In Vivo Stimulation of Axillary Bud Initiation, Growth and Development of Plantain (Musa Aab.) Using Coconut Water and Indole-3-acetic Acid ABSTRACT   The study was carried out at the University of Ghana Forest and Horticultural Crops Research Centre (FOHCREC), Kade from 2008 to 2012. Two experiments were conducted to investigate the effects of coconut water (CW) alone or in combination with varying concentrations of auxin (IAA) on axillary bud initiation, growth and development of plantain (cv. Asamienu). In the first experiment, coconut water from fully matured dried fruits was supplemented with three different IAA concentrations, 10-4 M, 10-3 M, and 10-2 M to produce five different coconut water : IAA ratios (v:v), viz: 8:0, 6:2, 4:4, 2:6, 0:8. Three weeks after the injection treatments, variations were seen in the rate of axillary bud...

Evaluation of Hybrid Maize Varieties in Three Agro- Ecological Zones in Ghana ABSTRACT   Maize (Zea mays L.) is an important food crop in Ghana, but its productivity in farmers‟ fields throughout the country is generally low. The low grain yields can be attributed partly to the use of traditional low-yielding maize varieties. Farmers‟ adoption of hybrid varieties would reduce deficit of demand and supply of maize in the country. A study was undertaken to assess the relative yielding abilities and stability of 20 hybrids selected from the breeding programme of the West Africa Centre for Crop Improvement maize breeding program together with three locally released varieties. The trial was conducted in the coastal, savannah and transitional forest zones over major and minor seasons in 2012 and 2013. A randomized complete block design with...

Knowledge Gaps, Training Needs and Bio-ecological Studies on Fruit-infesting Flies (Diptera: Tephritidae) in Northern Ghana ABSTRACT   Tephritid fruit flies are a major threat to the horticultural industry in sub-Saharan Africa owing to the heavy losses they cause to fruit and vegetable crops, and the resultant quarantine restrictions. Addressing the fruit fly menace in Ghana requires effective stakeholder training along the fruit value chain, coupled with adequate research information on management strategies. Baseline studies were conducted in northern Ghana to determine the priority management training needs of fruit growers and Agricultural Extension Agents (AEAs), and to document the host range, species composition, seasonal phenology and parasitoid fauna of the pests. The studies involved the use of questionnaire for surveys coupled...

Studies on Oil Palm Based Cropping Systems in Ghana ABSTRACT A survey was conducted in 1994 to gather information on the practice of intercropping food crops in oil palm on small-scale farms in the oil palm zones of southern Ghana.   The objective was to identify and study intercropping systems used in oil palm production. Data was collected by interviewing a tOtal Of 72 oil palm farmers from the oil palm growingregions,(Eastern, Central,Western,Ashanti,Brong-Ahafo,and Volta) at their farm locations.       The responses indicated that the small-scale oil palm farmers in Ghana commonly intercrop oil palm with maize, cassava and plantain especially during the first three years of the crop. The three staple crops, maize, cassava and plantain were intercropped in oil palm between 1994 and 1997 at the Oil Palm Research Institute, Kusi, Ghana...

Analysis of the Impact of Physical and Social Capital Asset Holdings on Poverty Among Farm Households in Nigeria   ABSTRACT The study was conducted to analyze the impact of physical and social capital asset holdings on poverty among farm households in Nigeria as a contribution towards finding a panacea to the poverty plague in the agricultural sector. The study used secondary data obtained from the Nigeria living Standard Survey data conducted in 2003/2004. Data were analyzed using descriptive statistics, Forster-Greer-Thorbeck poverty measures and Propensity score matching. Results showed that 90% of the households were headed by males, 54% had household sizes of 1-4 and 79% were within the active productive age of less than 60 years while 62% had no formal education. About 96% were married whereas only 18.83% of the married...

Genetic Studies of Physiological and Morphological Traits Associated With Drought Tolerance in Cassava Genotypes ABSTRACT   This study was undertaken to identify key traits that are closely related to cassava yield under drought stress and also identify stable high yielding cassava genotypes under varying environments. A survey was conducted using in semi-structured questionnaire in three districts in the Northern Region involving 120 farmers to identify farmers’ perception on drought in cassava cultivation, production constraints, mitigation strategies and preferences for improved cassava genotypes. To identify ideal genotypes that meet farmers’ preferences, 150 cassava genotypes from local and exotic sources were assembled and assessed for diversity using morphological traits and simple sequence repeat markers. Subsequently 20...

Genetic Analysis of Drought Tolerance in Cowpea [vigna Unguiculata (L.) Walp] ABSTRACT   Agriculture in Sub Saharan Africa (SSA) is under serious threat due to water shortage, population pressure and climate change. Cowpea, a protein-rich legume crop complements staple cereal and tuber crops in the diets of rural and urban people of the tropical and sub- tropical regions of the world. It therefore, plays a significant role in the sustainability of food and nutrition security in SSA. Cowpea, though reported to be inherently drought tolerant; but because it is mostly grown under rain-fed conditions towards the end of the rainy season in the drier parts of Nigeria, its productivity is still being adversely affected by the erratic pattern of rainfall which occurs frequently in these areas. Increasing the level of drought tolerance in existing...
