Abstract:
A field experiment was conducted at the Agronomy research field of Sher-e-Bangla
Agricultural University, Dhaka, during the period from November 2014 to June 2015 to
observe the effect of sowing dates and variety on growth, yield and quality of chickpea.
The experiment comprised of main plot: two chickpea varieties: BARI Chola-5 and BARI
Chola-9 and sub-plots to be five different sowing dates: November 05, November 20,
December 05, December 20 and January 04. The experiment was laid out in split- plot
design with three replications. The results revealed significant variations in date to
emergence, plant height, number of branches plant
maturity, number of pods plant
-1
, pod length, seeds pod
-1
, days to first flowering, days to
-1
, weight of 1000 seeds, seed
yield, stover yield, biological yield, shelling percentage and harvest index due variety and
sowing dates. Seed quality attributes viz germination percentage, vigor index, number of
leaves per seedling, shoot length, root length and total dry matter content of seedling also
varied due to variety and sowing time. Delayed sowing affected the chickpea plant
growth, its yield and the quality of seed. In the case of varieties, more or less significant
variation was observed in all parameters, here, BARI Chola-9 showed better performance
over BARI Chola-5. Interaction of variety and sowing date significantly affected the seed
yield. BARI Chola-9 sown on November 20 produced maximum seed yield
and that the lowest seed yield
January 04. The maximum weight of 1000 seeds, highest stover yield, harvest index,
maximum germination percentage and vigor index were found when chickpea was sown on 20 November and ensure the best performance. Irrespective of variety, delayed
sowings showed lower performance on all parameters especially yield contributing
parameters and yield of chickpea
