        In order to study the effects of seeding rates on yield and yield components of three bread wheat cultivars, a factorial experiment based on randomized complete block design (RCBD) with 3 replications was conducted during 2006-2007, in Sarableh town, Ilam province, Iran More
        In order to study the effects of seeding rates on yield and yield components of three bread wheat cultivars, a factorial experiment based on randomized complete block design (RCBD) with 3 replications was conducted during 2006-2007, in Sarableh town, Ilam province, Iran. Three cultivars, were Chamran, Chanab, and Falat and four seeding rates were 200, 300, 400, and 500 seeds per m2. Results showed that, the differences among cultivars and seeding rates were significant for 1000 seeds weight, harvest index, and phenological traits, using 400 seeds per m2. Chamrans produced highest harvest index and Chanab at seeding rate of 200 seeds per m2 had the lowest harvest index. Falat produced the highest seed yield (5600 kg/ha) at 400 seeds per m2 and Chanab the lowest seed yield (3800 kg/ha) at 500 seeds per m2. The highest correlation coefficients were observed between seed yield, harvest index (r=0.84**), seed numbers per spike (r=0.79**) and 1000 seeds weight (r=0.59*). Manuscript profile

        In order to study the effects of biofertilizer and phosphate fertilizer on yield and yield components of spring wheat a factorial experiment based on randomized completed blocks design with replications was conducted at the Mohsenabad, Mehran Research station in Ilam, Iran during 2009-2010. Experimental factors consisted of phosphorus chemical fertilizers at four levels(0, 90, 135 and 180 kg ha-1) and bio-fertilizer at four levels (non-inoculation, inoculating with Azotobacter chroococcum, Pseudomonas Putida and Azotobacter plus Pseudomonas). Results of analysis variance showed that using chemical fertilizer significantly effected grain yield, harvest index, biological yield, plant height and protein content. The highest grain and biological yields were produced by applying180 kg ha-1, while its effects on other traits were not significantly different from that of 135 kg ha-1. Biological fertilizers, on the other hand increased grain yield, harvest index, biological yield, plant height and protein content as compared to non inoculation treatment. The highest grain yield, harvest index, biological yield, plant height and protein content obtained from application of Azotobacter plus Pseudomonas. Grain yield, harvest index, biological, plant height were affected by interaction effects of chemical fertilizer and biological fertilizers. The highest and lowest grain yield belonged to the application of 180 kg ha-1 of chemical fertilizer and Azotobacter plus Pseudomonas and non- chemical fertilizer and non-inoculation, respectively, but the difference between 135 and 180 kg.ha-1 was not statistically different. Thus, it is cheaper to recommend use of 135 kg ha-1 of chemical fertilizer and Azotobacter plus Pseudomonas to get acceptable grain and biological yields. Manuscript profile

        In order to study the effect of supplementary irrigation on yield, yield components and protein percentages of three cultivars of chickpea an experiment carried out as split plot, based on randomized complete blocks design, with three replications in Ilam, in 2009-2010 growing season. Irrigation treatments were: control, without irrigation (I0), irrigation at the stage of %50 blooming, irrigation at the stage of %50 flowering, irrigation at the stage of pods filling, which were allocated to main plots and genotypes, ILC482, Filip93-93 and local variety to sub plots. Irrigation treatments had significantly effect on seed and biological yields, harvest index, pod numbers per plant, seed numbers per pod and 100 seed weight. The Filip93-93 produced highest (1140.51 kg/ha) and the local variety lowest seed yields (1056.98 kg/ha).Irrigation at the stage of pod filling and blooming increased by seed yield %41.3 and %29.3 respectively as  compared to control .Irrigation at the pod filling period produced the highest seed yield. The Filip93-93 produced highest yield (1263.31 kg/ha) when the field irrigated at pod filling stage and the local variety at control treatment (without irrigation) the lowest seed yield (893.26 kg/ha).

        Biofertilizers are inputs that naturally supplement replace chemical fertilizers and they are recommended in sustainable agriculture. To study the effects of biological fertilizers on yield and yield components of corn, a factorial experiment in randomized complete block design with three replications were conducted at Dareh-shahr, Iran in 2010. Biological factors were 4 levels of nitrogen biofertilizers (nitroxin, nitrokara, supernitroplus and control) and 4 levels of phosphorus biofertilizers (biophosphore, phosphate fertilized 2, MC1 and control). Results showed that biological nitrogen and phosphorus fertilizers had significant effects on all traits under study. Interaction of nitrogen biological fertilizer × phosphate biological fertilizer was significant on 100 seed weight (P<0.01) and the number of grains per ear row (P<0.05). Applying super nitroplus increased seed yield up to 9125 kg/ha, which is 47% more than control. Use of biological phosphate fertilizer produced 36% more seed yield 9149 kg/ha compared with control treatment. Generally, the use of biological nitrogen and phosphorus fertilizers improves yield and yield components appreciably in corn. Manuscript profile

        In order to study the effects of different compounds of biofertilizer and Nitrogen on yield and yield components of three bread wheat varieties including Chamran, Pishtaz, and Bahar, an experiment was conducted at agricultural research station in Shirvanchardavol, Ilam More
        In order to study the effects of different compounds of biofertilizer and Nitrogen on yield and yield components of three bread wheat varieties including Chamran, Pishtaz, and Bahar, an experiment was conducted at agricultural research station in Shirvanchardavol, Ilam province, 2007-2008. This experiment was arranged as split-plot in RCBD (Randomized Completely Block Design) with four replications. Chamran, Pishtaz, and Bahar cultivars were allocated to main plots and the compounds of biological and chemical fertilizers were arranged in sub-plots. The results of the studied characteristics variance analysis showed that the weight of 1000 seeds and protein content were not significantly affected by the variety, but other characteristics were significantly affected by the variety and different levels of fertilizer compounds. The results indicated that the compounds of fertilizer and Azotobacter compared to the application of the one by itself result in a higher yield. In addition, by applying Azotobacter, the amount of the applied Nitrogen would be reduced, but in the course of this experiment, high yield can only be achieved in the presence of the both. In the current research the 1000 seed weight, spike number per m2, and seed number per spike are significantly correlated with seed yield. The 25% Nitrogen and Azotobacter compound resulted in the highest yield, and the mere application of the biofertilizer resulted in the lowest yield. Manuscript profile

        To investigate the effect of vermicompost, chemical fertilizers and their application methods on tuber yield and some morphological traits of potato (Agria cultivar) an experiment was carried out in Mahidasht Agricultural and Natural Resources Research Center in Kermanshah Province during 2012-2013 cropping season. The experiment was carried out in a split plot factorial using a randomized complete block design with four replications. Levels of vermicompost (0, 1.5, 2.5, 3.5 t/ha) were assigned to main plots, and chemical fertilizers with three levels (0, 50 and 100 % chemical fertilizer recommended) of the amount of 225 kg/ha of urea, 150 kg/ha of potassium sulfate, 105 kg/ha of triple super phosphate and 52 kg/ha zinc sulfate and on 50% level respectively 112.5, 75, 52.5 and 26 kg/ha and fertilizer application methods at 3 levels (broadcast, one band and two band application) to subplots. The results showed that increasing the amount of vermicompost about 3.5 t/ha and reducing chemical fertilizer by 50% and applying it in two band increased plant height, number of stems per plant and tuber yield. The highest tuber yield was obtained from application of 3.5 t/ha of vermicompost, 50% chemical fertilizer and two band fertilizer applications (37 t/ha). This study indicated the positive effect of vermicompost on potato tuber yield. Thus, it can be suggested that combined application of chemical fertilizers and organic fertilizers may reduce chemical fertilizers usage and reduce also the environmental pollutions.

        The present experiment was conducted to investigate the effect of tillage, organic fertilizers and mycorrhiza on quantitative traits and nutrient uptake in maize. The experiment was performed as a split plot with 4 replications in a randomized complete block design in August of the crop year 2017 and 2018 in Ivan city in Ilam province. Tillage at 3 levels (no tillage, tillage to a depth of 10 cm and tillage to a depth of 30 cm), organic fertilizer at 3 levels (no use, vermicompost 30 tons per hectare and bovine manure 30 tons per hectare) and mycorrhizal fungus Glomus mosseae and it was by soil inoculation method (consumption and non-consumption). In a minimal tillage system, seed yield was 7053.2 kg ha-1, an increase of 21% compared to the least amount of tillage-free treatment. In the minimum tillage system and the consumption of cow manure, the highest grain yield was obtained in the amount of 8198.2 kg ha-1. The interaction of mycorrhizae and tillage on grain yield was significant. In the case of minimal tillage and mycorrhizae, the maximum grain yield was707.1 kg ha-1, which was significantly different from the treatment without tillage and deep in both mycorrhizal and non-amycorrhizal states. According to the results obtained in this study, it was found that soil application at least relative to the deep system has increased plant yield. Manuscript profile
