“Increasing nitrogen fertilizer rate from 30 up to120 kg N/feddan led to a significant increase in plant height, number of leaves/plant, number of tillers/plant, leaf area index (LAI) and fresh and dry forage yield t/feddan in the three cuts during the two studying seasons, as well as crude protein percentage in the first cut at both seasons and in the third cut of the second season only.”
