Nitrogen Remobilization and N-P-K Concentration of Wheats of Different Ploidy Levels Respond Differently to Nitrogen Supply

Response of Emmer and Durum Wheats to Different Levels of Nitrogen Fertilizer

Emmer tetraploid hulled wheats are considered as the ancestor of modern wheat and have considerable potential for durum wheat improvement, especially in terms of grain protein content. To investigate the response of emmer and durum wheats to different levels of nitrogen fertilizer, eight durum and four emmer genotypes were evaluated in the field during 2017 cropping season. The experiment was c...

Evaluation Seed Yield, Its Components and Protein Concentration of Wheat in Response to Different level of Nitrogen and Vermicompost

BACKGROUND: Management of nutrients, especially nitrogen, in order to have economic production, maintain sustainable agriculture and provide food security, is considered to have an important priority. OBJECTIVES: Current study was conducted to evaluate effect of different level of nitrogen fertilizer and vermicompost on quantitative and qualitative traits of w...

Reaction of the Green Bean- Safflower Intercropping Patterns to Different Nitrogen Fertilizer Levels

In order to investigate the effects of nitrogen fertilizer levels and intercropping ratios on yield and other morphological traits of two crops, field experiments were conducted during two years (2010-2011) in the research field of the school of Agriculture, Shiraz University, Shiraz, Iran. The study was carried out in a factorial experiment laid out based on a completely randomized block desig...

Nitrogen metabolism and remobilization during senescence.

Senescence is a highly organized and well-regulated process. As much as 75% of total cellular nitrogen may be located in mesophyll chloroplasts of C(3)-plants. Proteolysis of chloroplast proteins begins in an early phase of senescence and the liberated amino acids can be exported to growing parts of the plant (e.g. maturing fruits). Rubisco and other stromal enzymes can be degraded in isolated ...
