Abstract

This investigation was conducted in a private farm at two field experiments in research farm of the Agricultural Research Center in the Sakha, Kafr El Sheikh Governorate, Egypt, under Agronomy branch supervision, Plant Production Department, Faculty of Technology & Development, Zagazig University, during the two successive summer seasons 2022 and 2023. This investigation aimed to study the effect of four planting dates T1 (1st may), T2 (15th May), T3 (1st June) and T4 (15th June) with four nitrogen fertilization levels (without N (N1), 20 kg N/fad. (N2), 30kgN/Fad. (N3) and 40 kg N/fad. (N4) on growth and green forage yield of Sorghum hybrid. A split-plot design with three replications was used in both growing seasons. The most important findings could summarized as follows: The results showed that planting date in 1st May ted to a significant increase in total fresh forage yield / fad. This increase compared to other planting dates (15 May, 1 Joune, and 15 Joune ) amounted to in the first season by 1.26% 15.9% and 25.75% and 37.78 , 52.73% and 80.12% in the second season and 10.80%, 14.55and 33.88% in the combined respectively. Also planting date in 1st May resulted significant increase in plant height, no of tillers, no of leaves / plant, fresh leaves/stem ratio and stem diameter. Increasing nitrogen level up to 40 kg /N fad. increase in total fresh forage yield fad. This increase compared to other nitrogen fertilization levels (0, 20 and 30 kg/fad.) amounted to in the first season by 60.59%, 26.03% and 11.81% and 62.61% 24.54% and 9.57% in the second season and 62.71%, 25.21% and 10.61% in the combined, respectively. Moreover, these results showed that increasing N-level from 0 up to 40 kg/fad. produced gradual and significant increases in plant height, no. of tillers, no of leaves / plant, fresh leaves/stem ratio, and stem diameter. Regarding the interaction effect, the treatments of sowing date in 1" May and nitrogen fertilization levels of 40 kg fad were recorded the highest values of most studied characters in this respect.   Conclusively, these results of this study recommended by the planting sorghum hybrid in 1th May and fertilizing with 40 kg N / fad. under condition of  Kafr El- Sheikh Governorate , Egypt.
