Water and Weed Management in Wheat Crop | Wheat Field | Krishi Network

Описание: Water management:
Crown root initiation and heading stages are the most critical to moisture stress. Four to six irrigations are enough for wheat crop. Depending upon the water availability, these should be applied as per the requirement of the crop.

In case of zero tillage, irrigation scheduling similar to conventional tillage may be followed.
In FIRB system, first irrigation may be applied immediately after sowing for proper germination.
Use clean wheat seed that is free from weed seeds, sow early and adopt closer row spacing for better weed control.

Weed management:
Apply Pendimethalin @ 1000 g/ha at 0-3 days after sowing in 500-600 litres of water/ha as pre-emergence.
For control of mixed weed population Sulfosulfuron @ 25.0 g/ha in 250-300 litres of water/ha can be sprayed at 30-35 days after seeding. In resistance free area, combination of 2,4-D @ 500 g/ha and isoproturon @ 750 g /ha can also be used.
For control grassy weeds only Clodinafop @ 60 g/ha or Fenoxaprop-ethyl @ 100 g/ha) in 250-300 litres of water/ha should be applied.
If only broadleaved weeds are present then apply 2,4-D @ 500 g/ha or Metsulfuron methyl @ 4 g/ha in 250-300 litres of water/ha.
