Abstract
Split-application of urea fertilizer experiment was conducted in major early maturing one local (Jiguritie) and one improved (Girana-1) sorghum varieties growing areas of Eastern Amhara Region namely Sirinka, Gedober, Mersa, Chefa, Jari and Kobo for two years (2013-2014). The principal objective of the experiment was to identify the response of timing of Urea fertilizer application on grain yield of sorghum. The experiment was designed in randomized complete block consisting of five Urea fertilizer (111 kg/ha) application times: (1) full-dose at knee height stage, (2) 1/2 at planting + 1/2 at knee height stage, (3) 1/3 at planting + 2/3 at knee height stage, (4) 1/3 at planting + 1/3 at knee height stage + 1/3 at stem elongation and (5) 1/2 at after thinning + 1/2 at knee height stage for early maturing sorghum varieties (Jiguritie and Girna-1) replicated three times were used in the study. Basal application of 46 kg/ha P O 2 5 fertilizer was made at sowing. The result revealed that split-application of Urea fertilizer had significance difference between yield components of sorghum. Mean combined in two years were showed that the highest grain yield (4314 kg/ha) was recorded with application time of Urea fertilizer 1/2 at after thinning + 1/2 at knee height stage of Jiguritie sorghum. Similarly, the highest grain yield (4868 kg/ha) was recorded with application time of Urea fertilizer full-dose at knee height stage of Girana-1 sorghum. By considering the moisture availability of the areas, it was recommended that the best use of Urea fertilizer would be obtained when 1/2 after thinning + 1/2 at knee height stage at Kobo, Sirinka, Jari and Mersa while 1/3 at planting + 2/3 at knee height stage at Chefa and Gedober areas for Girana-1 sorghum while 1/2 at after thinning + 1/2 at Knee height stage was for Jiguritie sorghum
