ABSTRACT

The experiment was conducted at Agronomy research field of Sher-e-Bangla Agricultural University, Dhaka, during 10 November 2012 to 10 March 2013 to observe the response of seedling tuber weight and plant spacing on yield and economic analysis of potato. Four weight of seedling tubers viz., 40 ± 2, 30 ± 2, 20 ± 2 and 10 ± 2 g and three plant spacing viz., 60 cm × 25 cm, 60 cm × 20 cm and 60 cm × 15 cm were used as treatment and laid out in Randomized Complete Block Design (RCBD) with three replications. Results revealed that in general yield attributes such as tubers hill-1 and tuber weight and tuber yield of gross, marketable and non-marketable were significantly influenced by seedling tuber weight and plant spacing .The highest tuber yield ha-1 both gross and marketable was recorded in the tuber weight of 30 ± 2 g due to increased number of tubers hill-1 and tuber yield hill-1 and the lowest from smaller seedling tuber of 10 ± 2 g. Results showed that tubers hill-1, single tuber weight and tuber weight hill-1 increased with increasing plant spacing. The highest gross and marketable tuber yield ha-1 was observed in the plant spacing of 60 cm × 20 cm and the lowest from closer spacing of 60 cm × 15 cm. For combined effect of seedling tuber weight and plant spacing, the highest gross and marketable tuber yield was observed in the treatment combination of 40 ± 2 g seed tuber with the plant spacing of 60 cm × 25 cm. But economic point of view with high yield performance, the seedling tuber size of 30 ± 2 g with plant spacing of 60 cm × 20 cm was more profitable than those of other treatment combinations.
