EFFECT OF STORAGE CONDITONS AND DURATIONS OF UPROOTED SEEDLINGS ON THE PERFORMANCE OF AROMATIC RICE

Abstract

An experiment was conducted at the Agronomy Field Laboratory, Sher-e-Bangla Agricultural University, Dhaka during the period from July, 2006 to December, 2006 with the objective to find out the effect of storage conditions and durations of uprooted seedlings on the performance of aromatic rice. The experiment was carried out in a Randomized Complete Block Design with three replications. Two storage conditions such as i) on the mud and ii) in the water with six storage durations viz. 0, 2, 4, 6, 8 and 10 days were included in the experiment. Results revealed that the storage conditions had significant effect on plant height, number of tillers hill nmber of effective tillers hill panicle -1 -1 , number of filled panicle -1 , number of non-effective tillers hill -1 , total dry matter production, , number of unfilled grains panicle -1 , number of total grain -1 , grain yield, straw yield and biological yield The best performance was exhibited by the seedlings which were stored on the mud. Storage durations also showed significant effect on plant height, number of tillers hill effective tillers hill -1 -1 , total dry matter production, number of total hills m , number of non-effective tillers hill number of filled grain panicle -1 -1 2 , number of , number of total grain panicle , grain yield, straw yield and biological yield. The uprooted seedlings were found to be storable in mud up to 4 days and in water up to 2 days without any appreciable loss in grain yield.
