Abstract
A field experiment was carried out at the exp. Farm of The Agricultural research and extension authority ( AREA), during 2014/2015 seasons to determine the Effect time cutting and Cultivars on green and crud protein yield of Alfalfa (Medicago sativa L.) under Dhamar area Conditions, Dhamar Governorate.
This experiment contained 18 treatments which were the combination of three cutting time treatments(T): (40 days (T1),50 days (T2), 60 days (T3)) and six of Alfalfa Cultivars treatments (C): Sahli (C1) , Bahtidei(C2), Remani(C3), Saioni(C4), Koli (C5) and Mahli(C6).
The experiment split plot design in four replications was used. The study results showed the following :
Cutting time (T) gave significant effect on all of the traits under study: green yield, dry yield, percentage of crud protein% and crud protein yield in the both Growing seas ons. The late of cutting time from 40 to 60 days caused an increase in all of the traits under study, except the percentage of crud protein% in the both Growing seasons.
There was a significant effect for the alfalfa cultivars(C) in both Growing seasons. The Saioni alfalfa cultivar(C4) gave the highest values in all of the traits under study green yield, dry yield, percentage of crud protein% and crud protein yield, while the Sahli alfalfa cultivar(C1) gave less values in the same traits in both Growing seasons.
There was a significant effect for the interaction between alfalfa cultivars(C) and cutting time (T) for all studied traits in the both seasons.
