  This research was done in order to evaluate the direct culture methods of rise under different humidity conditions at 2011-2012 in Sangar, Rasht. Thus, a split plot experiment was conducted as base of randomized completely block design in 4 replication. The experimental factors in 2 levels included: I1: water height permanently 2 cm above (full irrigation) and I2: just damp (low irrigation) and direct culture methods in 4 levels included: S1: pile culture, S2: linear culture, S3: broadcast culture and S4: control (transplanting) were considered. Results revealed that effect of irrigation and culture method and their interaction were significant on grain yield. The full irrigation with mean of 3098 kg/ha had the highest grain yield compare with low irrigation with mean of 1871 kg/ha. Results also indicated that pile culture with mean of 2594 kg/ha had the most grain yield and then transplanting method with mean of 2530 kg/ha was in a next ranking and finally broadcasting method with mean of 2349 kg/ha had the least grain yield. The interaction of treatments demonstrated that transplanting method with mean of 3314 kg/ha had the most grain yield under full irrigation condition. But the pile culture with mean of 2054 kg/ha under low irrigation condition was superior to other treatments. Manuscript profile

  In order to investigate the effect of nitrogen fertilizer and zinc sulfate sources on Calendulaofficinalis  plant yield, a factorial experiment was conducted in a randomized complete block design with three replications at 2011. Experimental factors included nitrogen fertilizer sources (manure and urea fertilizer) with 4 levels, 0 tons of manure + 120 kg urea, 10 tons of manure + 90 kg urea, 20 tons of manure + 60 kg urea, 30 tons of manure + 30 kg urea and 40 tons of manure + 0 kg urea and zinc sulfate with 3 levels, no foliar application, 1 foliar application and 2 foliar application times were recommended. Results showed that different sources of urea fertilizer were applied on capitol diameter. Number of seeds per plant and flower harvest index had a significant effect, but no significant effect on grain harvest index. The plant represents a significant effect on harvest index and harvest index put Dada, but had no significant effect also results indicated that the interaction between different sources of nitrogen and sulfate on the number of seeds per plant were significant.

  An experiment was conducted to investigate the effect of application of different nitrogen and biofertilizer systems on yield and yield components of sunflower seed in a split plot in a randomized complete block design with three replications. Nitrogen levels as the main factor in five levels including: N1: 100% nitrogen treatment (326 kg / ha urea), N2: 80% nitrogen (260 kg / ha urea), N3: 60% nitrogen (195 kg) Urea), N4: 80% N and 20% of manure (1.3 ton / ha) and N5: 60% N and 40% of manure (2.6 ton / ha) and application of azospirillum Sub-factor titles were considered at four levels: B1: non-application of azospirillum B2: inoculation with azospirillum, B3: foliar solution of azospirillum, B4: inoculation with fungal solution of azospirillum. The results showed that nitrogen fertilizer and azospirillum treatments had significant effect on the studied traits. So that treatment with 100% urea nitrogen source had the highest number of grains per head. Inoculation treatment with foliar application of azospirillium had the highest number of seeds per head. The results also showed that treatment with 100% urea nitrogen and 60% urea nitrogen fertilizer and 40% manure had the highest grain yield. Foliar treatments as well as seed inoculation + azospirillum had the highest grain yield, which were in the same statistical group. Manuscript profile

  AbstractDetection of medicinal plants growth under different irrigation conditions and drought stress can be a guide to planting resistant plants in arid or low water areas. In order to evaluate the effect of manure and mycorrhizal fungi on physiological indices of growth of naked seed pumpkin seedlings (cucurbita pepo L.) in underwater stress conditions, a split factorial in randomized complete block design with four replications in spring and summer 2009 The research center of Faizabad, Qazvin Agricultural and Natural Resources Research Center, was conducted. Irrigation at three levels including: I1 = 60, I2 = 120 and I3 = 180 (millimeter evaporation from a class A evaporation pan) in the main plots that were applied in the pre-flowering stage and the manure factor was at three levels: 0, 15 and 30 ton/ha, along with mycorrhizal fungi in two levels (application and non-application) in subplots. The results of four sampling stages showed that application of 30 tons per hectare of manure and application of mycorrhiza in dry matter conditions increased dry matter, relative growth rate and growth rate of crop. Also, after applying stress, physiological indices decreased. Manuscript profile
