Effect· of barrier crop on yield, out-crossing and pollinator activity in pigeonpea [Cajanus cajan (L) Millsp.]

Published on

The efficiency of different width of Sesbania aculeata pers.
(Dhaiancha) barrier crop on yield, natural outcrossing and
pollinator activity was studied at I.A.R.I, Delhi centre using
growth habit (determinate vs indeterminate 't) as the
genetic marker. Significant decrease in yield and its
components was recorded on MS Prabhat DT with an
increase in the width of barrier crop from 6-rows to
12-rows. The data indicated natural outcrossing rates in
the range of 0.0 to 17.5 (mean 7.8%) and 0.0 to 21.3
(mean 10.1%) per cent in kharif and rabi seasons,
respectively. Barrier crop was proved to be effective in
reducing the amount of out-crossing by 54.1 % and
pollinator activity by 53.7% at the maximum width of 18
rows barrier.
