Throughout the world, emphasis is being given

for efficient utilization of harvested rain waterby reducing deep percolation losses andmaximizing benefits from the use of availablewater resources for assured crop production.One such popular way is by changing fromtraditional flood irrigation methods to mostefficient micro irrigation methods likesprinkler or drip irrigation systems.

In Himachal Pradesh, about 19 per cent of the cultivatedarea has assured irrigation facilities which are generally

occupied for vegetable cultivations. Even after exploitationof all the water sources for irrigation in Himachal Pradeshit has estimated that not beyond 40 of the total cultivablearea can be brought under irrigation. Thus at that stage, 60per cent of area will always remain rainfed (IPH).

Harvesting rain-water in small or big ponds is a commonfeature in hills to sustain vegetable as well as other H VCash Crops production.

Scientific information on efficient utilization of harvestedrain-water in relation to soil water retention and

transmission characteristics and atmospheric demandneeds to be generated.

Focus should not only be on profitable crop yields butalso on higher water and nutrient use efficiency .

Functions as its name suggests, water isdelivered at near the plant, drop by drop.Slow application of water in the form of discreteor continuous small droplets throughmechanical devices called emitters.Efficient method of providing irrigation water andfertilizers near the plants.Permits the utilization of fertilizers, pesticidesand other water soluble chemicalsThe gravity-fed drip irrigation system willovercome the costs on account of pressurizedunit required in general and power supplyrelated requirements

The test crop broccoli has a special

significance for Himachal Pradesh asit is coming up as a cash crop.The cultivation of broccoli is being

promoted keeping in view itsmedicinal value and market demand.Broccoli is high in vitamins A, C andK as well as dietary fiber; it alsocontains multiple nutrients withpotent anti-cancer properties.

The irrigation will be applied through gravity fed drip irrigationsystem installed at 60 x 45 cm spacing.The drip system will be operated daily for initial 15 days andthereafter on alternate days.In NPK fertigation treatments, water soluble fertilizers viz.,19:19:19 + 0:0:50 + urea will be applied in different calculatedproportions injected through overhead fertilizer tank at 8- 10

days interval in 8-10 splits.In fertilization treatment (Control), half of N and whole P andK will be applied at transplanting and remaining 50% N will beapplied in two equal splits, one after 30 days of transplantingand second at curd initiation stage.Recommended FYM dose will be applied as per practice. Inaddition, three absolute control plots will also be kept fordetermination of fertilizer use efficienc y.
