Effects of a brief, intense infrared radiation treatment on the nutritional quality of maize, rice, sorghum, and beans

Maize, sorghum, rice, and beans were subjected to a temperature of 22,000°C for 0.5 minute in an infrared radiator 3 m long. The uncharred grains exited the radiator at a temperature of 140° C and were cooled to room temperature. The moisture content dropped to 3% to 7%, thus affecting the proximate composition of the grain components. The digestibility of cereal starch remained high and unchanged (71%-84%), whereas protein digestibility was reduced by 7%, 21%, and 25% in rice, sorghum, and maize, respectively. The caloric values of the cereals remained unaltered.

Evaluation of crop cover and residue management C factors for cropping systems and management techniquesin the semi-arid region of Kenya

The mean crop cover and residue management C factor for maize with conventional tillage, maize with minimum tillage, maize intercropped with beans on alternate rows, beans alone, and maize with 3 t ha -1 of maize residue were0.77,0.45,0.44,0.3O and 0.15 respectively, as measured in two groups of subsequent rainy seasons. The high C factor for maize with conventional tillage was aitributed to low planting density for maize and slow groundlover development that provided very minimal soil protection against raindrop impact.

The Influence Of Agricultural Technologies On Food Security Among Households In Nakuru District, Kenya

The Kenya Vision 2030 is a vehicle for accelerating transformation of Kenya into a rapidly Industrializing middle-income nation by the year 2030.The Vision 2030 recognizes the role of science, technology and innovation in a modern `economy, in which new knowledge plays a central role in wealth creation, social welfare and international competitiveness. It is reported that fifteen million (approx. 50 %) of Kenyans are food insecure with three million supplied with food relief throughout the year (Kaloi etal, 2005).

Determinants Of Household Vulnerability To Food Insecurity: A Case Study Of Semi‐arid Districts In Malawi

This paper looks at household vulnerability to food insecurity and its determinants in two semi-arid districts in Malawi. A randomly selected sample of 200 households was interviewed. The descriptive statistics revealed that female-headed households were more vulnerable to food insecurity than male-headed households because of low access to resources for food production and purchases. A two-stage least squares regression analysis showed that amongst the main determinants of household vulnerability were income, household size, land size and access to climate information.

Analysis of the Effect of Land Tenure on Technical Efficiency in Smallholder Crop Production in Kenya

Agriculture is the backbone of the Kenyan economy contributing 26% to GDP and 70% to employment. Majority of the farmers in Kenya are smallholder farmers possessing less than 3 acres of land. The agricultural sector in Kenya has been facing several challenges among them declining yields. While the decline in yields could be associated with several other factors, it could also be as a result of the effect of insecure land tenure systems which are little understood.

Helminthosporium maydis on maize

A severe outbreak of leaf blight on maize in Apr. 1978 in the Nyanza Province, Kenya, was caused by H. maydis [Cochliobolus heterostrophus: CMI Map 346], a previously unrecorded disease

Diversity of nematodes and nematode destroying fungi as influenced by land use in Taita Taveta, Kenya

Land intensification is thought to lead to soil degradation and consequently to loss of soil biodiversity. A study was undertaken to assess the effect of land use on nematode community and nematode destroying fungi in Taita districts, Kenya. Soil samples were collected from land under various uses which were natural forest, plantation forest, tea, coffee, napier grass, fallow, maize/beans intercrop and horticultural crops production. Chemical analysis of the soil properties was done to determine the amount of carbon, nitrogen and potassium in every land use system.

Agroeconomic performance of Aguthi, Matanya and Thome smallholder irrigation schemes

The key objectives of smallholder irrigation projects are increasing agricultural production, household incomes, employment generation and ensuring local food security. However, performance of existing projects in line with their objectives is seldom known. This study aimed at assessing the technical and economic performance of Matanya, Thome and Aguthi smallholder irrigation schemes. The first component assessed yield response of maize (hybrid 511) to different levels of irrigation water using 33%, 66% and 100% of the computed irrigation water requirement (IR).

The African Green Revolution and the Role of Partnerships in East Africa

Sub-Saharan African (SSA) region continues to experience perennial hunger, poverty and poor health of its people. Agricultural production has remained low over decades and is declining to extremely low staple maize yields below 0.5 t ha–1 season–1 at the smallholder farm scale, against the potential of 4–5 t ha–1 season–1 given modest levels of inputs and good crop husbandry. Constraints contributing to low productivity are numerous, but the planting of poor-quality seed, declining soil fertility, poor markets and value addition to products significantly contribute to poor productivity.

Performance of Three-Way Cross Hybrids for Agronomic Traits and Resistance to Maize Streak Virus Disease in Kenya

Maize Streak virus (MSV) disease is a major disease in many parts of Africa, and is the most important viral pathogen of maize in Kenya. A study was conducted in 2004 to evaluate the agronomic performance and maize streak virus (MSV) resistance of maize ( Zea mays check for this species in other resources L.) three-way crosses developed in Kenya. Twenty hybrids and one check were grown under normal conditions in a randomized complete block design, in two replications at Embu, 1540 masl; and Muguga, 2093 masl).
