Abstract: aize is the major food crop in western Ethiopia and is produced in a number of agro ecologies. However, its productivity is constrained by erratic and low amount of rain fall and little availability of high yielding variety applications. Therefore, a field experiment was conducted during the 2019 main cropping season in Haramaya University of eastern Ethiopia on rare research field. The objectives of the study were to determine the effect of different tied ridge planting methods an...
Abstract: In cotton production of Middle Awash, information on the effect of inter- and intra- row spacing on lint yield, yield related traits and fiber quality of cotton are scarce. Therefore, the objective of this study was to assess the effect of inter- and intra- row spacing on lint yield, yield related traits and fiber quality of cotton. The study was conducted at Werer Agricultural Research Center’s experimental site in 2019 main cropping season on chromic vertisol (clay to silty cla...
Abstract: Population density is an important agronomic management practices in the production of potato (Solanum tuberosum L.). However, potato farmers in Ethiopia often use random population density, which contribute to the low yield of the crop. The experiment was conducted at Burka Woter in model farmers in Kersa District, East Hararghe Zone during main cropping (meher) rain season of 2019, with the aim to assess the effect of intra and inter row spacing on growth, yield related traits an...
Abstract: Bread wheat (Triticum aestivum L.) is an important food crop and source of income for farmers at Degam district in central highland of Ethiopia. However, its productivity is mainly constrained by poor soil fertility and lack of site specific fertilizer (NPSB) recommendation in general and in the study area in particular. Thus, field experiment was conducted at Degam district on farmer's field in 2019 main cropping season to investigate the response of bread wheat varieties to blend...
Abstract: Common bean is among the most important food and cash legume crops cultivated in southern Ethiopia. But, its productivity in the country remains far below the genetic potential to be attained. This is partly due to low soil fertility management and a lack of improved varieties. Therefore, the study was conducted to evaluate the effect of blended NPSB fertilizer rates on growth, yield components and yield of common bean varieties and to assess economic feasibility of common bean var...
Abstract: One of the basic agronomic practices to improve yield potential of chickpea is identification of optimum plant spacing. Thus, field experiment was conducted to assess the effect of inter-row and intra-row spacing on the growth, yield components and yield of chickpea variety at Haramaya District at main season. The treatment consisted one chickpea variety namely Habru, three inter- row (20, 30 and 40 cm) and four intra- rows spacing (5, 10, 15 and 20 cm). The experiment was laid out...
Abstract: Bread wheat is one of important food crop in the study area, but its productivity is limited by poor soil fertility. Thus, the study was conducted to investigate the effect of blended NPS fertilizer rates on yield and yield-related traits, nutrient use efficiency and grain quality of bread wheat varieties and assess their economic feasibility. Factorial combination of three bread wheat varieties (Senate, Mandoyu and Local) and six fertilizer rates (0, 50, 100, 150, 200, and 250 kg ...
Abstract: Potato (Solanum tuberosum L.) is one the most important food and cash generating crops in the eastern parts of Ethiopia, particularly East Harerghe zone, where it is grown three times per year. However, the average yield of potato is low, due to low soil fertility and poor ferti lizer management practice. Therefore, a field experiment was conducted in 2021 at Damota, Haramaya district, with the objectives of assessing the influences of integrated use of Farm yard manure and NPS ble...
Abstract: Sugarcane (Saccharum officinarum l.) is an important industrial crop that is used for sugar production in Ethiopia. However, the yield and yield component of sugarcane crop is limited by lack of site-specific appropriate agronomic practices related to fertilizer management in Ethiopia. The effects of new blended NPS fertilizer optimum rate specific to sugarcane variety was not known at study area. Therefore, a field experiment was to assess the effects of blended NPS fertilizer rat...
Abstract: Black cumin (Nigella sativa L.) is one of the most important spice and medicinal herb which is produced mainly by smallholder farmers in Ethiopia. However, the seed yield of the crop is low due to a number of constraints out of which low soil fertility, random plant spacing, and sowing of the seeds by broadcasting are the major ones. Therefore, field experiments were conducted in Ambo and Dandi districts in West Shewa Zone of Central highlands of Ethiopia to investigate the effect ...
Abstract: One of the basic agronomic practices to improve yield potential of chickpea is identification of optimum plant spacing. Thus, field experiment was conducted to assess the effect of inter-row and intra-row spacing on the growth, yield components and yield of chickpea variety at Haramaya District at main season. The treatment consisted one chickpea variety namely Habru, three inter- row (20, 30 and 40 cm) and four intra- rows spacing (5, 10, 15 and 20 cm). The experiment was laid out...
Abstract: Climate change is a key emerging threat to the lives and livelihoods of smallholder farmers in Ethiopia. This study examines small-scale farmer adaptation strategies to climate change and climate variability, and the factors affecting adaptation choice inJimma, Southwestern Ethiopia. This research used a ‘bottom-up’ approach, which seeks to capture insights from the farmers. Primary data was collected through a household survey, focus group discussions and key informant intervi...
Abstract: This study sought to examine the collaborative participation approach and technology adoption. The objective of this study was to determine the linkage between socio-economic factors in collaborative participation and technology adoption and diffusion among Trans Nzoia district resource-limited farmers. Collaborative participation involves farmers, researchers, and extension agents in developing and disseminating technology. The study reviewed the push/pull’ technology of control...
Decline in yields and frequent failure of major crops in Embu and Kiambu counties, Kenya, is linked to inadequate or unevenly distributed rainfall and poor agronomic practices, among other factors. The main objective of this study was to evaluate the effect of using mulch and hydrogel in production of yellow passion fruit in Embu and Kiambu Counties, Kenya. The study was set up specifically to (i) determine the effect of mulch and hydrogel on soil moisture and nutrients in a yellow pass...
ABSTRACT Rice is relatively new to Uganda, yet consumption is outstripping production; and with a growing population, demand is likely to increase. NERICA (New Rice for Africa) rice – with high yields and ability to withstand dry conditions is being planted in most part of the country. However, weed infestation is becoming one of the biggest hindrances affecting rice production. The objective of the current work was therefore to investigate the effects of varietal differences, plant spacin...
