Economic efficiency of green maize intercropped with beans grown under Tithonia and inorganic fertilizer
(African Journal of Agricultural Research, 2015-11-20)A field trial aimed at assessing the performance of maize and beans under intercropped systems was conducted in 2013 under three experimental components of maize, beans and maize-bean intercrop in a randomized complete ... -
Interaction of Insects and Weeds in a Snap Bean Agroecosystem
(2004)Abstract.Integrated weed management strategies maintain sub-threshold levels of weeds. The remaining weeds may impact the feeding and habitation patterns of both potato leafhoppers and bean leaf beetles in a snap bean ... -
Influence of soil moisture levels and packaging on post harvest qualities of tomato
(2015-03-11)Preharvest factors influence postharvest quality of tomatoes. Whereas water stress improves fruit total soluble solids; and polyethylene is used for packaging of fresh horticultural produce, little is known about their ... -
Interactive effects of packaging and storage temperatures on the shelf-life of okra
(ARPN Journal of Agricultural and Biological Science, 2009-05)A study aimed at evaluating the potential benefits of pre-packaging and storage temperature in extending the shelf life of okra was conducted at Egerton University Horticulture Field and Biotechnology Laboratory. Okra ... -
Effects of cowpea leaf harvesting initiation time on yields and profitability of a dual purpose sole cowpea and cowpea maize intercrop
(2010)Harvesting of cowpea leaves for use as leaf vegetable has gained prominence in many parts of Africa and Asia. Little is known on effects of leaf harvesting on leaf and grain yields and profitability of cowpea-based ... -
Improving Carrot Yield and Quality through the Use of Bio-slurry Manure
(Canadian Center of Science and Education, 2012-11-25)Continuous cultivation of farms has led to decline in soil fertility due to constant removal of nutrients leading to reduction of carrot (Daucus carota L.) yields. A field study was carried out at Egerton University, ... -
Interference of large crabgrass (Digitaria sanguinalis) with snap beans
(Cambridge University Press on behalf of the Weed Science Society of America, 2003)Field experiments were conducted to determine the effect of large crabgrass densities of 0.5 to 8 plants m-1 of row and emergence time on snap bean yield. Large crabgrass was planted either along with snap beans (early) ... -
Use of soil streptomycetes from Maseno (Kenya) to inhibit growth of Pyricularia grisea invitro cultures.
(IOSR Journal of Agriculture and Veterinary Science (IOSR-JAVS), 2013)The most serious biotic constraint to finger millet worldwide is blast caused by the fungus Pyricularia grisea. Its management has been very challenging. However not a formidable control solution has been offered and ... -
Pre- and post harvest factors affecting sorghum production (Sorghum bicolor L. Moench) among smallholder farming communities
(International Journal of Agronomy and Agricultural Research (IJAAR), 2014)A farm survey was conducted on Sorghum (Sorghum bicolor L. Moench) as a staple cereal crop adapted in arid and semi – arid lands. The objective was to determine pre - and post - harvest factors affecting sorghum production. ... -
Occurrence and estimated losses caused by cassava viruses in Migori County, Kenya
(African Journal of Agricultural Research, 2016)A farm survey was conducted in Kuria East and Suna West sub-counties to determine the incidence, severity and estimated losses of cassava brown streak disease (CBSD) and cassava mosaic disease (CMD) on cassava crops in ... -
Harvesting surface rainwater – purification using Moringa oleifera seed extracts and aluminum sulfate
(Journal of Agricultural Extension and Rural Development, 2011)Ground water harvesting is a method of collecting surface runoff from a catchment’s area and storing it in surface reservoirs. The water harvested is usually contaminated and turbid. Methods used to purify water include ... -
