Significant Findings Pre-kharif Black gram and Green gram PE herbicides recorded higher WCE over POE herbicides
30 DAS -- 19.31 and 15.28 %
50 DAS - 10.72 and 11.29 %
Kharif Direct seeded puddled and Transplanted paddy Direct seeded puddled paddy (DSPP) POE herbicides better WCE over PE herbicides : 8.54 and 7.17% more WCE
PE herbicides - 55.71 and 42.52 % WCE at 30 and 50 DAT, respectively
POE herbicides - 64.25 and 49.69 % WCE at 30 and 50 DAT, respectively
Transplanted paddy (TRP) PE herbicides better WCE over POE herbicides : 2.82 and 2.61% more WCE
PE herbicides -69.08 and 53.16 % WCE at 30 and 50 DAT, respectively
POE herbicides -66.26 and 55.77 % WCE at 30 and 50 DAT, respectively
Rabi Potato and Onion
Potato PE herbicides 20.03 and 24.24 % more WCE over one POE herbicide
PE Herbicides 92.40 and 66.27 % WCE at 30 and 50 DAP, respectively
Onion PE herbicides - 13.30 and 9.29 % more over POE herbicides
PE herbicides -61.90 and 43.96 % WCE at 30 and 50 DAP, respectively
Pre-kharif Black gram and Green gram PE herbicides recorded higher number of pods 3.35 and 3.45 over POE
HW - Maximum number of pods 14.9 (BG) and 15.87 (GG) and
Weedy check - Minimum number of pods 9.33 (BG) and 10.33 (GG)
Kharif Direct seeded puddled and Transplanted paddy HW - Maximum 12.87 (DSPP)and 16.45 (TRP) number of panicles/plant
Weedy check -Minimum 9.90 (DSPP) and 12.67 (TRP) no. of panicles/plant
PE herbicides - 12.38 (DSPP) and 15.37 (TRP) number of panicles/plant
POE herbicides - 11.00 (DSPP) and 14.52(TRP) number of panicles/plant
PE herbicides -More over POE herbicides : 12.55 % (DSPP) and 5.85% (TRP)
Rabi Potato and Onion
Potato PE herbicides (59.03 g) -10.93 g more tuber weight over POE (48.10 g)
HW- 59.0 g tuber weight and Weedy check - Mminimum 40.33 g
Onion PE herbicides (41.00 g) - 6.61 g more bulb weight over POE (30.87 g)
HW – Maximum bulb weight (44.7 g) and weedy check -Minimum (35.33 g)
Soil microflora population
Following Annual Planning of
Weed Pest Management (APWPM)
PE Herbicides recorded
more WCE, better major yield attribute,
higher economic yield and
superior soil microflora population
in comparison to POE herbicides
in all the crop sequences of
Black/Green gram (Pre- Kharif) –
DSPP / TRP (Kharif) –
Potato / Onion (Rabi)
