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 ...
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 ...
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 ...
