Previous studies documented that row spacing reduction did not modify maize canopy size (i.e. leaf area index); but increased maximum fIPAR and grain yield at low plant densities (~40-65.000 plants/ha) [ 15, 16 ] or at high plant densities (>75.000 plants/ha) but with low soil resources that affected canopy size [ 9, 1 A 30-day (approx.) window exists where corn can achieve 95% or more of maximum yield potential. Once the planting date is about two weeks beyond the ideal date (as shown here as May 15th) the amount of potential yield loss per day begins to increase. The graph in figure 1 assumes that all other factors throughout the year are equal Adopt a spacing of 60X25 cm. This means that distance should be 25 cm between plants in the rows that are 60 cm apart. For hybrids 6-7 plants / sq. m. 8 - 9 plants / sq. m. is considered good for baby corns Selecting row spacing and plant density At Buffelsvallei, planting maize at narrower spacing (0,52 m) in both tillage systems gave comparable yields regardless of planting density (Graph 3a). However, when rows are spaced at 0,76 m, yields from conventionally tilled plots were superior to minimal soil disturbance across all plant densities
Overall, these results suggested that by selecting the appropriate strip width (SW3; 0.40 m for soybean row spacing, 0.40 m maize row spacing, and 0.60 m spacing between soybean and maize rows), we can increase the nutrient uptake (especially nitrogen, phosphorus, and potassium), dry‐matter accumulation, and seed yields of relay‐intercrop species under relay intercropping systems Thus, to achieve potential economic yield of BH-546 variety modification of plant spacing with appropriate N-fertilizer rate should be determined. Keeping this in mind this study was designed with the objective of determining the optimum intra-row spacing and N- fertilizer level for BH-546 maize variety at Bako agro ecological conditions maize was 0.50 m with a total strip width of 1.80 m; SW3, row spacing for soybean and maize rows was 0.40 m, dis-tance between the rows of soybean and maize was 0.60 m with a total strip width of 2.0 m; SW4, row spacing for soybean and maize rows was 0.40 m, distance between th optimum plant population of 53,333 plants/ha for maximum yield of maize. Their report indicated that this is obtainable using a spacing of 75cm x 25cm at 1 plant per stand or 75cm x 50cm at 2 plants per stand. Azam et al., (2007) reported that spacing of 75cm x 35cm resulted in increased grain yield of maize while 75cm

Ukraine showed that the optimum densities ranged from 40-50 thousand plants/ha for late-maturing hybrids to 60-70 thousand plants for medium-early hybrids grown for grain-A.V.B Keywords: maize, grain yield, plant density, row spacing Introduction According to Pepó and Sárvári (2013), maize is a plant with individual productivity; therefore plant density determines yield significantly. Optimal plant density can be affected by the genetic properties and vegetation time of the given hybrid, just as by the conditions. There is little information on the optimum spacing intervals of improved white maize for optimum growth and yield in Nigeria. Field experiment was conducted at the students' practical farm, of the Department of Agriculture Technology, Federal Polytechnic Mubi in during the 2013 cropping season, to assess the effects of different spacing.

The study was conducted 2017-2018 under supplementary irrigation at Gulliso district, Western Ethiopia, to determining the effects of variety and intra-row spacing on yield of maize (<i. The optimum row spacing of maize cultivars varies with environmental factors, such as soil fertility, moisture supply, genotype, planting pattern, plant population and harvest time (Gonzelo et al. 2006). The architecture of maize has been changed to favor plants with more erect leaves (Duvick, 1984). Currently grow
Row spacing - corn. Row widths continue to decrease as time moves forward. Current row widths employed by producers typically vary from 15 to 38, with most producers at 30 today. Yet more and more acres are planted to narrower row widths. In general, this means 15 or 20 row widths Spacing: 60×25cm or 75×20cm But crop geometry of 45×20cm is found to be optimum for most of the areas. Method of sowing: Dibble the seed 2-3cm deep & should not be more than 5cm. Weed Management: Maize needs two inter-cultivations & two hand-weeding's. First inter-cultivation is done between rows near to plants for earthing up
Planting: To achieve the optimal planting density of 22 plants per square meter, farmers should sow one seed per hole at an inter-row spacing of 30 cm and intra-row spacing of 15 cm. The first weeding should be done between 20 and 50 days after planting, depending on the local weed growth intensity Optimum Corn Planting Depth - Don't Plant Your Corn Too Shallow Gregory A.

November 8, 2017. Maize is the most important cereal crop in sub-Saharan Africa. It is a staple food for an estimated 50% of the population. It is an important source of carbohydrate, protein, iron, vitamin B and minerals. Africans consume maize in a wide variety of ways (porridges, pastes and beer) Spacing There is need to observe optimal plant population in the entire farm, meaning the required spacing is 37cm by 35cm. Alternatively 75cm by 25cm is equally good
by population density, as increased plant densities have resulted in reduced maize forage quality, (Cox & Cherney, 2001). Optimal plant densities for maize forage production vary widely from 45,000 to 125,000 plants ha-1, depending on growing region (Baron et al., 2006). Among of new produced hybrids can be named SC703 and SC704 The crop is sown in the month of mid-October - November. Spacing. To obtained higher yield along with resource-use efficiency, optimum plant spacing is the key factor. 1) For winter and spring maize : Use spacing of 60x20 cm. 2) Sweet corn : Use 60x20 cm spacing. 3) Baby corn: Use 60x20 cm or 60x15 cm spacing In the highland and medium areas where the soils are well-drained sandy-loam soils, planting depth of 2 to 3 cm is optimal, as deep seed placement retards germination and emergence of maize seedlings. In dry and coastal low land areas where the soil is dry and/or sandy, maize seed should be planted more deeply (5 to 10 cm) One line of maize on each raised bed is desirable when sole crop of maize is planted keeping seed to seed spacing at 20 cm. Optimum plant density (30,000/acre) should be maintained to tap full potentials of hybrids. Southern side planting is advised on East-West oriented ridges . Keeping this in mind this study was designed with the objective of determining the optimum intra-row spacing and N- fertilizer level for BH-546 maize variety at Bako agro ecological conditions.

This necessitated the integration of optimum row spacing by plant density to maintain productivity and sustainability the yields Expan
Sowing methods and spacing vary, and fertility and water are decisive factors in choosing the optimum density in relation to light interception and highest yields. Plant population varies from 20000 to 30000 plants per ha for the large late varieties to 50000 to 80000 for small early varieties. Spacing between rows varies between 0.6 and 1 m The treatments included: (i) the control, conventional flat planting without plastic film mulch (CK); (ii) flat planting with maize rows (60 cm spacing) on plastic film mulch (70 cm wide); (iii) furrow planting of maize (60 cm spacing), separated by consecutive plastic film-mulched ridges (each 50 cm wide and 15 cm tall); (iv) furrow planting. Crop management practices to increase maize yield. Maintenance of an optimum soil pH ensures nutrients are readily available and maximizes growth. The preferred pH is in the range of 6 - 7.2 (Measured in water). maize has poor tolerance of low (<5.0) pH soils when aluminum toxicity reduces root development and manganese toxicity reduces plant.
Background: Maize fodder is being used as staple feed for livestock but it lacks protein and essential amino acids; lysine and tryptophan. Intercropping maize with leguminous soybean crop is promising technique under limited land resources of South Korea but it can only give considerable advantages when adequate distance is provided between corn and soybean rows Determination of optimum plant population and the use of improved varieties in combination with appropriate agronomic practices are important components of maize production package for maximizing productivity.

response of hybrid maize to plant density and fertilizer requirement varies widely. Summarizing the review undertaken, it can be concluded that the potential productivity of hybrid maize could be achieved when it is grown under optimum spacing of 75 x 20 cm and high fertilizer levels of 200:100:100 NPK Kg ha-1 under irrigated condition * To convert measurements to a per hectare basis, multiply by 2.471. Draw a line across all the planter rows (e.g. for a six row planter, place a line across six rows). Measure the amount of distance to give 1/1,000 th of an acre (Table 1) and draw another parallel line across the same six rows.; Count the number of plants between the two lines for each of the rows Maize is an expensive crop to grow, costing around £300/acre, so getting it right and achieving good yields are important. Below, Maize Growers Agronomist Simon Draper and consultant Ian. Timely planting of full-season hybrids allows the corn crop to take full advantage of the available growing season. Numerous studies have shown that corn yield potential declines as planting is delayed beyond the optimum planting window for a given geography (Coulter, 2012; Farnham, 2001; Myers and Wiebold, 2013; Nafziger, 2008) THE optimum plant density for a crop often decreases as the climate becomes drier. The usual explanation for this, that wider spacing of plants decreases competition for water1,2, overlooks the.

Maize farmers in Kenya are required to ensure that their soils are well structured if they are to gain optimum yields. Every year many maize farmers suffer getting losses due to one problem or the other. The Vertical Tillage concept, (recommended cultivation method) provides a system-based approach that focuses. biofuel usage. This requires matching of the best maize hybrids with optimal plant population and spacing. Modern maize hybrids have increased crowding stress tolerance, and Bt (Bacillus thuringiensis) hybrids now resist European corn borer and corn rootwor pattern (i.e. 40 cm narrow-row spacing and 160 cm wide-row spacing of maize) during 2012 and 2013, respectively. Combined with actual yield loss and LER, the intense intra-specific competition of maize plants reduced the depression for the associated soybeans when the maize narrow-row spacing was less than 30 cm The magnitude of yield loss observed over 8 site-years ranged from 1.2 to 4.5 bpa per inch of SD. Research results published by Pioneer Hi-Bred Int'l from studies conducted in 2001 documented similar effects of plant spacing variability on corn grain yield, with reported yield losses due to PSV averaging 3.4 bpa per inch of SD ( Doerge et al.
In SII, 40:160 optimum strip width for growing maize and soybean, it is the best planting pattern to minimize the shading effect of maize on soybean at critical stages during the co-growth period. Although maize can tolerate high temperatures up to 35 °C, yields usually decrease if the high temperature coincides with pollen shedding. Maize responds diferently to changes in temperature at diferent stages of growth. During germination, the optimal temperature appears to be around 18 °C. Germination is low at temperatures belo . Adequate agricultural inputs, particularly nutrient amendments and best management practices, are essential to reverse this trend. There is a need to understand the cause of variations in maize yield, provide reliable early estimates of yields, and make necessary recommendations for.
Maize density is calculated based on row spacing, row length, number of plants per planting station, and the distance between two consecutive planting stations. Gaile reported the dry moisture content of maize (min 25%, optimum 28-30%) as the main criterion for determination of proper harvesting time 52,000 cobs of maize could be harvested on one hectare of land, and the average price at the farm gate per cob is N10. The minimum amount realizable from a well cultivated hectare of land is N520,000
With regard to crop geometry, significantly higher grain yield was obtained at a spacing of 30/90 × 20 cm, whereas higher stover yield was obtained at a spacing of 60 × 15 cm. The highest B:C ratio was obtained at IW:CPE ratio of 1.0 with a spacing of 30/90 × 20 cm. KEY WORDS: Crop geometry, Irrigation, Rabi maize, INTRODUCTIO Late season maize is recommended only for areas where rainfall is likely to be adequate. Popcorn is best planted in the late season where proper drying could be easily effected for optimum popping expansion. Planting should be done preferably between 1-15 August.

When maize is planted prior to or later than this optimum window, a yield decline can be observed (Zhou et al., 2016). The optimum timeframe for maize establishment usually refer The optimum plant density for getting higher yields in maize crop is 66,667 pl/ha with a spacing of 75X20 cm and is on par with a spacing of 60X20cm i.e.,83,333pl/ha. Among the fertilizer levels, the grain yield of maize recorded higher at 150% RDN but was found to be on par with 100 or 200% RDN hence farmers can go with recommended dose of. They are planted in ridges, rows or furrows but for optimum growth, it is recommended that ridge spacing must be 2 to 4 inches apart to avoid choking up the germinating seeds. It is also recommended to plant maize seeds twice or thrice in one season to ensure continued harvest

Plant spacing, on the other hand, refers to the ARRANGEMENT of plants on the area planted. Example: Widely varying plant spacings such as 1 000 mm x 10 mm, 500 mm x 20 mm and 100 mm x 100 mm, all give a plant population of 100 plants per square metre. Question: What is the optimum population or spacing for a specific vegetable crop The maize plant produces high drymatter yields and therefore has a high requirement for nutrients especially nitrogen (N), phosphorus (P) and potassium (K). It is not usually necessary to apply fertiliser to supply all the crops nutrient requirements. Crops planted in paddocks that have recently been in pasture can usually extract a significant.
Maize is highly responsive to nitrogen fertilizer rates and plant spacing. Continuous efforts have been carried out to improve the yield potential of maize by modifying their architecture through breeding methods with aim of increasing maize yield through increasing number of plants ha-1. Hybrid BH-546 is the recently released variety for this purpose but its optimum nitrogen rate and spacing. An array of production technologies, from land preparation to harvesting, has been recommended for maize crop. Being non-tillering crop, optimum plant population can be achieved if suitable crop establishment techniques like method of sowing, sowing time, seed rate, seed treatment, crop geometry etc., are followed. Weeds can be managed well either by two hoeings 15-30 days after sowing or. In that study narrow-row spacing of maize ranged from 80 to 20 cm under relay strip intercropping, the yield of intercropped maize decreased by 25.53-3.13% . Maize growth could be highly sensitive to spatial arrangement and interplant competition might affect growth of neighboring plants negatively . Although comparative data between 5 cm and. The increase of maize populational density resulted in increases of plant and first ear heights and in decrease of the number of grains per ear. The best planting arrangement for both hybrids was 0.40 m row spacing and 75,000 and 80,000 plants per hectare
The cost of experiments aimed at determining linkage between marker loci and quantitative trait loci (QTL) was investigated as a function of marker spacing and number of individuals scored. It was found that for a variety of experimental designs, fairly wide marker spacings (ca. 50 cM) are optimum or close to optimum for initial studies of marker-QTL linkage, in the sense of minimizing overall.

. Introduction Maize (Zea mays L) is one of the most versatile emerging crops having wider adaptability under varied agro-climatic conditions. Globally, maize is known as queen of cereals because it has the highest genetic yield potential among the cereals. It is cultivated on nearly 150 m ha in about 16 Field trials were carried out in the Sudan Savannah of Nigeria to assess the usefulness of CERES-maize crop model as a decision support tool for optimizing maize production through manipulation of plant dates. The calibration experiments comprised of 20 maize varieties planted during the dry and rainy seasons of 2014 and 2015 at Bayero University Kano and Audu Bako College of Agriculture. The study was conducted in 2017 main cropping season at two locations in North Gondar Zone, Ethiopia, to determine the optimum inter- and intra-row spacing of mung bean for maximum yield and yield components. The experiment was laid in a randomized complete block design with three replications in a factorial arrangement of four inter-row (20, 30, 40 and 50 cm) and three intra-row (5, 10 and 15. Transplant 2 - 3 seedlings per hill at shallow depth at optimum spacing (20 cm x 20 cm or 22.5 cm x 22.5 cm). Handle seedlings carefully to ensure their fast revival and rapid growth after transplanting. Limitations: Transplanting is tedious and time-consuming (up to 30 person-days ha-1). Planting laborers can suffer from back problems. The Agricultural Production Systems Simulator (APSIM) model was calibrated and validated and used to identify the optimum planting windows for two contrasting maize varieties for three agro-ecologies in the Nigeria savannas. The model was run for 11 planting windows starting from June 1 and repeated every 7 days until 16 August using long-term historical weather data from the 7 selected sites.
