In the semi-arid and cold area with low soil moisture of northern Shanxi, the planting density of the kidney bean variety 'Yingguohong' is recommended to be 240 000-260 000 plant/ha. Summary In soya beans (var. Abstract. On the other hand, when the number of plants per unit area decreased, the yield also decreased. Four safflower (Carthamus tinctorius L.) cultivars were evaluated at five plant populations in experiments over 2 yr at three North Dakota locations and Cultivar effects were significant for all yield components. However, Mean D-leaf width decreased with increasing population. Neugschwandtner, Reinhard W. Burcky and Winner (1986) found that increasing plant population resulted in higher root yield and/or higher sucrose con tent. Field experiments were conducted to evaluate plant population and N-fertilizer effects on yield and yield components of maize (Zea mays L.).Three levels of plant populations (53000, 66000, and 800000 plants ha 1 corresponding to spacings of 75 25, 60 25, and 50 25 cm) and 4 doses of N (100, 140, 180, and 220 kg ha 1) were the treatment variables. . 2014 English. SUMMARY Initial rapid tillering resulted in a maximum tiller density within 37 to 63 d after seeding (DAS). Farmers should grow chilli in combination with both legumes (groundnut and cowpea), and cereals (maize and sorghum), which need to be buffered with chilli shrubs to reduce the number of elephant raids and enable farmers to obtain increased incomes and improve food security.

Ganganagar Lime - 1 satya dwivedi 2022, International Journal of Current Microbiology and Applied Sciences Adam, Eveline In the regression fitting model of planting density and yield, the highest yield was achieved at the planting density 240 000-260 000 plant/ha. The highest seed yields were obtained when all the above got maximized (Tessbo et al., 2004). A higher number of plants is related to a higher number of fruit clusters and a higher number of fruits and, thereby, higher yield [12, 13]. Until 1948, the USDA recommendation for pickling cucumber spacing was 6 to 7 feet between rows and 3 to 4 feet between plants in the row, for a planting density of 1,500 to 2,500 plants per acre. Effect of plant population on growth and yield of soya bean( Glycine max ) @article{Enyi1973EffectOP, title={Effect of plant population on growth and yield of soya bean( Glycine max )}, author={B. However, this population-virus interaction was not evident when examining individual components of fitness. Measurements were taken at seventy five days after planting . ., Amir Fayaz Moghaddam Grain yield per hectare decreased by 38, 51, and 72% respectively with the increases in plant population, but yield of total dry matter per hectare showed a significant increase with density. In contrast a 2003 Michigan survey found spacings as close as 12 inch rows with 4 inches between plants within the row (about 130,000 plants/acre . Robinson and Worker (1969) concluded that the population influence on yield is the same over a wide range of climates. ., Sahab Rahmanzade Effects of Plant Density, Interlighting, Light Intensity and Light Quality on Growth, Yield and Quality of Greenhouse Sweet Pepper" Optimizing Plant Density and Nitrogen Application to Manipulate Tiller Growth and Increase Grain Yield and Nitrogen-Use Efficiency in Winter Wheat Published online by Cambridge University Press: 3.1. Field experiments consisting nine spacing: three row to row (inter row: 43 cm, 50 cm and 60 cm) and three plant to plant (intra row: 10 cm, 15 cm and 20 cm) with plant population ranging from 8-23/m2, Two field trials were conducted in 2007 and 2008 to determine the appropriate sequence of planting and spatial arrangement for the maize-soybean intercropping system for optimum growth. Components of growth, net assimilation rate and leaf area index. An increase in plant density has no effect on the growth and yield of common beans. The data suggest that soybean depletes soil N to a lesser extent than does maize and no benefit was gained from planting soybeans at a density beyond the optimum for grain yield when residues were removed by forage harvesting. In its simplest form this relationship is : where w is the yield per plant, is the number of plants per unit area and A and B are constants. 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 . ., Abdollah Hasanzade The minimum plant population that maximized grain yield in a 76-cm row spacing was 94,000 plants ha 1 but was 109,000 plants ha 1 in a 51-cm row spacing (Table 5). Under high plant population individual plant yieldwill be low due to narrow spacing leading to competition between plants. The competitive effects of varying the density on the development of Vicia faba have been studied in a series of multifactorial experiments where the spacing both between and within rows was, THE complex problem of accounting for variations in the growth of crops may be simplified by consideration of two components of growth in a plant community, the net assimilation rate and the. Total loading time: 0.228 Grain yield per hectare decreased by 38, 51, and 72% respectively with the increases in plant population, but yield of total dry matter per hectare showed a significant increase with density. 588-591 ISSN: 0974-0112 Subject: Citrullus lanatus, fruit weight, fruits, grasses, horticulture, mulches, plant growth, soil temperature, soil water, vines, volumetric water content .
