Irrigation and scheduling

Irrigations should be done at right time and in adequate quantity. Recommended time of irrigation is as below:

    1^st Irrigation : At crown root stage i.e. 20-25 days after sowing

 Row to row distance and depth of seeding

Important Points for Ensuring High Wheat Yields

1. Timely sowing

2. Use of region specific recommended varieties

3. Balance dose of fertilizer should be used on the basis of soil testing. 

4. Timely irrigation

5. If zinc sulphate has not been used in previous crop then it should be applied at the time of sowing.

Yellow Ear rot or Bacterial Rot

Causal Organism: Corynebacterium tritici

Chief symptoms: Yellow exudate on the spikes is indicative of bacterial diseases .When dry, the exudates is white to yellow white .often the spikes and necks will emerge as a distorted sticky The early leaves may also be wrinkled or twisted

Control measures:

• Tillers: The tillers have the same basic structure as the main shoot. These arise from the axils of basal leaves. At anthesis most of the tillers bear productive ears, however, a few remains sterile.
• Spikelet : Spikelet is compose of the flowers called florets.  The number of floret in a spikelet may vary from 1-5.  The floret in rach spikelets are enclosed by two glumes.

 Introduction

50-60% humidity is optimum for wheat crop. If relative humidity is less than this then moisture loss occurs due to heavy evapo-transpiration and it results in more water requirement for irrigation. Disease infestation increases when there is high humidity coupled with high temperature.

Wheat is cultivated in the region where annual precipitation occurs from 25 to 175 cm, though 75% wheat area falls where annual rainfall precipitation occurs between 37.5 to 87.5 cm. Region with 62.54 to 87 cm rainfall are most suitable for wheat cultivation and out of this 10-15 cm rainfall is required when crop is in the field. Rainfall and snowfall at the time of maturity cause severe loss to wheat crop affecting yield and seed quality adversely.
