Crop management research and extension: The products and their impact on productivity
This study presents a methodology (in five steps) for assessing the impact of information and technologies generated by a crop management research (CMR) program. The methodology is demonstrated by estimating the return to ...
Increasing wheat yields sustainability through agronomic means
This paper examines common factors that constrain wheat yields: insufficient nutrients (using nitrogen as an example); problems of late planting and poor crop establishment; suboptimal water management; lodging; and weeds. ...
The normalized difference vegetation index (NDVI) Greenseeker(TM) handheld sensor: toward the integrated evaluation of crop management part A: concepts and case studies
Reflectance is the ratio of energy that is reflected from an object to the energy incident on the object. Spectral reflectance of a crop differs considerably in the near infrared region (λ = 700-1300 nm) and in the visible ...
Effect of stubble management, tillage and cropping sequence on the severity of take-all and eyespot diseases of wheat
(African Crop Science Society, 2002)
Bread wheat (Triticum aestivum L. em Thell) is affected by several soil- and stubble-borne diseases in Ethiopia, including take-all and eyespot, which often necessitate instituting control. In this study, the efect of ...
