Irrigation should be scheduled as under:
a. First irrigation of 80 mm on the day of sowing.
b. Second irrigation of 50 mm 17 days after first one.
c. Third and fourth irrigations of 50 mm at an interval of 13-14 days.
d. Remaining three irrigations of 50 mm at an interval of 10 days.(The sprinklers spaced at 12m x 12m need be operated for 5 hours to get 80 mm depth and 3 hours for 50 mm depth at a pressure of 2.75 kg cm-2 ).

4. Irrigation scheduling based on critical growth approach in wheat.
Farmers growing wheat variety Lok-1 in AES-IX of Middle Gujarat Agro climatic Zone under constraints of irrigation water are advised to give four irrigations each of 80 mm depth instead of the recommended seven irrigations. The first two irrigations should be given at post sowing and crown root initiation. Next two irrigations should be given at tillering and panicle initiation or flowering or milky stages. They can also irrigated other two irrigations at panicle initiation and milking or flowering and milking or panicle initiation and dough stages.

They should lay out the drip system as one lateral for each crop row (75 cm) with 3 LPH dripper placed at a distance of 120 cm (one dripper in between two plants). The system should be operated 120 kPa pressure for 2 hr. and 30 min. on alternate day during October to January and 3 hr. and 40 min. during February and March.
Under extreme shortage of water they should operate the system along with plastic mulch for 1 hr & 15 minutes (0.5 FPE) during October to January and 1 hr and 50 minutes during February and March on alternate days to bring an additional 1.3 ha area under cultivation of brinjal and can get about 25% increase in the net return for the same quantity of water used as in the surface.
(1996)
12. Water requirement and irrigation scheduling in brinjal.
The farmers of the AEX-IX of Middle Gujarat Zone growing brinjal in deep black soil of Narmada Command are advised to apply twelve irrigations each of 80 mm depth.
