Abstract

Investigation was carried out at the Horticulture Farm of Bangladesh Agricultural University, Mymensingh during 1992-93 and 1993-94 growing seasons to study the effects of storage conditions of seed tubers on the subsequent crop performance of some indigenous potato varieties. Seed tubers (20-30 mm dia) were stored either in cold storage (6-8°C and 85-90% relative humidity) or in diffuse light storage under thatched house conditions. Plant emergence, percent foliage coverage at 60 DAP and the number of tubers per hill were significantly higher in plants from cold-stored seed tubers. There were no significant effects of storage conditions of seed tubers on plant height and yield of tubers in 1992-93. Seed tubers stored in cold storage produced higher yield in 1993-94. Yield of the indigenous potato varieties differed widely. Also significant interactions were observed among varieties and storage conditions of seed tubers. The results of the two separate experiments in two subsequent years indicate that diffuse light storage of seed tubers in farm-house conditions may be practiced without substantial yield loss of indigenous potatoes in Bangladesh.
