Effects of pyridoxine and different levels of nitrogen on qualitative and quantitative yield of Physalis alkekeng.

Alkekengi (Physalis alkekengi) is a medicinal plant from Solanaceae family which contains some important alkaloid compounds including Physalin. To evaluate the effect of pyridoxine and different levels of nitrogen fertilizer on yield of the alkekengi medicinal plant used the randomized complete block design with three nitrogen levels (included total application of 100 (control), 150 and 200 kg N ha-1) in the main plots and three pyridoxine treatment included 0 (control), 0.02% and 0.04% in subplots in three replications. Results of this study shows that both pyridoxine and nitrogen treatments have significant positive effects on yield of alkekengi. According to the results, 0.04% pyridoxine and 150 kg N ha-1 treatment resulted in maximum values for yield, as compared to other treatments. The lowest yield was obtained by application of 100 kg N ha-1 and no pyridoxine (control treatment). * Corresponding Author: Atefeh Khoshlahjeh  a.khoshlahjeh@yahoo.com
