ABSTRACT The influence of inorganic N sources on growth, leaf yield and quality of mulberry (Morus alba) was studied under field conditions before (Experiment 1) and after (experiment 2) pruning. The treatments consisted of three mulberry varieties (Kanva-2, S-36 and Mysore local) and three N sources (urea, Sulphate of Ammonia and NPK) and a control. The experimental design used was a split plot design. Varieties formed the main plot and N sources the sub-plot factors. The N sources had signi...
ABTSRACT Soil salinity is one of the most important factors retarding rice growth and development at both vegetative and reproductive stages. This is becoming a major challenge in the production of rice in Ghana and Africa as a whole. This has necessitated the breeding of salt tolerant lines for the future, since population and hence consumption of rice is always on the increase. Thirty-two (32) rice accessions including four (4) checks were screened for salinity tolerance and also used in di...
ABSTRACT Soybean is afected by a wide range of diseases, many of which are seed-borne. Infection by seed-borne pathogens leads to seed rot, low seedling vigour and reduction in plant growth. Seed-borne fungal pathogens on farmer-saved seeds of soybeans were investigated by examining a total of eleven (11) seed samples from two districts (Saboba and Yendi) in the Northern region and one from CSIR-Savanna Agricultural Research Institute (CSIR-SARI). Appearance quality of farmer-saved soybean se...
ABSTRACT The experiments were conducted in 2013 cropping season at the University of Education Winneba, Faculty of Agriculture research field in Mampong Ashanti in the forest transitional zone of Ghana on the Bediase series (FAO/ UNESCO : Chromic Iuvisol) to evaluate the effectiveness of three livestock manures and soil in acidulating Togo rock phosphate to release phosphorus, assess phosphorus release capacity of phosphate rock – animal manure compost on the growth of lettuce and soil chem...
ABSTRACT A significant quantity of yam tubers gets deteriorated in storage due to sprouting, weight loss, and rotting. There was, therefore, the need to identify cost effective ways of extending postharvest life of yam tubers without compromising with the health of consumers. Therefore, field research was conducted to explore the effect of shea butter & palm kernel oil waxing, yam variety, and tuber size on postharvest shelf life of Puna, Asana, and Punjo varieties of white yam (Dioscorea rot...
ABSTRACT Concerns have been expressed by pesticide management specialists about the choice and use of insecticides in cabbage production and fear o f toxic residues on harvested cabbage head. This investigation involves a survey to determine cabbage fanners’ insecticide use patterns and analysis for insecticide residues on samples o f cabbage. The survey revealed that cabbage growers in the Accra-Tema Metropolitan area o f Ghana invariably relied on insecticide retailers/agents for advice o...
ABSTRACT Pot and field studies were carried out at the University of Ghana, Legon, to evaluate the effect of Bradyrhizobium japonicum inoculation and five rates of phosphorus application on growth, nodulation and dry matter production of some promiscuous and non-promiscuous soybean cultivars in pots and finally the effect of three rates of phosphorus and inoculation on growth, nodulation, dry matter production and yield of a promiscuous cultivar "Bengbie" in the field. In the pot experiment, ...
ABSTRACT Maize (corn) is one of the most crucial and strategic cereal crops in Africa. Production occurs in all ten regions of Ghana. Despite significant improvement in food storage methods, many communities in Ghana still use traditional storage practices and structures for keeping food and seed. This has led to short falls in maize supply due to high losses and poor quality. Thus the need to determine the effect of traditional practices and storage structures on the quality of maize stored....
ABSTRACT Three experiments were conducted during the dry season from October 2001 to April 2002 at the University of Ghana Farms and the Food Research Institute, to evaluate two methods of conservation of sweet potato planting material and one method of multiplication of vines were evaluated in this study using two cultivars - Sauti and Okumkom released to farmers by the Crops Research Institute. The study was aimed at developing a technology to ensure the availability of adequate quanti...
ABSTRACT The study investigated the occurrence of high purple beans counts of cocoa produced in Ghana. The investigation consisted of a questionnaire survey of nineteen randomly selected districts in the six cocoa growing regions in Ghana and laboratory studies at the Cocoa Research Institute of Ghana. The studies were carried out from August 2005 to October 2006. Fermentation of cocoa beans for six or seven days did not guarantee the complete removal of anthocyanins and purpleness from the ...
ABSTRACT The research was conducted to investigate the effects of High Yield Technology (HYT) biofertilizers, biochar and inorganic fertilizer on the growth and yield of pepper. The studies were conducted at the University of Ghana Forest and Horticultural Crops Research Centre (FOHCREC), Kade from May 2011 to April 2012. The experiment consisted of three factors namely, HYT, Biochar and inorganic fertilizer at three levels each (HYT: 100%, 50% and 0%); Biochar: 7t/ha, 3.5t/ha and 0t/ha; inor...
ABSTRACT Cultural practices as management strategy for beanfly control were examined over four cropping seasons in 1991 and 1992 under f a r m e r’s developed field conditions at Oyugis, in Homa Bay District of Western Kenya. In many parts of East and Central Africa, the beanfly is a major constraint to the production of the bean crop (Phaseolus vulgari s ), Its incidence causes yield losses averaging 47-87%, Control methods used against the pest are mostly insecticides based. Cultural cont...
ABSTRACT Coconut (Cocos nucifera L.) is an important cash crop in the economy of the people living in the coastal belt of Ghana, specifically Jomoro district in the Western region. Coconut oil is essential for its unique nutritional and economic purposes; which contain medium chain fatty acid and used for pharmaceutical purposes. The quality of coconut oil produced by the small-scale processors cannot be ascertained, as quality control measures and oil recovery cannot be strictly assured. The...
Abstract The effect of three different moisture and shade regimes on the seedling growth of three Dura x Pisifera oil palm progenies was investigated at the Oil Palm Research Institute, Kusi between July 1998 and February 2000. A split plot design with four replications was used. Data were collected on leaf number per plant, plant height, butt circumference and leaf area as well as dry weight of plant parts and total plant dry weight. Growth analysis was performed and correlation among traits...
ABSTRACT This study was conducted to identify some agronomic characters of maize plants which make them suitable for use in cassava/maize intercropping systems. The feasibility of intercropping cassava with high maize populations was also studied. A strip-split plot design with a parallel-row systematic arrangement in which five maize varieties, IK.84A-2135, IB84A-203 , TZSR-Y-1, 1368 x 5012 and 9450 x 4001 at five population densities of 10,000, 20,000, 40,000, 80,000 and 160.000 plants/ha i...
