Biocontrol approach to management of greenpeach aphid Myzus persicae in garden peas for a sustainable ecosystem
Green peach aphid has been a significant pest of garden peas in Kenya for many years, because of its capacity to transmit viruses. Despite advances in integrated pest management, and frequent use of insecticides, the industry is still plagued by the insect. Adding to the problem is the fact that the peach aphid has proved to be resistant to various insecticides; there is a need to shift emphasis on biological control...

This compels most farmers to use planting materials from informal sources such as previous harvests, local markets and neighbours. Kenya Agricultural Research Institute (KARI), Tigoni has the national mandate to produce basic seed tubers but can only supply much less than 1% of the national seed requirements. In order to improve...

Growth habit, plant density and weed control on weed and root yield of sweet potato (Ipomoea batatas L.) Areka, Southern Ethiopia
Sweet potato is mostly left unweeded or weeded lately. Effect of variety, plant density and weeding frequency on weed and tuber yield was studied from 1992 to 1994. Three varieties (Tis 1499: erect and early; Tis 2498: long vine, spreading and early, and Koka 6 intermediate), two weeding frequencies (30 to 40 (W1) and 70 days after sprout (DAS) (W2), and four plant densities (5, 7, 10, and 12.5 plants m-2) were laid out...

Effect of photoperiod on propagation of Strawberry (Fragaria × ananassa Duch.)
The effect of photoperiod on multiplication of commercial strawberry cultivars was investigated at the Malaysian Agricultural Research and Development Institute (MARDI) Station in Cameron Highlands. Two strawberry cultivars, Camarosa and Camaroga, were grown under a plastic rain-shelter supplemented with three levels of photoperiod, 12 (normal day length of Cameron Highland), 15 and 17 h. The result showed that...
