Effect of Composted Municipal Solid Waste and Npk Fertilizer on the Growth and Yield of Maize (Zea Mays L) in Nsukka

ABSTRACT Municipalities are facing a growing problem of how to safely dispose off their wastes. Municipal solid waste (MSW) is waste from households, commercial centres, and institutions (school, offices). Composting is used to reduce huge pile of biodegradable MSW and convert it into value-added product like manure and biogas. Inorganic fertilizer such as NPK also exerts strong influence on plant growth, development and yield. Two-year experiments were conducted in the Teaching and Research...

Impact of Illegal Small Scale Mining (Galamsey) on Cocoa Production in Atiwa district of Ghana

The mining sector is a very important segment of the extractive sector but has one of the most serious and disastrous environmental consequences; conflicting with the livelihood (especially cocoa farmers) and survival of resident communities. This study was conducted in Atiwa district of Ghana to assess farmer’s awareness of small scale illegal mining (Galamsey), its impact on cocoa production and livelihoods in the mining communities. Snowball sampling techniques were used. Data collected ...

The experiment was laid out in a randomized complete block design with three replications. Four varieties of cassava; TMS 01-...

Influence of Cowpea Lines As Green Manure on Growth and Yield of Carrots in Root-Knot Nematode Infested Soil

An experiment was conducted at the University of Education, Winneba, Mampong-Ashanti campus to determine the effect of some cowpea lines as green manure on the growth and yield of carrot in root-knot nematode infested soil.  Randomized complete block design with five treatments and four replications was used. The treatments were cowpea lines IT97K-570-18; IT97K-566-18; and IT00K-1150 as green manure, N.P.K (15, 15, 15) and control.  The results showed negative correlation between root-knot ...

Climate Change Awareness and Coping Strategies of Cocoa Farmers in Rural Ghana

The study assessed the perception of farmers on the awareness, causes and impact of climate change on their farming activities. The study further identifies and describes the various coping strategies adopted by farmers and ways of improving upon them to effectively tackle change in climatic conditions. The collected data were analyzed using descriptive statistics, such as frequencies, and percentages. The other key technique that was employed to address the objective includes the Chi squ...

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...

Multi location Performance Evaluation of Exotic Hybrid Rice (oryza sativa l.) Varieties in Eastern Zone of Tanzania

ABSTRACT  Three exotic hybrid rice genotypes, HEU 022, HEU 188 and HEU 528 from China were tested to evaluate their stability and adaptability in the eastern agronomic zone of Tanzania. Three commonly grown varieties, SUPA, SARO 5 and TXD 88, were used as checks. A Randomized Complete Block Design (RCBD) experiment with three replications was carried out at four locations, ARI-Cholima, ARI-Katrin, Sokoine University of Agriculture (SUA) and Kilangali Rice Seed Farm all located in Morogoro Re...

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...

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...
