        The barley is one of the most important of cereal plants. This plant tolerance to drought and salinity is relatively good. In order to study the effect of seed rate and nitrogen levels on agronomic characteristics and nitrogen use efficiency of barley cultivar, this study was carried out in Aran and Bidgol region in 2014. A factorial arrangement of treatment in a randomized complete block design with four replications was used. Seed rate treatment (S1= 150, S2= 225, S3= 300 kg ha-1) and nitrogen levels treatment (N1= 0, N2= 75, N3= 150 kg ha-1), were assigned in plots. Each sub plot consisted of 6 row, 5 m long with 50 cm between rows space and 5 cm between plants on the rows was used. In this study characteristics such as: Plant height, number of fertile tiller, 1000 grain weight, number of grain per spike, grain yield, harvest index, protein percent, nitrogen use efficiency, nitrogen appear recovery and amount of nitrogen absorbted were assessed. Results indicated that the interactin effect of seed rate and nitrogen levels treatment on the characteristics such as: nitrogen use efficiency and nitrogen appear recovery was significant. The maximum and minimum of nitrogen appear recovery with average (0.44 and 0.14 %) were obtained by the treatment (150 kg ha-1 of seed + 75 kg ha-1 of nitrogen application) and (300 kg ha-1 of seed + 150 kg ha-1 of nitrogen application), respectively.

        In order to the effect of integrated use of chemical and biological fertilizers on phosphorus use efficiency and some of agronomic characteristics in sunflower, this study was carried out in Markazi province in 2009. A factorial arrangement of treatment in a randomized complete block design with three replications was used. Inoculation with Nitroxin (N0= Control, N1= Inoculation), Inoculation with Barvar-2 (B0= Control, B1= Inoculation) and Application of chemical manure combination of Nitrogen and Phosphorus (C0= N0 + P0, C1= N50 + P25 , C2= N100 + P50 , C3= N150 + P75 kg ha-1). Results indicated that the effect of nitroxin on number of grain per m-2, hectoliter weight and inoculation with Barvar-2 biological manure on number of grain per m-2 were significant. Chemical manure combination of nitrogen and phosphorus on charecteritics such as: stem height, number of effective leaf, number of grain per m-2, biological yield, productivity index of plant, hectoliter weight and phosphorus use efficiency was significant, too. Among the different levels of combination application of chemical manure, that (50 kg ha-1 nitrogen + 25 kg ha-1 phosphorus) with average of phosphorus use efficiency (51.32 %) and (150 kg ha-1 nitrogen + 75 kg ha-1 phosphorus) treatment, with average of phosphorus use efficiency (21.01 %) were significantly superior to the other treatments. Therefore, it can be concluded that with increasing amounts of chemical fertilizers through leaching and waste to reduced fertilizer use efficiency Manuscript profile

        The adverse effects of unfavorable environmental factors are important in warm and dry regions due to limited water resources and evaporation. This study was carried out to determine agronomic traits and oil yield of safflower (Carthamus tinctorius L.) cultivars planting methods at Kashan in 2014. The experiment was conducted as factorial arrangemed in a randomized complete block design with three replications. Treatments were planting methods (flooding, furrow bed method, high water mark, planting on rows) and safflower cultivars (Goldasht, Esfahan local, Soffeh). Each plot consisted of 4 rows, 5 m long with 50 cm between rows space and 5 cm between plants on the rows. Plant height, stem diameter, number of branch, number of unfilled capsuls, number of capsuls per m-2, number of seed per m-2, weight of seeds, biological yield, harvest index of plant and oil yield were measured. Results showed that the interaction between safflower cultivars and planting methods on plant height, number of capsuls per m-2, number of seed per m-2, weight of capsuls grains, biological yield of plant, harvest index and oil yield was significant. The highest and lowest oil yield (389.7 and 254.3 kg ha-1) were obtained with Goldasht cultivar in high water mark and Esfahan local cultivar in planting on furrow. Therefore, safflower planting at high water mark method can reduces the accumulation of salts from the evaporation surface in areas with hot and dry weather, such as kashan Manuscript profile

        Increasing overuse of chemical fertilizers has been causes environmental pollution, degradation of soil and crops. In order to study the effect of integrated application of chemical and animal manures on yield and yield components of spring safflower, the study was carried out in Fatholmobin field of Kashan in 2014. A factorial arrangement of treatment in a randomized complete block design with three replications was used. Chemical fertilizer treatment (Control, 50 kg ha-1 of nitrogen + 25 kg ha-1 of P2O5, 100 kg ha-1 of nitrogen + 50 kg ha-1 of P2O5, 150 kg ha-1 of nitrogen + 75 kg ha-1 of P2O5) and animal manure treatment (Control, 20 ton ha-1, 40 ton ha-1), were assigned in plots. Stem height, number of branches, number of bolls per plant, grains per boll, boll harvest index, 1000 grain weight, grain yield, protein content, phosphorus absorption, nitrogen agronomy efficiency and nitrogen use efficiency were determined. Results indicated that the interaction effects between chemical fertilizer and animal manure on 1000 grain weight, grain yield, protein content, phosphorus absorption, nitrogen agronomy efficiency and nitrogen use efficiency were significant. The highest and lowest of grain yield 1031 and 268 kg ha-1 were obtained in 150 kg ha-1 of nitrogen + 75 kg ha-1 of P2O5 + 20 t ha-1 of animal manure and without application of the chemical and animal manure, respectively.

        In order to effect of urea levels and simultaneous cropping of legumes on agronomic characteristics and total biomass of corn, this study was carried out in field of agricultural research center of Markazi province in 2013. A factorial arrangement of treatment in a randomized complete block design with three replications was used. Urea manure levels [N0= without urea (Control), N1= 75 Kg ha-1 of urea, N2= 150 Kg ha-1 of urea, N3= 225 Kg ha-1 of urea) and simultaneous cropping treatment, (S1= Cultivation of corn, S2= Cultivation of corn + chickpea, S3= Cultivation of corn + cowpea, S4= Cultivation of corn + mung bean) were assigned in plots. Results indicated that the effect of urea levels on the characteristics such as: wet weight of Stem + leaves, wide of ear leaf, dry weight of ear + husk, nitrogen agronomic efficiency, number of legumes grains per m-2, total biomass of corn + legumes and amount of nitrogen absorbtion was significant. Effect of simultaneous cropping treatment on the characteristics such as: wet weight of Stem + leaves, nitrogen agronomic efficiency, number of legumes grains per m-2, total biomass of corn + legumes and amount of nitrogen absorbtion was significant, too. The maximum and minimum of total biomass of corn + legumes (36.42 and 21.47 ton ha-1) were obtained with the (225 Kg ha-1 urea + Simultaneous cropping of chickpea and corn) and (non application of urea + Simultaneous cropping of corn and mungbean) treatments, respectively.
