Abstract

A field experiment was conducted at the Agric. Res. Station, Fac. Agric., Zagazig Univ., Sharkia Governorate, Egypt, during the winter seasons of 2019/2020 and 2020/2021. The investigation aimed at studying the impact of ten bio-chemical phosphorus fertilization and lithovit regimes on some qualitative traits of forage for 1stand 3rd cuts of six Egyptian clover varieties (Berseem, Trifolium alexandrinum L.) q.e. Helaly, Sakha 4, Gemmeiza 1, Giza 6, Serw 1, and local variety. The ten bio-chemical phosphorus fertilization and lithovit regimes were F1, control; F2, chemical phosphorus, 15.5 Kg P2O5 /fad., F3, bio-phosphorus fertilizer “Phosphorien”; F4,50% of F2 + phosphorien; F5, 25% of F2 + phosphorien; F6, F2 + lithovit; F7, F3 + lithovit; F8, F4 + lithovit; F9, F5 + lithovit; F10, sole lithovit. Results disclosed varietal differences in each of phosphorus content (P%), digestible energy (DE Kcal/g dry matter), protein yield (Kg/fad.), as well as carbohydrate and fiber yields (Kg/fad.) in both the 1st and the 3rd cuts. The ten bio-chemical phosphorus fertilization and lithovit regimes resulted in a significant impact on the above cited traits in both the 1st and the 3rd cuts.
