Objective: The effect of the combined use of nitrogen fertilizer with sugarcane residue compost and growth-promoting bacteria on wheat quality traits and yield in the heat stress conditions of the end of the season in Ahvaz was investigated.Methods: An experiment was carried out in the form of two split plots in the form of a randomized complete block design with three replications. The experimental factors include three sowing dates: 22 November, 11 December and 31 December in main plots; six combined of nitrogen with compost include control, 100% nitrogen, 75% nitrogen+ 25% compost, 50% nitrogen+ 50% compost, 25% nitrogen+ 75% compost and 100% compost in sub-plots and two levels of use and non-use of bacteria in sub plots.Results: Results showed the effect of Sowing date and the combined use of nitrogen with compost and growth-promoting bacteria were significant on all measured traits. Average comparison showed that combined use of 50% nitrogen + 50% compost with bacterial application increased the characteristics of Grain filling duration and Grain filling rate, Grain protein percentage and wet gluten. Also, the highest seed yield (5864 kg/ha) was obtained on the first planting date and combined consumption of 50% nitrogen + 50% compost and the lowest amount (1115 kg/ha) was obtained on the third planting date and the control treatment.Conclusion: The combined use of nitrogen fertilizer and compost with growth-promoting bacteria could reduce the negative effect of heat stress at the end of the season on the measured plant traits.

In order to evaluate the effect of salicylic acid and mycorrhizal in reducing salinity damage on the quantitative and qualitative yield of marigold a factorial pot experiment was conducted based on completely randomized design . This experiment was carried out with four replications in the Poldokhtar Payam Noor University in 2015. Experimental factors including salinity in 5 levels (Poldokhtar drinking water with electrical conductivity of 0.7 dS.m-1 is control), 2, 4, 6 and 8 dS.m-1, 4 levels of salicylic acid 0, 0.3, 0.6, and 0.9 mM and mycorrhiza was inoculated and no inoculated. The results showed that salinity reduced all the measured traits but only increased the antioxidant property. Consumption of Salicylic acid and mycorrhiza improved all the traits in salinity . The highest amount of chlorophyll a and b were in 0.7 dS-1 salinity and application of 0.6 mM salicylic acid with 0.115 and 0.207 mg.kg-1 fw, respectively which was significant with other treatments in 5%. Petal carotenoid was in 0.7 dS-1 salinity and application of 0.9 mM salicylic acid with 7.71 mg.kg-1 fw which was 15% higher than the same salinity and without using salicylic acid. The maximum of fresh weight of inflorescence content as economical yield with 12.56 gr.pot-1 was observed at 0.7 dS-1 salinity, 0.9 mM salicylic acid and mycorrhizal inoculation. Mycorrhiza increased 28 percent antioxidant properties and 21 percent colonization compared to the control treatment. Mycorrhiza by absorbing more water and nutrients in salinity improve the growing conditions of the plant and increase the yield.

To investigate the effect of different levels of vermicompost and boron on safflower grain and oil yield, a factorial experiment is conducted in a randomized complete block design with four replications in the 2016-17 crop year at the research farm of Agricultural Sciences and Natural Resources University of Khuzestan. Experimental factors include four levels of vermicompost (0, 4, 8, and 12 tons per hectare) and four boron levels (0, 3, 6, and 9 kg per hectare) from the source of boric acid (H3BO3) as soil application. The results show that the effect of vermicompost on most of the measured traits has been significant. Accordingly, biological yield and yield components including number of capitols per square meter, grain per capitol, and 1000-grain weight have increased significantly to the highest level of vermicompost consumption. The effect of boron on grain number per capitol, grain yield, biological yield, stigma yield, harvest index, oil yield, and grain protein percentage is significant. The interaction effect of vermicompost and boron on grain yield, harvest index, oil yield, grain protein percentage, and nitrogen uptake per unit aera is significant. Comparison of means show that the highest grain yield (3184 kg/ha) and the highest oil yield (939 kh/ha) are obtained in the treatment of 12 tons of vermiompost and 3 kg of boron per hectare. In both cases, grain and oil yield per unit area show a 100% increase, compared to the control treatment.

In order to determine drought stress in the final stages of flowering up to 50% pods and pods until harvest tolerance in canola genotypes via yield-base stress tolerance indices, a split plot experiment has been conducted based on the randomized complete block design with three replications at the research farm of department of plant production and genetics, Agricultural Sciences and Natural Resources University of Khuzestan, Iran during 2020-2021. The main plots include three irrigation treatments: the control (without any interruption of irrigation), interruption of irrigation in the beginning of flowering stage (phenology code 60) to the formation of 50% pods (phenology code 75), and interruption of irrigation in the stage of formation of pods until harvest (Phenology code 99) in the main plots. Also, the genotypes (Long pod, Aram, RGS 003, Jankom, Solar, Hayola 4815, Mahtab, Julius, Agamax, and Sala) are arranged in sub-plots with respect to irrigation treatments. They are reliable indices to identify drought tolerant rapeseed cultivars. Indices MP, GMP, and STI are the most suitable ones to evaluate drought stress tolerance in different treatments. The highest grain yield of control treatment belongs to Hayola 4815, Long pod, Solar genotypes (2093.8, 1791 and 1700 kg / ha), and the lowest to Jankum genotype (832.1 kg / ha), in flowering Stress up to 50% pods. The highest grain yield is observed in Hayola 4815 (1563.9 kg / ha) and Lon gpod (1150.9 kg / ha) and the lowest grain yield in Jankum and Mahtab genotype (540, 935.5 kg / ha).

In order to investigate the effect of Piriformospora indica and different levels of salicylic acid on morphological characteristics and activity of antioxidant enzymes of thyme (Thymus vulgaris L.) irrigation cut-off stress, an experiment has been conducted in the water year 2016. It has employed a split factorial experiment based on randomized complete block design with four replications in the research farm of Dehloran Agricultural Research Center. The treatments are consisted of four levels of salicylic acid (0, 150, 300, and 600 μm) as foliar application and a mycorrhiza fungus agent at two levels of inoculation and non-inoculation and irrigation cut-off stress at three levels (irrigation at 90%, 50%, and 30% filed capacity). The results of this study show that with increasing irrigation cut-off stress up to 30% filed capacity plant height, total weight of shoot, number of leaves, colonization percentage, and the enzymes Catalase and Peroxidase have decreased. Inoculation and treatment with salicylic acid up to a concentration of 300 μM could significantly reduce the destructive effects of irrigation cut-off stress on these traits. However, increasing the concentration of salicylic acid to the level of 600 μM intensifies the effects of irrigation cut-off stress, preventing the positive effects of the fungus.

In order to investigate the physiological responses of chickpea cultivars to supplemental irrigation and super-absorbent polymer use, an experiment was conducted in 2015 using a split factorial experiment based on randomized complete block design in the research farm of Khorramabad Agricultural Research Center. Factors were supplemental irrigation times (without supplemental irrigation, irrigation in 50 percent of flowering and irrigation in 50 percent of seed filling) as main factor and cultivars (Arman, Azad and Greet) and super absorbent polymer (zero, 100 and 200 kg/ha) in the sub plots. The result showed that the supplemental irrigation and super absorbent polymer reduced soluble carbohydrates and seed protein and increased insoluble carbohydrates, chlorophyll a, chlorophyll b and total chlorophyll. Supplemental irrigation in 50 percent of flowering satge increased 74 percent of seed yield compared to dry land condition. The highest seed yield, biological yield and harvest index were obtained from Greet cultivar with supplemental irrigation at 50 percent of flowering stage and application of 200 kg/ha super absorbent polymer, with the averages 2179 kg/ha, 4012 kg/ha and 54.3 percent, respectively. The results showed that at all levels of supplemental irrigation, the use of superabsorbent polymer improves plant growth conditions and, consequently, significantly increased seed yield. This will increase further by increasing the consumption of super absorbent polymer within supplementary irrigation.

In order to study the effect of the usage of vermicompost and mycorrhiza fertilizer usage on yield quantity and quality of soybean cultivar L17 in water deficit stress condition, an experiment was conducted as plots in a split at randomized complete blocks with four replications in Agricultural Research Center in 2013 in Khoramabad. The experiment treatments including irrigation in three levels (after 60, 120 and 180 mm evaporation from pan class A pan), vermicompost and mycorrhiza in six levels (non-use of vermicompost and mycorhiza fertilizer, inoculated with mycorrhiza fertilizer, consumption of 5 and 10 t.ha-1 vermicompost , consumption of 5 and 10 t.ha-1 vermicompost with mycorrhiza) were respectively as the main plots and sub. The results of experiment showed that the water deficit stress significantly decreased the number of pods per plant, number of grain per pod, number of grain per plant, 1000 grain weight, biological and grain yield. So that the highest grain yield with the rate of 3216.7 kg.ha-1 was obtained from 60 mm evaporation. The use of combined vermicompost and mycorrhiza fertilizer increased the traits except the number of grain per pods. Grain yield in combined treatment of 5 and 10 t.ha-1 vermicompost and mycorrhiza, respectively increased 23 and 29 percent compared to control. By increasing irrigation distance grain oil content decreased and grain protein content increased. Finally, in order to water_saving irrigation and the cost of inputs and ensuring optimal performance in drought condition, we can use combination of 5 t.ha-1 vermicompost with mycorrhiza.

To investigate wheat and wild mustard growth and competition to N levels, an experiment was conducted in Ramin Agriculture and Natural Resources University of Khouzestan, located at 36 km North of Ahvaz. Treatments included planting wheat solely, wild mustard solely, and intercropping wheat and wild mustard in pots. These combinations were exposed to N levels including 0, 60, 120 and 180 kg.ha-1. The results showed that grain yield, dry matter and spike number of wheat increased by increased N levels in sole crop treatment. These traits decreased by N levels when competing against wild mustard. Wheat grain and total protein content increased up to 120 kg N.ha-1 by increased N levels, but decreased while competing against wild mustard. The highest N apparent recovery by wheat was obtained from sole cropping of this crop and 120 kg N.ha-1. The lowest rate of this parameter was observed in competition condition against wild mustard and the level of 180 kg N.ha-1. The results showed that wild mustard traits had positive response to increased N levels, regardless to competition against wheat.

Filter mud is a residual of sugar extraction process produced in huge volume and has high organic matter and essential elements. Regarding to these properties, it seems this material could be a useful fertilizer in crop production. To evaluate effect of sugarcane filter muds and chemical and biological fertilizers application on canola (Brassica napus L.) yield and some of soil properties, a factorial experiment was conducted in 2012 in experimental farm of Ramin (Mollasani) Agriculture and Natural Resources University of Khouzestan. A complete block design was used for the experiment in three replications. Different integrated treatments of filter muds and chemical fertilizers including A1: 100 percent filter muds, A2: 75 percent filter muds and 25 percent chemical fertilizers, A3: 50 percent filter muds and 50 precent chemical fertilizers, A4: 25 percent filter muds and 75 percent chemical fertilizers and A5: 100 percent chemical fertilizers were investigated as an experimental factor. Other experimental factor was biological fertilizers application (with and without biological fertilizers). The biological fertilizers investigated in this study were included nitroxin and Barvar 2. Application of filter muds had significant effects on canola yield, yield components, grain oil and protein contents. The soil organic matter and salinity also were affected by filter muds significantly. Highest canola grain yield was obtained by integration of filter muds and chemical fertilizers. Increase of filter muds caused to increase of grain oil content and decrease of nitrogen and nitrate content. On the other hand, increase of chemical fertilizers increased nitrate and nitrogen contents and decreased oil content. In addition, increase of filter muds resulted in higher soil organic matter and salinity, simultaneously.
