The straw yield (kg ha -1 ) of French bean was differed significantly due to different weed
control treatments. The weed free treatment (T 6 ) recorded significantly higher straw yield
(2612 kg ha -1 ) which was at par with treatment Quizalofop-p-ethyl 5% EC 100 g a.i. ha -1 at
20 DAS (POE) (T2), Pendimethalin 30% EC @ 1.0 kg a.i. ha -1 (PE) + One hoeing at 30 DAS
(T 3) and Quizalofop-p-ethyl 5% EC 100 g a.i. ha -1 at 20 DAS + One hoeing at 30 DAS (T 4)
which was found significantly superior over rest of the treatment.
Mean gross monitory return of French bean was Rs.79609 ha -1 . The gross monetary return
(Rs ha -1 ) of French bean was differed significantly due to different weed control treatments.
The weed free treatment (T 6 ) recorded significantly maximum gross monetary (Rs 950000 ha -
1 ) which was at par with Pendimethalin 30% EC @1.0 kg a.i. ha -1 (PE) + One hoeing at 30 DAS
(T3) and Quizalofop-p-ethyl 5% EC 100 g a.i. ha -1 at 20 DAS + One hoeing at 30 DAS (T4)
and found significantly superior over rest of the treatments.
The mean net monetary return of French bean was Rs. 41728 ha -1 . The net monetary return
was influenced by significantly due to different treatments. The application of Pendimethalin
30% EC @1.0 kg a.i.ha -1 (PE) + One hoeing at 30 DAS (T 3) recorded significantly higher net
monetary return Rs.54850 ha - 1 which was at par with Quizalofop-p-ethyl 5% EC 100 g a.i. ha -
1
at 20 DAS + One hoeing at 30 DAS (T 4) and weed free treatment (T 6) and found significantly
superior over rest of the treatment. The application Pendimethalin 30% EC @ 1.0 kg a.i. ha -1
(PE) + One hoeing at 30 DAS (T3) recorded higher B:C ratio (2.52) of French bean which was
closely followed by Quizalofop-p-ethyl 5% EC 100 g a.i. ha -1 at 20 DAS + One hoeing at 30
DAS (T 4) with B:C ratio 2.47.
Conclusion
Considering growth, yield, economics, it could be concluded that application of Pendimethalin
30% EC @ 1.0 kg a.i. ha -1 (PE) + one hoeing at 30 DAS (T 3) or application of Quizalofop-pethyl
5% EC @ 100 g a.i. ha -1 at 20DAS + one hoeing at 30 DAS (T4) were more effective in
French bean.
