How to flower promotion in chickpea

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.

Calcium is an important nutrient in garlic and has a key role to play in crop yield and quality.
Calcium promotes enhance of root establishment and elongation of cells resulting in increasing plant height.
It also has a improve tolerance of disease and chilling injury.
Although the recommended dose of calcium in the Garlic is good for yield, quality, and storage capacity.
The recommended dose of calcium is 4 Kg/Acre or according to soil testing report.

Termites damage the crop soon after sowing and sometimes near maturity.
They feed on roots, stems of growing plants, even dead tissues of plant-feeding on cellulose.
The damaged plants dry up completely and are easily pulled out.
The plants damaged at later stages give rise to white ears.
Infestation is heavy under unirrigated conditions and in the fields where un-decomposed farmyard manure is applied before sowing.

Avoid late sowing.
Avoid using excessive nitrogen fertilizers.
If the infestation in standing crop, Spray imidacloprid 17.8% SL @ 60-70 ml/acre.
Or apply thiamethoxam 25% WG @ 100 gm + beauveria bassiana 2 kg/acre in soil with fertilizer/Sand/soil before irrigation.

This insect is active from November to February.
Damage is more in the rainfed and late sown crop.
The yellowing of young plants is observed due to root aphids.
In this case minute, yellowish-brown aphids may be present near the base or on the roots of the plant.
Aphids also vector a viral disease name barley yellow dwarf virus (BYD). The yield of infected wheat plants can be reduced by 50%

Apply light irrigation in the evening on the leaves of the plants.
Every year, the use of small amounts of sand in the field reduces the effect of frost in crops.
Dry weed and dry wood burning in the opposite direction of the wind also reduce frost.
Irrigate after spraying Sulfur 90% WDG powder in 3 kg/ acre.
Spray Sulfur 80% WDG powder by mixing it at 40 grams/pump (15 liters of water)
spray pseudomonas fluorescent 1 kg per acre.

Adults are small black and yellow flies.
Larvae exit from the leaf upon completion of their development and pupate in the soil or in the leaf axils on plants.
Females puncture the leaf to feed plant sap and lays eggs within the leaf tissue.
The damage restricts the plant growth, results in reduce bulb yield and loss of vigor.
Tunnels or mines can be seen in the leaves.
