Get cassava spacing wrong on one acre, and you either waste hundreds of cuttings or leave your land underplanted. The right number depends on your variety, and it is not the number most farming articles actually give you.
I plant cassava at 1 meter by 1 meter spacing on my farm, and that number only tells part of the story.
Spacing depends heavily on your variety’s growth habit, since branching and upright types need different amounts of room, and getting the land math wrong can throw off an entire planting season’s cutting order.
This guide covers the standard spacing recommendation, how variety and soil conditions change that number, and the correct cuttings-per-acre calculation, since a commonly repeated figure online is actually a unit conversion error.
You will also find real field data showing how spacing choices affect cassava root yield.

Why Spacing Decisions Matter More Than One Number
Spacing sits within the wider cassava planting process, alongside cutting selection, soil preparation, and timing.
Get spacing wrong, and every other planting decision gets harder to correct later.
The sections below cover the standard recommendation, the real variety-specific adjustments, and the land math farmers actually need.
Standard Cassava Spacing: 1 Meter by 1 Meter
The standard recommendation for cassava grown for root production is 1 meter between plants and 1 meter between rows, producing roughly 10,000 plants per hectare.
This spacing comes from IITA’s cassava cropping guide, the most widely cited agronomic reference for the crop.
The spacing gives each plant enough room for root expansion, airflow, and sunlight without wasting land on excess gaps.
This figure works as a solid default, though the sections below cover when it should change.
Branching vs Non-Branching Varieties Need Different Spacing
Not every cassava variety needs the same spacing, since growth habit changes how much room a plant actually requires.
Branching varieties need the full 1m by 1m spacing to avoid overcrowding their wider canopy.
Non-branching, upright varieties can be planted closer, around 0.75m by 0.75m, according to Wikifarmer’s cassava propagation guide.
Planting an upright variety at branching-variety spacing wastes usable land without any yield benefit.
Check with your seed source or local extension office to confirm which growth type your variety follows before finalizing spacing.
What Real Field Trials Show About Spacing and Yield
Spacing decisions have a measurable, tested effect on yield, not just a theoretical one.
A Brazilian field trial testing four interrow spacings, 60cm, 80cm, 100cm, and 120cm, found plant populations ranging from 27,778 down to 13,889 plants per hectare.
That research, published and indexed on ResearchGate, found that wider interrow spacing reduced the crop’s stem green mass in a clear linear pattern.
This confirms that spacing is not a fixed universal rule, since actual field results shift meaningfully across a fairly narrow range of distances.
Farmers experimenting with spacing should track yield per plant, not only yield per hectare, to judge the real tradeoff.
How Many Cuttings Do You Actually Need?
For a hectare planted at 1m by 1m spacing, the correct figure is 10,000 cuttings, since one hectare equals exactly 10,000 square meters.
For one acre at the same spacing, the correct figure is approximately 4,047 cuttings, not the 4,840 figure that circulates on several farming sites.
That higher number actually describes an acre’s size in square yards, not square meters, a common unit mix-up.
One acre equals roughly 4,046.86 square meters, which at 1m by 1m spacing supports about 4,047 plants.
Order cuttings based on the corrected figure to avoid paying for several hundred more than your land can actually hold.
Environmental and Soil Factors That Adjust Spacing
Soil fertility changes how tightly cassava can be planted without competing plants stunting each other.
Fertile soils can support closer spacing, since nutrients are less likely to run short across a dense planting.
Poorer soils generally need wider spacing so each plant can draw enough nutrients from a larger root zone.
Read our guide on soil requirements for cassava covers, texture, and fertility needs in more depth.
High humidity and frequent rainfall also call for wider spacing, since tighter plantings trap moisture and raise the risk of fungal disease pressure.
Spacing for Stem Multiplication vs Root Production
Farmers growing cassava purely to multiply planting material for the next season need much tighter spacing than root farmers.
A 0.5m by 0.5m grid maximizes stem output per unit of land, since a single plant’s root size matters far less in a nursery block.
This distinction, drawn from the same Wikifarmer propagation guide, gets left out of most spacing articles entirely.
Mixing up these two goals leads to either wasted nursery space or undersized roots at harvest.
Decide which outcome you are planting for before choosing a spacing grid.
Putting It Into Practice
A few practical steps turn spacing knowledge into a real planting plan.
- Confirm your variety’s growth habit, branching or upright, before finalizing your spacing grid.
- Calculate cuttings needed using 10,000 per hectare or roughly 4,047 per acre as your baseline.
- Adjust wider in humid, high-rainfall areas and tighter in well-drained, fertile plots.
- Order cuttings only after confirming your actual land area in square meters, not estimated acres.
Our guide on cutting cassava stems covers selecting and preparing planting material for this exact spacing plan.
A companion guide on preserving cassava stems for the next season covers storage between harvest and planting.
Timing your planting around the best time to plant cassava matters just as much as getting the grid right.
If you plan to grow a companion crop alongside cassava, our guide on intercropping with cassava covers how that changes row spacing.
Final Word From Cassava Pathway
Cassava spacing is not a single fixed number, despite how frequently it gets presented that way.
Your variety’s growth habit, your soil fertility, and your actual goal, root production or stem multiplication, all change the right answer for your field.
I still use 1 meter by 1 meter as my default in Ntigha, but I adjust it tighter or wider depending on which variety I am planting that season.
Before your next planting cycle, confirm your land area accurately and order cuttings based on the corrected acre figure above, not the inflated one still circulating online.
Frequently Asked Questions
What is the standard spacing for cassava?
The standard spacing for root production is 1 meter between plants and rows, producing roughly 10,000 plants per hectare for most branching cassava varieties.
How many cassava cuttings do I need per acre?
At 1m by 1m spacing, one acre needs approximately 4,047 cuttings, since an acre equals about 4,046.86 square meters, not 4,840.
Does spacing change for branching cassava varieties?
Yes, branching varieties need the full 1m by 1m spacing, while non-branching upright varieties can be planted closer, around 0.75m by 0.75m instead.
Can closer spacing increase my total cassava yield per hectare?
Closer spacing raises plant count per hectare, but field trials show it can reduce yield per single plant, so the total tradeoff varies by variety.
