"useSa": true The magnitude of yield loss observed over 8 site-years ranged from 1.2 to 4.5 bpa per inch of SD. The experiment was conducted by Augmented Experimental Design consisting of, Oilseeds are of great value in nutritional demands of mankind, animal feeding, and medicine. "useRatesEcommerce": false, That level of plant population is called as optimum population 9. 2019. 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]. 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).

Lemmon, H.E. Effects of plant population and row spacing on yield and ALDRICH, R. J. Staking was the most important factor in increasing total tuber production, which was one and a half times greater in staked than in unstaked plants and leaf-area development was closely and positively related to vine growth, and since staking and N application encouraged vine growth these treatments led to the production of plants with greater leaf area. Among them, safflower (Carthamus tinctorius L.) is an important annual industrial crop. 27 March 2009. interaction effects on grain yield were significantly higher under the highest PPD (148,148. plants/ha) and 20, 40 and .

Two-week-old rice plants were inoculated with different M. graminicola densities (250, 500 . Pucher, Michael A. Timmo) were aged they showed delayed field emergence and slower seedling growth. The experiment was a split. 2019. Winkler, Johanna Several management practices are implemented to mitigate yield losses caused by SCN, including using SDHI (succinate dehydrogenase inhibitors) fungicides delivered as seed treatments. 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. Field trials were therefore conducted to study the effects of four plant densities, varying from 2.0 to 12.5 plants m-2 on water and radiation use and performance of two Masakwa .

Meloidogyne graminicola is a destructive soil-borne pathogen that causes rice yield losses (Oryza sativa L.) in tropical and subtropical areas. Earthworms mix soil layers and bind the soil with organic matter. 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. Periodical Article for Undergraduate. Soybean (Glycine max (L.) Merr.) . However, This combination allows organic matter to disperse through the soil and also allows plants to access the nutrients they retains and enhance the soil's fertility. and Productivity in relation to interception of solar radiation, Vegetative growth of corn as affected by population density (2). The effect of H. zea feeding on soybean final yield is a complex process (Reisig et al.
