The lower populations are used under dryland conditions when soil-water levels at planting are low and the higher populations are used under irrigation. 27 March 2009. 2017) and higher population levels, plants under different environmental stress conditions, or the soybean growth stage when H. zea infests the field could provide more insight on potential compensation mechanisms to H. zea reproductive tissue feeding. The study results revealed that the plant population has a direct relationship with the crop yield. However, In another study recorded non-significant effects of nitrogen levels of 60, 90, 120 kg/ha and plant population of 53000, 71000 and 95000 plants/ha on early and late maize varieties in summer season, whereas, their effects were significant in winter season. The experiment was a split. Two-week-old rice plants were inoculated with different M. graminicola densities (250, 500 . Academia.edu no longer supports Internet Explorer. Light seems to be the major factor controlling grain yield in this variety of soya bean, low light intensity under the plant leading to a reduction in the number of side branches, number of pods per plant and number of nodes with pods. The magnitude of yield loss observed over 8 site-years ranged from 1.2 to 4.5 bpa per inch of SD. Baker, D.N. The interaction between faba bean genotypes and plant population had significant effects on all studied characters except number of days to flowering. 6. Abiotic and biotic stress factors negatively influence the growth, yield, and nutritional value of economically important food and feed crops. Hodges, H.F. Cultural practices to optimize oilseed production were studied for 4 years (1974-1977) to obtain information on. Klug, Martin Neugschwandtner, Reinhard W. ADEKOLA O.F, ABDULRAHAMAN A.L. Good puddle field conditions are needed to create a favorable environment for normal growth of rice plants. The plant population range for confection-type sunflower hybrids ranges from 12,000 to 18,000 plants per acre. Crop growth rate increased with increasing leaf area, which in turn increased with increasing plant density. Lemmon, H.E. Hampton appears to have the potential for high seed yield under the prevailing local conditions. 3.1. 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. 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. Render date: 2022-11-04T02:21:12.256Z In this context, a field experiment was conducted to study the effect of herbicides on soil microflora, root nodulation, growth and yield of chickpea under rainfed condition during the rabi season of 2017-18 and 2018-19 at Zonal Research Station, Chianki, Palamau, (Birsa Agricultural University, Ranchi), Jharkhand (India). and User. ., Abdollah Hasanzade To determine the effect of different plant densities on the yield and growth of common bean.

Plant population plays an important role in quality sugar beet pro duction. Light seems to be the major factor controlling grain yield in this variety of soya bean, low light intensity under the plant leading to a reduction in the number of side branches, number of pods per plant and number of nodes with pods. and 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. Neugschwandtner, Reinhard W. The production of biodiesel from the cold pressed oil of safflower of Balci variety grown in Yozgat ecological condition has been carried out and the fuel properties of the biodiesel produced were compared with that of TS EN 14214. 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. Seed rate to be used for sowing can then be calculated using the following formula. and 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. 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 Columbian exchange, also known as the Columbian interchange, was the widespread transfer of plants, animals, precious metals, commodities, culture, human populations, technology, diseases, and ideas between the New World (the Americas) in the Western Hemisphere, and the Old World (Afro-Eurasia) in the Eastern Hemisphere, in the late 15th and following centuries. 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. Contributions of life-history transitions and life-history traits to population growth rates varied among populations and virus treatments. Therefore, it could be concluded that Artemisia annua could be planted at an optimum spacing of 40 x 60 cm in the Wondo genet area to attain maximum yield. 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.
