Objective: Seed priming is the simplest and the best method to increase seed germination speed.Methods: To address this, in a study aimed at the effect of priming of different barley (Hordeum vulgare L.) cultivars on various germination characteristics, in the form of a factorial experiment was conducted using a completely randomized design with four replications in the research greenhouse of the Agricultural and Natural Resources Research Center of Hamadan province in 2022. Treatments including priming of seeds with fertilizers 1. Biozar, 2. Seafull amino zinc, 3. Sabzine, 4. Royesh, 5. Ecobooster, and 6. control (no fertilizer application), and different barley cultivars including Jolgeh, Bahman, Azaran, Abidar, Ghaflan, and Sahand.Results: The results indicated a significant effect of seed priming on the evaluated characteristics compared to the control treatment. The highest enzyme activities of catalase (0.117 Unit/ml) and peroxidase (85.08 Unit/ml) were obtained in seedlings obtained from seeds priming with Seafull amino zinc, which were 72 and 33% more than control treatments, respectively. The highest seedling vigor index was related to the seeds priming with seafull amino zinc fertilizer (26.55), which was significantly higher than the control treatment (22.84) and other treatments. Also, the germination percentage of seeds priming with seafull amino zinc fertilizer was significantly higher (3.5%) than the control.Conclusion: Considering that seed priming is a cost-effective and easy method and at the same time it is simple and does not require complex technical knowledge, it can be easily implemented by farmers. Therefore, this method is recommended to improve germination, seedling growth, and the quality and strength of barley seeds.

Excessive use of chemical fertilizers has caused contamination of soil as well as surface and groundwater resources. For this purpose, an experiment has been conducted to investigate the possibility of reducing surface water pollution with nitrate and also the effect of nitrogen on quantitative and qualitative characteristics of beans as a factorial based on completely randomized design (CRD) with four replications in Hamadan Agricultural and Natural Resources Research Center between 2013 and 2014. The first factor includes four types of nitrogen fertilizers, X1 (zeolite - EN), X2 (zeolite - AcAcEN), X3 (zeolite - HED), X4 (urea fertilizer), and X0 (control sample - no fertilizer use) and the second one involves two bean species, namely red beans (Phaseolus vulgarize L.) of Derakhshan cultivar and genotype 29005 of Cowpea (Vigna unguiculata L.). Applying functionalized zeolite nanofertilizers reduces nitrate leaching from the experimental units (pots). Meanwhile, zeolite X3 fertilizer is capable of reducing nitrate leaching by 48% in comparison with urea fertilizer. The amount of soil nitrogen in pots, containing X3 fertilizer, is 0.115 ppm and, compared to the urea fertilizer treatment, it improves this element’s maintenance in the soil by 30%. Accordingly, X3 fertilizer increases chlorophyll, protein, and grain yield by 44%, 64%, and 56%, respectively, in comparison with the control. In general, the application of functionalized nano zeolites has a beneficial role in reducing nitrate leaching and improving the quantitative and qualitative characteristics of bean plants.

In order to investigate the effect of biofertilizers on growth characteristics of maize (Zea mays L.) in lead contaminated soils, a experiment was conducted in a greenhouse of Faculty of Agriculture, Zanjan University in 2015, Factorial experiment based on a completely randomized design (CRD) in 3 Replication. The treatments included soil contamination levels of lead (0, 50, 100, 200 and 400 mg / kg soil), and inoculation with different bio-fertilizers was including phosphate solubilizing bacteria, Glomus museae mycorrhiza and the Glomus Intardis mycorrhiza. The measured factors included: leaf chlorophyll index, plant height, fresh and dry weight of root and shoot, and phosphorus and potassium of root and shoot. The results indicated that application of bio-fertilizers significantly increased leaf chlorophyll index, plant height, potassium, phosphorus, and weight of root and shoot significantly compared to control treatment. Glomus fungus and + solubilizing bacteria (M + P) improved the leaf chlorophyll content and plant height by 11.93% and 21.89%, respectively. With increasing levels of soil contamination to lead, leaf chlorophyll index significantly decreased. In general, the results showed that soil inoculation with biological fertilizers can be reduce the harmful effects of lead in plant growth.

To investigate the effect of nanofertilizers functionalized with two organic compounds in phosphorusreleasing and its influence on the growth parameters of bean plant, a factorial experiment was conducted based on a completely randomized design in 3 replicationsat the Agriculture Research Center of Hamadan in 2014. Fertilizer treatments including P0 (zeolite without functional group (control sample)), P1 (zeolite + AcAcEN ligand), P2 (zeolite + HED ligand) and P3 (triple super phosphate) and also twotypes of bean including the red beans (PhaseolusvulgarisL) and cowpea (Vigna unguiculataL.) were used. Results showed that in comparison with two other zeolite fertilizers,usingnanozeolite functionalized with HED ligandresulted in improving the quantitative and qualitativeparameters of bean. Compared with triple super phosphate, P2 fertilizer showed better results in the case of grain yield and plant phosphorus uptake and moreover, phosphorus leaching was lower in this fertilizer. The general results of this report is representative of the useful and effective role of nanozeolite functionalized with HED ligand in improving the growth parameters as well as qualitative and quantitative characteristics of bean plant.
