In order to determine the rosemary (Rosmarinus officinalis L.) dry matter and weeds under different fertilizer sources, an experiment was conducted as a split plot in a randomized complete block design with three replications at Sari Agricultural Sciences and Natural Resources University in 2016. The treatments consisted of: competition between plants and weeds (weedy check and weed free) as the main factor, and sub factor was fertilizer sources included sheep manure, vermicompost, sheep manure + vermicompost, NPK chemical fertilizer (N 46%, P2O5 46%, K2O 50%), NPK nano fertilizer and control (no fertilizer). The results showed that interference with weeds caused rosemary shift the maximum dry matter to the upper layers of canopy (20-40 cm). While in weed free treatment, rosemary had higher ability and uniformity in dry matter distribution in the two primary canopy layers compared to competition with weeds. In this regard, vermicompost treatment was successful with a mean of 49.51 g plant-1. Studies on density and weed biomass showed that the use of vermicompost (treatment 2) reduced density and biomass of weeds, while the chemical fertilizer caused the highest weed density and biomass. The results showed that the use of organic fertilizers such as vermicompost, not only reduce the use of chemical fertilizers and do not have environmental consequences, but also have the high ability to suppress weeds growth and decrease weed density and biomass.

In order to investigate the effects Azoto of irrigation cutting and chemical and biological fertilizers, Azoto Barvar 1 and phosphate Barvar 2 on grain yield, essential oil and biochemical properties cumin, an experiment was conducted as split plot based on a randomized complete block design with three replications at the University of Zabol Research Farm during 2016. Main plots included four levels of irrigation cutting; conventional irrigation, irrigation cutting in between stem elongation to flowering, irrigation cutting in between flowering to beginning of the grain filling period and irrigation cutting in between beginning to end of grain filling period. The subplot was the different type of phosphorous fertilizer including control (no fertilizer application), Azoto Barvar 1 and Phosphate Barvar 2 and triple superphosphate. Results indicated that the interaction of irrigation cutting and phosphorous fertilizer was significant on seed yield, oil percentage, carbohydrates, proline, total protein, absorption of nitrogen, phosphorous and potassium. The greatest seed yield, oil percentage, total protein, nitrogen, potassium and phosphorus obtained at conventional irrigation along with the application of Azoto Barvar 1, while the greatest proline was achieved at irrigation cutting between beginnings to the end of grain filling period along with the application of triple superphosphate. The greatest carbohydrate was observed at irrigation cutting between beginnings to the end of the grain filling period along with the application of Phosphate Barvar 2. In conclusion, results indicated positive effects of biofertilizers on the improvement of nutritional conditions of plants under irrigation cutting conditions

In this study, the quantity and quality of essential oil (EO) of chamomile cv. ‘Bodegold’, Moldavian dragonhead cv. ‘SZK1’ and fennel cv. ‘Soroksari’ were evaluated in Shahrekord climate condition in Spring 2014, Shahrekord University. Chamomile’ flowers and dragonhead’ herb were harvested at full flowering stage. Fennel’ fruits were harvested at waxy and full-matured stages. The EO content of each sample was extracted using a Clevenger-type apparatus, and then was characterized by gas chromatography and gas chromatography with mass spectrometry methods. The EO content of chamomile, Moldavian dragonhead, fennel (waxy) and fennel (mature) was 0.69%, 0.35%, 4.9% and 4.4%, respectively. The main constituents detected in the chamomile EO were α-bisabolol oxide A (43.57%), β-Farnesene (24.09%) and α-bisabolol oxide B (10.34%). Geranyl acetate (27.29%), geranial (24.64%), neral (20.93%) and geraniol (18.54%) were the most abundant components of the EO in dragonhead. The main component of EO in fennel in waxy and mature stages was trans-anethole, but its content in maturity was higher than that in the waxy stage. In conclusion, chamomile, Moldavian dragonhead and fennel showed promising characteristics in terms of EO content and composition in Shahrekord climate condition.

In order to assess soybean, sweet basil and borage yield intercropping system, an experiment wasconducted based on randomized complete blocks design with 9 treatments and three replicates in 2011.Treatments were consisted of replacement ratios of 75: 25, 50: 50, 25: 75 soybean: sweet basil and borageand pure culture of each plant. The results showed that the first pod in 75: 25 soybean: borage and solecropping of soybean observed to be positioned at upper height than other treatments. The node number ofstem was more in intercropping treatments than sole crop. In intercropping treatments, the pod numberper plant except 25: 75 soybean: borage and seed number per plant except 25: 75 and 50: 50 soybean:borage was higher than sole crop. Seed yield and biological yield was decreased by increasing sweet basiland borage proportions in intercrop except 75: 25 soybean: sweet basil. The seed yield and dry weight ofplant of intercropping was higher than pure culture of soybean. Yield of sweet basil in both growth periodand also seed yield of borage was decreased through increasing soybean presence. Area-time equivalentratio indicated 9, 11 and 14 percent advantages of the 75: 25 soybean and sweet basil and borage ratio and50: 50 soybean and borage compared to monoculture, respectively.
