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.
