Seed Population Calculator
The correct plant population is essential for maximising yield and quality in vegetable and salad crop production. Proper spacing ensures uniform root development, reduces competition for nutrients and water, and minimises disease risk. Overcrowding can lead to small, misshapen roots, while under-planting wastes valuable space and reduces overall yield. Factors such as soil type, irrigation availability, climate conditions, and varietal characteristics must also be considered when determining the optimal plant density.
By paying close attention to plant population and employing best practices, growers can improve crop yields, uniformity, marketability and overall crop profitability. Successful vegetable and salad crop production balances science and management, where careful planning and monitoring yield the best results. You can read more about how to get the correct plant population in our grower's guide here.
Stanhay precision drills can be specified to suit most planting densities and provide precision seed placement in both seed depth and in line spacing. This calculator will help determine the correct settings for your machine to achieve the required plant population.
Instructions
Use this calculator to work out the required seed spacing for your required seed rate and planting layout. Then refer to the spacing chart to select the correct gear for your seed discs.
Alternatively, you can calculate the population you can achieve knowing the spacing range achievable with your seed discs and machine layout.
Note
If working in a field system rather than a bed system enter your row width as the tractor wheel track and number of lines per bed as 1.
