Growth and Yield Response by the Seeds Harvested at Different Stages of Siliquae Maturity of Rapeseed-Mustard Varieties
Journal Title: Scholars Bulletin - Year 2018, Vol 4, Issue 7
Abstract
Abstract:An experiment was conducted at the Regional Agricultural Research Station, Jamalpur, Bangladesh which geographic coordinates located between 24034ʹ and 25026ʹ north latitude and between 89040ʹ and 90012ʹ east longitude during the period from November, 2015 to March, 2016 to observe the growth and yield performances of the rapeseed-mustard varieties under field condition grown from the seeds of different stages of siliquae maturity of the previous year experiment. Four rapeseed-mustard varieties viz. BARI Sarisha-11 (V1), BARI Sarisha-14 (V2), BARI Sarisha-6 (V3) and Tori-7 (V4) and seeds of those varieties harvested at four stages of siliquae maturity viz. H1 = Green stage of siliquae, H2 = Pale yellow stage of siliquae, H3 = Golden yellow stage of siliquae and H4 = Full maturity stage of siliquae were included as the treatments in the experiment. Harvested seeds of the previous year were stored in air tight polythene under freezing condition till set up the experiment. Results revealed that four rapeseed-mustard varieties varied significantly for most of the parameters studied. Variety V1 produced significantly the highest seed yield (1.99 t ha-1) while the lowest (1.04 t ha-1) was recorded from V4. Seeds of H2, H3 and H4 stages produced statistically similar and significantly higher seed yield ranges from 1.57-1.65 t ha-1 (H4>H3>H2)) than that of H1 stage which produced the lowest (1.34 t ha-1) mainly due to the poor stand establishment. Interaction effects of varieties and seeds harvested at different stages of siliquae maturity did not show significant variation in expressions of seed yield and yield contributing parameters. Keywords:Siliquae maturity, Plant establishment, Growth, Yield, Rapeseed-mustard.
