Effect of transplanting and direct seeding on seed yield & important agronomic traits in rapeseed (Brassica napus L.)

Abstract

In order to compare the effect of transplanting and direct seeding methods on rapeseed (Brassica napus L.) in terms of
agronomic traits, seed yield and yield components an experiment was conducted in a factorial arrangement in randomized
complete block design with three replications during 2017-18. Investigating factors included rapeseed genotypes Zafar,
L22, L17, and Hyola420 and culture methods were transplanting and direct seeding methods. The analysis of variance
revealed significant effect of cultivars on all studied characteristics viz., number of pods on main raceme, number of pods
per plant, pod length, number of seeds per pod, 1000- seed weight, seed yield and oil content. The average seed yield of
genotypes in transplanting and direct cultivation methods was 3114 and 2312 kg ha-1, respectively which were classified
in two distinct statistical classes. All the traits progressively increased in transplanting cultivation method. Correlation
between seed yield and yield components were positive and significant indicating a positive and significant effect of
these traits on seed yield in both cultivation methods.
