What factors influence performance of farmer groups? A review of literature on parameters that measure group performance

Farmers form and participate in groups in order to benefit socially and economically through collective activities. However, membership in groups alone is not enough to facilitate improvement of livelihoods, owing to the fact that only successful groups would be able to fully exploit their potential and meet the interests of their members. Understanding group performance is therefore a pertinent issue among social...

An on-farm comparison of the agronomics and economics of irrigated maize production systems in the Somali Deyr season

Domestic production only supplies half of Somalia’s cereal requirements and more than half of the country’s population is considered food insecure.  In this study, the Somali Agriculture Technical Group (SATG) used an on-farm participatory research approach to compare the economic viability and plant yield parameters of an improved maize production system (SATG system) with those of the traditional...

The effect of velvet bean (Mucuna cinerea) extract on seedling growth of winter cereals

Some plants can have a beneficial or harmful effect on the germination and growth of other plants. This is known as the allelopathic effect. The objective of this study was to evaluate the effect of different doses of velvet bean (Mucuna cineruim) aqueous extract on germination and initial seedling growth of three winter cereals: white oat (Avena sativa), rye (Secale cereale) and wheat (Triticum aestivum). The...

Response of taro (Colocasia esculenyta (L.)) to variation in planting density and planting dates on growth, radiation interception, corm and cormels yield in Southern Ethiopia

Taro production is mainly affected by agroecology, planting time and planting density.  To this effect, a field study was conducted to determine influences of planting density and planting dates on growth, radiation interception and yields of taro (Colocasia esculenyta (L.)). The experiment was conducted using four levels of planting density (15037, 19607, 26666 and 38461 plants ha-1) and four planting dates from...

Climate analysis for agricultural improvement of the Economic Community of West African States according to Köppen and Thornthwaite

The Economic Community of West African States (also known as ECOWAS from its name in French: Union Économique et Monétaire Ouest-Africaine) is composed of eight countries: Benin, Burkina Faso, Ivory Coast, Guinea-Bissau, Mali, Niger, Senegal and Togo. This study is restricted to ECOWAS because it stems from a survey mission headed by the second author and aims to characterize the climate of the territory...

Estimation of amylose, protein and moisture content stability of rice in multi locations

Rice quality is measured of the rice grown on different five locations by an auto grain analyzer. Auto Grain analyzer works on the Near-Infrared transmittance (720 - 1100 nm). Protein, amylose and moisture contents of the rice samples of 9 fine lines were tested. Different environment tested entries were evaluated and found that all the values have highly significant effect of environment and genotypes. The environment...

An agronomic approach to screen sugar and energy cane genotypes for drought tolerance

Sugarcane production can be affected by extreme environmental conditions, such as drought stress. This study focused on establishing a screening method to evaluate and select drought tolerant germplasm of Saccharum species. A new drought screening methodology is presented in this paper. A randomized block design experiment was conducted under greenhouse conditions with 2 months old seedlings of five genotypes of...
