Abstract: Linseed (Linum usitatissimum L.) is one of the oil crops cultivated in the highlands of Ethiopia. Its average yield is low largely due to several poor agronomic practices, biotic, and a biotic factor, among which non optimum sowing dates, seed rates, inorganic fertilizer, and improved varieties usages are the major ones. Consequently the field experiment was conducted in Horo Guduru district during the 2019 and 2020 with five objectives: (1) to identify the effect of sowing dates a...
Abstract: Use of inappropriate fertilizer type and rate, cultivation of unimproved low yielding varieties and low soil fertility are among the major constraints limiting the productivity of wheat in Ethiopia in general and in particular to the study area. Thus, field experiment was initiated to evaluate the effects of blended NPS fertilizer rates on yield components and yield of bread wheat varieties and to identify economically feasible rates of blended NPS fertilizer in the study area. The...
Abstract: One of the basic agronomic practices to improve the yield potential of common bean is identification of optimum plant spacing. Thus, field experiment was conducted to assess the effect of inter-row and intra-row spacing on the yield and yield components of common bean using variety Dursitu (DOR-811) at Chiro District in eastern Ethiopia. The treatment consisted of four inter- row (20, 30, 40 and 50cm) and four intra- row (5, 10, 15 and 20 cm) spacing arranged in factorial combinati...
Abstract: Common bean (Phaseolus vulgaris L.) is highly preferred by Ethiopian farmers because of its fast maturing characteristics that enable households to get cash income required to purchase food and household needs when other crops have not yet matured. However, the current national average yield of common bean is far less than the attainable yield under good management conditions for most improved varieties. This low yield of common bean in Ethiopia is attributed to several production ...
Abstract: Low soil fertility and poor crop management practices including useof inappropriate seeds rates are among the major constraints limiting the productivity offood barley in Ethiopia in general and in the study area in particular.Thus,field experiment was conducted to assess the effect of blended (NPSB) fertilizer and rates of seed on growth,yield components and yield of barely;and to estimate economically feasible of blended (NPSB) fertilizers and rates of seed for barely production ...
Abstract: A field experiment was conducted to study the responses of faba bean (Vicia faba L.) to phosphorus fertilizer rates and plant population at Haramaya University, Rare research site during 2019/2020 cropping season. Factorial combinations of four phosphorus (P2O5) levels (0, 23, 46, and 69 kg/ha) and six plant populations (133,333; 166,667; 200,000; 222,222; 250,000 and 300,000 plants ha-1 respectively were tested. The experiment was laid out in a randomized complete block design (RC...
Abstract: Potato is the second most important and co-staple crop in eastern Ethiopia. However, the average tuber yield is low as compared to the potential yield of the crop. The use of proper types and rates of fertilizer is one of the measures to increase productivity of the crop in the region. Therefore, a field experiment was conducted to evaluate the effect of combined application of blended NPS and Urea fertilizers on growth, yield components, tuber yield and tuber quality of potato at ...
Abstract: Low soil fertility and poor crop management practices are among the major constraints limiting the productivity of bread wheat in Ethiopia in general and Hulbareg District in particular. Therefore, a field experiment was conducted in Hulbareg District during the 2019 main cropping season to evaluate the effect of blended NPSB fertilizer rates on yield and yield components and to determine the economically feasible rates for bread wheat production. Factorial combination of three imp...
Abstract: Common bean (Phaseolus vulgaris L.) is an important source of food and income in East Hararghe Zone, Ethiopia. However, the extent of its on-farm diversity and conservation by smallholder farmers is not well known and no sufficient information is available on the characteristics of the genotypes for production and breeding purpose. Likewise, maize is a highly productive, multi-purpose crop and the cheapest source of calorie among the cereals and it is well-suited for diverse croppi...
Abstract: The experiment was conducted in Haramaya University beef farm from July 2019- June 2020 with the objective to investigate milk production, milk composition and calve growth performance(birth weight,weaning weight and daily weight gain) of ogaden cattle under improved feeding management. Sixteen lactating cows from early to late lactation stage were used by Randomized complete block design to receive four treatment diets. The supplementation was given based on cow’s daily milk yie...
ABSTRACT--- This experiment was carried out to determine the performance and carcass quality of broilers placed on pro-vitamin A cassava and sweet cassava-based diets using maize-based diet as control. The results show that daily weight gain of birds placed on maize-based diet (19.67g) was statistically higher (p0.05) among themselves. The average daily feed intake of the maize- based diets (54.07g/day) was significantly higher (p0.05) between each other. The feed conversion ratio of 2.75...
Abstract: Environmental friendly pre-treatment of fibre has been lately adopted by many researchers worldwide but not fully understood. Although various chemical modifications of fibre through several chemical treatments have been explored, but less has been done on lower sodium hydroxide (NaOH) concentrations. This paper investigated the effect of thermalization at 115 C and lower NaOH of concentrations (1, 3 and 5) effect on mukwa wood flour as a way of minimizing chemical impact on possib...
Abstract: Termite mounds are replete with natural nanoparticles, and they vary in physicochemical, geochemical, mineralogical, and biological properties from the adjoining soils. Although termite mounds have wide ecological and environmental roles including soil formation, faunal and vegetation growth and diversity, organic matter decomposition, geochemical exploration, water survey, treatment of underground contamination, thermoregulation, gas exchange, and global climate change, their nano...
Abstract: Advancement of knowledge on soil microbial richness is a key to environmental policy and sustainable land management. In Botswana, there is a dearth of scientific reports on soil bacterial dynamics. The aim of this study is to improve our understanding of how soil physico-chemical properties influence bacterial abundance and distribution under different land-use types (ecosystems). Six ecosystems studied include saline soil, sewage sludge dump, garden, fallow land rainfed and irrig...
Abstract: Diversifying tourism products is a vital contemporary business strategy for maintaining a competitive advantage in the face of rapid technological, economic and social changes. Tourism in Botswana is largely dependent on wildlife and international tourists and consistent calls to diversify over the past four decades have greatly been amplified by the colossal impact of the COVID-19 pandemic. A semi-systematic literature review analyzed progress and research trends related to touris...
