Paired-Row Planting & Keep the Population, Open a Lane
Lays out sugarcane
Pairing two close rows with a wide walkway between pairs keeps the population while opening a lane for drip, intercrops and machinery — enter the pair, walkway and plant spacing to get plants per hectare, plants per m², rows per metre and total plants.
Lay out paired rows
Next: set out 47,059 plants as paired rows 0.5 m apart with a 1.2 m walkway between pairs — the wide aisle keeps spray, light and access while the close pair holds population at 47,059/ha.
Paired-row (twin-row) layouts cluster two close rows then leave a wide walkway, repeating; they preserve plant numbers while easing inter-row operations and airflow.

Two crops worth of access without losing the stand
Paired-row planting groups the crop into close twin rows with a wide walkway between each pair. The close pair keeps plants near their neighbours so the canopy and yield hold up, while the walkway becomes a clear lane for a drip lateral, an intercrop, a sprayer or a harvester. Set the pair and walkway so the average row spacing matches your normal single-row spacing and the population is unchanged — you have simply rearranged the rows to buy yourself access and light.
This tool returns the plants per hectare, plants per m², rows per metre and the total plants for your pair spacing, walkway and plant spacing, across acre, hectare, guntha, bigha or m². Use it to design a twin-row layout, to check the population against single rows, and to plan an intercrop in the lane. Pair it with the Triangular Planting Density, Plant Population Yield Response and Field Establishment tools for the full stand picture.

Frequently Asked Questions
How is the paired-row population calculated?+
Each pattern is one close pair plus one walkway, so the pattern width is the close-pair spacing plus the walkway spacing, and it holds two rows. Rows per metre is 2 ÷ that pattern width, plants per m² is rows per metre ÷ the plant spacing along the row, and plants per hectare is that times 10,000. Multiplying by your field area gives the total plants.
What is paired-row (twin-row) planting?+
Paired-row planting groups the crop into close pairs of rows with a wide walkway between each pair, instead of evenly spaced single rows. The close pair keeps plants near their neighbours for canopy and yield, while the walkway opens a clear lane for intercropping, drip lines, spraying and machinery. It is common in sugarcane, maize, cotton and many vegetables.
Why use a wide walkway between pairs?+
The walkway is the whole point: it lets you run a drip lateral down the gap, intercrop a short companion crop, move a sprayer or harvester through, and get more light and air to the canopy edge. By pairing rows close together you keep the plant population up even though you have given up a wide lane, so you trade little or no density for a lot of access.
Does paired-row spacing change my plant population?+
It can. If you set the close-pair spacing and walkway so the average row spacing matches your normal single-row spacing, the population is unchanged — you have just rearranged the rows. Make the walkway wider than that and the population falls; make the pair tighter and it rises. The tool shows the exact plants per hectare for whatever pair and walkway you enter.
What spacings should I enter?+
Enter the spacing between the two close rows of a pair, the spacing of the wide walkway between pairs, and the plant-to-plant spacing along the row — all in metres. For example, sugarcane is often paired at around 0.3 m within the pair and 1.2 m between pairs. Use the figures your crop and equipment need and the tool returns the matching population.
How does this help with intercropping?+
The walkway is exactly the space an intercrop occupies, so once you know your paired-row layout you know the lane width and length available for a companion crop. Pair the population this tool gives with an intercropping land-equivalent calculation to plan two crops on the same field. The wide lane is what makes the system productive rather than wasted ground.
Does it work for any crop?+
Yes — sugarcane, maize, cotton, pigeonpea, tomato and many vegetables are grown in paired rows. Only the pair spacing, walkway and plant spacing change by crop and machinery. Enter the three spacings and your area and the population calculation holds for any of them.
Are the figures exact?+
They are exact geometry from your spacings — rows per metre, plants per m² and plants per hectare follow directly. The total plants assumes a full, uniform stand, so real numbers fall a little once you allow for emergence loss and headlands. Use the Field Establishment tool to convert this seeded population into the stand you will actually count.
