Effect Of Withholding Irrigation Water After Complete Heading On Rice Yield And Seed Quality In Mwea, Kirinyaga County-Kenya

ABSTRACTRice 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, resultin...

Socio-Economic Factors Affecting Technical Efficiency Of Small Holders Maize Production In Rwanda

ABSTRACT Maize is still largely a subsistence food crop under promotion as a food security crop and source of income for smallholders. In a bid to attain self-sufficiency, Rwanda made remarkable efforts to develop the subsector. These were mainly directed towards the expansion of the area under maize, organisation of farmers’ cooperatives and easy access to inputs. In improving maize productivity and marketing of maize several both public and private interventions were added in Musanz...

Assessment Of Water Quality Status Of River Kibisi, Kenya Using The Ephemeroptera, Plecoptera And Trichoptera (Ept) Index

AbstractThe term water quality is applied universally to refer to the water status that meets the universal standards set for legitimate and vital water use at any scale i.e. local, regional and international levels (WHO, 2000). The evolution of the term water quality has been due to the expansion of water requirements and ability to measure and interpret water characteristics. The definition of water quality depends on the factors that determine it, and other variables that affect the na...

Seasonal Abundance Of Amaranth Lepidopteran Defoliators And The Role Of Indigenous Parasitoids And Phenylacetaldehyde In Their Control In Nairobi County, Kenya

ABSTRACT Amaranth is one of the African indigenous vegetables that is gaining popularity due to its nutritional, medicinal and economic values. Its potential as a source of food security in East Africa and most parts of the world has heightened demands for the once neglected crop. In Kenya and Tanzania, the Lepidopteran defoliators are important pests of the crop which can cause up to 100% yield loss. Little information on the population dynamics of these pests make their management di...

Effects Of Phosphate Rates On Nitrogen Uptake, Growth, Yield And Quality Of Finger Millet In Busia, Kakamega And Makueni Counties

ABSTRACTFinger millet (Eleusine coracana) is an important subsistence cereal grain grown mainly in the relatively marginal and dry areas of Kenya. The crop has particular relevance in food security as it is more resilient to abiotic and biotic stresses than other cereals and even fetches higher prices in the market. It provides valuable sources of minerals and nutrients and is recommended for pregnant and nursing mothers and infants. However, productions of the crop both in hectareage and yie...

Impact Of Habitat Moderation By Weir Installation On Invertebrate And Fish Communities In Rivers Awach–Seme (Kenya) And Nambale (Uganda

ABSTRACTThe Lake Victoria Basin (LVB) rivers and streams once rich in biodiversity have been undergoing degradation over the years resulting in decline in fish productivity. Studies have mainly focused on large rivers in Kenya and Uganda. Impacts of habitat alteration by weir installation as a river management tool are lacking.
