Two years field experiment was conducted during rabi seasons of 2015-16 and 2016-17 at Instructional
Farm (Agronomy), Rajasthan College of Agriculture, MPUAT, Udaipur. The experiment comprised of
fifteen treatments viz. pendimethalin 0.75 kg ha-1
; sulfosulfuron 0.025 kg ha-1
; metribuzin 0.21 kg ha-1
;
clodinafop 0.06 kg ha-1
; metsulfuron 0.004 kg ha-1
; pendimethalin + metribuzin 0.75+0.175 kg ha-1
;
pendimethalin fb sulfosulfuron 0.75+0.02 kg ha-1
; pendimethalin fb clodinafop 0.75+0.05 kg ha-1
;
pendimethalin fb metsulfuron 0.75+0.004 kg ha-1
; metsulfuron + sulfosulfuron 0.003+0.02 kg ha-1
;
pinoxaden + metsulfuron 0.06+0.004 kg ha-1
; mesosulfuron + iodosulfuron 0.012+0.0024 kg ha-1
;
clodinafop + metsulfuron 0.06+0.004 g ha-1
, two hand weeding at 30 & 45 DAS and unweeded control,
replicated four times in Randomized Block Design. Wheat variety Raj.- 3765 was used as a test crop.
Application of metsulfuron + sulfosulfuron significantly increased the plant height and dry matter
accumulation at different growth stages over unweeded control resulted into higher yield attributes viz.
effective tillers m-1
row length (93.97), grain ear-1 (44.82) and 1000 grain weight (44.14g). Consequently,
highest grain (4412 kg ha-1
), straw (6201 kg ha-1
) and biological yield (10898 kg ha-1
) were obtained
through controlling weeds by metsulfuron + sulfosulfuron after two hand weeding which was at par with
mesosulfuron + iodosulfuron (4378, 6173 and 10861 kg ha-1
) followed by clodinofop + metsulfuron and
pinoxaden + metsulfuron and proved significantly superior over rest of the treatments. As a consequence,
significantly higher net return (` 63827 ha-1
) and B-C ratio (2.34) were also acquired by metsulfuron +
sulfosulfuron followed by mesosulfuron + iodosulfuron (` 63226 ha-1 and 2.32).
