Although climate change affects everyone but its impacts are differently distributed among males and females. This study analyzed the gender differentiated impacts of climate change on agricultural production and the adaptation strategies by the farmers in the Nadowli-Kaleo District. The study adopted both qualitative and quantitative ...

EFFECT OF INTERCROPPED FORAGE LEGUMES AND THEIR POPULATION WITH SORGHUM (Sorghum bicolor L.) ON THE PERFORMANCE AND PRODUCTIVITY OF COMPONENT CROPS IN EAST HARARGHE, ETHIOPIA

Abstract: The shortage of arable land and shortage of livestock feed are major constraints in East Hararghe zone. Realizing the potential of intercropping to address this problem, a field experiment was conducted during 2020 crop season in East Hararghe, Ethiopia; To investigate the effect of intercropping forage legumes at different population with sorghum on the performance and productivity of component crops. Three forage legumes (vetch, lablab and cowpea) were intercropped at population ...

Abstract: Climate variability is affecting the whole world and its threat is greater in Ethiopia because of its less adaptive capacity and deepened poverty.This study was there fore designed to investigate the impact of rainfall and temperature variability on Teff crop performance and quantify their relationship at Kersa district of Jimma zone (1980-2015). Rainfall and temperature data were obtained from National Meteorological Agency(NMA) while Teff yield data collected from Kersa District ...

Technical Efficiency and Commercialization of Moringa and its Impacts on Food and Nutrition Security in Southern Nations Nationalities and Peoples’ Regional State of Ethiopia

Abstract: This study aimed at Moringa production efficiency analysis, commercialization, and evaluation of its food and nutrition security impacts at smallholder farm household level. It aims to fill the missing knowledge gaps through a cross-sectional survey study on data collected from selected 232 Moringa producer and 232 non-producer smallholder farmers from Wolaita and Gamo zones, southern Ethiopia. Descriptive statistics and econometric models were used to analyze data. First, the stud...

EVALUATION OF IMPROVED NAPIER GRASS (PENNISETUM PURPUREUM (L.) CULTIVARS UNDER FARMERS CONDITIONS IN WEST HARARGHE ZONE, OROMIA REGION, ETHIOPIA

Abstract: This study was conducted to evaluate the forage production, chemical composition, in vitro dry matter digestibility and rumen degradability potentials of improved Napier grass cultivars as well as their preference as livestock feed under farmer’s conditions in West Hararghe Zone of Oromia region, Ethiopia. Four improved Napier grass cultivars (ILRI cultivar number: 16801, 16800, 16798, and 16840) and local check were planted in a Randomized Complete Block Design (RCBD) with six r...

The Influence of Levels and Modes of Npk Fertilizer Application on Growth and Yield of Some Improved Varieties in Nsukka, South Eastern Nigeria

ABSTRACT A study was carried out at the Department of Crop Science, Faculty of Agriculture Experimental Farm, University of Nigeria, Nsukka to: (i) evaluate the growth and yield of four improved cassava varieties, (ii) determine optimum NPK fertilizer rate for increased productivity and (iii) determine the best mode of fertilizer application for increased productivity. The experiment was laid out in a randomized complete block design with three replications. Four varieties of cassava; TMS 01-...

Agronomic And Rodent Pests Management Practices By Maize Farmers In Ron Gal Division, (, '" Nakuru County

ABSTRACT Rodent damage to maize and other cereal crops is a chronic problem to Kenyan farmers and occasional outbreaks are reported. According to a report by the Ministry of Agriculture in the year 2008, damage of between 1 and 5 % are common but damages of 20-100 % have also been recorded. In this study, a survey was carried out in Rongai Division, a cereal growing region in the Kenyan Rift Valley, to identify the general crop husbandry and farm enterprises, knowledge on problem rodents, fa...

Effect of Different Water Harvesting Techniques on Growth and Yield of Pearl millet (Pennisetum glaucum) Intercropped with Cowpea (Vigina sinensis) in North Darfur.

Abstract Two field experiments were conducted for two consecutive rainy seasons of 2011/12 and 2012/13 at Umhojar Village, Kabkabiya Locality- North Darfur State, Sudan to study the effect of different rainwater harvesting techniques on growth and yield of pearl millet intercropped with cowpea. The area lies on sandy clay loam soil at Latitude 13o. 04" N and Longitude 24o.08" E,). Split plot design with four replicates was used in which five water harvesting techniques viz.; W1 (Terracing sy...

Evaluation Of Protocols For Regeneration Of Sweet Potato (Ipomoea Batatas (L.) Lam.) In Tissue Culture

ABSTRACT Tissue culture techniques have opened a new frontier in agricultural science for addressing food security and poverty issues. These techniques have involved development of suitable plant regeneration protocols that can reduce disease infestation by producing healthy plants rapidly and hence increase yields in Kenya. The current research focus in sweet potato (Ipomoea batatas (L.) Lam) has been the development of transgenic sweet potatoes, with ability to resist viral diseases of whic...

Occurrence, Distribution And Molecular Diversity Of Groundnut Rosette Assistor Virus Causing Groundnut Rosette Disease In Western Kenya

ABSTRACT Groundnut (Arachis hypogaea Linn) is an important legume in western Kenya, but yields are low and declining. Pests and diseases are ranked high among the yield reducing factors. Groundnut rosette disease (GRD) is the main disease and can cause up to 100% yield loss. Rosette is transmitted mainly by the groundnut aphid, Aphis craccivora Koch and to a lesser extent by Aphis gosypii Glover and Myzus persicae Sulzer. Rosette is caused by two synergistic viruses; groundnut rosette assisto...

Efficacy Of Leaf Extracts Of Artemisia Annua And Thevetia Peruviana Against Aphis Fabae And Non-Target Organisms On Solanum Scabrum

ABSTRACT African nightshade (Solanum scabrum Miller) is a vegetable, widely distributed throughout the tropics including East Africa. It is an important vegetable in Kenya but consumer demands have not been met due to low yields and partly due to attack by Aphis fabae Scopoli. The aphids cause serious damage through sucking plant cell sap from phloem leaving the plant weakened, dehydrated, stunted in growth and eventually under heavy infestation the leaves curl making the vegetables unattract...

Distributionand Characterization Of Groundnut Rosette Associated Virusesin Western Kenya

ABSTRACT Groundnut (Arachis hypogaea L.) is an economically important edible oilseed legume in Sub-Saharan Africa (SSA). Smallholder farmers, who account for 75% of producers, depend on it for food and income. However the yields are far below the world averages. Groundnut rosette disease (GRD) is a major constraint of groundnuts in Sub-Saharan Africa (SSA) causing up to 100% yield losses. The disease is caused by two synergistic viruses; groundnut rosette assistor virus (GRAV, genus Luteoviru...

Challenges Facing Chicken Production In Katulani District, Kitui County

ABSTRACT The poultry industry in Kenya is a key contributor to the local economy as well as food security and income with over 90% of households owning a flock of chicken (Kingori et al., 2010). The main objective of this study was to investigate the challenges faced by rural and peri urban chicken farmers in Katulani District, Kitui County. The study focussed on understanding the challenges affecting chicken farming, factors affecting technology adoption, access to institutional support serv...

Belowground Influence Of Farmer-Produced Composts On Soil Biota, Foliar Pests And Yields Of Common Bean (Phaseolus Vulgaris) In Western Kenya

ABSTRACT The production of common bean Phaseolus vulgaris in Kenya has been reducing due to declining soil fertility. The use of synthetic fertilizers has been linked to soil acidification, which constrains plant growth and interferes with beneficial rhizosphere biota. The application of composts is being encouraged, and farmers in Western Kenya are being trained on composting of locally available organic materials. However, there is need to establish the performance of such farmerproduced co...
