Abstract

Two field experiments were conducted at farm of Fac. Agric., Al-Azhar Univ., Sadat Branch, at Menoufia Governorate, Egypt. during 2020 and 2021seasons. The investigation aimed to study the effect of thirteen fertilization treatments i.e. control (0), N at a rate of 30 and 45 kg N /cut, P at a rate of 7.75 and 12.92 kg P2O5 /cut and K at a rate of 16.67 kg K2O /cut and their combination on growth, fodder yield and its quality of two forage crops i.e. sudan grass var. Giza-2 and single hybrid sorghum "Mabrok" in sandy soil condition. The obtained results showed that Single hybrid sorghum "Mabrok" surpassed Sudan grass in plant fresh weight, protein percentage and fodder yield/feddan in both seasons. Application of 45 kg N + 12.92 kg P2O5 + 16.67 kg K2O/cut gave the highest values of all studied characters as compared with the tested other fertilization treatments in both seasons. Fertilized Single hybrid sorghum "Mabrok" with of 45 kg N + 12.92 kg P2O5 + 16.67 kg K2O/cut gave the highest values of plant fresh weight, protein percentage and fodder yield/feddan as compared with other tested treatments in both seasons.
