Bamboo Plantation & Clumps & Pole Yield

It turns your plot area and spacing into a planting and harvest plan: how many clumps you need to plant, the area each clump occupies, the annual poles (culms) a mature stand produces, and how many of those culms you can safely cut each year. It saves you guessing seedling numbers and over-estimating early yield.

Bamboo is planted in clumps at a fixed spacing — commonly 5×5 m. At 5×5 m each clump claims 25 m², so an acre (≈4047 m²) holds roughly 160 clumps and a hectare about 400. Wider spacing for big timber species means fewer clumps; tighter spacing for small ornamental or edible bamboo means more.

Area per clump = row spacing × plant spacing. Clumps = plot area ÷ area per clump. So a 1-acre plot at 5×5 m gives about 4047 ÷ 25 ≈ 160 clumps. Use the same plot area unit throughout — the tool handles acres, hectares, bigha, guntha or m² for you.

A clump yields little in the first couple of years while it establishes its rhizome system. It typically reaches steady, harvestable production once mature — usually around 3–4 years after planting — after which a healthy clump throws several new poles (culms) every year.

A mature clump produces several new culms per year, often in the range of 8–20 depending on species, soil, water and management. The tool multiplies your culms-per-clump figure by the number of clumps to give the stand's total annual pole production.

Only a fraction of the culms is cut each year to keep the clump healthy — commonly the older, mature culms while younger ones are left to grow. Harvesting roughly the same number that the clump regrows keeps the stand in balance. The tool applies your chosen harvest share to show harvestable poles per year.

Clear-cutting a clump removes the photosynthesis and food reserves the rhizome needs to push next season's shoots, so yield collapses and the clump can die back. Selective harvesting of mature culms only — leaving young and current-year poles standing — keeps the clump vigorous and productive for decades.

It depends on species and purpose. Large timber and construction bamboos are usually planted at 5×5 m or wider so big clumps don't crowd; smaller edible-shoot or ornamental bamboos can go tighter at 3×3 m or 4×4 m. Tighter spacing gives more clumps and faster canopy but more competition at maturity.

Yes — enter the plot area in acres, hectares, bigha, guntha or m² and the spacing in metres, and the tool scales the clumps, area per clump and pole figures accordingly. It works equally for a backyard stand or a multi-acre commercial plantation.

They're planning figures. Real culm numbers vary with species, age of the clump, soil fertility, irrigation, climate and how well the stand is thinned and managed. Use the output to size your planting and budget, then adjust against what your own clumps actually produce after a few seasons.
