And as a result, they cannot determine the adequate number of plants, seeds, or planting materials to use on their farm. In this post, we will walk you through it. So determine the area you want your plants to occupy on the farmland, say 80-90% of the total farmland. Once this is achieved, it becomes easy to know the number of seeds or planting materials needed for the crop to be planted. The formula for population density is Dp= N/A where Dp is the population density N is the total population and A is the land area covered by the population. Some tomato seeds are planted just one per hole using nursery trays. Estimation of yield (before harvest) e.g maize: It only provides an approximate answer. HtTKO@W h Note that you must use the same units in the plant population density calculation formula. Therefore the Plant population of potatoes per ha is 37037. How to estimate plant populations per acre. The average of the result derived with respect to the dimension of the quadrat is recorded and equated to the total land size to get the actual plant population of the whole farm.
