Calcium is one of the most important minerals involved in determining the quality of the fruit. Excessive waste and quality loss of seedless barberry (Berberis vulgaris L.) during harvesting, post-harvest, and storage are some of the important problems in production areas. Foliar application with minerals can increase the quality, yield, marketability, and reduce post-harvest losses through the provision of plant nutritional needs. Therefore, in this study, the effect of foliar application of calcium chloride and calcium nitrate on the quantitative and qualitative characteristics of barberry fruit was carried out in a randomized complete block design. Treatments included control (distilled water), calcium chloride (0.5%), and calcium nitrate (0.5%). The foliar spray was performed in four stages of the growing season. The results showed that the highest mean number of panicles per branch, the number of berries per panicle, the number of berries per branch, and the fruit yield on the branches belonged to the calcium chloride treatment and the lowest amount in the control. The calcium chloride treatment increased the fresh weight diameter and length of branch compared to the control treatment. The highest amount of chlorophylls a and b and total chlorophyll was observed in the leaves of control trees. The effect of calcium chloride and calcium nitrate treatments on the appearance quality and texture of barberry fruit was significant, although it did not affect the chemical properties of the fruit. In general, the results showed that foliar application with calcium chloride and calcium nitrate salts improved the quantitative and qualitative characteristics of the fruit compared to control.

Saffron (Crocus sativus L.) is one of the most important and precious medicinal plants in the world. In order to investigate the effects of different of municipal waste vermicompost on vegetative and reproductive characteristics of leaf and corm of saffron, an experiment was conducted based on a randomized complete block design with three replications at the Agricultural Research Station, University of Birjand during the growing season of 2015. The treatments included four levels of municipal waste vermicompost (0, 5, 10 and 15 t.ha-1). Results showed that municipal waste vermicompost in the second year improved the reproductive characteristics so that the highest flower yield was obtained from 10 t.ha-1 municipal waste vermicompost (22.5g.m-2) and the highest dry stigma yield was obtained from 5 t.ha-1 municipal waste vermicompost (0.44g.m-2). The highest average leaf number (8.36), average fresh weight and dry weight of leaf (0.33 and 0.099 g, respectively) were obtained in plants treated with 15 t.ha-1 municipal waste vermicompost and the highest leaf length (249.3 mm) was obtained at 10 t.ha-1. Application of this organic fertilizer could have a significant effect on chlorophyll a and total chlorophyll content and SPAD. The highest photosynthetic pigments were obtained from application of 10 t.ha-1 municipal waste vermicompost. The characteristics of the corm including the number of cormel, fresh and dry weight of cormel and number of cormel buds were affected by municipal waste vermicompost treatment. The highest number of cormel was obtained from plants treated with 10 t.ha-1. Also results showed that treatment of 5 t.ha-1 of municipal waste vermicompost had the greatest effect on fresh and dry weight of cormel. This treatment improved the number of cormel (33/1) as compared with control (5). Thus, results showed that municipal waste vermicompost had strong impact on vegetative and reproductive characteristics of saffron.

The effects of applications of humic acid and planting density on quantitative and qualitative characteristics of saffron (Crocus sativus L.) were evaluated under field conditions. Treatments were of four levels of humic acid (0, 5, 10 and 15 Kg.ha-1) and three density planting (50, 75 and 100 corms.m-2). This experiment was carried out as factorial based on randomized complete block design with three replications in research farm of Birjand University, Iran, during growing season 2015. Flower fresh weight and fresh and dry weight of stigma were influenced by humic acid treatments. The highest flower fresh weight (0.36g.m-2) was obtained in plants treated with 5 kg.ha-1 humic acid while the lowest values were recorded in the control (0.33g.m-2). However, no significant difference was found in yield and flower number of saffron, length of stigma and style, fresh weight and dry weight of style under different levels of humic acid treatments. Results showed that humic acid improved the leaf growth indices (leaf length, fresh weight, and dry weight of leaf) and photosynthetic pigments (chl b, total chl and spad). The highest leaf length, fresh and dry weight of leaf, chl b, total chl and spad were obtained in plants treated with 10 kg.ha-1 humic acid while the lowest values were recorded in the control. Application of different levels of planting density had a positive effect on the yield and flower number, length of stigma, length of leaf, fresh and dry weight of leaf in saffron. The highest flower number (22.25per.m-2) and yield (8.22g.m-2) were observed in planting density of 100 corms.m-2. Interactive effects of humic acid and density had a positive effect on the flower yield, length and dry weight of stigma, fresh weight and length of leaf and chl b.
