultivar. A study was undertaken during, 2019-20 and 2020 in randomized block design (RBD) with three Rabi Kharif replications consisting of 13 maize hybrids and three composites. The African Tall recorded significantly higher plant height (333.39 cm), number of leaves/plant (13.83) and green fodder yield (51.92 t/ha) compared to all other hybrids and composites. While dry matter yield was higher in maize hybrids, P 3401(16.85 t/ha) followed by DMRH 1410 (15.45 t/ha). Crude protein yield (1.09 t/ha) was also higher in P 3401 followed by PMC 6 and P 3396 (1.01 t/ha). The pH of silage in all maize genotypes was in acceptable range. NDF content varied from 49.48 to 55.11% and 53.19 to 59.39% in green fodder and silage stage, respectively. ADF content varied

between 24.45 to 28.55% in green fodder and 28.74 to 33.34% in silage. But difference was found non- significant for both NDF and ADF in silage and green fodder. Based on this study African Tall, P 34 , 01 and

DMRH 1410 were identified as promising maize genotypes for higher biomass yield and quality silage preparation for ruminant animals.
