evaluate the effects of iron nano-fertilizer rates (0, 1, 2 and 3 g l-1) planting density levels (10, 15, 20 40 cm) on fresh herb, essential oil content other traits under natural conditions. Traits such as number flowering branches (NFB), height first branch (HFB), secondary (NSB), stem diameter (SD), (EOC), dry mass (DM), yield (EOY), total anthocyanins (TA), chlorophyll a (CA), b (CB), flavonoid 270 nm (F270), 300 (F300), (TF) were measured. Results showed that nano Fe treatment × trait...

Two field experiments were carried out to study the response of Dracocephalum moldavica L. NPK fertilizer and different application techniques MOG organic in two regions Iran (Piranshahr with cold Mediterranean climate clay loam soil, Maragheh cool sub-humid temperate sandy soil). is bio-organic plant origin contains natural enzymes amino acids. In current following treatments have been applied: (a complete 20-20-20, 90 kg ha-1); MOG1 (soil at sowing stage); MOG2 (foliar early stage...

We conducted field experiments in two locations to investigation of organic and chemical fertilizer on soil characteristics essential oil yield dragonhead. Results showed that the inoculation bacteria with seeds location 1 also G1 genotype 2 than G2 increased total nitrogen content. The application azocompost its urea's comparing control, it increase carbon indicated by increasing content a linear procedure bulk density increased. 100% treatment had highest electrical conductivity soil....

Dragonhead (Dracocephalum moldavica L.) as an annual, herbaceous, essential oil-generating, spicy aromatic medicinal plant has oil at 0.06-0.92% depending strongly on environmental conditions. In order to evaluate the resultant composition of in herbage dragonhead samples gown under different conditions, filed experiments were performed five areas across Iran (L1: Maragheh, L2: Tehran, L3: Isfahan, L4: Khoy, and L5: Piranshahr). Upon harvesting plants full flowering stage, their essence...

Introducing grass pea genotypes with wide adaptability across diverse environments is important. Dry forage yield of 16 genotypes, tested in a RCBD design three replicates 4 locations over 3 seasons Iran. The GGE biplot method based on SREG model facilitated visual evaluation the best genotypes. first two principal components accounted for 77 % GE interaction and revealed six winning four mega-environments. average location coordinate (ALC) was used to examine both performance stability...

Dragonhead (Dracocephalum moldavica L.) is an annual, herbaceous, balm-scented and spicy medicinal plant of Lamiaceae family.An experiment was carried out during successive season to investigate the response dragonhead various sowing densities (10, 15, 20 40 cm) iron nano-fertilizer (0, 1, 2 3 g lit -1 ) applications.Iron a necessary element for plant's growth plants deficiency or deactivation show with chlorosis their leaves.Results ANOVA indicated there not any significant interaction...

Abstract This study was performed to the effects of farmyard manure (zero (M1), 20 (M2) t ha −1 ) and nano-fertilizers [control (n1), Mn (n2), Fe (n3), Zn (n4)] on sunflower. Traits days 50% flowering, maturity, leaf number, area, plant height, achene yield harvest index were measured.Treatment by trait (TT) analysis using biplot used determine which treatment best for what generated standardized values traits means. Results showed that first two principal components (PC1 PC2) create a...

Dracocephalum moldavica L., the Moldavian dragonhead, has found its place in folk medicine and been used to address kidney complaints. Pre-hydration methodologies were administered dragonhead seeds utilising nano-silicon dioxide at three concentrations: Si1 0 mM as control, Si2 Si3, 1 2 mM, respectively. Concurrently, treatments with nanoparticles of Fe oxide form encompassed: Fe1 Fe2 Fe3, A range parameters, including germination percentage, weight (fresh dry) length roots shoots, seed...

Abstract Nanotechnology is an emerging field of science widely exploited in agriculture recent years. In this investigation, application nanotechnology via some nano-particles (nano-iron and nano-silicon) have been investigated seed priming dragonhead. Seeds were subjected to pre-hydration treatments by factor nano-silicon dioxide as; (S1) 0 mM or distilled water, (S2) 1 concentration (S3) 2 nano-iron oxide (F1) Mm (F2) (F3) concentration. Germination percent, root fresh weight, shoot...

The thickness of the buccal bone and its covering gingiva is pivotal in determining prognosis implant therapy as well fixed orthodontic appliances, especially nonextraction treatments. purpose this study was to evaluate soft tissue maxillary anterior segment. This measured hard at 2 5 mm more apical from crest root apex, distance CEJ alveolar crest, using 80 CBCT images divided into three age groups. In addition, free measured. acquired data then analyzed an ANOVA, t-test, Pearson...

Headspace solid-phase microextraction (HS-SPME) using a type of SBA-15 was made more hydrophobic by modification with ethoxy trimethyl silane to obtain hybrid organicinorganic mesoporous nanocomposite, which then impregnated Nafion for the collection and detection volatile compounds Nepeta haussknechtii Bornm. Experimental parameters, such as sample weight, extraction temperature, humidity effect, desorption time, were examined optimized. Using HS-SPME followed GC–MS, 42 separated...

Effective management of nutrient application is important part the crop production puzzle and it seems that nano-fertilizers may have high potential for achieving sustainable production.A field experiment was carried out to investigate effect adding different nano-size biological fertilizers on maize growth under various irrigation regimes.The conducted optimal level (up ~50% capacity) which applied from beginning reproductive period.Fertilizer's treatments included control (Nf;...
