The effect of fosetyl-Al application on stomata in tomato (Lycopersicon esculentum Mill.) plant

May 2009

  In this study, a fungicide namely Aliette WG 800 (80% Fosetyl-Al) was pulverized on tomato (Lycopersicon esculentum Mill.) grown under greenhouse conditions and the likely effects of this fungicide on stomata of tomato were examined. Applications of Fosetyl-Al were carried out at recommended dosage (200 g/100 L water) as given on the label and two fold higher (400 g/100 L water) dosages. The fungicide...

Status of macadamia production in Kenya and the potential of biotechnology in enhancing its genetic improvement

May 2009

  Macadamia (Macadamia spp.) is considered the world’s finest dessert nut because of its delicate taste and numerous health benefits. It is grown in Kenya both as a cash crop and foreign exchange earner with Kenya producing about 10% of the world’s total production. Macadamia has great potential for poverty reduction due to the high value of its products and its low requirement for external...

Grain filling rate is limited by insufficient sugar supply in the large-grain wheat cultivar

May 2009

  Wheat grain yield can be limited by source, sink or by both. Inconsistency of the previous results reflects the interactions between genotypes and environments. In north China where the hot, dry wind was frequent during grain filling, new winter wheat cultivars with large grains suffer from loss of grain weight quite often because the grain filling rate (GFR) is low. In the present study, the carbohydrate...

Indigenous pest and disease management practices in traditional farming systems in north east India. A review

May 2009

  Traditional farming system is an ecologically based age-old farming system developed by ancient farmers through generations of their interaction with nature and natural resources for food, fodder and fiber. Indigenous knowledge is the knowledge of the indigenous people inhabiting different geographical regions of the world with their own language, culture, tradition, belief, folklore, rites and rituals. This...

Intercropping and its application to banana production in East Africa: A review

April 2009

  Bananas are very important in Kenya for domestic consumption and export. They are extensively grown where they are mainly intercropped with short term crops. There has been an increase in the grower interest in using intercropping-growing two or more crops simultaneously on the same land  in the development of new cropping systems for their land. Intercropping could reduce management inputs and result in...

Genetic yield stability in some sunflower (Helianthus annuus L) hybrids under different environmental conditions of Sudan

April 2009

  Nineteen locally developed sunflower (Helianthus annuus L.) hybrids and an introduced one (Hysun 33) were evaluated at two irrigated locations, New Halfa and Rahad for two consecutive seasons (2003/04 and 2004/05) in order to estimate stability of performance for seed yield per ha (t). A randomized complete block design with four replicates was applied at each location. Data on seed yield was collected....

Resistance in Kenyan bread wheat to recent eastern African isolate of stem rust, Puccinia graminis f. sp. tritici, Ug99

April 2009

Stem or black rust, caused by Puccinia graminis, has historically caused severe losses to wheat (Triticum aestivum) production worldwide. The causal race, commonly known as Ug99 and designated as TTKS based on the North American nomenclature, carries virulence for several genes commonly present in wheat germplasm. All Kenyan germplasm are known to be susceptible or partially susceptible to Ug99 although no proper...

Influence of temperature and genotype on Pythium damping-off in safflower

March 2009

  Improvement of genetic potential in safflower (Carthamus tinctorius) against Pythium species would be an efficient means of control of this major seed and seedling fungal pathogen. The type and content of reaction for plant to pathogen could be severely affected by environmental conditions such as temperature. In this study seed rot and seedling damping-off of fourteen safflower genotypes that came from...

Genetic polymorphism in exotic safflower (Carthamus tinctorious L.) using RAPD markers

March 2009

  Safflower is a drought tolerant annual oil crop and this gives it an advantage over the other crops in the drier parts of Kenya. It is valued worldwide as a source of high quality vegetable oil. In the past, characterization of safflower using molecular markers has been limited. The objective of this study was to evaluate the degree of polymorphism in 36 safflower accessions using RAPDs. Sixty-one...
