Count the plants in 5 metres of row and see how many plants there are per hectare and what that represents of the target population.
Pre-sizing and estimating tool: the results do not replace a design, calculation, or report signed by a qualified professional, nor verification against the applicable standards.
Thousands of plants per hectare for counts of 50 to 100 plants over 5 m; the highlighted bar is yours.
Thousands of plants per hectare at each spacing, with your count; the dashed line is the desired population.
Drag the controls to simulate data different from what you entered (from 30% less to 30% more) and watch the result change instantly.
Plants per hectare and stand for counts of 40 to 80 plants in 5 m, with the spacing and population you entered.
The calculation done in steps, with the values you entered.
The calculation memo gathers this page's inputs, results, equations, assumptions, and references, with fields for project, responsible person, and review. The full report also includes the charts and interpretations, in color. In the print window, choose Save as PDF.
Count the plants in 5 metres of one row, at three to five points in the crop. Enter the row spacing in centimetres and the target population. The calculator shows plants per metre, per hectare and the plant stand.
65 plants in 5 m of row, 50 cm spacing and a target population of 300 thousand plants/ha.
Plants per meter = 65 ÷ 5 = 13. Plants per hectare = 13 × (10,000 ÷ 0.5) = 260,000 = 260 thousand/ha. Stand = 260 ÷ 300 = 86.7%.
Because it is an easy stretch to measure in the field and represents the population well. Count at least 3 to 5 points in the crop and take the average.
No. Population is the target (how many plants you wanted). Stand is how much of it was achieved in the field.
Check the seed, germination, depth and planter setting, the soil and the weather right after emergence. Replanting is only worth it if done early.
Because with the same plants per meter, narrower rows mean more plants per hectare. That is why spacing is part of the calculation.
Important notice: the Agrocalcs tools make estimates and preliminary sizing based on the data entered and on published engineering methods. They do not replace a design, a calculation report or a report signed by a qualified professional (CREA/ART), nor verification against the applicable technical standards and legislation, such as the Regulatory Standards of the Ministry of Labor.
