Cocoa (Theobroma cacao) contributes significantly to Ghana’s GDP and has made Ghana a recognized leader in the cocoa industry. However, there are myriad problems associated with Ghana’s cocoa bean quality. One such problems stems from farmers paying less attention to the required postharvest activities (fermentation and drying) which contributes significantly to bean quality losses. *is study investigated the effect of the duration of the traditional heap fermentation period and differ...
Under rain-fed conditions, perfumed rice production in Northern Ghana is associated with high paddy cracking during milling. In this study, 4 perfumed rice varieties, 6 staggered planting times, 6 staggered harvesting cycles, and staggered storage duration from harvest to six months of storage were used in a randomized complete block design to identify the best combination of factors that are associated with low cracking in rice production. )e experiment was laid out in a randomized comple...
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. Thetreatments 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 nema...

Decline in yields and frequent failure of major crops in Embu and Kiambu counties, Kenya, is linked to inadequate or unevenly distributed rainfall and poor agronomic practices, among other factors. The main objective of this study was to evaluate the effect of using mulch and hydrogel in production of yellow passion fruit in Embu and Kiambu Counties, Kenya. The study was set up specifically to (i) determine the effect of mulch and hydrogel on soil moisture and nutrients in a yellow pass...
ABSTRACT Rice is relatively new to Uganda, yet consumption is outstripping production; and with a growing population, demand is likely to increase. NERICA (New Rice for Africa) rice – with high yields and ability to withstand dry conditions is being planted in most part of the country. However, weed infestation is becoming one of the biggest hindrances affecting rice production. The objective of the current work was therefore to investigate the effects of varietal differences, plant spacin...
ABSTRACT Green pepper (Capsicum annuum) is one of the most important and remunerative vegetable crops. Row spacing and mulching are important factors that influence water use, weed suppression, growth, quality, and yield of vegetables. Due to increased pressure on land, climate change and increased demand for vegetables, there is need for deployment of optimal agronomical practices that will ensure enough food production. This study was undertaken to determine the optimum spacing and mulching...
ABSTRACT Drought is a major abiotic factor limiting crop productivity in many regions of the world. It causes reduction in plant growth, dry matter accumulation and decline in plant water status of the plants and in certain cases interferes with biochemical processes within cultivated crops. The aim of the study was to map out the distribution of different African Nightshade species in Siaya and Kisii Counties of Kenya and to determine water stress effect on total antioxidant capacity and tot...
ABSTRACT Ultraviolet (UVB) radiation (280–315 nm) and interaction with Selenium (Se) have potential promoting plant tolerance to UVB stress in plants and modify metabolites that influence taste and functional properties of tea. The objectives of this study were to assess sensitivity of two tea varieties to ambient solar UVB radiation and Selenium nutrition on 1) yield components,2) secondary metabolites, antioxidant activity, theanine and mineral composition of tea and 3) non-aerated (gree...
Rice is a staple food and the main source of calories and proteins for more than half of the world population. Its increasing demand in Africa made it a commodity for food security and poverty reduction. Rice ranks third in Kenya’s staple food after maize and wheat. Its consumption has been growing rapidly due to urbanization and changing eating habits in both rural and urban households. In 2014, local rice production was estimated at 129,000 metric tonnes, while consumption was 548,00...
ABSTRACT Rice 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, resulti...
ABSTRACT Finger 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 yi...
ABSTRACT Inoculation of soybean (Glycine max) is an efficient and convenient way of introducing rhizobia to soil and subsequently the rhizosphere of the crop. However, its full potential in sub-Saharan Africa is yet to be realized due to effects of varying soil limiting conditions. Critical levels of nitrogen (N) below and above which response is not guaranteed are unknown. The objective of the study was to determine the critical range of N outside which response to inoculation is hindered. ...
ABSTRACT Sweet yellow passion fruit (Passiflora edulis var. flavicarpa) is widely gaining adoption in Kenya, emerging as an important high market value horticultural crop. However, its current yields are low due to poor agronomic practices among other reasons. The objectives of this study were to determine the effect of vine length on growth, yield and nutrient concentration of sweet yellow passion fruits in Embu County and evaluating orchard management practices for sweet yellow passion frui...
ABSTRACT African Indigenous Vegetables form an integral part of the Kenyan diets, among the most commonly consumed being the African nightshade. These vegetables contain important phenolics that have medicinal values and good health attributes. The abundance of these phenolic substances has strongly been associated with phosphorus use efficiency. In order to investigate the effect of phosphorus stress on African nightshade distribution, a purposive research was done from February 2014 on 70 ...
