This study was conducted to evaluate the impacts of nutrient elements on phytochemistry characters and qualities of strawberry in soilless culture system. The experiment was carried out in a factorial experiment based on randomized complete design with three replications. Treatments consisted of 6 groups of strawberry growing on soilless medium made of perlite and coco peat that were treated with different ratio of nutrient solutions. According to the results modified nutrient improved fruit nutritional characters but it was not unique. TSSS, TA, vitamin C and pH often were increased by increasing nutritional elements but anthocyanin was decreased by increasing some nutritional elements.

Rose and Lilium are the most important and marketable cut flowers in the world. However, a relatively limited vase life reduces its marketability. This study was performed to evaluate the effect of interaction of packaging flowers together in a preservative solution under exogenous ethylene and anti-ethylene treatments on their post harvest characteristics. The experiment consisted of pre-treating the flowers with silver thiosulfate 0.5 mM STS for 2 h at room temperature placed in pulsing solutions containing 8-hydroxyquinoline sulphate (8HQS) and packed (two packaging type, glass and polyethyleneamid) under exogenous ethylene treatment at 0.1, 10 and 100 μl l-1. Treatments were arranged in a completely randomized design with three replications. The results showed protein content, ethylene production and also fresh and dry weight rose and lilium (phythochemical charters affect on the flowers vase life) were changed significantly. Therefore based on the experiment results packaging type and concentration of exogenous ethylene treatment indicated the most important factors influencing on vase life. © 2015, National Centre for Agrarian Sciences.

This study was carried out to assess the land suitability for rainfed faba bean (Vicia faba L.) cultivation in Gonbad-Kavous region (Golestan province, north of Iran) using geographic information system (GIS) and analytical hierarchy process (AHP), the most common methods for evaluation of land use suitability. Several parameters were considered in this study, including the annual average, minimum and maximum temperatures, annual precipitation, slope, elevation, and some soil properties such as organic matter, pH, EC, texture, phosphorus, potassium, calcium, iron, and zinc. The environmental parameters and the classification system used in the this work are inspired by the United Nations Food and Agriculture Organization (FAO) method dedicated to land suitability. In determining the weights of parameters, expert opinions were consulted and the final land suitability map was generated in five classes. As evidenced by the results, it was estimated that 23.48% of the study area (48,354.5 ha) is highly suitable for faba bean cropping, while 25.38% (52,237.37 ha) is moderately suitable and 25.03% (51,522.85 ha) is marginally suitable. In addition, our results indicated that just 26.11% of total agricultural lands are non-suitable for crop production. The currently non-suitable (49,778.80 ha) and permanently non-suitable (3997.09 ha) classes are located in the north and northwest parts of Gonbad-Kavous township. Soil salinity, low organic matter, low precipitation, high Ca content, and deficiency of P and Fe contents were found to be key limiting factors in this area. © 2015 Elsevier Ltd.
