Generally speaking, for 36-inch rows, growers should be planting a minimum seeding rate of around 36,300 seed/A (2.5 seed/foot of row, or 2 seed every 9.6 inches hilldropped) in order to expect a final plant population of 30,000 plants/A. The Corn Population Chart provides a quick guide on how corn population varies by row width and average seed spacing. Trop. The study of plant population frequency using quadrat is a post-planting operation. Plant population can be determined using several methods. For maize, 75cm by 25cm is used if one seed is to be planted per hole, 75cm by 50cm is used if two seeds are to be planted per hole and lastly, 75cm by 75cm is used if 3 seeds are to be planted per hole. Alofe et al. The closer the spacing, the more plants there will be per unit area. Then you can estimate the cost of seeds and planting material yourself. Results showed that there was a significant difference between the estimate by physical counting and estimation by the existing mathematical formula. To determine on a jerib basis just divide the above number by five. The Plant population of any field is given by multiplying the between plants spacing with the spacing between the rows. of plants/m². Place a 30cm stick/ruler or clipboard along a row. The formula is flexible and can be used for direct estimation of plant population in any given four dimensional fields of sole crop. Take that number and multiply by 100 then divide by the seed row spacing in cm to get plants per square metre. Learn the formula. Monocropping, simple and complex mixing in a cassava-based rotation system. You can use square feet or meters if you are finding the density of a smallish space. On Corchorus olitorius L., Tayo (1990) reported populations of 250, 000; 500, 000 and 1.0 million per ha for plantings done at 20x20, 20x10 and 10x10 cm, respectively. Most farmers find it easier and more reliable to count number of seeds per foot of row or seeds per acre instead of pounds or bushels per acre. cabbage) or 100 plants per square metre (e.g. In this consideration, L', B', l' , b' may be expressed as a parametric function of another variable. Agronomists have long known that evenly spaced stands of plants resulting in optimum plant population, have a greater yield potential than unevenly spaced stand (Carlson et al., 2003). When trying to calculate the amount of potato seed needed, the row spacing, within-row spacing, and seed size need to be taken into consideration. The recommended number of maize plants per hectare varies from 36,000 to 60,000, depending on the environmental yield potential and hybrid. The plant population definition is similar to the human population. For planting part of an acre or hectare the value has to be entered in decimal format. Suppose we want to have 55.000 plants per hectare and our row width is 90cm. Using plant population calculator is the easiest method. 1. that 32, 15.5, 6.1 and 6.1% of the snake tomato, tomato, amaranth and cock’s To figure planting rate, use this formula: You need to plant 7.9 seeds per foot of row to get six plants per foot. A quadrat, usually a square-shaped material with equal dimension and made of wooden material, is placed on certain portions of the farm at random. Maize planting population per hectare (10,000m) with a seed rate of one per hole, using the plant population formula, is approximately 53,333 plants. Onion Newslett. The optimization analysis of the farm field was also considered. carrot) Plant spacing, on the other hand, refers to the ARRANGEMENTof plants on the area planted. The experimental design was a randomized complete block. Crop Sci. In addition, I would indicate the plant population of the crops per hectare using the specified spacing. Such data are a land area, planting distance or spacing, and seed rate. The unit of land area should be square miles or square kilometers. Work out the area counted, eg: 30cm x drill coulter width. While tomato plant population per hectare (10,000m) using a spacing of 60cm by 60cm with two seeds per hole is approximately 55,556 plants.
