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 humic acid, iron and silicon nanoparticles on quantitative and qualitative yield and filling components of wheat seed under salinity conditions, a factorial layout was carried out based on a randomized complete block design with three replications in the research greenhouse of University of Mohaghegh Ardabili during 2021. Treatments included salinity levels (without salinity as a control, salinity of 35 and 70 mM by NaCl and without salinity as a control), foliar application of nanoparticles at four levels (no foliar application as a control, foliar application of 0.8 per liter of nano iron, 40 mg / l nanosilicon spraying, combined application of iron nanoparticles and silicon nanoparticles and no foliar application as a control) and humic acid spraying (spraying with water as a control and spraying 3 g/l. The results showed that combined application of humic acid and foliar application of 40 mg of iron and nanosilicon nanoparticles in the absence of salinity, increased maximum seed weight, seed filling rate, length and effective seed filling period, Spike length, 100-seed weight, plant height, number of seeds per spike, chlorophyll index (56.60, 1.183, 39, 58.45, 58.5, 39.53, 2.51, 70.6, and 57.57 respectively) and increased the yield of single plant (46.97%) compared to the conditions of non-application of humic acid and nano-oxides under the salinity of 70 mm of soil. Nanooxides (iron and silicon) can increase wheat seed yield of wheat under salinity stress conditions by improving seed filling components.

To study the effects of artificial seed ageing on germination indices in the laboratory condition and seedling establishment and yield of two red kidney bean genotypes in the field condition, an experiment was carried out at Research Field of Faculty of Agriculture, University of Tehran, Karaj, Iran in 2011. The two experiment design, were as factorial with four replications arranged in randomized complete blocks design (RCBD) and complete randomized design (CRD) for field and laboratory condition, respectively. The experimental treatments consisted of four levels of seed ageing – 0 (control), 2, 4 and 6 days seed ageing – and two red bean genotypes (Akhtar and Sayyad). Results showed that germination percentage, germination rate, normal seedling and seedling vigor index significantly decreased by seed ageing treatment in standard germination test. Also, seed ageing significantly decreased germination percentage, germination rate, seedling length and dry weight, normal seedling and seedling vigor index in accelerated ageing test. Studied genotypes was different in terms of germination percentage, germination rate, normal seedling, seedling length, seedling vigor index and electrical conductivity test. In the electrical conductivity test, seed leakage increased by increment of seed ageing level and is sever in Akhtar compared to Sayyad. In the field condition, seedling emergence and grain yield significantly affected by genotype and seed ageing. Seedling emergence index, seedling establishment percentage and grain yield decreased by seed ageing treatment that was severe in Akhtar than that of Sayyad genotype.
