Popularization of high yielding varieties of wheat (Triticum aestivum L.) in West Bengal state through Frontline Demonstrations Popularization of high yielding varieties of wheat (Triticum aestivum L.) in West Bengal state through Frontline Demonstrations

Abstract

Field trials were conducted in far􀅵ers’
fields of Nadia, Murshidabad and Bardhaman
district of West Bengal state under frontline
demonstration to study the potential of high
yield cultivar. Total 32 Frontline
demonstrations (FLDs) at farmers field were
laid out on wheat (Triticum aestivum L.) to
demonstrate production potential and
economic benefits of improved practices (IP)
comprising high yielding varieties namely DBW
107 and HD 2967 during rabi seasons from
2014 - 16 in irrigated farming situation.
Improved technology intervention revealed
that, grain yield of DBW 107 (24.21 q/ha) and
HD 2967 (31.35 q/ha) was quit high compared
to farmer cultivar with UP 262 (21.06 q/ha) and
Sonalika (22.98 q/ha). These varieties enhance
14.94 and 36.42 percent more grain yield over
UP 262 and Sonalika. Straw yield was almost
similar between DBW 107 (44.23 q/ha) and UP
262 (43.33 q/ha). However this was quite
prominent in case of HD 2967 (59.65 q/ha)
compared to tested farmer cultivar Sonalika
(49.69 q/ha). Higher B:C ratio observed with
HD 2967 (1.57) and was followed by DBW 107
(1.32). The productivity of wheat per unit area
could be increased by adopting feasible
scientific and sustainable management
practices with a suitable variety.
