J., 9: 487-497.Direct LinkObuo, J.E., F.H. 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. of the physically counted plants with the estimate by mathematical formula showed 1 are not correct because significant number of plants on the plot are not taken into consideration. (2001) and Rubaihayo et al. 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. 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. Effect of N and stand density on grain yield performance of maize in a southwest location. You can use square feet or meters if you are finding the density of a smallish space. CALCULATE PLANT POPULATION PER HECTARE OR JERIB (1 Ha = 10,000m² and 1 Jerib = 2000 m²) Multiply linear meters per Ha at a 0.42 meter row width by number of plants/meter. Repeat in 10 representative areas of the field/1 count per hectare and calculate the average. of plants/m². Such data are a land area, planting distance or spacing, and seed rate. Draw a line across all the planter rows (e.g. For planting part of an acre or hectare the value has to be entered in decimal format. It makes use of the same data as other methods. Plants Needed: Based on # Sq. In a study on cowpea (Vigna unguiculata (L.) Walp. Mathematical Handbook of Formulas and Tables, Schaums Outline Series. Square Planting Pattern. Use our handy calculator to determine the appropriate number of plants needed for an area. Work out the area counted, eg: 30cm x drill coulter width. of this formula is inaccurate because significant number of plants is not accounted (2001) resulted in 24000 plants/ha at 90x45 cm and 37000 plants/ha at 90x30 cm at one plant per stand. Agric., 18: 37-44.Carlson, C.G., T.A. The planting spacings used were 50x50 cm, 20x20 cm, 20x20 cm and 1.0x1.0 m for tomato, amaranth, cock’s comb and snake tomato, respectively. Using just the right amount of pesticide and fertilizer minimizes the potential for personal, property, or environmental damage and maximizes consumers’ return on the dollar. Length in Feet. 5 becomes. Notify me of follow-up comments by email. (2002) among several others have established that the plant population plays a significant role in the final crop yield under any given condition. Your crops need adequate space to garner all needed to facilitate their growth, such as nutrient, air, and water. (1987) estimated the population of soybean (Glycine max Merill.) You can use square feet or meters if you are finding the density of a smallish space. 3. Ecological adaptation of some improved IITA soybean varieties in a humid forest ecosystem. cabbage) or 100 plants per square metre (e.g. Then you can estimate the cost of seeds and planting material yourself. Taking derivatives of (7), we have, The critical points (lc, bc) are obtained when. On-farm experience has shown that the values obtained by the above formula First convert cm to m 45cm =0.45m, 5 cm =0.05 2. Since the plant population (Pp) is varying with respect to the dimension of the spacing l and b, we can minimize (or maximize) Pp subject to a constraint on the plant spacing. The recommended number of maize plants per hectare varies from 36,000 to 60,000, depending on the environmental yield potential and hybrid. Field studies were conducted at the Teaching and Research Farm, Obafemi Awolowo University, Ile-Ife, Nigeria, to compare the plant population estimates by physical counting and by using existing mathematical formula, on sole crop fields of tomato (Lycopersicon esculentum (L.) Mil. Lastly, you need to know the number of seeds you intend to plant per hole; this is called Seed rate. Plant population = 10 000 _____ between plants spacing (m)x between rows spacing row (m) An example If the between plant spacing of soybean is 5 cm and between row spacing is 45 cm what is the plant population per hectare? Ajadi Mariga and O.A. Annual Report of Resource and Crop Management System, International Institute of Tropical Agriculture Ibadan, Nigeria, pp: 138.Mutungamiri, A., I.K. 3. :) Notice that you can also use the plant spacing calculator to find the total rows and number of plants per row. How to calculate Number of Plant per Hectare. For example, with a spacing between lines of 3 meters and a spacing of plants within a line of 3 meters, a planting density of 1,111 trees per hectare … 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. 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. 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.In a study on cowpea (Vigna unguiculata (L.) Walp. The two values were thereafter compared to ascertain the reliability and accuracy of the mathematical formula. The first thing you must know is the area of your field. Effect of Spacing on Yield of Two Pigeonpea Cultivars in Uganda. 1). Population density, persons per hectare in England Select component type Select component type Select component type Select component type Select component type LG Inform. In: Improvement of Pigeonpea in Eastern and Southern Africa: Annual Research Planning, Silim, S.N. 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. The condition in Eq. Population density – Population density is the number of people per unit of area, usually hectare or square kilometer. However, some potatoes are planted at 34- and 38-inch row spacing. comb plants were not accounted for by the mathematical formula. The analysis of functions for Minima and Maxima is well documented by Spiegel (1968), Swokowski (1979) and Salas and Hille (1982). and A.B. Let L and B be the length and breadth of the farm, respectively, while l and b are the length and breadth of the spacing on the farm land and N the number of seeds per stand. SSMG, 37: 1-16.Dashiell, K., H.C. Ezumah and S.O. Isei, 1996. This constraint is subject to prevent overcrowding, thereby leading to an optimal yield. Each crop was established on a 5x10 m (50 m2) plot and sowing was done at one plant per stand. All the missing stands were supplied, leaving no room for vacancy. ), amaranth (Amaranthus cruentus L.), cock’s comb (Celosia argentea L.) and snake tomato (Trichosanthes cucumerina L.). Calculus One and Several Variables with Analytic Geometry. This therefore shows that the above formula does not estimate accurately Example: 23,805.5 linear meters/Ha x 3.7 plants/linear meter = 88,095 plants/Hectare. The plant spacing calculator will tell you how many plants you need in a rectangular and a triangular grid - here, 6,188 for a rectangular grid and 7,059 for triangular spacing. The plantain suckers were planted early June 2019 with a plant population of 1200 using a plant spacing of 3m by […]. Once all these are provided, the device automatically provides the number of plants that will accommodate the provided land area. In agronomic research, especially in the conduct of field studies to evaluate crop performance, the determination of optimum sowing spacing and plant population per hectare (ha) is crucial. meter (no. 5. where the unit of measurement of L, B, l and b must be uniform (centimeter (cm), meter (m), etc.). (1996), Mutungamiri et al. The term plant population refers to the number of soybean plants per acre. 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. Hence, (17) is a general form of Eq. Care was taken to ensure that the spacings were accurately measured out. To figure planting rate, use this formula: You need to plant 7.9 seeds per foot of row to get six plants per foot. J. Nig.
