Camelina, an oilseed plant in the Brassicaceae family, is extensively utilized in the food and pharmaceutical industries. This study aimed to investigate the effects of micronutrient foliar application on the growth and yield traits of two camelina genotypes (Soheil cultivar and Line-69) during the periods 1400-1401 and 1401-1402 at the Agriculture Research Station of Ferdowsi University of Mashhad,, Iran. The experiment was conducted as a factorial design based on a completely randomized block with three replication, considering line and cultivar. The applied treatments included foliar application of iron sulfate, zinc sulfate, manganese sulfate, a mixture of micronutrients (iron sulfate, zinc sulfate, manganese sulfate), distilled water, and a control. These treatments were applied at two stages: 50% flowering and 50% pod formation. The experiment was conducted as a factorial design based on a completely randomized block with three replication, considering line and cultivar. The results of mean comparison revealed that, over two cropping years, the highest 1000-grain weight (1.20 grams) was attained in the Soheil cultivar during the 50% flowering stage in the first crop year, following the application of manganese sulfate via foliar application. The highest number of pods per plant (214 pods) was also observed in the Soheil cultivar during the 50% flowering stage, achieved through foliar application of iron sulfate in the second crop year. Under the influence of cultivar, the highest seed yield per hectare was obtained in the Soheil cultivar (1930 kg/hectare).

In order to investigate the effect of water deficit stress and sources of nitrogen fertilizer on germination quality and vigor of wheat seeds of Chamran cultivar, an experiment was conducted in Agricultural Research Center of Fars province. In this experiment, wheat seeds were first treated at three levels of water deficit stress (complete irrigation, water deficit stress in milky and rough stage) and four levels of nitrogen fertilizer sources (urea fertilizer 100% plant requirement, urea fertilizer 25% Along with nitroxin and nitrogen, 50% urea fertilizer with nitroxin and nitrogen, 75% urea fertilizer with nitroxin and nitrogen were produced. Then, the quality and vigor of the seeds were tested in two standard experiments of germination and accelerated aging in a factorial design with four replications. The results showed that the effect of experimental treatments on all measured traits except germination percentage was significant. Water deficit stress and sources of nitroxin and nitrogen fertilizer with 25% urea at the beginning of decline led to an increase in protein concentration (12.39%), but the lowest amount of starch (20.85 %) under the interaction of nitroxin and nitrogen fertilizer with 75% urea in 48 hours Deterioration was observed. Water deficit stress also increased the concentration of soluble sugars and decreased the grain alpha-amylase enzymes. Overall, the results of this study showed that the use of combined treatments of urea fertilizer and biofertilizers in stress conditions to feed the mother plant led to the production of seeds with higher vigor and more resistance to decay.
