Adam, Eveline <jats:p>The objective of the study was to determine the effect of plant population on the growth and yield of maize. ., Sahab Rahmanzade Studies on the . The study was conducted during th . It is suggested that potential exists to increase biomass productivity by expanding the seasonal interval of photosynthesis, and that in the case of double-cropping, expansion of leaf duration is not necessarily associated with reductions in leaf efficiency. 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. Has data issue: true Whisler, F.D. In this study, the maximum above-ground biomass of 72605 kg/ha, leaf fresh weight 9510 kg/ha, leaf dry weight 5392.7 kg/ha, and Essential oil yield of 23.39 kg/ha was attained due to a spacing combination of 40cm intra-row and 60cm inter-row spacing's. Two field trials were done to evaluate the effects of plant density on the growth, development and yield of safflower. Initial rapid tillering resulted in a maximum tiller density within 37 to 63 d after seeding (DAS). Smooth Cayenne pineapples were planted in November 1986 in the Eastern Cape, South Africa, at plant population densities (population) of 43 421, 56 666, 65 570 and 82 500 plants ha-1.Plots were fertilized with 600 or 900 kg ha-1 of nitrogen applied to the plant and ratoon crop. Productivity in relation to interception of solar radiation, Vegetative growth of corn as affected by population density (2). The proportion of dry matter accumulated in the pods and side branches decreased with increase in population, whereas the proportion accumulated in the main stem increased. The lower populations are used under dryland conditions when soil-water levels at planting are low and the higher populations are used under irrigation. For example: for a target population of 100 plants/m 2 and using seed of average weight (35 mg) and a laboratory germination test of 95 percent.

The effect of virus on population growth rate depended on virus species and wild C. pepo population. Main-stem and lateral pods, seed pod1, potential fruiting sites and lateral branch number were inversely proportional to plant density, and lateral pod production was more sensitive to population pressure than main-stem pod production. The experiment was conducted by Augmented Experimental Design consisting of, Oilseeds are of great value in nutritional demands of mankind, animal feeding, and medicine. Over the range of the densities studied grain yield was positively related to number of side branches but negatively related to dry-matter production, leaf area duration and percentage of light intercepted. 1.10 Objective.

Torabi Jaf, Azarakhash 2014 English. Published online by Cambridge University Press: Lambert, J.R. Journal of the American Society for Horticultural Science. The fields having 225,000 plants per hectare produced the highest paddy yield of 4.6 ton/ha that was about 41 percent higher than the field with 175,000 plants per hectare. Seed rate = 100 x 35/90 or 39 kg ha-1 (check the first table for likely establishment percent).. For a plot size of 10 m x eight rows (at 20 cm spacing), or 0.0016 ha . (2002) concluded that higher grain yield were observed with increasing plant densities. yield. Plant populations ranged from 122 to 458 plants m 2. Timmo) were aged they showed delayed field emergence and slower seedling growth. That level of plant population is called as optimum population 9. Lemmon, H.E. Semantic Scholar is a free, AI-powered research tool for scientific literature, based at the Allen Institute for AI. 1991. The experimental approach was to grow field corn at various population densities to permit variations in amount and manner of light interception, and the growth rate of the crop in terms of dry matter accumulated in both shoot and root tissues is interpreted in relation to light interception by the foliage assemblages.
