Agricultural activities form the backborne of Kenya´s economy. Inorder to control crop losses, pesticides are used and in the recent past, more of the pesticides have been used to increase production. However, the effect ...

The Thika River catchment has undergone tremendous changes in land use and land cover in the recent past. These changes are suspected to have impacted negatively on the hydrology and soil conservation of the catchment. In ...

Soil nitrogen deficiency is a major factor limiting soybean production. This problem can be alleviated by the use of nitrogen fertilizers which on the other hand adversely affect the environment, are expensive and ...

Chambers and Dorfman (2002) constructed bootstrap confidence intervals in model based estimation for finite population totals assuming that auxiliary values are available throughout a target population and that the auxiliary ...

We propose a nonparametric regression approach to the estimation of a finite population total in model based frameworks in the case of stratified sampling. Similar work has been done, by Nadaraya and Watson (1964), Hansen ...

Kenyan farmers are threatened by overreliance on few crops whose yields are reduced by adverse climatic changes. Bananas are more resilient and produce year round, making it a more suitable crop. To increase banana production, ...

Biological nitrogen fixation (BNF) by promiscuous soybean cultivars offers a potential for minimizing the investment made by resource-limited farmers in central highlands of Kenya. Nitrogen fixation in this grain legume ...

With the unrelenting increase in human population it is important that concerted efforts be made to increase crop productivity so as to match the expected increase in food demand. The gravity of this problem is well ...

Tissue culturing has become a routine method for propagating plants in high technology laboratories. The cost of production using conventional tissue culture is, however, high for most of the countries in the sub-Saharan ...

As children grow, they transition from home to school environments, where they acquire and master knowledge and skills, and develop an image of themselves as learners and develop several types of relationships with adults ...
