Abstract:
An experiment was conducted at the Agronomy laboratory with storing wheat
seed and subsequent study in Agronomy field ofSher-e-Bangla Agricultural
University, Dhaka during May 2011 to March 2012 to find out the influence of
different storage conditionson wheat seed and to evaluate on different seed
source of the growth and yield performance of stored seeds. The experiment
was carried out in randomized complete block design with two factors
comprising three seed source viz.,i) S

= BARI seed, ii) S
= BADCseed and

condition of seed and their combinations had significant effect on yield and
harvest indexof wheat.BARI seed showed the highest grain yield (3.48 t ha
