Abstract
Construction and function of active substances of medicinal plants is influenced by environmental factors such as deficiency or increasing of nutrients in the soil and substrates type. Thus, an experiment was carried out in factorial experiment in the base of randomized complete with 16 treatments and 3 replications . The aim of this research was Influence of vermicompost and nano potassium fertilizer on morphological and phytochemical characteristics in Aloe vera . The treatments were four levels of vermicompost (0,15, 30 and 45), in the Volume percents with soil of culture and Nano potassium in 3 levels 2, 4, 6 gr/l and 0 as control. The results showed that the maximum amount of gel weight, gel moisture content, gel glucomannan and anthocyanin of cortex was obtained in 30% of vermicompost and 4 g/l of nano potassium. The interaction of these two factors was increased the gel antioxidant capacity and moisture content and showed maximum amount in 30% vermicompost and 2g/l nano potassium. The maximum of weight leaf was belonged in 30% of vermicompost and 6g/l nano potassium and maximum amount of gel flavonoid showed in 15 % of vermicompost and 4g/l nano potassium. Thus, using of combination substrateand of vermicompost ana foliar application of nano potassium fertilizer in aloe vera cultivation. has an effective role in the production leaves and gel high quality and the way influence it depending on characteristics is function of combination vermicompost substrate and nano-potassium fertilizer concentration.

Abstract
With respect to the fact that the pH of the food solution has a great role in the absorption of iron element. An experiment was conducted twice plate (split plot of split plot) in the from of randomized complete block design on a strawberry plant of diamante cultivar at the researcher station of Ardebili Mohaghegh Ardabili University during the years 2015- 17. Factors included acetic acid (0, 1, 2 and %3), iron at two levels (sequestrin25gr and nano 1gr) along with two levels of agricultural soap agents (0 and % 7/5) as foliar spraying. Plant growth indices including protein, proline, resuscitation sugars, leaf starch, total phenol, leaf iron content, and yield per plant were measured. The results of analysis of variance showed that the three-way effect of treatments in all studied traits except protein and yield at the level of %1proabability on proline, resuscitation sugars, leaf starch, total phenol, leaf iron content was significant, such that the best result in the adjectives obtained from the combination of %2 steak acetic acid with iron, along with the application of %7/5 of Mooyan farming soap. and the mutual interaction of treatments at the probability level of %5 on the proten and the performance had a significant effect that which was the best results related to the combination of %2 of acetic acid with iron fertilizer without the use of Mooyan farming soap. According to the results of this study, the combination of %2 iron acetic acid composition with iron acid, along with %7/5 of the farming soap due to the reduction of leaf area tensions, improves the absorption of iron and increases the biochemical and morphological characteristics of straw berries cv.Diamant.
