Livestock feed shortage as a result of grazing land degradation and crop failure due to shortage ... more Livestock feed shortage as a result of grazing land degradation and crop failure due to shortage and poorly distributed rain is critical in the Gumara-Maksegnit watershed. To assuage this problem identifying and planting feed crops with high water use efficiency that produce acceptable yield has to be considered in the watershed. An experiment was conducted to evaluate the adaptability and productivity of different Cactus cultivars under the ecological conditions of Gumara-Maksegnit watershed in the year 2012/2013 for 18 months. Six cultivars of cactus (Sulhuna, Gerao, Dilaledik, Gerwanlayele, Ameudegaado Belesa and Local cultivar) were used as experimental treatments. Cactus cladodes were planted using a Randomized Complete Block Design (RCBD) with three replications each. To assess their adaptability and productivity percent survival of cladodes, days taken to sprout, percent of plants sprouted, number of cladodes formed plant , size of newly formed 1 cladodes, average weight of cladodes and dry biomass yield were recorded. The results indicated that cactus cultivars evaluated showed statistically significant variation (p <0.05) in days taken to sprout, number of cladodes formed plant , width of cladodes (cm), average weight of cladodes (g) and dry biomass yield (t/ha) 1 while there is no any statistical significant difference (p> 0.05) recorded in percent of plants sprouted, percent survival of cladodes, length of cladodes (cm) and dry matter percent (DM%) of cladodes. From the cultivars evaluated Sulhuna, Dilaledik and Ameudegaado Belesa were significantly at par but higher than others in number of cladodes formed plant , average weight of cladodes and dry biomass production which are the best 1 indicators of the superiority of cultivars as a forage source and adaptation of cultivars to the environment. Thus according to the results of this study Sulhuna, Dilaledik and Ameudegaado Belesa varieties are recommended for wider use in the watershed and other similar areas.

This necessitates the need to follow economically viable forage production. A study was conducted to evaluate the yield and yield related performance of cowpea (Vignia unguiculata L.) varieties under irrigation in 2017 and 2018 years. The experiment was laid down in a split plot design with randomized complete block design (RCBD) arrangement in four replications. There were two main plots of which one was planted with fertilizer and the other one without fertilizer for comparison and the sub plot treatments were eight varieties of Cowpea (Vignia unguiculata) (ILRI 9333, ILRI 9334, ILRI 11114, ILRI 12688, ILRI 12713, Kenkety, Black eye bean and IT92KD258-9). The data collected consisted of plant height (cm), number of branches per plant, forage biomass yield (t ha

The present study reports on the ground nest architecture of the <em>Meliponula</em> stingless bees, impact of agricultural activities on the stingless bee population and traditional use of stingless bee honey in three districts—Wegera, Libo Kemkem and Alepha—of the Amhara Region, Ethiopia. The ground nests were located with the help of indigenous knowledge. The parameters of the <em>Meliponula</em> ground nests were measured and compared with published data. The impact of agricultural activities and the use of stingless bee honey (locally known as <em>tazima</em> or <em>tazma mar</em>) in ethnomedicine were documented through interviewing local communities and briefly discussed. It has been noted that stingless bee honey is used locally as a treatment for both infectious and non-infectious conditions and as an effective pain-relief measure. However, the stingless...

The sheep were treated against endo- and ecto- parasites before commencing the study. The experimental design was a Randomized Complete Block Design (RCBD) with six replications. The treatments were: natural pasture hay alone (T1), natural pasture hay+ 1noug seed cake (NSC): 1 wheat bran (WB) (T2), natural pasture hay + 2NSC: 1WB (T3) and natural pasture hay + 3NSC: 1WB (T4). The supplements were offered at the rate of 400 g/day, which were offered twice per day at 0800 and 1600 hours in equal portions. The feeding trial was carried out for 90 days after 15 days of adaptation period to the experimental feeds and conditions, which were then followed by carcass evaluation at the end of the study. Supplemented treatments had higher (P<0. 01) total DMI (7...

Background Understanding the relationship between dry matter yield production and forage quality ... more Background Understanding the relationship between dry matter yield production and forage quality throughout the growing season will help to optimize the cutting intervals between harvests in different Alfalfa (Medicago sativa L.) varieties. An experiment was conducted to assess the effects of harvest frequency on forage yield and quality of 2 improved cultivars (ILRI-6984 and var. DzF-552) of alfalfa (Medicago sativa L.) in Western Dembia district over 20 months during 2017 and 2018. Four harvest frequencies (every 30, 40, 50 and 60 days) were compared in a randomized complete block design (RCBD) with 4 replications. The experiment was laid down in a randomized complete block design (RCBD) in factorial arrangement with four replications. To assess their production potential plant height (cm), number of branches per plant, fresh biomass yield (t ha−1) and dry matter yield (t ha−1) of the forge and its nutrient content were recorded. The data collected was subjected to analysis of var...
