Drip irrigation layout for one acre of banana, worked

This is a drip irrigation layout for one acre of banana, worked end to end on one set of honest assumptions — so you can copy it, argue with it, or hand it across our counter and say "this, but my field". Every measurement is stated, every part is priced at our own MRP, and the places where your farm will differ are flagged rather than hidden.

If you are still deciding whether banana gets drip at all, that case is made separately. This page assumes yes and draws it.

The field this sheet assumes

A square acre, 64 by 63 metres, flat enough to ignore slope. Rows at 1.8 metres — the tight end of banana spacing — running the 63 metre direction. That gives 35 rows, and the layout follows in three strokes:

Rows run the long way so laterals stay under 70 metres — comfortable for even dripping — and the spine stays short. If your field is a rectangle rather than a square, keep that rule: laterals along the length, spine across the width.

• 35 laterals, one per row, each 63 metres, fed from the same end
• one sub-main across the 64 metre row-end boundary, pump corner to far corner
• the pump connection, non-return valve and one control valve at the head

The laterals: 2,205 metres, five coils

Thirty-five rows of 63 metres is 2,205 metres of lateral. In the 16 mm, 0.4 mm-wall flat lateral — the working banana grade — that is five 500-metre coils at ₹3,366: **₹16,830**, with about 295 metres left over for the odd corner, future gap-filling and honest mistakes.

Fittings count themselves: one ₹6 takeup and one ₹6 end cap per row. Thirty-five of each means the boxed hundred of both (₹600 + ₹600 = **₹1,200**), which is also the online ordering floor — the spares are not waste, they are the next three years of repairs, plus the joiners that ride along at ₹6 when a line needs a mend.

A word on the emitters this sheet assumes. The flat lateral's built-in drippers sit at a fixed interval, so each banana mat is served by the several emitters wetting its stretch of row — the strip they soak joins up underground, and the plants drink from the shared band. Growers who prefer water placed exactly at every mat, added to as it grows, swap this one line of the sheet for the online-pattern lateral; the metres, spine and bill structure all stay the same.

The spine, the head, the valve

The sub-main has one job: carry the whole flow 64 metres with pressure to spare. A 3-inch LDPE coil does it — the 15 kg, 90-metre coil at **₹2,160** covers the boundary run and the stub to the pump stand.

One ball valve at the head is the minimum. Fit two — splitting the block into 17 and 18 rows — if your pumping hours are short, and the next section says whether they are.

At the head, two parts are non-negotiable and priced here: the 2-inch ball-type non-return valve (**₹1,440**) so shutdowns do not drain the line back down the bore, and the 2-inch SS HDPE connector (**₹558**) where steel meets plastic. The bends, nipples and solvent tin that complete a real head vary by pump stand — the pump-to-lateral walk-through prices that chain part by part.

Pump duty, in hours

Banana at peak drinks 5 to 8 mm a day. Over an acre that is roughly 20,000 to 32,000 litres landing in the root zone daily, and on drip's efficiency the bore must lift a little more — call it 22,000 to 36,000 litres in the hard weeks.

Divide by your bore's honest yield: at 3,000 litres an hour, that is seven to twelve pumping hours a day at peak. If your reliable power window will not hold that, the two-valve split above is not an option but the design — each half waters on alternate slots, and the water requirement calculator will re-run these figures for your own acreage and bore before you commit.

The bill, added up

That is **₹22,188**, MRP with tax inside, checkable line by line on the drip and LDPE ranges. It excludes the head's small steel, the filter — which banana's long season makes essential and we plainly do not stock — freight, and the pump side itself. Budget those honestly and the sheet still lands well under the round numbers quoted for "banana drip" in the market.

• Laterals — five coils, 16 mm × 0.4 mm flat: ₹16,830
• Takeups and end caps — a boxed hundred of each: ₹1,200
• Sub-main — 3" LDPE, 90 m coil: ₹2,160
• Non-return valve, 2" ball type: ₹1,440
• SS HDPE connector, 2": ₹558

If your field is not this field

Three dials move this sheet. Wider rows at 2.1 metres drop you to 30 laterals and four coils. A long thin field stretches the spine, not the laterals — upsize the sub-main before anything else. And a weaker bore changes run-time, not pipe: more valves, same metres.

The system estimator redraws all of it from your crop and acres in a minute, and the banana crop page keeps the agronomy beside the parts. If your patta says something other than a tidy square — most do — send the real measurements and we will return this same sheet with your numbers in it, priced and counted, before any coil ships.
