Abstract: This study aims to evaluate the improved forage legume potential for pasture land improvement in low-land and mid-land areas of East Shewa and West Arsi zone of Oromia regional state during 2021/22 planting seasons. The natural pasture grazing land was selected to establish the experiment. The experiment was undertaken with RCBD design. The ripping was done before sowing and animal manures were applied before establishment to facilitate the germination of legumes forage. The experiment has four treatments with three replications including the control. The plot size was 4 m * 3 m and the distance between the plot and block were 1m and 1.5m respectively. The sample was taken by quadrant of 1 m * 1 m, weighed, and inserted into a paper bag. The sub-sample was taken for dry matter determination and biomass estimation. Laboratory chemical analyses for some of the major parameters have been done at ATARC. The feed sample was analyzed for dry matter (DM) and crude protein (PC) using AOAC (2000) method. The statistical analysis was undertaken by ANOVA procedures with Tukey's Studentized Range (HSD) Tests to separate the mean values for each parameter at P<0.05. Analysis of variance revealed that variations of sites and treatments had showed a significant effect at (P<0.05) on dry matter yield and ADL. In addition, the site effects had showed significant effects on leaf to steam ratio, percentage of dry matter, percentage of ash and coverages. The ANOVA result showed that there was no interactions effect (P<0.05) for all parameters. In addition, the dry matter have significance difference (P<0.05) between the treatments due to different legumes integration. The integrated siratro (T4) and desmodium (T3) have higher mean value of dry matter than the other treatments. Of the total dry matter, the Desmodium have 10.88% proportion while the Siratro have about 49.57%. In general, improved forage legumes integration result indicated that as to be appropriate option for natural pasture improvement in terms of quantity and quality. Thus, of the treatments the demodium and siratro components have higher dry matter and crude protein the T3 and T4 were recommended for natural pasture improvement in terms quantity and quality for lowland and midland agroecology.

Abstract: Now a day human population increasing rapidly and cause land shortage land degradation, and poor soil fertility. Intercropping provides an opportunity to harness available resources by the cultivation of two or more crops planted simultaneously in the same land to produced cereal-legume for food and feed. A field study was conducted in Fedis District in 2018 to determine the impact of intercropping early maturing sorghum varieties and cowpeas on the land productivity and competition index. With a total of 11 treatments; two cowpea cultivars (9333 and 9334) and three varieties of early maturing sorghum (Teshale, Birhan and Melkam), their intercropping and sole cropping were determined using a randomized complete block design with three replications. Intercropping of sorghum-cowpea varieties produced significantly higher total land productivity than sole cropping of both varieties. The value of land equivalent ratio ranges from 1.21 for Sorghum (Teshale) + Cowpea (9334) to 1.36 for sorghum (Birhan) + cowpea (9333) and the overall mean was obtained as 1.30. The Percentage of the land saved of grain yields obtained was ranges 17.37% to 26.47% from of sorghum Teshale + cowpea varieties (9334) to sorghum Birhan + cowpea varieties (9333) and for Biomass yield production recorded from 27.01% to 36.71% that obtained from sorghum Melkam + cowpea (9333) and sorghum Birhan + cowpea (9334). Intercropped of sorghum-cowpea over all mean 23.25% for grain yield and 31.515% for biomass land was saved than sowing alone. Based on the result sorghum-cowpea intercropped, had the strength of relationship interaction and compatible; preferably sorghum Melkam + cowpea (9333) appropriate to increase the productions in study area and with similar agro-ecology.

Abstract: The experiment was conducted on yearling Guraghe bulls, with an average initial body weight of 111.91 ± 3.98 kg, to evaluate their growth performances and carcass characteristics under three different feeding options and to identify the most economical dietary rations. Twenty-one experimental bulls were randomly assigned to three dietary rations: T1 = Rhodes grass hay ad-libitum + 20% molasses + 40% wheat bran + 40% noug seed cake, T2 = Rhodes grass hay ad-libitum + 20% maize grain + 45% wheat bran + 35% noug seed cake and T3 = Rhodes grass hay ad-libitum + 65% wheat bran + 35% cotton seed cake. The bulls were acclimatized to the experimental diets for days, and the actual feeding trial lasted for 26 weeks. The animals’ weights were recorded at 14-day intervals. At the end of the 26 weeks three bulls from each treatment group were randomly selected for carcass evaluation. There were no significant differences (P>0.05) in live weight parameters and carcass characteristics among the treatments. The overall means for total weight gain, average daily gain, and carcass dressing percentage were 112.86 kg, 620g/day, and 57.34%, respectively. The yearling Guraghe bulls did not reach export market weight within 26-weeks of the feeding period. Additionally, the partial budget analysis indicated that fattening yearling Guraghe bulls with the current feeding options were not profitable. This suggests that fattening Guraghe bulls with the current feeding options for twenty-six months is economically not viable. It is recommended to evaluate the growth performances of Guraghe bulls with other feeding options to achieve an export market weight of 250-300 Kg.
