Determination Of Levels Of Some Vitamins In Amaranthus Hypochondriacus And Amaranthus Cruenthus Leaves And Grains From Selected Areas Of Kenya

Vitamin deficiencies are health hazards in some parts of Kenya. These are attributed to inadequate access to vitamin-rich foods occasioned by decline in agricultural production due to unfavourable climatic conditions, low purchasing power due to poverty, over reliance on staple foods and dependence on highly refined foods, which are poor in vitamins. Higher intake of vitamin-rich vegetables and grains can alleviate this problem. Grain amaranth (GA), which is relatively a new crop in Kenya, is...

Growth, Yield And Fruit Quality Of Select Vegetables (Tomato, Green Pepper And Garden Eggs) As Affected By “Asase Gyefo” Premium Organic Fertilizer

ABSTRACT Declining soil fertility has been found to be the main cause of reduction in crop yields. These soils lose their fertility through erosion, leaching and crop removal. Organic fertilizers prepared from human waste has been found to have a greater potential of being used to manage soil fertility and hence increase crop yields. The present study is to determine the nutrients content and effect of Asase Gyefo Organic Fertilizer (AGOF) prepared from human waste on the growth, yield and sh...
