Abstract
The different levels of arsenic (As) had significant effect on growth contributing parameters of potato varieties. All parameters studied in this experiment were decreased with the increasing As levels. The results showed that though most of the growth parameters decreased with the increasing As levels but remained statistically similar up to 25 mg As kg-1 soil and thereafter drastically decreased. Among the potato varieties, Felsina gave the maximum number of stems hill-1, stem diameter, leaf area plant-1 and also chlorophyll content (SPAD value) of leaves, irrespective of As levels. Among the treatment combinations, ‘Felsina’ cultivated with 0 mg As kg-1 soil performed the best results and the same variety with 25 mg As kg-1 soil also showed the statistical similar results in terms of growth parameters.
