soil or water salinity is one of the major problems of agriculture in the arid and semiarid regions of the world, especially in iran. beside the salinity, reasonable canola production depends on nutrient supply so that increase in quantitative and qualitative yield is highly correlated with nutrients availability, especially nitrogen and zinc. in order to investigate the effects of the nitrogen...

in order to determine the appropriate amounts of potassium and nitrogen fertilizers to achieve high grain and oil yields of rapeseed (hyola 401) in paddy fields, a field experiment was conducted at rice research institute of iran (rasht) in a factorial experiment based on the complete randomized block design with 3 replications in 2008-2010. the first factor was the amounts of potassium fertili...

to investigate wheat and wild mustard growth and competition to n levels, an experiment was conducted in ramin agriculture and natural resources university of khouzestan, located at 36 km north of ahvaz. treatments included planting wheat solely, wild mustard solely, and intercropping wheat and wild mustard in pots. these combinations were exposed to n levels including 0, 60, 120 and 180 kg.ha-...

Nitrogen influence plant growth and yield of crops. To evaluate the potential different pre released rice genotypes at levels under Northern Telangana Zone. Experiment was laid out insplit plot design with five main plots (pre cultures) four sub (nitrogen levels) RARS, Jagtial, Kharif 2018-19 to Rabi 2019-20.
 Four cultures TelaganaZone viz., C1-KNM-733, C2- KNM-1638, C3- JGL 24423 C4: JGL...

Background: Nitrogen is the most important nutrient requirement for plants. Nitrogen supplying affected the leaf area, carbon fixation, glandular trichomes formation, ATP and NADPH content which resulted to the terpenoids biosynthesis enhancement and essential oils accumulation. Objective: This study was aimed to evaluate changes of essential oil content and components by use different levels ...

Cellular levels of an L-asparaginase in a Chlamydomonas species were found to be greater in nitrogen-limited batch cultures than in batch cultures grown in ample nitrogen. Cells grown in high nitrogen medium (5 mM NH4Cl) and suspended in nitrogen-free medium showed a 2- to 3.5-fold increase in activity after 24 to 48 h. This increase in activity was inhibited by cycloheximide and by the additio...
