Two field experiments were carried out during 2018–2019 at the Hamedan and Qom sites, which are different ecological locations of Iran. Hamedan was selected as a temperate climate and Qom as semi-arid to study some of the morphological and physiological traits of fodder beet in various climatic conditions. The experimental map was designed as a split–split-plot in the form of a randomized complete block with three replications. The main plots were assigned three levels of methanol (i.e., control, 15, and 30% by volume). The sub-plots were restricted to two glycine betaine (GB) concentrations (i.e., control and four grams per liter of methanol consumed, and the sub-sub-plots consisted of six different genotypes of fodder beet). The results showed that root length, root and foliage yield/ha, as well as sugar content increased with the incremental level of methanol and/or GB concentration. Foliar application of methanol and GB also significantly changed the qualitative parameters including sodium content, catalase value, crude protein percentage, and dry matter digestibility. It should be noted that two sites differed in most of the investigated traits, so that Hamedan treatment had a more active role on fodder beet growth, yield, and quality compared with Qom. Meanwhile, there was a significant difference between fodder beet genotypes. Generally, spraying fodder beet with 15%by volume methanol or GB with concentration of four grams per liter of methanol is the recommended treatment for raising forage yield under the ecological circumstances of this research.

The sowing date is an important factor for expanding the cultivated area of rapeseed and affects seed yield, oil content, and fatty acid compounds. Micronutrient elements play an important role in improving the vegetative and reproductive growth of the plant, especially under conditions of biological and environmental stresses. A two-year experiment (2014-2016) was performed to study the response of rapeseed genotypes to foliar application of micronutrients on different sowing dates. The treatments were arranged as a factorial-split plot in a randomized complete block design with three replicates. Three sowing dates of 7 (well-timed sowing date), 17, and 27 (delayed sowing dates) October and two levels of foliar application with pure water (control), selenium (1.5%), zinc (1.5%), and selenium+zinc (1.5%) were factorial in the main plots and five genotypes of SW102, Ahmadi, GKH2624, GK-Gabriella, and Okapi were randomized in the subplots (a total of 30 treatments). Seed yield, oil yield and content, oleic acid, and linoleic acid were reduced when rapeseeds were cultivated on 17 and 27 October, while the contents in palmitic, linolenic, and erucic acids, and glucosinolate increased (p < 0.01). a selenium+zinc treatment improved seed yield, oil content and yield (p < 0.01). The oil quality increased due to increased contents of oleic and linoleic acids under the selenium+zinc treatment (p < 0.01). The GK-Gabriella and GKH2624 genotypes are recommended to be sown on well-timed (7 October) and delayed sowing dates (17 and 27 October) and treated with selenium+zinc due to the higher oil yield, linoleic and oleic acids.

AbstractTo identify appropriate genotypes for breeding varieties suitable for semi-arid areas, yield components, as well as morphophonological traits of 127 safflower genotypes, were assessed at the Seed and Plant Improvement Institute, Iran. Cluster analysis revealed four distinct groups. The largest group (third cluster) includes 48 genotypes with characteristics such as mostly yellow-coloured flowers, mostly thorny with few thistle genotypes, relatively early-flowering, relatively high number of heads and grains per plant, highest 1000-grain weight with the highest grain yields. In contrast, the smallest group (second cluster) contains 13 genotypes with characteristics such as yellow florets, semi-dwarf, thorny, moderately late-flowering, low number of heads per plant and number of grains per head, low 1000-grain weight, and low grain yield. Principal component analysis results showed that the three components accounted for 29.5, 15.9 and 11.1% of the total variation, respectively. Graphic representation of the biplots based on the first and second principal components showed that the experimental genotypes were classified into four groups. The results also indicated that stem diameter, the number of branches, heads per plant and grains per head had the highest correlation with the first component, and grain yield, flower colour, flowering initiation and plant height had the highest correlation with the second component. These traits can be considered as an appropriate index for the selection of elite safflower genotypes for breeding varieties suited to cultivation in semi-arid conditions.

Pseudomonas infections are an important cause of morbidity and mortality and saprophytic fungi are now increasingly being recognized as serious pathogens in immunocompromised patients.To investigate the effect of using bio-materials on mammalian tissues,two experiments were designed;the first one was feeding of Balb/c mice with irrigated lettuce with bio-fungicide (mutant and wild)and bio-fertilizers prepared with Pseudomonas (p) fluorescens, p. putida, p. aeruginosa, and the second was the usage of drinking water containing (Trichoderma (T) spores (mutant and wild) or P.fluorescens, P.putida, P.aeruginosa suspensions). Then, blood factors and inflammation of tissues (liver, kidney, spleen and large intestine) in all mice were analyzed after two months. Blood samples were taken from the mice to examine some of the hematological (RBC, MCV, MCH, MCHC) (data not shown) and biochemical (AST, ALT, ALP) factors, and also observed under a microscope. The study of tumor marker carcinoembryonic antigen (CEA) in all treatments showed that the strains in these bio-fertilizers did not stimulate carcinogenic indices.The results from the other blood factors were normal for all strains (data not shown).Only P.putida showed no adverse effect on the increase in alkaline phosphatase (ALP).The results also showed that the effect of bio-fungicide on mammalian tissues (spleen and large intestine) was normal. But a small number of mild liver necrosis was seen in the treatment groups with wild Trichoderma, and moderate necrosis in the the liver tissue after treatment with mutant Trichoderma isolates.More investigation should be made to determine the impact of these biotic factors on the mammalian tissues before commercialization.

Abstract Mullein (Verbascum songaricum Schrenk.) is the biggest plant species belonging to the Scrophulariaceae family. The aerial parts of V. songaricum, especially leaves and flowers are used as herbal medicine by indigenous peoples of some regions of Iran. The effects of two planting patterns (square and rectangular) and different irrigation regimes, including irrigation in 90-85 % field capacity (F.C.) or control (I1), irrigation in 60 % F.C. (I2), irrigation in 45 % F.C. (I3), and irrigation in 30 % F.C. (I4) on some phenolic compositions, Malondialdehyde (MDA), catalase enzyme (CAT), proline, and growth parameters of V. songaricum as a new medicinal crop have been investigated. Field experiment was done two consecutive years (2016–17) in semi-arid climate, Southwestern Iran. Total phenolic contents of the ethanol extract from the leaves (2016 and 2017) and flowers (2017) determined by Folin–Ciocalteu assay and phenolic acids and flavonoid compositions of the flowers separated and quantified each component by high-performance liquid chromatography (HPLC). Results indicated that the planting patterns had not significant effects on biochemical and phytochemical features, however, the highest values of shoot dry weight and stem height were obtained from the plants cultivated in the rectangular pattern, and also the maximum dry weight of flowers was achievement from the mullein cultivated in the square pattern. Reduced irrigation significantly increased the contents of MDA, CAT, proline, and secondary metabolites such as total phenolic, phenolic acid (gallic acid), and flavonol quercetin, whereas, photosynthesis pigments and growth parameters (chlorophyll a, chlorophyll b, total chlorophyll contents, canopy diameter, plant height, and dry herbal weight) significantly decreased under deficit irrigation. In conclusion, reduced irrigation under the rectangular pattern significantly increased the amounts of total phenolic and flavonoids in the extracts from the leaves and flowers. Finally, the results of this study can be used in agricultural systems in order to growth, development and increase the quantity and quality yields of V. songaricum under reduced irrigation.

In order to investigate the effect of magnesium oxide (MgO) and iron oxide (Fe2O3) nanoparticles (NPs) on physiological traits and the yield of sour tea (Hibiscus Sabdariffa L.), a factorial experiment was conducted in a randomized complete block design (RCBD) with four replications in 2018. MgO and Fe2O3 were used in concentrations of 0.01% and 0.03% as foliar application. The results showed NPS improved chlorophyll (Chl) content and index. The highest total chlorophyll was obtained in plants treated with 0.01% of MgO and 0.0.3% of Fe2O3. Catalase (CAT) and peroxidase (POX) activities significantly increased with NPs, in which all combined concentrations of NPs had greater enzymes activities compared to control. The seed weight in plants treated with 0.03% of MgO and 0.01% of Fe2O3 was higher compared to non-NPs treatment. The highest mucilage yield was found at 0.01% of MgO and 0.03% of Fe2O3. Total flavonoid content (TFC) in plants treated with 0.01% of MgO and 0.01% of Fe2O3 was higher than other experimental treatments. The treatment including 0.01% of MgO and non Fe2O3 had lower anthocyanin content compared to other combined levels of NPs. Carotenoid increased with medium concentrations of NPs, but decreased with high level of NPs (0.03%). Protein concentration at 0.01% of MgO and 0.03% of Fe2O3 and 0.03% of MgO and 0.01% of Fe2O3 was higher than other experimental treatments. According tour results, we suggest the use of 0.01% of MgO and 0.03% of Fe2O3 for improving the physiological properties of sour tea.

The present study was carried out to assess the effects of bio-organic and inorganic fertilizers on plant nutrients, essential oil composition and antioxidant capacity of Satureja macrantha L. The experiment included nine treatments viz., NPK (50:25:25 kg ha−1), Vermicompost (VC) (5 t ha–1), NPK +VC, Thiobacillus (T), T+VC, T+sulfur (S) (250 kg ha−1), T+S 500 kg ha−1, Glomus mosseae, and control (untreated plants). The results showed the highest Essential Oil (EO) content and yield were respectively observed in plants treated with the combination of VC and NPK. Total Phenol Content (TPC) in first-year plants treated with VC and second-year plants under NPK+VC were higher than other experimental plants. Total Flavonoid Content (TFC) in second-year plants under the combination of NPK was greater than other plants. N content in first year plants treated with NPK fertilizer / combination of NPK and VC was higher compared to other experimental plants. The highest P content was observed in the NPK application in first year. Gas Chromatography—Mass Spectrometry (GC/MS) analyses revealed that the main constitutes of S. macrantha EO were p- Cymene (16.30-34.64%), γ-terpinene (15.46-33.6%), and Thymol (14.82-43.09%), which had different responses to sampling time and fertilizer treatments.

ABSTRACT Satureja mutica is a medicinally important plant, which may be affected by organic fertilizers and cultivation methods. To investigate the effect of cattle manure (30 ton/ha) and wheat straw (10 ton/ha) as organic fertilizers and plant density (80000, 40000, and 26666 plan ha−1), an experiment was carried out as split plot with three replications during 2017 and 2018 on plant yield, total phenol content (TPC), total flavonoid content (TFC), essential oil (EO) yield and composition of S. mutica in the rainfed condition. The results showed that the highest fresh weight yield (FWY) and dry weight yield (DWY) were observed in high plant density in second year. TPC in interaction of second year and cattle manure was higher than others. The greatest TFC was observed in plants supplied with interaction of second year and wheat straw. EO content and yield in plants treated with the interaction of second year and high plant density were higher compared to those in other plants. The GC/MS analysis showed that the main EO components were thymol, carvacrol, γ-terpinene and p-Cymene, representing different concentrations by using the organic fertilizers and plant densities. In summary, the use of cattle manure and high plant densities can result in higher plant production.

To assess the response of promising safflower genotypes to late-season drought stress in delayed planting conditions, an experiment was conducted in two years (2016–2017 and 2017–2018) in Iran. The irrigation regime was specified in two levels, including normal irrigation and irrigation cut off in the seed filling stage in main plots, and five safflower genotypes, including Soffe, Goldasht, Golmehr, Padideh, and Parnian were categorized in subplots. Applied drought stress significantly reduced the seed yield and yield components of all genotypes, which accompanied with a substantial decrease in oil content and oil yield of all genotypes. However, the highest seed and oil yield in drought stress conditions obtained in the Parnian genotype by value 2338 and 561 kg/ha, respectively. Moreover, a significant drought-induced increase in palmitic, stearic, and oleic acids, as well as a decrease in linoleic acid content, was observed in all genotypes. Parnian genotype with high unsaturated fatty acids content (90.9%) and the minimum amount of saturated fatty acids (8.7%) might be a promising genotype to starting a formal crop improvement program to achieve more drought-tolerant safflower genotype.

Dodder (Cuscuta campestris) control is a challenge and dodder is one of the factors limiting the cultivation of sugar beet in many regions of Iran. New herbicides can be useful in chemical control of dodder. This study was conducted to evaluate the effect of new mixture of herbicides on dodder control in sugar beet field. Results showed that the Propyzamide (3 L ha) had the highest effect on dodder weed weight loss% and this treatment led to 99.59% reduction in its fresh and dry weight. In addition, herbicide treatments were significant at 0.01 significance level within 15 and 30 days; after this time application of Propyzamide 3 L ha led to 90.63 and 100% reduction in dodder weed, respectively. The Propyzamide 3 L ha led to 80.63% increase in sugar beet foliage dry weight within 30 Days After Herbicide Application (DAHA). In addition, between treatments the highest increase percentage of sugar beet yield was obtained by Ethofumesate (2 L ha) along with Gallant Supper (1 L ha) and the removal of broad leaf about 86.55% compared to control. Totally, Propyzamide (1.9 L ha) along with Gallant Supper (0.75 L ha) showed the best results with the lowest dosages.

Today, weeds control is very difficult because they are resistant to the herbicide due to excessive use of chemical herbicides in agriculture. Many studies have shown that mechanical and biological control of weeds can be much less damage to the environment of chemical herbicides. Develop of biological herbicides in agriculture was slow due to high prices and this subject the researchers to move toward the elimination of agricultural weed mechanically. This work was originally done by a many number of workers because and workers' rights didn't work was ultimately economic value. Now solve this subject by the use of robotic technology in agriculture has been studied and a many number of agricultural researchers with the help of computer scientists move towards making robots to remove the weeds. Of course this is difficult due to excessive weeds similar to the plants, but the final results will help to increase crop and save the environment by eliminating chemical herbicides.
