Before discussing how to calculate seed needs correctly, it’s a good idea to know the cultivation components related to seed needs.
Plant Cultivation Components
Below are several important components in the plant cultivation system that you should know:
Seeds
The definition of seed is a plant seed that will be used and grown into seeds and of course the results will be taken.
In the opinion of experts, seeds are the result of generative reproduction. However, other opinions can result from generative or vegetative processes.
Meanwhile, the general definition of seeds is the term used by farmers for basic materials in plant maintenance.
The important thing for calculating seed needs is information on the weight of 1000 seeds. To find out, you can count and weigh the weight of 1000 seeds.
If you don’t have a scale, you can use the method of estimating the number of seeds in a package, for example the number of cucumber seeds in a 25 gram package containing 800 seeds, then from that information we can calculate the weight of the 1000 seeds.
Quantity information is usually stated on the packaging, but if it is not available, we are forced to count the number of seeds manually.
2. Land area
Information on land area is needed because planting is carried out on the field that will be planted with planting distances.
The results of the division are the number of plant populations. The size of land area varies, especially in units and sizes.
Whatever units are used, local units need to be converted to standard units such as m2.
3. Planting distance
So that land production can produce high levels of production, the most important thing that must be considered is the spacing of plants.
The definition of plant spacing is the size and size of the space between one plant and another plant can also be in a row of plants.
Be aware that plant spacing can apply if we plant plants on land or also use certain containers, for example using polybags.
Plant spacing is used to determine the number of plant populations in an area. Regular plant spacing can make the cultivation process easier.
Plant spacing without a fixed size causes the need for seeds to be different for each planting, for example 1 hectare last season required 15 kg of corn seeds, but this season it reaches 20 kg of seeds.
Plant spacing is one of the keys to successful cultivation. Planting with too close a spacing is at risk of disease attacks because dense populations cause increased humidity.
Plant spacing that is too sparse makes productivity less than optimal. Therefore, we need to know the ideal planting distance for each variety.
4. Growth Power
Each plant variety sold commercially has information on growth capacity in %.
In calculating seed requirements, information on the growth capacity value is used to ensure the number of seeds that can grow when planted and determine the number of seeds needed for replanting.
How to Calculate Seed Needs
Then how to calculate seed needs, here is the explanation:
The formula for calculating seed needs:
Information :
- Area calculations use the same units as standard units.
- Land area in hectares converted to m2 multiplied by 10,000.
- Plant distance in cm units converted to meters.
- By dividing the land area and planting distance, we produce the number of planting points.
To get a 100% planting point without anyone dying, you need to adjust the growth power value, namely multiplying it by 100/growing power will produce a planting point that is added to the embroidery seed.
Because sometimes the number of seeds per hole is more than 1 seed, the number of planting points needs to be multiplied by the number of seeds per planting hole.
The results are to determine the total population number including embroidery. Because the unit is grams, it is necessary to convert the total population number to grams by multiplying the total population by the weight of 1000 seeds/1000.
So that’s about How to Calculate Seed Needs Correctly. Hopefully it can be useful and can be applied.
