plant harvesting (Paroissien and Flynn, 1998) etc. Effect of N and stand density on grain yield performance of maize in a southwest location. Try it yourself to see how simple and easy it is. (1996) reported that cultivar ICPL 87091 pigeon pea (Cajanus cajan L.) required plant spacing of 60x20 cm (8.3 plants/m2 = 83,000 plants/ha) while cultivar KAT60/8 required 60x30 cm (5.5 plants/m2 = 55,000 plants/ha) for maximum grain yield. therefore was to develop a modified mathematical formula that could be used This is quite correct because what you weren’t taught is obviously going to be unknown to you. 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. Mariga and O.A. Once all these are provided, the device automatically provides the number of plants that will accommodate the provided land area. 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. In addition, I would indicate the plant population of the crops per hectare using the specified spacing. Distance Between Centers in Inches. Seeding Rate, Plant Rate Any successful planting begins with identifying the purpose of the planting; selecting suitable species that meet the desired objectives of the resource concern; to ensure normal density of young shoot and a maximum yield, you need to determine the number of seeds planted per hectare (ha) or acre, and how much seed needs to be purchased. Definitions, Formulas & Examples. 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. But these three methods are commonly used. Plant populations are not the same as seeding rates. formula. These parameters must be accurate to get accurate answers. How to calculate Number of Plant per Hectare. to determine with accuracy the plant population in a four dimensional field This page will assist you in selecting products and Distance Between Centers in Inches. Your crops need adequate space to garner all needed to facilitate their growth, such as nutrient, air, and water. Sci., 24: 4-9. https://scialert.net/abstract/?doi=ja.2006.289.292, Plant population determined by physical counting and mathematical The average of the result gotten 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. To calculate the population density, you will divide the population by the size of the area. Calculus One and Several Variables with Analytic Geometry. The use of plant population formula is the most effective and cheapest method. 2. (2003) proposed a formula, which is a variation of (1) using the Excel spreadsheet. planted at 75x5 cm to be 26, 700 plants per ha at one plant per stand while that of cassava planted at 1.0x1.0 m was 10,000 plants per ha at one plant per stand. 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. It is the manual method of the plant population calculator. Our online plant calculator can work out how many plants you need based on the measurements you provide, making your next landscaping project go smoothly! Lastly, you need to know the number of seeds you intend to plant per hole; this is called Seed rate. Population density, persons per hectare in England Select component type Select component type Select component type Select component type Select component type LG Inform. […] Firstly, you need to determine the population of plants on your farm; for this example, the population of maize on an area of 350sqm is 233 maize plants. ), amaranth (Amaranthus cruentus L.), cock`s comb (Celosia argentea L.) and snake tomato (Trichosanthes cucumerina L.). The recommended number of maize plants per hectare varies from 36,000 to 60,000, depending on the environmental yield potential and hybrid. Each crop was established on a 5x10 m plot, replicated three times and sowing was done at one plant per stand. for. A preliminary investigation of onion cultivation in a southwest location in Nigeria. Pp for non-regular field: We may propose plant population formula for a non-regular field, whose sides can be represented as a function of a variable. It is known that estimates of crop yield, crop performance, diseases and pests rating, water-use-efficiency, crop response to stress etc are always based on plant population estimates, therefore, accurate plant population estimates will give true and reliable information about these parameters. The number of trees per hectare, according to the spacing between the lines in a plantation and the spacing of plants within a line, is given in Table 4.1. Spacing is very important in crop production; spacing is the optimum feeding area or the most convenient area required by a particular plant to thrive well. The formula is flexible and can be used for direct estimation of plant population in any given four dimensional fields of sole crop. 5. 4. Isei, 1996. Plant Calculator. Vineyard Planting Density. Width in Feet. Calculate the seed rate of green gram for sowing 1 hectare of crop from the following: spacing=45cm×10cm germination %=80% 1000 grain weight =48g Solution: Plant population= 10000 0.45×0.1 =222222.22 Seed rate= 222222.22×48×100 80×1000×1000 =13.33 kg (Ans). 10,000, the more plants there will be per unit area number by five 37-44.Carlson,,.
