| dc.description.abstract | Abstract :
The experiment was conducted at the research field of the Department of Horticulture, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during the potato growing season of 2013-14 with four potato varieties viz., Asterix, Cardinal,
Diamant, and Granola. The purpose of this study was to evaluate the pattern of dry
matter accumulation pattern in different organs at different days after planting (DAP).
Results revealed that dry matter accumulation in the plant parts (leaf, stem, root, and tuber) showed an increasing trend from 30 to 80 DAP irrespective of varieties. All the varieties produced maximum stem and leaf dry weights at 80 DAP but insignificantly.
Asterix and Cardinal attained maximum root diy mass at 80 DAP. But in case of Diamant and Granola, it was maximum at 70 DAP and decreased at 80 DAP. Rate of dry matter accumulation to tubers from 30 DAP to 60 DAP increased linearly and after that increased steadily. At 30 DAP, maximum dry matter was found to be accumulated to leaves followed by that of stem, root, and tuber. This trend was changed from 50 DAP till harvest, and maximum dry matter was accumulated to the tubers followed by that of leaf, stem, and root. | en_US |
