Effect of Fall and Spring Applied Nitrogen Fertilizer on Growth and Yield of Sugarbeets *
Received for Publication July 27, 1984 INTRODUCTION The time and amount of nitrogen (N) uptake affects both root and extractable sucrose yield of sugarbeets (Beta Vulgaris L.). Either excessive or late N fertilizer applications and subsequent plant N uptake from applied•or residual N sources cause an increasing proportion of the photosynthate to be used for top growth at the expense of both roo...
متن کاملEvaluation of Nitrogen Fertilizer on Yield and Yield Components of Bread and Durum Wheat Genotypes
The present study aimed at investigating the effect of different levels of nitrogen on yield and yield components of bread and durum wheat. To this end the experiment was conducted in 2010-2011 in south west of Iran as split plots based on randomized complete block design with three replications. Main plot included four levels of nitrogen 60, 120, 180, 240 kg.ha-1 and the sub plot included four...
متن کاملResponse of Marigold Flower Yield and Yield Components to Water Deficit Stress and Nitrogen Fertilizer
In order to study the effect of water deficit stress and different nitrogen levels on flower yield, yield components and water use efficiency of Calendula officinalis L., an experiment was conducted as split plot based on randomized complete block design with three replications, at research field of Islamic Azad University, Birjand branch in 2009. In this experiment, irrigation treatments (irri...
متن کاملManipulating Planting Density and Nitrogen Fertilizer Application to Improve Yield and Reduce Environmental Impact in Chinese Maize Production
Relatively low nitrogen (N) efficiency and heavy environmental costs caused by excessive N fertilizer applications with outdated fertilization techniques are current cultivation production problems with maize among smallholders in North China Plain. Although many studies have examined agronomical strategies for improving yields and N use, the integrated effects of these measures and the associa...
متن کاملeffect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars
این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
