Evaluation of some indicators of nutritional and forage value of several varieties of local barley (Hordeum vulgare L.) under the influence of early and late planting systems in the first stabilization area

Abstract

 The experiment was carried out on seven varieties of local barley (Furat 1, Furat 2, Furat 3, Furat 4, Furat 6, Furat 9, and Arabian whight) in the Kafr yahmoul area in (the first stabilization zone) in order to determine the optimal date for planting the variety that corresponds to the highest nutritional and fodder value, within the design of random pieces (R.C.B.D) and in the way of splintering pieces on the dates of the first (18/11/2021) and the second (1/1/2022).The varieties of the first date recorded superiority in the percenage of total humidity, total fat and total in the whole plant compared to the second date with significant differences (P<0.01) on the one hand and in the percentage of ash and total protein in barley grains on the other hand. In the second date the cultivated varieties were characterized by a high percentage of dissolved carbohydrates in the entire plant on the one hand and a high in the percentage of organic matter and total fat in cereals with significant differences (P<0.01) on the other hand compared to the first planting date .The variety had an impact on the fooder value in the entire plant at the time of flowering where the total humidity of the varieties increased in Furat3 with significant differences (P<0.01) compared to the rest of the varieties and the percentage of organic matter in the variety Furat1 with significant differences (P<0.01) compared to the rest of the varieties. The varieties Furat6, Furat2, Arabian white and Furat9 exceeded E.E, C.F, C.P and N.F.E by significant differences(P<0.01) out performed the rest of varieties. Respectively as for the gain content, the varieties Furat2, Furat9, Furat4, Furat6 and Furat1 recorded a decrease in indicators of total ash, E.E, C.P, N.F.E, C.F respectively and with significant differences(P<0.01). An impact of the interaction is found between date and the varieties as the varieties Furat9 and Furat4 in the first date recorded an increase in the percentage of total protien and carbohydrates dissolved in the entire plant at the time of flowering and in cereals the percentage of total rose in Furat4 lately cultivated and C.F in Furat6 lately cultivated. Arabian white lately cultivated with Furat1 early cultivated, had the highest value of the percentage of dissolved carbohydrates respectively
