To investigate the effects of nutrition systems on the yield and some traits of Mentha piperita L., this experiment was carried out in the experimental field of Kerman Agricultural and Natural Resources Research Center, during 2008 to 2010. A combined analysis of variance was performed using Randomized Complete Block Design with three replications by MSTATC statistical software and means were compared by Duncan test. The treatments were consisting of different levels of N, P and K (conventional system), mixture of different levels of NPK and manure (integrated system), different levels of manure (organic system) and control. The results showed that, the effect of nutrition systems on biological yield, economic yield, dry matter percentage, leaf length, leaf width, and plant height were significant. The yield increased with increasing the amount of nitrogen, phosphorus, and potassium. The yield of Mentha piperita in the integrated system was higher than that of other systems. Maximum fresh weight yield (38313 kg/ha) and maximum economic yield (5634 kg/ha ) were obtained in the first year from integrated system (120kg N, 90kg P, and 120kg K+5 tons manure per hectar). With increasing age of the plant, the fresh weight yield decreased to 15% and 63% in the second and third years, respectively. In the present experiment, the highest yield was obtained with application of 120 kg nitrogen, 90 kg phosphorus, 120 kg potassium, and 5 tons manure per hectare. The use of this plant in a plot of land more than three years will not be cost-effective.

Aloe vera L. is considered as one of the most important medicinal species, having high resistance to water scarcity and soil salinity. To investigate the effects of planting date and location on yield and a few characteristics of Aloe vera, a split plot experiment in a randomized complete blocks design was conducted with three replications in 2009. The main treatment included location at two levels (Tekab, 329 m a.s.l and Chahar Farsakh, 930 m a.s.l) and two planting dates including (October 2009 and February 2009) were considered as sub treatments. Data were analyzed in terms of yield per plant, height, leaf length, leaf width, and gel yield. According to the results, the highest yield, plant survival, gel yield and leaf number were obtained from the second planting date (25 Feb.). Also, a significant and positive correlation was found among the studied traits, as leaf number, leaf diameter, and plant height had the highest correlation with flower yield. According to the obtained results, the best planting location and planting date were Tekab (Shahdad) and 25 February, respectively.

This research was conducted for identification of essential oil of Labiatae spesies and investigation of ecological characteristics of their habitates in Kerman province.The Labiatae is very important in production of essential oil. Ecological characteristics are required for cultivation of natural and self growing plants of this family. Kerman province is about 186423 km3 in area and placed in southeast of Iran. Lowest and highest altitude in this province is 300m to 4500m a.s.l. and more than 10 kinds of climates are found in this area. 51 essential oil species belong to 17 genera. They are collected and identified by Flora. Many ecological characteristics of habitat are recorded as soil texture, rainfall, temperature, altitude, life form. More species belong to Nepeta and Salvia genera; chamaephyte and terophyte life formes; semiarid-cold, semiarid-warm and arid desert-cold; 2000-3000 altitude. Ziziphora tenuir L., Teucrium polium L., Nepeta glomerulosa Boiss. and Mentha longifolia (L.) Hudson are the most dispersed species in variety of climates, that indicates more ecological compitability of these species in different habitats.

This study was conducted at Research Center of Agriculture and Natural Resources of Kerman province in 2004-2006. Nine Damask rose accessions collected from different parts of Kerman province were planted using a three replicated randomized complete block design (RCB). Flower yield, flower number, single flower fresh and dry weight, flower dry matter percentage, petal/flower weight, petal, stamen and pistil numbers were evaluated. Results of ANOVA showed significant differences among accessions for all the traits. Also, significant correlation was observed between different traits, and flower yield showed maximum correlation with flower number and single flower weight. Comparison of means (Duncan method) classified the accessions into different groups based on the above characteristics. The accession collected from Rafsanjan showed the highest flower yield.

In order to investigate sowing date and cultivar effect a split –plot design was arranged in randomized complete block with four replication carried out in natural resources research station of kerman research center. Main plots were included four sowing dates (15Mar and 30Mar and 14Apr and 29Apr) and sub plots were included three cultivars (Cv.kerman, arak 2811,Esfahan native). From planting to total growth stages the following parameters (seedling, stems, bottom, flowering, and maturation) were effected with plant date and were reduced with delay in planting. Effect of plant date on plant height, sub branch number, heads per plant, seed weight, dry weigh of plant, seed yield and flowering, oil, and protein yield was significant and all of them reduced with delay in plant. Seed protein percent was increased with delay in planting and also seed oil increased with acceleration in early planting. The results showed that interaction between plant date and cultivar on plant height, sub branch number, heads per plant, seed number per heads, seed weight, biological yield, seed yield, oil yield, protein yield, percent of protein and oil was significant but in harvest index wasn’t significant. The second plant date 30March and CV.kerman are suitable for seed yield and Esfahan native cultivar is suitable for seed oil and recommend for planting and producing in Kerman climate condition.
