    Effective team building in the shea butter industry – a case of Tolon district
    (KNUST, 2019-11) Mohammed, Haruna
    Team building involves a wide range of activities, designed for improving team performance. This study has reviewed literature on teams in an attempt to outline some of the key issues within the Shea Butter groups so as to give a realistic view of what can be achieved through teamwork by ensuring successful team-building efforts within the industry. The reviewed literature indicates that the effects of teamwork are contingent upon many factors, including the group’s culture and environment. This study also outlined some key points that have been identified by a number of respondents which could facilitate the effective development of teams. These points are: clear goals or good game plan; decision making authority; accountability and responsibility; effective leadership; training and development; avoidance of group think; encouraging team diversity; effective communication and trust. This study seeks to build effective Shea Butter Teams to improve on the economic lives of the rural woman in Tolon District, using both quantitative data from individual group questionnaire and qualitative data from focus group discussions and key interviews. In order to control selection bias, the study utilized a reasonable sampled groups using statistical tools covering; age, gender, position and educational status which may affect the success of the team’s efforts. Furthermore, the recommendations of the study suggest groups to develop goals and plans, enhance communication among members, develop and maintain positive relationships among members, solve problems and make decisions on a timely basis, successfully manage conflict, facilitate productive meetings, clarify roles for team members, operate in a productive manner, exhibit effective team leadership and provide development opportunities for team members. All these were aimed at bringing out the best in a team to ensure self-development and the ability to work closely together as a team to solve problems and improve productivity

    Genetic Analysis of Resistance to Pod Shattering in Soybean (Glycine Max. (L) Merrill).
    (April, 2010) Mohammed, Haruna
    Genetic analysis of resistance to pod shattering was undertaken on three soybean crosses with reciprocals involving resistant and susceptible varieties to examine broad sense (h2bs) and narrow sense (h2ns) heritability, minimum number of genes involved (MNG), mid-parent heterosis (MPH), cytoplasmic inheritance and allelic relationship between shattering and non-shattering. Two sets of experiments were conducted. The first experiment was a non-replicated crossing block in plastic pots to develop F1 populations at the plant house of the Faculty of Agriculture – Kwame Nkrumah University of Science and Technology, Kumasi (Latitude 06o 41′ N and longitude 01o 33′ W). F1 plants were selfed to produce F2 generations. The F1 progenies were backcrossed to both parents to produce BC1 and BC2 progenies. The second experiment was a replicated trial laid in a randomized complete block with three replications to determine genetic ratios for levels of pod shattering resistance at F2 and this was used to determine allelic relationship between shattering and non-shattering genes using chi-square test. Mean h2bs was 0.30 (range 0.00 – 0.90) and mean h2ns was 0.92 (range 0.00 – 1.72) indicating the importance of both additive and non additive variances, suggesting that improvement in resistance can be achieved through breeding. Mean MNG was two genes (range 1 – 3) indicating that genes for resistance differed among parental lines. Mean MPH was -3.7% (range -44.1 – 55.7%) indicating that heterosis did not influence the expression of resistance to pod shattering in soybean. There was no difference between the mean of any F1 population and it’s reciprocal, indicating lack of maternal influence and that the character could be under nuclear gene control. Observed ratios at F2 population revealed that, inheritance of resistance to pod shattering is quantitative and under the influence of either duplicate recessive or dominant and recessive epistasis depending on the parental genotypes used in the cross.
