Abstract:
An experiment was conducted at Barga village under Kalihati upazilla of Tangail
district during the period from August to December. 2011 to study the effect of
urea top-dress and ball placement on the growth, yield and nutrient content of retransplanted
Aman rice (BINA sail) using completely randomized design with
three replications. During the experiment, two urea application methods (U1 =
Urea top-dress and 1)2 = Urea ball placement) and 4 transplanting and retransplanting
dates (1, = 16 September. 'l'2 = 23 September, T3 = 30 September
and f4 = 07 October) were used. The highest number of total tillers hilt', effective
tillers hilt', non-effective tillers hill". spikelet panicle". filled grains panicle".
unfilled grains panicle4. 1000-grain weight and the longest panicle was found in
U2 while plant height was highest in U1. The highest N content in straw (0.40 %)
and grain (1.02 %) were observed in U2 but P & K content (in both straw and
grain) were highest in U1. In case of planting dates, T2 showed highest results for
most of the growth and yield parameters while T4 produced the lowest. But noneffective
tillers hill" and untilled grains panicle" were highest in T4 and lowest in
T2 and T,. For N. P and K contents in straw and grain, the highest results were
recorded in T, followed by T2 while 'F4 produced the lowest. Due to the interaction
effects of two factors, U2T2 showed better results followed by U ,T2 and Ii ,T, and
poorest performances were given by U,T4 and U2T4.
