Growth and Yield of Different Size-Seedling Tubers Derived from True Potato (<i>Solanum tuberosum</i> L.) Seeds as Influenced by Clump Planting

Abstract

An experiment was conducted at the Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during November 2010 to March 2011. Four levels of seedling tuber size, viz. 6-<7 g (S₁), 7-<8 g (S₂), 8-<9 g (S₃) and, 9-?10 g (S₄) and three levels of seedling tuber, viz. 1 hill^-1 (N₁), 2 hill^-1 (N₂) and 3 hill^-1 (N₃) were laid out in a Randomized Complete Block Design with three replications. At harvest, the tallest plant (82.17 cm), highest number of leaves plant^-1 (83.30), highest LAI (6.23), tubers weight hill^-1 (128.90 g) and tuber yield ha^-1 (25.78 t) were found in S₄, while the lowest was in S₁. On the other hand, the tallest plant (74.91 cm), highest number of leaves plant^-1 (74.45), highest LAI (5.41), tubers weight hill^-1 (123.95 g) and tuber yield ha^-1 (24.79 t) were found in N₃, while the lowest was in N₁. The tallest plant (85.09 cm), highest number of leaves plant^-1 (87.97), highest LAI (6.64), tubers weight hill^-1 (138.35 g) and tuber yield ha^-1 (27.67 t) were found in S₄N₃ and the lowest gross tuber yield ha^-1(12.83 t) was from S₁N₁. Large seedling tuber with single seedling tuber hill^-1 performed better.
