Item The market factor in the processing of tomato (Lycopersicon esculentum) in Ghana(Journal of Food, Agriculture and Environment, 2007-07) Aggey, M.; Amoah, Y.; Bani, R.J.Local industrial tomato processing in Ghana remains insignificant in the mist of perennial tomato glut in the Upper East region of Ghana. A basis for processing decision making has been provided using exploratory research techniques to review tomato consumption, market segmentation and structure, production surpluses, prices and buying process of fresh and paste tomato. Fresh tomato surplus projects at 23,000 to 118,000 t p a (2000-2007) though actual glut period is short, occurring from February to March when 92 percent of farmers harvest, and traders use hedging tactics to avoid tomato spoiling on their hand. With the short glut period, large-scale processing requires planning and investment in semi-processed or cold storage facility, integrated project with cultivation of tomato variety suitable for harsh lean season climatic conditions and production staggering to prolong harvesting. Projected paste from surplus produce exceeds catchments area market, yet access is in competition with established brands such as Salsa, La bianca, Bonito, Tomaroma and Obaapa. Processing could target a paste market of 2,000-3,0001, requiring 16,470 t fresh tomato, at a processing capacity of 2.3 t per hour, 24 hour-day and for 300 days p a, with plans for future expansion. This study was conducted in the last quarter of 2002.Item Prediction of surface area of garden egg (Solanum Aethiopicum L) from weight measurements(AMA, Agricultural Mechanization in Asia, Africa and Latin America, 2009-09) Bani, R.J.; Kra, E.Y.; Amoah, J.; Aggey, M.Estimation of surface area of various agricultural produce can have a wide range of applications for both producers and processors. The methods available are tedious and in certain cases destructives Studies have been conducted with respect to predicting the surface area of some fruits and vegetables such as apples and tomatoes. Very few, if any, similar attempts have been made to estimate the surface area of indigenous African crops. The objective of this study was to develop a model that will predict the surface area of the garden egg (Solanum aethiopicum L) from weight measurements. It is easier to measure the weight of the garden egg than to measure its surface area. Weight and surface area measurements of each garden egg were used to develop equations to predict fruit surface area (cm2) from the raw weight. The linearregression model developed showed strong correlation between surface area and weight measurement and can be used to estimate the surface area of garden egg. For a garden egg weighting 47.4 gm, the model predicts its surface area between 96.3 and 118.5 mm2 with 95 % confidence.
