Abstract

A field experiment was conducted at the Agricultural Faculty Farm of New Valley University during the winter seasons of 2020/2021 and 2021/2022 in order to investigate the potential of enhancing forage production, yield, and the various components of two barley (Hordeum vulgare L.) cultivars by employing varying seeding rates along with different cutting dates. The study laid out in a randomized complete block design (RCBD) under split split-plot arrangement and three replications. The most important results included: Giza 133 barley cultivar had a higher green fodder yield/fad., plant height, number of tillers/m2, number of spikes/m2, grain yields/fad and harvest index in both seasons as well as, straw yield and total dry matter/fad. in the second season only. Dry fodder yield (ton/fad.), plant height, number of tillers/m2, number of spikes/m2, grain and straw yields/fad as well as total dry matter/fad. had a significant response to increase seeding rate in both seasons, where it increased gradually by increasing seeding rate from 45 to 50 or 55 kg/fad. Cutting date had a highly significant effect (P≤0.01) on amount of green and dry fodders/fad., yield attributes traits, grain and straw yields/fad. as well as total dry matter/fad. and harvest index in both seasons. Sowing Giza133 at a rate of 50 kg grains /fad and leaving it without cut recorded the highest grain yield/fad. in the two seasons. Sowing Giza133 barley cultivar at seeding rate of 50 kg /fad. and the cutting at 65 days recorded the highest significant total dry matter/fad. in the two growing seasons.
