“…For example, the total domestic rice demand in Nigeria is estimated at about 3.69 million metric tons while production was only 2.3 million metric tons with import of 1.39 million metric tons in 2004/2005. This amounts to a shortfall of 1.39 million metric tons to satisfy domestic requirement (Oyekanmi et al 2008).…”

The physical and water absorption characteristics of paddy and brown rice from some early maturing Oryza sativa varieties and newly developed interspecific (O. sativa × Oryza glaberrima) rice varieties were studied. The physical dimensions (length, breadth and width, length/ width ratio, equivalent diameter), grain surface area and volume, sphericity, 1,000-kernel weight, bulk and true densities as well as porosity were determined. A nonlinear moisture diffusion equation was used to model the water absorption curves of the rice varieties at 30-60°C. Digital images of the rice grains were analyzed for their tristimulus color parameters (L*, a*, b*). The physical characteristics of the rice varieties differed significantly (p<0.05). The rice grains were of medium size with length/width ratio ranging between 2.80 and 3.50. Notably, the New Rice for Africa variety WAB 450 aka NERICA 1 had the smallest 1,000-kernel weight and the highest husk/paddy weight ratio. The equilibrium moisture content was significantly influenced (p<0.01) by the soaking temperature and the rice component being soaked. The hydration rate curves were generally characterized by two falling rate periods. The predicted water absorption curves were very close to experimental curves (0.91

“…In assessing vegetable quality, external and visible characteristics such as damage-free fruit, freshness, size, and color are valued (Bosland and Votava 2000;Coulibaly, 2011;IPGRI, 1995;Ghana Standards Board, 2004;Okeyele et al, 2006;Oyekanmi et al, 2008). A visual assessment of dried fruit quality and perceived market preference based on those criteria was carried out in the last season at three workshops, each involving more than 80 male and female pepper farmers and processors from pepper farming areas in three northern regions of Ghana.…”

Production of Bird's eye chillies (Capsicum annuum L) under tropical conditions presents a unique opportunity for small farmers to improve income. A study in 2010 and 2011 evaluated the performance of irrigated, improved Bird's eye chilli (BEC), cvs. Demon, UHP281 70, UHP226 94, and UHP296 92, with 'Shito Adope', for growth, adaptability, yield, and marketability. The cultivars are categorized as being early ('UHP281 70' and 'Shito Adope'), medium ('UHP226 94' and 'Demon'), and late maturing ('UHP296 92'). The UHP series had the best yield (average 12.47 Mt·ha −1 ). The best choice for crop performance and dried fruit quality/brightness and perceived marketability was 'UHP281 70' followed by 'UHP226 94'. Economic analysis indicated that 'UHP296 92' had the highest total variable cost. It also had the highest marginal rate of returns (217%). It is possible to increase options for small-, medium-, and large-scale chilli pepper farmers regarding choice of superior Bird's eye chilli peppers.
