In order to evaluation of some morphological and chemical characteristics of quinoa, split plot experiment was conducted in a randomized complete block design with three replications 2019-2020 cropping season, at the Agricultural Research station of University of Zabol, Iran. Vermicompost at three levels (0, 5 and 10 ton/ha) considered as main factor and chemical fertilizer at four levels (25, 50, 75 and 100%) considered as sub-factor. The main effect of vermicompost was significant on morphological traits such as plant height, 1000-seed weight, biological yield, grain yield and harvest index. Interaction of vermicompost and chemical fertilizer was significant on chemical properties including proteins and photosynthetic pigments. Application of 10 tons of vermicompost per hectare led to the maximum level of plant height, 1000-seed weight, biological yield, grain yield and harvest index. Also, the highest amounts of photosynthetic proteins and pigments were achieved from combined application of 10 tons/ha of vermicompost and 50% chemical fertilizer (25 kg/ha Urea + 50 kg/ha triple superphosphate + 50 kg/ha potassium sulfate). Totally, results showed the positive effects of vermicompost on the morphological and chemical properties of quinoa. It can be concluded that the combined use of chemical fertilizers and vermicompost can increase the yield of quinoa while reducing the use of chemical fertilizers and thus reduce the environmental impacts caused by them.

The experiment was performed based on a randomized complete block design) RCBD( with a factorial arrangement consisting of three replications. The first factor consists of four different ecotypes of dragon’s head) Kurdistan, Takab, Nazarkahrizi and Kalibar( and the second factor were included three anti-transpirant compounds )kaolin with a concentration of 5 Percent, chitosan with a concentration of 1 Percent and Ista with a concentration of 2 Percent( and no anti-transpirant )control(. The results showed that using anti-transpirants increased the amount of the activity of catalase and peroxidase enzymes. Ista anti-transpirant had a greater effect on enzyme activity than kaolin and chitosan. The highest amount of peroxidase and catalase )0.51-0.39 unit mg /protein( were obtained respectively from the ecotypes of Kurdistan treated with Ista and in Karaj cultivation. In addition, the highest grain yield and biomass yield were obtained from treatment with chitosan, which increased (4-20%) compared to the control, respectively. Based on the results, using anti-transpirants in dryland cultivation conditions improved most of the studied yield traits and biochemical traits compared to the control.

Combining organic and chemical fertilizers is one of the most important ways to achieve sustainable agriculture. In order to investigate the effect of organic fertilizers with chemical fertilizers on yield, yield components and quality traits of sunflower, a factorial experiment was conducted in a randomized complete block design with three replications in spring 2018 at Gonbad Kavous University farm research. Cultivar factor was included Haysan 25 and Oscar and combination of fertilizer factor was included no fertilizer application, 100 kg N/ha, 50 kg N/ha, 50 kg N/ha + 1.5 kg humic acid/ha, 50 kg N/ha + 0.5 kg Vita free/ha and 50 kg N/ha + 1.5 kg humic acid + 0.5 kg Vita free/ha. The results showed that the effect of cultivar and fertilizer on most of the measured traits was significant. Oscar cultivar produced higher grain yield, biological yield and oil percent and oil yield than Haysan 25 cultivar. Grain yield, oil yield, biological yield and plant height in 100 kg N/ha treatment was higher than other fertilizer treatments but was not significant difference with 50 kg N/ha + 1.5 kg humic acid/ha + 0.5 kg Vita free/ha treatment. Based on results, in order to achieve the maximum seed and oil yield of sunflower and to prevent excessive use of chemical fertilizers, the combined use of Nitrogen fertilizer, humic acid and vita free is necessary.

Despite the progress of the livestock industry in Iran, the production of forage plants commensurate with this development has not been considered. Therefore, this study has been conducted during 2017, with the need to produce feed for livestock and poultry and with the aim of determining the best density and planting date on quantitative and qualitative characteristics of Guar forage. Taking place in the Rasht Rice research Institute-station located in the Village of GilPordehsar in the Sangar city, it evaluates four planting date (May 12, May 26, June 9, and June 23) and three plant densities (200, 400 and 600 plant.ha-1) factorially in a randomized complete block design with three replications. Results show that the planting date of May 26 and the density of 600 plant.ha-1 in terms of fresh forage yield (35.02 t/ha), crude protein (19.02%), dry matter (54.35%), and carbohydrate (26.12%) are superior to other planting dates and plant density under test. The highest yield of dry forage (6.1 t/ha) and neutral detergent fiber (58.23%) has been observed on May 12 and a density of 600 plant.ha-1. The amount of crude fiber has increased with delay in planting, but the percentage of Ash is not affected by different planting dates and densities. According to the results, in order to obtain the highest quantity and quality of forage in Guilan Province, the planting date of May 26 and the density of 600 plant.ha-1 is recommended.

In order to investigate the effect of deficit irrigation on quantitative and qualitative characteristics of wheat (Triticum asetivum L.) Morvareed cultivar, an experiment has been carried out with three main treatments including surface drip irrigation (TS), subsurface drip irrigation (TSS), and Furrow irrigation (F), as well as three submain treatments containing irrigation levels 50% (I1), 75% (I2), and 100% (I3) of the plant water requirement. It has taken place in the research farm of Ardebil Agricultural Research and Training Center in Moghan region during 2016-2017. The experiment is conducted as split plot based on randomized complete blocks design with three replications. Results show that the highest 1000-grain weight, harvest index and number of tillers per unit area are obtained with 0.05 kg, 42% and 448.56 in I3 and protein content with 9.56% in I1, respectively. Also, the highest grain yield (7122.33 kg ha-1) is obtained from the TS with irrigation level of I3 (no significant difference between I3 and I1). Meanwhile, the highest water productivity based on grain yield with 1.81 kg m-3 is obtained from the treatment of F with I1. The lowest grain yield with 2866.67 kg ha-1 and water productivity based on grain yield with 1.05 kg m-3 belongs to F with irrigation levels of I1 and I3, respectively. Therefore, the surface drip (TS) with 75% (I2) and 100% (I3) of crop water requirement in conditions of water deficiency and no-water-deficiency, respectively, can be considered as optimum methods for wheat production in the Moghan region.

Some medicinal plants have an important role in production of fodder with high quality. While reducing the production costs, they protect the environment, water, and soil resources. On the other hand, mixed cultivation and application of organic and biological fertilizers or proper combination of these two with chemical fertilizers can be considered a solution to increase crop yield in sustainable agriculture. For this purpose, in order to investigate the effects of different treatments of fertilizer and ratios of mixed cultivation of Chicory and annual Medic, a factorial experiment has been conducted in a randomized complete block design with three replications at the experimental field located in Behbahan city in 2019-2020 growing season. The first factor has been different fertilizer sources (Chemical, Organic, and Integrated) in three levels: chemical fertilizer, vermicompost fertilizer and combined fertilizer (nitroxin biofertilizer + fertile phosphate 2 + 50% chemical fertilizer) and the second factor has been five intercropping patterns including: sole chicory (SC), sole annual medic (SM), one row of chicory: one row of annual medic (C1M1), one row of chicory: two rows of annual medic (C1M2) and two rows of chicory: one row of annual medic (C2M1). The studied traits are forage yield of chicory and annual medic and quality characteristics of forage including percentage and yield of crude protein, percentage of ash, crude fiber, dry matter digestibility, calcium, and phosphorus content of forage. The results show that the highest dry forage yields of chicory and medic (4.04 and 4.63 t/ ha, respectively) are obtained in monoculture and chemical fertilizer treatment. Mixed cultivation ratios and application of combined fertilizers and vermicompost improve crude protein and ash of medic and crude fiber of chicory forage without reducing any other quality traits. Evaluation of land equivalent ratio show the superiority of all mixed ratios over monoculture of these plants. Finally, mixed cultivation treatments C1M1 and C2M1 with a land equivalent ratio of 1.3 and a total yield of 5.44 and 4.95 tons per hectare and the application of combined fertilizer are recognized as superior treatments.

In order to achieve optimum quantitative and qualitative yield of potato in each region, new cultivars need to be compared. As such, this study has been carried out to compare 13 new potato cultivars along with two cultivars of Agria and Banba with each other to identify suitable cultivars for leaf area index, agronomic, and qualitative traits under climatic conditions of Razan. The statistical design, used in the present study, has been complete randomized block with three replications. Results show that Manito cultivar has reached the maximum leaf area index later than other cultivars, having 12 tubers per plant, which is 112% and 83% superior to Banba and Agria, respectively. Also, Natascha cultivar with a leaf area index of 3.65 has been 57% and 19% leafier than Agria and Banba, respectively. Tuber weight in Ottawa (157.8 g per tuber) has been 70.5% and 20.4% greater than Agria and Banba, respectively. Manito cultivar yields 71399 kg/ha, which is 123% more than Agria and 70% than Banba. Protein percentage of tubers in this study do not differ among the potato cultivars, while the difference is significant among the potato cultivars in tuber starch percentage and the highest values belong to Manito (18.09%) and Ottawa and Concordia cultivars, in the second and place. Generally, Manitou, Caruso, and Faluca cultivars are recommended for planting in the Razan on the basis of traits of maximum leaf area index, number of tubers per plant, and tuber yield.

In order to study the effect of nitrogen and irrigation interval on quantity traits and protein of mung bean (Vigna radiata L.), a factorial experiment based on randomized complete block design was conducted with three replications at research farm of Gonbad Kavous University during 2016. Interval irrigation factor was at three levels including irrigation each 10, 20 and 30-day, nitrogen fertilizer in three levels of non-application and application of 50 and 100 kg per hectare and mung bean genotypes in two levels of VC-1973A and Partov. The results showed that the highest grain yield was obtained from 30-day irrigation interval with 100 and 50 kg per hectare nitrogen and the lowest grain yield was obtained from 10–day irrigation interval and 100 kg nitrogen/ha and non-application treatment and also 20–day irrigation interval and non-application of nitrogen/ha. Grain yield in VC-1973A was 72.52% higher than partov gernotype. The highest protein percentage was obtained from irrigation interval of 30-day and the lowest was obtained from 10-day irrigation interval. With increasing of nitrogen consumption, protein percentage increased but proline decreased. Increasing of irrigation intervals from 10 to 30-day increased the amount of proline in mung bean genotypes. Protein percentage and amount of proline in Partov was 9.49% and 29.66% more than VC-1973A. In addition, although in some traits Partov was superior but in more traits especially grain yield VC-1973A was better than Partov and increasing of interval irrigation and nitrogen consumption created better conditions for mung bean production.

Evaluation the effect of drought stress and foliar nutrition of iron nano-chelate and fulvic acid on grain yield and fatty acids composition in seed oil of two sesame cultivars was conducted during a factorial split-plot experiment based on randomized complete block design with three replicates in 2017 in the Research Farm Shahed University of Tehran. The experimental factors included drought stress in three levels: full irrigation as control, irrigation up to 50% seed ripping, and flowering, as well as four treatments of foliar nutrition by iron nano-chelate and fulvic acid in Dashtestan and Halil cultivars. The results showed that the drought stress reduced grain yield and also, seed oil content. The highest grain yield was observed in full irrigation (2303.3 kg/ha) and the co-application of iron nano-chelate and fulvic acid (2246.4 kg/ha). Halil cultivar had the highest mean of the total number of capsules (81.19), number of seeds per plant (4786.1), 1000-grain weight (3.21 g), grain yield (2172.7 kg/ha), and biological yield (13534.6 kg/ha) in compared with Dashtestan. The highest oil and protein yield were observed in full irrigation and irrigation up to 50% seed ripping. Irrigation cut off at 50% flowering and seed ripping had the highest oleic and linoleic fatty acids compared to the control treatment, but the highest palmitic and stearic fatty acids were obtained in full irrigation treatment (10.86 and 10.73%, respectively). Halil and Dashtestan cultivars had the highest unsaturated and saturated fatty acids, respectively.

In order to evaluate the effects of chemical, biological and nano fertilizers on the yield and quality traits (oil and protein) of sesame seeds under different irrigation regimes an experiment was conducted as a split-plot factorial based on completely randomized blocks design with three replications at Shahed University during 2015-2016 growing seasons. Irrigation withholding levels (full irrigation (control) and irrigation withholding at 65 and 75 BBCH (codes of phonological stages that are equivalent to 50% of flowering and seed ripening respectively) were assigned as main plot and different nitrogen combinations (nitroxin, urea, and a mix of 50% nitroxin plus urea), various combinations of potassium (not used, nano-potassium foliar application (2 per thousand), irrigated use of potassium dioxide (2 L ha−1) and soil application of nano-potassium (2 kg ha−1) were allocated in the subplots. The highest number of per-plant capsules (19.26 numbers) was observed with irrigation up to 50% seed ripening and the use of urea together with the potassium nano chelate foliar application. The greatest grain yield and protein content and yield were obtained in irrigation up to 50% seed ripening in the absence of potassium fertilizer and nitroxin usage (1340.5, 276.53 kg ha−1 and 5-20%, respectively). The oil yield was utmost in irrigation up to 50% flowering and foliar application of potassium nano chelate together with the mixed system of 50% urea fertilizer plus nitroxin with average values of 47.96% and 550.46 kg ha−1, respectively. The use of nitroxin as a nano-bio-fertilizer and foliar application of chelated nano potassium in irrigation withholding conditions up to 50% grain aggregation resulted in increased grain yield (approx. 15% compared to the control) as well as improved quality of sesame seeds.

The effect of methyl jasmonate (MeJA) vapor treatment on antioxidant enzymes activities and vase life of gerbera cut flower was investigated in this experiment. This research was conducted as a split-plot experiment based on completely randomized design with three replications at the laboratory of the postharvest physiology, College of Agriculture, Tarbiat Modares University in 2013. Gerbera flowers were harvested at early morning from a commercial greenhouse and cut flower stems were put in a preservative solution containing 200 mg/L 8- hydroxyquinoline sulfate and sucrose 3%, exposed to 0, 0.1, 0.2 and 0.3 µlL−1 MeJA with 20 µlL−1 ethanol and control for 24 h. The results showed that MeJA significantly increased vase life and improved postharvest characteristics of cut gerbera flowers. MeJA 0.2 µlL−1 treatment extended the vase life to 15.67 days, compared to the control and ethanol treatments. Minimum of petal wilting symptoms were revealed in samples treated with MeJA. The lowest malondialdehyde and lipid peroxidation rates were also observed in MeJA treatments that they had a significant difference with ethanol and control. MeJA treatments resulted in increasing antioxidant enzymes activity and protein content compared with ethanol or control.

To decrease the use of chemical fertilizers and improving the yield and yield components of sunflower, a field experiment was conducted at the Research Farm of Tarbiat Modares University in 2014 and 2105. Three irrigation regimes (irrigation after depleting 40, 60 and 80% of soil water at field capacity (FC)), three soil fertility systems (100% farmyard manure (35% chicken manure + 65% sheep manure), 50% farmyard manure + 50% chemical fertilizer and 100% chemical fertilizer (urea)) and three zeolite rates (0, 5 and 10 ton ha-1) were studied in a split factorial arranged in a randomized complete block design with three replications, with irrigation regimes as the main plots, and factorial combination of the other two factors as the subplots. Over two experimental years, there were significant increases in grain yield and water use efficiency by applying either 100% farmyard manure (28.2 + 14.6 ton sheep + chicken manure ha-1, respectively) or integrated fertilizer (14.1 + 7.3 ton sheep + chicken manure ha-1, respectively plus 65 kg urea ha-1) with 5 or 10 ton zeolite ha-1 under all irrigation treatments. Based on the results, irrigation after depleting 40% of soil water at FC was revealed as a most performance of all treatment combinations. The highest oil and protein concentrations of grain were obtained with zeolite application under non-stress conditions. Chemical fertilizer application increased grain protein concentration, while organic manure increased grain oil concentration.

The performance of nine different linseed cultivars studied in a randomized complete block design (RCB) with four replications in Varamin region (Iran) in 2006. The traits were seed yield, fatty acids, protein and oil content of linseed. The difference between cultivars was significant for all traits (P< 0.01). The Legina cultivar had the highest seed yield (3000 kg/ha) and linolenic acid content (45.16 percent). The palmitic acid content of RH 14/05 cultivar, oil percent and stearic acid of GOLDA cultivar, and protein content and yield of native cultivar were higher than other cultivars (p< 0.05). The RH 14/05 cultivar which was low in linolenic acid and high in oleic acid can be used as a breeding line to produce oil.
