Leaf area estimation of Burley tobacco

Rapid estimation of sunflower leaf area from linear measurements

Leaf area estimation by a simple and non-destructive method

In this study, the relation between leaf area and its dimensions was estimated using a non-destructive method. This method is based on this fact that the leaf shape does not change during the growing season. In this method, leaf area during the growing season is estimated based on the dimensions of the smallest leaf in the initial stage of plant growth or at any growth stage by measuring the le...

Antioxidant activities of polysaccharide fractions isolated from burley tobacco flowers

The crude polysaccharide extracted from the flowers of burley tobacco hybrid Eyan 1 was fractionated on a Sepharose CL-6B chromatography to get two purified polysaccharide fractions (termed Fr-I and Fr-II). The monocarbohydrate compositions revealed both fractions were heteropolysaccharide. Fr-I was mainly composed of mannose, galactose, ribose and arabinose, while Fr-II was composed of mannose...

The Import Demand for U.s. Burley Tobacco in European Markets

One of the chief complaints against the federal importer of burley tobacco. Italy, Greece, South tobacco program is that it sets prices too high Korea, and almost every other burley exporting relative to foreign tobaccos: most foreign burley country import substantial amounts of burley. tobaccos are priced between one-third and oneThese foreign exporters typically import large half the price of...

Burley Tobacco Clubs in Malawi: Nonmarket Institutions for Exports

This paper studies nonmarket institutions that facilitate exports. In Malawi, as in many other developing countries, farmers face numerous constraints that disconnect them from export markets. We explore the role of a local institution, the burley tobacco clubs, in bridging smallholders to exports. Burley clubs potentially enable farmers to increase their tobacco farming productivity by providi...
