while have plant density equal to 32 000 plants per ha, and row width equal to 0.91 m
Dear Camile, you may calculate plant to plant distance within each row in following way:
Desired plant density=32000 per hectare
1 hectare area=100 m length x 100 m width (considering square shaped field)
As row width=0.91 m, Total number of rows=100/0.91=110
Number of plants per row=32000/110=291
So, plant to plant distance in a row=100 m/291=0.34 m
Calculation of equidistant plant spacing Example problem
Theoretically, the best utilization of light, water, nutrients, and space by individual plants in a crop stand occurs when plants are equal distance from each other in all directions. This distance, known as the equidistant plant spacing, can be easily calculated using the stand density for the crop and the following equation:
Equidistant spacing (in inches) = [sqr root (43,560 ft2 per acre / stand density)] x 12 inches
where stand density is in plants per acre
What is the theoretical optimum row spacing if you are planting a crop at 30,000 plants per acre?
Since we want equal distance between all plants in the stand, our row spacing will be the same as the spacing between adjacent plants in the row. Therefore we can use the equation for equidistant spacing to determine the theoretically optimum row spacing.
Equidistant spacing = [sqr root (43,560 ft2 per acre / 30,000 plants per acre)] x 12 inches
Dear Camile, you may calculate plant to plant distance within each row in following way:
Desired plant density=32000 per hectare
1 hectare area=100 m length x 100 m width (considering square shaped field)
As row width=0.91 m, Total number of rows=100/0.91=110
Number of plants per row=32000/110=291
So, plant to plant distance in a row=100 m/291=0.34 m
Intra-row distance = (1 hectare / plant population per hectare)/row width
(10000/32000)/0.91 = 0.3434m
Plant population per square meters=10000 cm2 / (row space ×plant space)
Plant population per square meters= 10000 m2/32000=3.2m2
3.2=10000cm2/ (91cm×plant space)
Plant space=10000/ (3.2×91)
Plant space=34.34cm or 0.34m
To calculate the inter row plant theoretically must be retain to the feeding system motion. If feeding system having motion relative to land wheel or alone motion.
In such situations, I suggest we use this (if your measurements are in cm)
Number of plants per hectare = 100 000 000/(intra-row cm x inter-row cm)
