Breeding beans for smallholder farmers in Eastern, Central, and Southern Africa: Constraints, achievements, and potential

Serious declines in food security and income in sub-Saharan Africa over the past two decades have resulted
in widespread poverty and malnutrition, especially among resource-poor smallholders and the urban poor.
The common bean is a major part of their food requirements and source of income, but there have been
declines in bean productivity, attributable to a number of factors and estimated at nearly 3,000,000 t per
year. In the last 16 years, the Pan-African Bean Research Alliance (PABRA) together with NARS partners,

The impact of changes in foreign exchange rates on volume of horticultural exports in Kenya

The objective of this study was to establish whether there is a relationship between changes in foreign exchange rates and volume of horticultural exports in Kenya. To achieve this objective, monthly export values for all firms continuously involved in the production and export of horticultural crops as provided by HCDA were analysed together with the monthly exchange rates (USD to KES) obtained from Central Bureau of Statistics for the period 1st January 2001 to 31st December 2006.

Environmental influence on competitiveness of the horticultural processing industries in Kenya

Horticultural Processing Industry has progressively grown over time with increasing number of players. This has increased the competition among the players hence the need to become more competitive. Due to this, the Horticultural Processing Industries are adopting different competitive strategies to counter the influence of economic, technological and ecological environmental factors. This study sought to establish the environmental influence on competitiveness of the horticultural processing industries in Kenya.

Effect of nitrogen and cane density on cane architecture, fruit and fruit yield components in primocane bearing red Raspberries

Nitrogen fertilization and cane density management are the most critical factors in the commercial production of red raspberries. In general, little is known about these factors in relation to primocane bearing red raspberries and their effect on fruit yield. In two separate experiments, four levels of nitrogen and four levels of cane density were investigated on 2 primocane bearing red raspberries, Rubus strigosus, selections '8008' and '8114', respectively. The experiments were conducted at three sites in Manitoba: a clay soil at st.

Farm demographics and pig management practices of Smallholder pig farms in Kikuyu division, Kiambu district

A cross-sectional study was conducted in a high-potential peri-urban area in Kenya to obtain baseline information on Farm Demographics and Pig management practices of Smallholder pig farms. Using a simple random selection, 87 smallholder pig farms were selected from a total of 179 farms. Data on important farm management factors including, feeding, housing, breeding, preventive measures and general husbandry practices were gathered using semi structured questionnaires.

Flowering and fruiting of purple passion fruit at Thika.

Vines started to flower 5 months after transplanting. The flowers opened between 7 and 9 a.m., depending on the weather conditions, and they remained open until 10 a.m. the following day. Fruit set of flowers covered with paper bags was 60%, and this increased to 83% for uncovered flowers. Fruits attained their maximum size and full maturity 24 and 88 days, respectively, after anthesis. Fruiting was seasonal and production declined markedly over a 3-year period.

Molecular basis of cell wall degradation during fruit ripening and senescence

Purpose of review: This review highlights progress made in the recent past in understanding the molecular basis of cell wall changes during fruit ripening and senescence. Recent findings: Gene expression studies in several fruit have continued to show that isoforms of various classes of cell wall modifying enzymes and proteins are involved in cell wall disassembly during fruit ripening and senescence.

ffect of drip irrigation on the production and economic returns of sorghum (sorghum bicolor) in semi arid areas of Tanzania

Field trials were conducted in semi arid area of Dodoma, central Tanzania with the aim of
assessing the effect of three drip irrigation watering regimes on the production and economic
returns of sorghum (Sorghum bicolor). The irrigation treatments were: EM (early in the
morning), EL (late in the evening) and ELE (both early in the morning and late in the evening).
Each treatment was replicated three times in a RCBD for two seasons (dry and wet season).
The results showed that both sorghum growth parameters and yield were significantly higher by

Pruning and trellising purple passion fruit. II. Disease incidence, fruit size and quality.

Trellising did not affect fruit size or quality. Three-wire trellising produced more diseased [Alternaria passiflorae] laterals and fruit than 1-wire trellising. Light and selective pruning produced heavier and better quality fruit than severe or no pruning.ADDITIONAL ABSTRACT:In comparative experiments 3-wire trellising produced more diseased laterals and fruit than 1-wire trellising.

Cyanogenesis in passion fruit. I. Detection and quantification of cyanide in passion fruit (Passiflora edulis Sims) at different stages of fruit development.

Data are presented on the cyanide content of passion fruits at 5 stages of ripeness from young to ripe (fallen and wrinkled). The cyanide content declined progressively during ripening and that of fresh ripe fruits was far below the toxicological limit for human consumption.
