BACKGROUND: Salinity is one of the important a biotic stresses limiting growth and development and the capacity to tolerate salinity is a key factor in crop productivity. OBJECTIVES: The aim of this study was to evaluate the response of sugarcane varieties to uptake and transport of ionic elements under salinity stress. METHODS: This research was carried out to via factorial experiment based on completely randomized design with three replications along 2013 year. The treatments included salinity stress (S1: 0 ds.m-1 S2: 3 ds.m-1 S3: 6 ds.m-1 S4: 9 ds.m-1) and different genotypes (V1: IRC9904, V2: IRC9906, V3: C2, V4: IRC9901, V5: C3, V6: C4, V7: CP48-103, V8: CP57-614, V9: CP69-1062). Studied genotypes included of three old commercial varieties (CP69-1062, CP57-614, CP48-103), three new commercial varieties (IRC9901, IRC9904, IRC9906) and three clones tolerate salinity (C2, C3, C4). RESULT: According result of analysis of variance effect of different level of salinity, genotypes and interaction effect of treatment on all studied traits was significant at 1% probability level. Salinity stress decreased the concentration of potassium and calcium and also increased the concentration of sodium and chlorine in the roots and shoots, so reduced plant biomass, especially in more sensitive genotypes. It seems that in addition to the importance of the root in controlling the uptake of ionic elements, there are mechanisms in other organs that are involved in the uptake and transport of these elements and genotypes also affects it. CONCLUSION: Mean comparison result indicated the highest amount of sodium and chlorine transfer to the shoot was obtained from 9 ds.m-1 salinity level and IRC9906 variety and the lowest one belonged to 0 ds.m-1 salinity level and C4 clone.

BACKGROUND: Management of nutrients, especially nitrogen, in order to economic production, maintains sustainable agriculture, provide food security and prevent environmental pollution is considered to have an important priority. Also select and propose responsible genotype to environmental conditions is a great factor. OBJECTIVES: The current research was conducted to evaluate effect of Azotobacter and nitrogen fertilizer on Nitrogen consumption efficiency indices of some safflower genotypes under dry land conditions. METHODS: This research was conducted via combined analysis factorial experiment based on randomized complete blocks design with three replications along 2015-16 and 2016-17 year. The treatments included different level of Nitrogen (N0: nonuse of fertilizer or biofertilizer as control, N1: Seed inoculation with Azotobacter + nonuse of urea chemical fertilizer, N2: Seed inoculation with Azotobacter + 50% nitrogen from urea source, N3: 100% nitrogen from urea source according soil test) and 6 genotypes (G1: 312-S6-697, G2: PI-401478, G3: PI-253895, G4: PI-306974, G5: Padideh and G6: Sina). RESULT: Result of analysis of variance revealed effect of nitrogen factor and genotypes on all studied traits was significant. In this study combined application of 50% nitrogen chemical fertilizer with Azotobacter in terms of seed yield was not significantly different from the treatment of 100% nitrogen fertilizer application and the nitrogen use efficiency in this treatment was significantly higher than the application of 100% chemical fertilizer. CONCLUSION: Sina genotype and combined use of 50% nitrogen fertilizer with Azotobacter to produce maximum yield and reduce the use of nitrogen fertilizer in order to achieve sustainable agriculture and environmental protection in the dry land conditions and can be recommended to producers in studied region.

The treatments included Nitroxin biologic fertilizer (N1: nonuse of Nitroxin or control, N2: 250 cc.1000m2, N3: 500 cc.1000m2) and phosphorus biofertilizer (P1: nonuse of Phosphorus biofertilizer or control, P2: 100 gr.ha-1, P3: 150 gr.ha-1). RESULT: According result of analysis of variance effect of different level of Nitroxin and phosphorus biofertilizer on all studied traits was significant. Also interaction effect of treatments on number of seed per pod, number of pod per plant and plant height was not significant. Evaluation mean comparison result of interaction effect of treatments on all measured traits revealed the highest amount of seed yield (5096 kg.ha-1), biologic yield (9230 kg.ha-1), 1000-seed weight (1450 gr.ha-1) Seed protein percentage (24%), leaf area index (4.5) and harvest index (53.2%) were noted for N3P3 treatment and lowest amount of mentioned traits belonged to control. The most significant correlation between seed yield and Biologic yield (r=0.95**), number of pod per plant (r=0.81**), 1000-seed weight (r=-0.73**), number of seed per pod (r=0.68**) and Harvest index (r=0.67**), respectively was observed. CONCLUSION: Finally according result of current research application 500 cc.1000m2 Nitroxin and 150 gr.ha-1 Phosphorus biofertilizer had the highest amount of studied traits and it can be advice to producers in studied region.

BACKGROUND: In organic agriculture, one management goal is to increase and maintain soil quality with a high biological activity. Organic cropping system often has to deal with a scarcity of readily available nutrients in contrast to high input cropping system which relies widely available on soluble fertilizers. Nanotechnology such as using Nano-scale fertilizer particles may offer new techniques in improving existing crop management. OBJECTIVES: Current study was carried out to assess effect of different level of vermicompost and Nano iron fertilizer on morphological characteristics, chlorophyll content and crop production of corn. METHODS: This research was conducted according split plot experiment based on randomized complete blocks design with three replications along 2018 year in research farm of Islamic Azad University of Ahvaz Branch. Main plot included three level of vermicompost (V0: nonuse of vermicompost or control, V1: 5 t.ha-1 vermicompost, V2: 10 t.ha-1 vermicompost) was consumed at planting stage. Also subplots consisted four level of Nano iron fertilizer (F0: Nonuse of Nano iron fertilizer or control, F1: 0.002 L.ha-1, F2: 0.004 L.ha-1 and F3: 0.006 L.ha-1 Nano iron fertilizer) was used at 3 to 4 leaves stage. RESULT: According result of analysis of variance effect of different level of vermicompost and iron Nano fertilizer on all studied traits was significant but interaction effect of treatments only on ear loss length was not significant. Assess mean comparison of interaction effect of treatments on all measured traits revealed the highest amount of seed yield (545.7 gr.m-2), plant height (273.6 cm), Stem diameter (22.67 mm) ear length (26.73 cm), ear diameter (67.57 mm) and Chlorophyll index (2.951 spad) were noted for V2F3 treatment and lowest amount of mentioned traits belonged to control. CONCLUSION: Use 10 t.ha-1 vermicompost with 0.006 L.ha-1 iron Nano fertilizer led to produce the highest amount of crop production, morphological traits and chlorophyll content and can be advice to farmers.
