Effects of Specialized Curing on the Income and Behavior of Tobacco Growers AgEcon
Huang, Kejiu; Zhang, Wenping; Ma, Xiao; Yang, Chao; Ji, Xinwei; Song, Zhaopeng.
Qingshuitang Village near the Qingmuchi Village is taken as the control region, which has similar status of social economy and flue-cured tobacco cultivation and has not implemented specialized curing. Permanent residents above the age of 18 in the two villages are investigated. Due to the dispersibility and randomness of samples, questionnaires are sent out randomly considering the differences in age, sex, education level, economic income and planting area. Excel is used to conduct statistics and analysis of survey data. Result shows that specialized curing has significant higher incentive effect on economic income of tobacco growers than the non-specialized curing. Tobacco growers in specialized curing area have apparently different attentive focus of...

COMMODITY POLICY, PRICE INCENTIVES, AND THE GROWTH IN PER-ACRE YIELDS AgEcon
Foster, William E.; Babcock, Bruce A..
We estimate the influence of policy-induced price changes and of technology supply on North Carolina flue-cured tobacco yields. The decline in land rent and effective output price that accompanied a 1965 policy change from acreage allotments to poundage quotas caused a 12 percent decrease in yields. Farmer yields were more responsive to yield-increasing technologies under acreage allotments than under poundage quotas. Annual yield growth was 0.5 percent under poundage quotas and 4.32 percent under acreage allotments. The growth rate decline is attributable to changes in relative prices and to a slowdown in the supply of available technologies.

Genetic Diversity among Flue-cured Tobacco Cultivars Based on RAPD and AFLP Markers BABT
Zhang,Han Yao; Liu,Xiao Zhen; He,Chuan Sheng; Yang,Yu Ming.
The aim of this work was to study the genetic diversity among flue-cured tobacco cultivars. RAPD and AFLP analyses were used to assess the genetic similarity among selected accessions of flue-cured tobacco. Seventy eight RAPD and 154 AFLP polymorphic bands were obtained and used to assess the genetic diversity among 28 tobacco accessions. The cultivar relationships were estimated through the cluster analysis (UPGMA) based on RAPD data and AFLP data. The accessions were grouped into three major clusters and these shared common ancestry clustered together.
