Irrigation Management of Okra

Irrigation Management of Okra:-

First irrigation should be given when first true leaf initiates in springs summer and when it expands in Kharif season.
Subsequent irrigations at 4-5 days Intervals are given to summer crop.
If temperature goes around 40 ⁰C frequent light irrigation are recommended for proper fruiting.
The soil should be kept moist and flooding or wilting of plants should be avoided.
Moisture stress during flowering and fruit/seed setting causes around 70% crop losses.
The nutrient uptake from soil is also at peak during fruit set and development stage.
A water stress in the field during this period not only cause yield reductions but also affects the nutritional status of the fruits.

Keeping a potato crop at optimum moisture levels for the duration of the season requires a high degree of management.
There are certain stages of growth where water management is more critical:
1) Emergence Stage
2) Tuber set Stage
3) Bulking up Stage
4) Final crop Stage
5) Pre-harvest irrigation Stage.

For proper germination, pre-sowing irrigation is a must if the soils are dry.
Normally 2-3 irrigation is needed for midseason peas or late sown peas.
Moisture stress at flowering and subsequent pod filling stage are most undesirable affecting the yield and quality of pods.

Repeat irrigation 3 days after for ensuring germination.
Irrigate as per need.
Thereafter irrigate ones in a week during the vegetative phase and 10-15 days during bulb development
Avoid irrigation during bulb maturity. Irrigate 2-3 days before harvest to facilitate easy uprooting.

During summer, irrigate the crop every week.
The irrigation should be as light as possible.
At the time of fruit maturity water should be given when it is very necessary.
Overflooding should be avoided as the fruit oncoming contact with moist soil gets spoiled.

Cowpea is sensitive to waterlogging and requires less moisture compared to other vegetables.
Grain types require only 2-3 protective irrigations at flowering and pod development stages.
Water requirement of vegetable type with protected and long fruiting phase is more than grain types.
Harden plants by restricting irrigation during pre-flowering stage.

First irrigation should be immediate after sowing and second irrigation is about 5 to 6 days after sowing.
After 10 days interval, or as per need.
The first irrigation should be done after hand weeding and apply urea 40 kg/Acre.

Timely irrigation is quite essential for good growth, flowering, and development of fruits.
Light irrigation is given at an interval of 8-10 days during winter and 5-6 days during summer.
During winter keep the soil moist by light irrigation to protect crop from winter injury.

Drip irrigation

Install drip system with main and sub-main pipes and place the inline lateral tubes at an interval of 1.5 m. Place the drippers at an interval of 60 cm and 50 cm spacing with 4 LPH and 3.5 LPH capacities respectively.
