Abstract

The study was conducted at Elmukabrab scheme in River Nile State. Soil was low in nitrogen and of few organic meters. during the years 2012/ 13 and 2013/14 with the objective of investigating the effect of Acacia ampliceps shelterbelt and water use in rows wide 5 m between hedge rows and 3 m spaces between trees on growth and yield of Barley (Hordeum vulgare L.) as forage crop . Treatments consisted of heavy pruned Acacia ampliceps shelterbelts with light intensity of about 60 to 65% compared with control (light intensity 100%). Heavy pruning was done to increase incoming radiation measured by solar meter in two different seasons. Treatments were arranged in a randomized complete block design with four replicates. The plot size was 6×5 m.. Results revealed that in both seasons Barley forage yield under shelterbelt was highly significant, compared with the control. Barley fresh and dry forage yield under shelterbelt was increased by 46, 42% in the first season and by 41, 59% in the second season respectively compared with the control. In addition, water applied in shelterbelts with barley was measured. Water consumption differed (p<0.001) between shelterbelt and mono-cropping systems. Shelterbelts plots consumed less water (739m3) than the control (883m3). Water was saved in Acacia ampliceps shelterbelt by 23 and 26% for barley cultivars in the first and second seasons, respectively.
