    The growth of the winged bean (psophocarpus tetragonolobus (L) DC)
    (1984) Asare, Eric
    TWO experiments were conducted at the Arable Crops Section of the University of Science and Technology farms, Kumasi, (6° 43’N, 10 36’W) in 1981 and 1982, to study the influence of date of sowing, plant population density and 50% flower/pod removal on the growth and yield of two winged bean cultivars. Shoot and seed yields and components in the two cultivars (Tpt-8 and Tpt-1) were affected by the date of sowing, being positively influenced by rainfall and solar radiation income, so that major season planting (May sowing) gave higher shoot and seed yields than the minor season planting done in September. Both cultivars produced the highest seed yield at a population density of 2.7 plants/m2, irrespective of the date of sowing. Thus, a density of 2.7 plants/m2 appeared to approach the optimum for the crop under the conditions of the experiment. Seed yield was found to be mainly influenced by the total number of pods produced, although as plant density increased, the other components, that is, the number of seeds per pod and the mean weight per seed, also declined. 50% deflowering did not influence seed yield in the cultivars used, although normal plants appeared they have produced a higher seed yield and components. Deflowered plants generally gave greater roots and tuber weights than normal plants.

    Modelling Cocoa Farmer Behaviour Concerning the Chemical Control of Capsid in the Sekyere Area Ashanti Region, Ghana
    (2011-10-05) Asare, Eric
    This paper modelled the behaviour of the cocoa farmer in the Sekyere Area (Sekyere West, Afigya Sekyere and Sekyere Central), Ashanti Region, Ghana, concerning the chemical control of capsid. This was done by identifying the factors that determined the use of capsicide as well as the frequency of spray of capsicide (twice or more). It also quantified the effect of the factors on the use of capsicide and the frequency of spray of capsicide (twice or more) using a Tobit model and a Probit model respectively. A simultaneous Bi-Probit model was also employed to quantify the simultaneous effect of the factors that determined the frequency of use and quantity of use of capsicide. It was shown in the study that access to credit, household size and membership of a farmers’ group had statistically significant and highly probable influence on the cocoa farmer to spray twice or more. Also, access to credit, farmer’s experience, engagement in other economic activities, membership of farmers’ group and input shop availability were significant and had the same effect on the likelihood of the farmer using capsicide.
