“…Furthermore, these relationships indicated that number of tillers per unit area is the main determinant of grain yield in response to seed rate. Previous studies have reported similar relationships between yield and related attributes (Spink et al, 2000;Lloveras et al, 2004;Guberac et al, 2005;Lithourgidis et al, 2006;Ozturk et al, 2006).…”

W heat (Triticum aestivum L.) is the major staple food cereal crop in most of the countries and cultivated in wide range of environments. Its yield is greatly influenced by crop management factors. Among several crop management factors sowing method, seeding rate and selection of appropriate genotype have prime role in affecting wheat productivity (Chauhdary et al., 2016;Isidro-Sánchez et al., 2017). Appropriate sowing method not only aids in establishment of proper crop stand but also improves the conversion of light energy by balancing inter-plant competition thereby improving the crop yield (Ali et al., 2012;Ehsanullah et al., 2017;Rasool et al., 2017). Hence such cultivation system and/or sowing method should be adopted which could improve the soil properties such as moisture, temperature and root penetration in order to improve the plant growth and productivity (Krause et al., 2009). Ridge sowing of wheat improves the crop yield and water saving by improving the plant tillering capacity, soil moisture content and nutrient availability (Hussain et al., 2018). However, ridge sowing often Abstract | Wheat productivity could be improved by ridge sowing with optimized seed rate for different varieties. This 3-years study was conducted to determine the optimum seed rate for different varieties of ridge sown wheat for better yield and related components. Wheat varieties (Faisalabad-08, Punjab-11 and Galaxy-13) were sown on ridges using two different seed rates (125 and 150 kg ha -1 ). Increase in seed rate improved the emergence (plants per m 2 ), number of productive tillers per m 2 and grain yield (3-7%) of all wheat varieties although productive tillers per plant, number of grains per spike and 1000-grain weight was decreased. Faislabad-08 performed better regarding grain yield and related components among all varieties. Seed rate and varieties did not interact significantly for studied traits. Correlation analysis revealed that grain yield was positively correlated with number of productive tillers per m 2 during all years and grain weight during first year; while, negatively correlated with number of grains per spike during second year indicating that increase in grain yield was associated mainly with increase in number of productive tillers per unit area in response to seed rate. In conclusion, increase in seed rate improved the grain yield of ridge sown wheat by enhancing the number of productive tillers per unit area and could be exploited to improve the wheat productivity.

“…Also, the highest kernel yield was achieved with sowing rate 600 germinable seeds m -2 (Kristó et al, 2007;Maric et al, 2008). On the other hand, various sowing rates had highly significant influence on the number of fertile tillers (Khaliq et al, 1999;Chaudhry and Hussain, 2001;Wajid et al, 2004), and that sowing rate influences mainly of number of spikes per square meter, which has the closest relationship to yield from all yield components (Spink et al, 2000;Guberac et al, 2000;Lloveras et al, 2004;Stougaard and Xue, 2004;Guberac et al, 2005;Lithourgidis et al, 2006;Ozturk et al, 2006).…”

“…Numerous studies have documented how N fertilization (Campillo et al, 2010;Hirzel et al, 2010;Zecevic et al, 2010;Nikolic et al, 2012), seeding rate, planting date, row spacing, and seeding depth affect yield and yield components of wheat (Wajid et al, 2004;Guberac et al, 2005;Schillinger, 2005;Kristó et al, 2007;Maric et al, 2008;Otteson et al, 2008;Valério et al, 2009). Seeding rates for winter wheat can vary widely due to differences in seed quality, planting conditions, planting dates and planting equipment (Lloveras et al, 2004).…”

Planting density is important factor which influence yield and quality of wheat (Triticum aestivum L.) For this reason, in scientific investigations is constantly investigated optimization of plant number per unit area. The objective of this study was to determine the influence of seeding rate in grain quality of winter wheat cultivars. The experiment was conducted with four winter wheat genotypes ('Ana Morava', 'Vizija', 'L-3027', and 'Perla') at the Small Grains Research Centre of Kragujevac, Serbia, in 3 yr at two seeding rates (SR1 = 500 and SR2 = 650 germinating seeds m -2 ). The 1000-kernel weight, Zeleny sedimentation, and wet gluten content in divergent wheat genotypes were investigated depending on the seeding rate and ecological factors. Significant differences in quality components were established between investigated seeding rates. The highest values of all investigated quality traits were established in SR2 variant when applied 650 seeds m -2 . Genotypes reacted differently to seeding rate. 'Perla' in average had the highest mean sedimentation value (42.2 mL) and wet gluten content (33.76%) in SR2 variant and this cultivar responded the best to seeding rate. Significant differences for sedimentation value and wet gluten content were found among cultivars, years, seeding rate, and for all their interactions. Also, ANOVA for 1000-kernel weight showed highly significant differences among investigated varieties, seeding rate and growing seasons, but all their interactions were not significant. In all investigated genotypes, better quality was established in SR2 variant when applied 650 seeds m -2 .

In South Asia, including Bangladesh, most farmers sow wheat under residual soil moisture after rice is harvested, but the upper layer of soil dries quickly after soil has been prepared for wheat sowing. Crop seeds that are sown either deeply or shallowly can result in failed emergence, low dry matter accumulation, and reduced grain yield. Therefore, appropriate sowing depth is crucial for seedling emergence and successful crop establishment. Considering this, a two-year field experiment was conducted at the research field of the Agricultural Research Station of the Bangladesh Agricultural Research Institute at Dinajpur during the dry, rabi (winter) season of 2013-14 and 2014-15, at four sowing depths, i.e., 2, 4, 6 and 8 cm, to identify the most appropriate sowing depth for higher grain yield. Wheat seeds sown at a depth of 4 cm resulted in significantly highest number of seedlings and seminal roots, tallest plants as well as largest roots and plant biomass followed by sowing at a depth of 6, or 2 cm. Depth of sowing also significantly affected the yield and yield-related attributes, all performing best at a depth of 4 cm. The highest number of spikes m-2, grain yield, straw yield and harvest index were observed when seeds were sown at depths of 4 or 6 cm, relative to 2 or 8 cm. Therefore, a sowing depth of 4 to 6 cm is recommended for wheat cultivation in South Asia, including Northern Bangladesh.
