We will approach the "Choosing the Right Number of Crops" topic in a slightly different way and the readers can choose the one which suits them best.
The different approaches are namely
- Keeping the Area Fixed and the Numbers in a single Crop Variable
- Keeping the Numbers in a single Crop Fixed and the Area Variable
- Keeping the Tonnage / Money in Sight while keeping others variable
Option 1: Keeping the Area Fixed and the Numbers in a single Crop Variable
In this option, we keep the Area Fixed and allow the numbers in a Crop (specifically for trees, plants) to be variable.
To make it easy for the readers, I am giving an example below:
Lets assume a 250 Sq Ft (250 X 1) fixed area.
In this, we can plant every 25 feet 1 Coconut Tree which comes to 10 or 11 Coconut Trees if we squeeze in 1 at the beginning and 1 at the last. If we go for Timber Trees, we can plant 1 Melia Dubia Tree every 6 feet which comes to 42 or 43.
Option 2: Keeping the Numbers in a single Crop Fixed and the Area Variable
In this option, we keep the Numbers in a Crop Fixed and the Area be allowed to vary based on the numbers.
Assuming we want to plant 25 Trees for every Crop. Lets see how this works out.
Taking the same example of Coconut and Melia Dubia, we arrive at the numbers below for the land requirement.
For Coconut Trees, we require 601 Sq Ft. For Melia Dubia, we require 145 Sq Ft.
Option 3: Keeping the Tonnage / Money in Sight while keeping others variable
In this option, we keep a set target in mind and we calculate back to get the results. This may look easy in paper while difficult to achieve in real terms. The reason being neither the yield nor the market rate is fixed and hence fluctuations may occur and if still want to go for this, use the historical data and use the averages to achieve it while factoring in a 10% (+/-) margin of error as a percentage to the base.
For example, we would like to achieve Rs.50,000/- or 1 Tonne every crop. So, we need to understand what is the yield of the crop and based on the yield we can calculate how many numbers in a crop are required. Here the area does not make sense at all for calculation.
To give an example, assuming 1 Mango Tree yield 100 Kgs per season, we may need to go for 10 Mango Trees for achieving 1 Tonnage.
The formula would be Number of Trees = Target Tonnage / Yield Per Tree
Using the same example for Target Money, assuming 1 Mango Tree yield 100 Kgs per season and keeping 100 Kgs @ Rs.2,000/- , we may need to go for 25 Mango Trees for achieving Rs.50,000/-.
The formula would be Number of Trees = Target Money / (Yield Per Tree X Rate)
