Abstract
In order to evaluation of intercropping of forage sorghum (Sorghum bicolor) and vetch (Vicia villosa) in different nitrogen fertilizer levels and different planting patterns, a field experiment was conducted at the Agricultural Research Station, University of Maragheh in 2013 growing season. Experimental design was factorial based on randomized complete block design (RCBD) with three replications. The treatments were nitrogen fertilizer levels (0, 30 and 60 kg N. ha-1) and three planting patterns [(Planting sorghum on the furrow bank and planting vetch in the both side of furrow bank (P1), Planting sorghum in one side of furrow bank and planting vetch in other side (P2) and Planting sorghum on the furrow bank and planting vetch on the furrow bank and both side of furrow bank (P3)]. Results indicated that nitrogen fertilizer application increased sorghum dry matter yield and first planting pattern (P1) had highest sorghum yield among intercropping treatments. The highest forage yield (371.7 kg. ha-1) of vetch produced in the third nitrogen fertilizer level (N60) and third planting pattern (P3). In all intercropping treatments, land equivalent ratios (LER) were well above 1 indicating yield advantages for intercropping. The greater LER of the intercrops was mainly due to a greater resource use and resource complementarities that when the species were grown alone. The highest LER (1.94) and RVT (1.14) were obtained in first planting pattern with no nitrogen application. Also the greatest LERs (1.92) were obtained under interaction of second planting pattern and third nitrogen fertilizer level (N60). In general, it can be stated that for the production of forage, the combination of first planting pattern with no nitrogen application is superior on other planting patterns.

Abstract
In order to evaluate seed yield and its components in fall oilseed rape genotypes under water deficit stress during flowering and seed filling stages, a field experiment was conducted as split plot based on a randomized complete block design with three replications in East Azerbaijan Research Center for Agriculture and Natural Resources during growing season of 2012-2013. The experimental factors were irrigation with three levels including: non-stressed and drought stress during flowering and seed filling stages (reducing the irrigation for one time in comparison with control treatment) and 18 fall oilseed rape genotypes. The results indicated that water deficit significantly decreased plant height. Occurring drought at flowering stage, led to significant decrease in pod length, number of pods per plant and seed yield. Water deficit stress during flowering decreased seed yield via aborting of pods. Among studied genotypes, significant differences were seen in number of pods per plant and Karaj2, HW101, L72, L183, HW113, Karaj3 and L210 indicated more amounts of pods number of per plant. There are significant and positive correlations among seed yield with number of pods per plant, plant height and pod length, that they showed the importance of these traits in supporting of seed yield. The cluster analysis divided genotypes into 3 categories based on the studied traits. One group consist of L73, L183, L72 and HW101 genotypes in comparison with 2 other groups, indicated the higher amounts of pods per plant and seed yield. These genotypes were more suitable to cultivation in water deficit and normal conditions than others.

To evaluate effect of different irrigation regimes and mycorrhizal fungi on the growth and grain yield of mungbean (Vigna radiata (L.), a pod experiment was conducted in factorial arrangement based on completely randomized design with three replications at Urmia university in 2009. Treatments were irrigations (after 25, 50, 75 and 100 mm evaporation from class A pan) and mycorrhiza (Glomus mosseae, G. intraradices and a non-inoculated treatment as a control). Results showed that total dry weight, leaf dry weight, leaf area increased by diminuting of irrigation intervals. So, the highest (5.14 g/plant) and lowest (1.97 g/plant) grain yield were observed at 25 and 100 mm evaporation from class A pan, respectively. But, application of fertilizer sources to compensate the undesirable effects of drought stress, so the maximum grain yield (63 %) was obtained from mycorrhizal mungbean plants compared with non mycorrhizal plants due to the highest total dry weight, leaf dry weight and leaf area in symbiosis conditions. Water deficit stress caused to decrease pods/plant (49.82%), grains/plant (20.26%) and grains/pod (60.43%). Mycorrhizal fungi species enhanced grain yeild of mungbean through their effects on pods/plant, grains/plant and grains/pod. In conclusion, these results showed that the mycorrhizal inoculation have compensated the water deficit induced yield (49.61%) losses.

Abstract
In order to determine drought stress × different levels of fertilizer sources (Chemical, animal manure, and integrated) interactions on purslane production, a field experiment was conducted in split plot design with three replications at the agricultural research farm of Shahrekord University in 2012. Main plots consisted of normal irrigation and drought stress as the water holding one month after planting for 12 days and subplots were consisted control (no fertilizer and manure), two levels of Urea (30 and 90 kg/ N ha), two levels of Animal manure (30 and 90 90 kg/ N ha) and three levels of integrated application (60 90 kg/ N ha ratio 2:1, 1:1 and 1:2 of resources Urea and Animal manure). The results showed that in the first cutting and sum of two cutting, stem dry weight and aboveground dry weight influenced by drought stress, but effect of drought stress was not significant on leaf dry weight in both cutting and stem dry weight in second cutting. Overall, increasing N fertilizer application increased the weight of the plants parts. In each cutting, the highest leaf, stem and aboveground dry weight were obtained at 90 kg/ N ha in the form of manure, and treatment 90 kg/ N ha in the from urea has not a significant difference with 60 kg/ N ha from cow manure plus urea fertilizer (1:1). According to the results experiment can be stated that the individual application of manure, and combined application with manure with N fertilizer have exhibited high efficiency but the application of different levels of fertilizer sources was not diminish the effects of drought stress in this crop production.

Salinity of soil and irrigation water is one of the major concern for crop production under salt-affected arid and semi-arid areas of the world. Using beneficial plant growth promoting microorganisms such as plant symbiotic fungi and plant growth promoting bacteria can be an implement in alleviating deleterious effect of salinity. In this regards, a greenhouse experiment was conducted out in 2012 to investigate the effects of salinity irrigation (low, mild, high and severe) and Piriformospora indica inoculationon grain yield and some physiological traits of wheat under interference with wild oat weed (Avena ludoviciana L.). Experimental disgn was factorial arranged in randomized complete block with three replications. P. indica increased grain yield of wheat under both non-salinity and salinity conditions. Wheat plants in sole culture and in interference with wild oat weed had higher grain P content, proline accumulation and chlorophyll content of leaf. In conclusion, P. indica sustained or improve grain yield of salt-stressed wheat under competition with wild oat through improvement of P uptake, proline accomulation and chlorophyll content. Result of this study showed that inoculation seed of wheat with P. indica may be considered as a new method to manage crop-weed interference under salt-affected areas.

Abstract
In order to assessment the weed biomass, yield and yield components of maize under presence of soybean, bean and clover as cover crops an experiment was performed in randomized complete block design with 8 treatments and 3 replications in Sari agricultural sciences and natural resources university in 2011. Treatments were included the planting of cover crops at the same date and 21 days after planting with maize and sole cropping of maize under weed control and weed infestation. The results showed that soybean in first and second planting date reduced the weed biomass 98.96 and 98.36%, and bean in first and second planting date reduced the weed biomass 97.56 and 97.59% compared to sole cropping of maize under weed interference, respectively. Whereas, the clover in both planting date were less success in weed control. Moreover, the maximum of rows in ear, seed in ear row of maize was observed in sole cropping of maize under weed control and there was no significant difference between sole cropping of maize under weed control and first and second planting date of soybean and second planting date of bean. Except of first planting date of clover and sole cropping of maize under weed infestation, differences in thousand kernel weight of maize were not significant in other treatments. Maximum maize yield (10741 Kg/ha) was achieved in sole cropping of maize under weed control, which was not significantly different with first and second planting date of soybean. In cover crop treatments, the lowest yield and yield components of maize was recorded in clover treatments. In general, soybean reduced the weed biomass and the seed yield of maize under presence of soybean was higher than other cover crops.
