Abstract
In order to investigate the possibility of reducing the quantitative and qualitative damage of rapeseed Neptune cultivar in water deficit tension conditions by applying foliar application of salicylic acid and micronutrients in Khorramabad climate, an experiment was conducted as a factorial split plot in a randomized complete blocks statistical design with three replications at Faculty of Agriculture Lorestan University in cropping year 2016-2017. Irrigation at two levels of 20 and 70 percent of field capacity depletion was applied in the main plots and composition of micronutrients (B1 non- consumption and B2 foliar application with a ratio of 2 per thousand) and salicylic acid factor (concentrations of zero, 0.5, 1 and 1.5 millimolar) were compared in sub-plots. The results showed that the simple effects of water deficit tension, foliar application of micronutrients fertilizer and salicylic acid on all tested traits were significant. Also, the triple interaction on number of pods per plant, seed yield, oil yield and carotenoids was significant. The highest seed yield and oil yield were obtained with an average of 4424.7 and 2036.7 kilogram per hectare in the optimal irrigation treatment and foliar application of micronutrients fertilizer with a concentration of 2 per thousand and salicylic acid with a concentration of 1.5 millimolar, respectively. Water deficit tension decreased total chlorophyll, carotenoid, number of stalks per plant, number of seeds per stalk, one-thousand seed weight, grain yield, oil percentage and oil yield by 14, 28, 20, 17, 27, 42, 42, 14 and 49 percent, respectively. However, foliar application of salicylic acid and micronutrients, while increasing resistance to water deficit tension conditions, could improve plant growth and physiological characteristics, including increasing photosynthetic pigments, provide favorable conditions for better plant growth and by increasing the grain yield components, finally increase the grain yield by 29 percent (1281.5 kilogram per hectare)in non tension conditions and 36 percent (1064.9 kilogram per hectare) in tension conditions. Therefore, a triple fertimix micronutrient fertilizer (iron + zinc + manganese) with a concentration of 2 per thousand is recommended along with a concentration of 1.5 millimolar of salicylic acid to reduce the negative effects of water deficit tension and achieving acceptable yield.

Abstract
Due to the importance of forage plants for livestock feed and low crop production, an experiment was conducted to evaluate the quantity and quality of Vicia narbonensis and Hordeum vulgar intercropping in rainfed conditions of Khorramabad under the influence of biofertilizer Aztobarvar-1 and superabsorbent in the form of rainfed at the research farm of Faculty of Agriculture of Lorestan University in 2017-2018 cropping year as a factorial based on a randomized complete blocks design with three replications. The first factor in 5 levels: 1- vetch monocropping (100 percent vetch) 2- barley monocropping (100 percent barley) 3- intercropping (vetch 25 percent: 75 percent barley) 4- intercropping (50 percent vetch: 50 percent barley) 5- intercropping (vetch 75 percent: 25 percent barley) by substitution method and the second factor in four levels 1-No use of Aztobarvar -1 and superabsorbent material (control) 2- Aztobarvar-1 (seed and foliar spraying) 3- Superabsorbent 4- Aztobarvar -1(seed and foliar spraying) + superabsorbent was considered. The results showed that the highest total dry forage yield and land equivalent ratio were obtained from the treatment (50 percent vetch: 50 percent barley), the highest protein percentage and crude forage protein yield, as well as leaf area index were obtained from vetch and barley monocropping in which by increasing the proportion of vetch in the composition, an increase in protein occurred in barley forage. In vetch plant, increasing plant density decreased the anti-nutritional traits of forage (insoluble fibers in neutral detergents) and vice versa in barley, these traits increased. The results showed that the contribution of vetch in coexistence with barley was effective in production, on the other hand, the combination of biofertilizer Aztobarvar-1 as a reliable alternative to nitrogen fertilizers and superabsorbent with the ability to store rainwater, especially at the end of the growing season; in addition to increasing the quantitative and qualitative yield of forage ;could play an important role in sustainable agriculture and healthy production as the best solution in rainfed and low rainfall areas.

Abstract
In order to investigate the effect of foliar application of salicylic acid and micronutrients on photosynthetic activities and grain yield of rapeseed under low water tension conditions, an experiment was conducted as a factorial split plot in the form of a statistical randomized complete blocks design with three replications in Agricultural University of Lorestan in the cropping year of 2016-2017. Irrigation at two levels of 20 and 70 percent of field capacity depletion in the main plots and the composition of micronutrients (B1 non-consumption and B2 foliar application at a ratio of 2 per thousand) and salicylic acid factor (concentrations of zero, 0.5, 1 and 1.5 milimolar) were studied in subplots. The results showed that the triple interaction on leaf area index, stomatal conductance, transpiration rate and grain yield were significant. The highest grain yield of 4424 kilogram per hectare was obtained under non-tension and foliar application of micronutrient fertilizer with a concentration of 1.5 milimolar salicylic acid. Water deficit tension affected plant leaf area index and plant gas exchange and by reducing physiological traits such as photosynthesis rate, stomatal conductance, mesophilic conductance, transpiration rate and increasing the concentration of carbon dioxide under the stomatal chamber finally reduced grain yield in canola; however, foliar application of salicylic acid and micronutrients, while significantly reducing the concentration of carbon dioxide under the stomatal chamber, significantly increased leaf area index, mesophilic conductance, stomatal conductance, transpiration rate and photosynthesis rate. Transpiration rate and photosynthesis rate to some extent reduced the negative effects of drought tension on physiological traits of rapeseed and increased grain yield by 37.79 percent. Therefore, Ferti triple mix micronutrient (iron + zinc + manganese) with a concentration of 2 per thousand along with a concentration of one and a half millimoles of salicylic acid is recommended to reduce the adverse effects of water deficit tension and achieve proper performance.

Abstract
In order to investigate the effect of planting date and cultivar on yield components and physiological traits, split plot was performed in a randomized complete block design with three replications in 2020-2021years at the University of Lorestan. The main factor consisted of four cultivation dates 6 October, 21 October, 5 November, 21 November and the sub-agent of the figure, including Chamran, Sirvan, Mihan. The results of analysis of variance showed that simple effect of planting date on all traits in one percentage probability level and simple effects of cultivar on grain yield, harvest index, number of spikes per square meter, 1000 grain weight and dry matter remobilization at the probability level of a Percent was significant. Planting date on 6 October due to early culture and developmental stages with lower temperatures of plant tolerance and planting date 21 November due to delay during planting and limiting the production of tillers per plant and, as a result of reducing the number of spikes per square meter, grain yield decreased. The highest grain yield with 6976 kg ha-1 was related to the planting date of 5 November and the Mihan cultivar. In general, the history of cultivation, while increasing the optimal conditions for wheat cultivars, provide growth and physiological characteristics of the plant, including photosynthetic components, provide favorable conditions for the more favorable growth of the plant and ultimately increase the event. In the recent study, the Date of Planting 5 November and Mihan cultivar is recommended as the best planting date and cultivar for Khorramabad region and similar climate areas.

Abstract
Forage plant often cultivated individually to feed livestock, which leads to a shortage of forage and seeds, especially in winter. In order to investigate the effects of biofertilizer Aztobarvar-1 and superabsorbent on some quantitative and qualitative traits of grain in vetch and barley intercropping in dryland conditions of Khorramabad, an experiment was conducted at the research farm of Lorestan University, Faculty of Agriculture, in the 2017-18 crop year as a factorial based on a randomized complete block design with three replications.The first factor was implemented in 5 levels including: 1- Pure cultivation of vetch (100% vetch) 2- Pure cultivation of barley (100% barley) 3- intercropping(25% vetch + 75% barley) 4- intercropping(50% vetch + 50% Barley 5- intercropping(75% vetch + 25% barley) by alternative method and the second factor was implemented in 4 levels including: 1- (control) 2- Azotobar-1 (seed and foliar spraying) 3- Superabsorbent 4- Azotobar-1 (Seed and foliar spraying) + superabsorbent. In this experiment, the highest quantitative and qualitative seed yield was obtained from the treatment (50% vetch + 50% barley), the highest number of pods in vetch and spike in barley (m2) was observed in pure cultivation.In addition, the highest thousand grain weight of vetch and barley was observed in 25% of the intercropping. So, it was concluded that the coexistence of vetch with barley was effective in increasing the quantity and quality of seeds.On the other hand, Aztobarvar-1 biofertilizer was more economical than nitrogen-containing chemical fertilizers.And also, this fertilizer was able to act as a safe alternative to nitrogenous chemical fertilizers with the lowest amount (100 g/ha). In addition, the combination of this fertilizer with superabsorbent material (absorber and storage of rainwater) increased the quantitative and qualitative yield in vetch and barley seeds.

Abstract
This study was conducted to investigate the effect of different irrigation regimes on forage quantity, water and energy productivity of two maize cultivars during the 2017-18 as experiment of split plots in block design with three replications in the northwest of Isfahan, Iran. The main plots and the sub-plots included three levels of irrigation (100%, 80 and 60% full irrigation) and two cultivars of maize (704 and Maxima).Results indicated that, water level and genotypes, had significant effect (p<0.01) on fresh and dry forage yield ,fresh and dry forage of water and energy productivity. The highest fresh forage yield and water and energy productivity observed in 100% irrigation level in cultivar 704 (69 t.ha-1, 10 kg.m-3 and 0.74 kg.mJ-1, respectively).While, the highest dry forage yield and water and energy productivity in same level found in Maxima cultivar (23 t.ha-1, 3.4 kg.m-3 and 0.25 kg.mj-1 in, respectively). The highest fresh forage yield and water and energy productivity observed in 100% irrigation level in 704 (69.2 t.ha-1, 10.4 kg.m-3 and 0.7 kg.mj-1). While, the highest dry forage yield and water and energy productivity at the same level were observed in Maxima (23.3 t.ha-1, 3.4 kg.m-3 and 0.25 kg.mj-1). In general, due to the selection of suitable cultivars in arid areas, Maxima are more suitable than 704. Although, the input energy of both cultivars is equal with respect to equal consumption inputs. However, due to environmental effects of consumption of inputs, Maxima is superior. Therefore, by choosing the appropriate forage cultivar, an important step can be taken in sustainable improvement and problem of water shortage in arid and semi-arid regions.

Abstract
Despite genetic advances, the emergence of limiting factors such as climate, soil and crop management has led to a significant gap in many areas between farmers harvest performance and genetic yield potential. Knowing the limiting factors and proper planning and determining strategies to increase the adaptation of crops to these possible changes, causes the appropriate response of crops to these changes. For this purpose, the present study was conducted to investigate the effect of planting date and cultivar on yield and experimental physiological traits as a split plot in the form of a randomized complete block design with three replications in the crop year 2020-2021 in the Faculty of Agriculture, Lorestan University. The main factor included the four planting dates of 6 October, 21 October, 5 November, 20 November and the secondary factor of the cultivar, which included Chamran 2, Sirvan and Mihan. The results of analysis of variance showed that the simple effect of planting date on all studied traits was significant at one percent probability level and the simple effects of cultivar on photosynthesis rate, grain yield at one percent probability level and mesophilic conductance, stomatal conductance at five percent probability level were significant. Planting date was 6 October due to early sowing and occurrence of growth stages with temperatures lower than plant tolerance and planting date was 20 November due to delay in sowing time reduced seed yield. In general, the appropriate planting date, while increasing the optimal conditions for wheat cultivars, the growth and physiological characteristics of the plant, including photosynthetic components, provide favorable conditions for better plant growth and ultimately increase grain yield. In this study, this planting date of 5 November and Mihan cultivar is recommended as the best planting date and cultivar for Khorramabad region and similar climatic regions, respectively.

Abstract
The research was conducted during the agricultural years 2019-2020 and 2020-2021 to investigate the impact of biological and chemical fertilizers on the quantitative and qualitative traits of two red bean varieties under different irrigation systems in the Aligudarz City of Lorestan Province. The experiment was designed as a factorial split-plot in a randomized complete block design with three replications. The experimental treatments included irrigation methods at two levels (Furrow and Drip) in main plots, the combination of varieties at two levels (Akhtar and Yaghout) and fertilizers at three levels (1- NPK, 2- combination of biological and chemical fertilizers and 3- pure nitrogen) in sub-plots. The results of the average comparison showed that the highest grain protein content was recorded in the Akhtar variety with the application of biological and chemical fertilizers and furrow irrigation in the first year. Additionally, The highest thousand grain weight was obtained in the Akhtar variety and the highest number of seeds in pods was obtained in Yaghout variety. The highest number of pods per plant, grain yield were obtained in the Yaghout variety with the application of biological and chemical fertilizers and drip irrigation in the first year. Based on the results of the two-year composite analysis of the data, the tripartite integration of the Yaghout variety, the combination of biological and chemical fertilizers and drip irrigation due to the highest percentage of seed protein (26.4%) and the seed yield (112.8%) compared to the Akhtar variety, NPK fertilizer and furrow irrigation were the best treatments in bean.
