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: 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...
ABSTRACT Green pepper (Capsicum annuum) is one of the most important and remunerative vegetable crops. Row spacing and mulching are important factors that influence water use, weed suppression, growth, quality, and yield of vegetables. Due to increased pressure on land, climate change and increased demand for vegetables, there is need for deployment of optimal agronomical practices that will ensure enough food production. This study was undertaken to determine the optimum spacing and mulching...
ABSTRACT Drought is a major abiotic factor limiting crop productivity in many regions of the world. It causes reduction in plant growth, dry matter accumulation and decline in plant water status of the plants and in certain cases interferes with biochemical processes within cultivated crops. The aim of the study was to map out the distribution of different African Nightshade species in Siaya and Kisii Counties of Kenya and to determine water stress effect on total antioxidant capacity and tot...
ABSTRACT Ultraviolet (UVB) radiation (280–315 nm) and interaction with Selenium (Se) have potential promoting plant tolerance to UVB stress in plants and modify metabolites that influence taste and functional properties of tea. The objectives of this study were to assess sensitivity of two tea varieties to ambient solar UVB radiation and Selenium nutrition on 1) yield components,2) secondary metabolites, antioxidant activity, theanine and mineral composition of tea and 3) non-aerated (gree...
Rice is a staple food and the main source of calories and proteins for more than half of the world population. Its increasing demand in Africa made it a commodity for food security and poverty reduction. Rice ranks third in Kenya’s staple food after maize and wheat. Its consumption has been growing rapidly due to urbanization and changing eating habits in both rural and urban households. In 2014, local rice production was estimated at 129,000 metric tonnes, while consumption was 548,00...
ABSTRACT Rice is considered main source of calories and protein especially in many countries of Africa as it constitutes a major part of the diet. It is steadily becoming a major staple food for many households in Kenya as annual consumption has increased by 12 % for rice; compared with 4% for wheat and 1% for maize hence, increasing its productivity is paramount, as eating habits changes especially among the youth. Threat of climate change continues to impede agricultural activities, resulti...
