The strains of the pathogen used had been isolated from wheat collected in different growing areas of Kenya. Head blight susceptibility was assessed as the percentage of spikelets bleached and area under disease progress curve; kernel colonization by fungal mycelium was determined as ergosterol content...
The results therefore indicatedthat head blight is widely distributed at low levels in the wheat growing areas investigated. This inoculum is potentiallycapable of producing severe infections under optimum weather conditions. 展开 被引量: 23 年份: 2003 ...
The Njoro station is in the middle of Kenya’s wheat growing area near Nakuru. La estación Njoro se localiza en la parte central de la zona productora de trigo de Kenia, cerca de Nakuru. ParaCrawl Corpus The Durum wheat growing areas are subjects to various biotic and a-biotic stresse...
Because winters are generally mild, RWA remains in an anholocyclic reproductive state and no sexually active males appear. This anholocyclic state results in large widespread infestations by winged females that colonize extensive areas under barley or wheat cultivation (Walters, 1984; Jankielsohn, ...
This sampling methodology permitted a large, representative sample of the main wheat growing areas in Ethiopia to be obtained. It was particularly cost-effective as sampling and surveys were undertaken as part of the existing annual AgSS national survey. All grain samples and filled-in survey questi...
Rice production and food security in Asian Mega deltas—A review on characteristics, vulnerabilities and agricultural adaptation options to cope with clima... Asian Mega deltas (AMDs) are among the worlds most important rice‐growing areas and vital for food security. This review describes the maj...
The low adoption is however blamed on the introduction of the crop that positioned it as a large scale crop and non African, hence keeping small scale farmers from growing it. Its production had been restricted in South Africa, North Africa and the Highlands of Ethiopia and Kenya. ...
genes (Ppd1andPpd2) along with the dwarfing genes (Rht1andRht2) have enabled to the development of high yielding, widely adapted, lodging resistant and input responsive spring bread wheat varieties[69,70]. The CIMMYT wheat breeding program has established the Njoro station in kenya as additiona...
6B). Additionally, the joint impact of AI and TS was evaluated and it was found that high yields were generated in areas with TS of 2 and AI between 100 to 200, and similar results were seen in areas with TS of 3 and AI of 400 (Fig. 6C). Figure 6 Relationship between growing ...
This type of new ‘no-tillage’ technology was introduced to farmers in the cotton–wheat areas by the extension system in the late 1980s (Nayyar and Chatha, 1992; Cheema, 1992; Chatha and Nahang, 1995). Despite the undoubted economic returns associated with their use, the adoption rate ...
