Study of effects genetype and date of sowing on quantitative and qualitative traits in Canola (Brassica napus) in Bushehr provience
به منظور تعیین مناسب‌ترین رقم و تاریخ کاشت، شش رقم کلزای بهاره در استان بوشهر، از طرح کرت‌های نواری (Strip Plot) در پـایه بلوک‌های کامل تصادفی در چهار تکرار استفاده شد. آزمایش در سال زراعی 1377-1376 در برازجان مورد بررسی و ارزیابی قرار گرفت. هر واحد آزمایشی شامل چهار خط سه متری با فواصل بین ردیف 50 سانتی‌متر و بین بوته 10 سانتی‌متر بود.ستون عمودی شامل شش رقم به اسامی: 1-گلوبال (Global)، 2-ر...
متن کاملUsing simulation models to investigate the cumulative effects of sowing rate, sowing date and cultivar choice on weed competition
With the increasing pressure on crop production from the evolution of herbicide resistance, farmers are increasingly adopting Integrated Weed Management (IWM) strategies to augment their weed control. These include measures to increase the competitiveness of the crop canopy such as increased sowing rate and the use of more competitive cultivars. While there are data on the relative impact of th...
متن کاملResponse of Spring Wheat (Triticum aestivum L.) Quality Traits and Yield to Sowing Date
The unpredictability and large fluctuation of the climatic conditions in rainfed regions do affect spring wheat yield and grain quality. These variations offer the opportunity for the production of better quality wheat. The effect of variable years, locations and sowing managements on wheat grain yield and quality was studied through field experiments using three genotypes, three locations for ...

متن کاملSpring wheat leaf appearance and temperature: extending the paradigm?
Extensive research shows temperature to be the primary environmental factor controlling the phyllochron, or rate of leaf appearance, of wheat (Triticum aestivum L.). Experimental results suggest that soil temperature at crown depth, rather than air temperature above the canopy, would better predict wheat leaf appearance rates. To test this hypothesis, leaf appearance in spring wheat ('Nordic') ...
