To investigate the response of corn to combined APPLICATION of chemical fertilizers with rhizobacteria plant growth promoting, an experiment was conducted in 2017 at Research farm of Agricultural AND Natural Resources Campus of Tehran University, Karaj, Iran, in a rANDomized complete block design with four replications. Four nutritional treatments including T1 (Control treatment without applying fertilizer), T2 (Just PGPRs), T3 (Use chemical fertilizers based on soil test) AND T4 (T3 + PGPRs) were considered. According to the results, the highest total dry weight (3.9 kg/m2), crop growth rate (79.8 g.m-2.day-1), net assimilation rate (15.3 g.m-2.day-1) AND grain yield (18.2 ton.ha-1) were observed in T4 treatment AND T2 treatment produced the highest  leaf area index (5.3), leaf area duration (205.2) AND specific leaf weight (78.5 g.m-2) . Also, the lowest value of all traits was observed in in T1 (control) treatment. The results showed that the presence of rhizobacteria plant growth promotioninduction in the corn nutrition program increased the growth AND growth indices of the plant. Combined APPLICATION of chemical fertilizers with rhizobacteria plant growth promoting resulted in the highest growth AND final grain yield of corn.

Different types of contact, including contact between node pairs, any-contact of nodes, AND contacts of the entire network, are used to characterize social relations in mobile social networks. Different modes of routing, from the point of view of message delivery semantics, encompass unicasting, multicasting, any-casting, AND broadcasting. Studies have shown that using probability distribution functions of contact data, which is mainly assumed to be homogeneous for nodes, improves the performance of these networks. However, there exists an important challenge in studies on distributions. A lot of works apply the distribution of one type of contact to other types. Hence in routing APPLICATIONs, it causes to use of the distribution of one type of contact for any mode of routing. This study provides a complete solution to model each type of homogeneous contact data distribution AND to use them in different modes of routing. We propose a routing algorithm that uses this new model. Results show that our solution improves the average latency of comparing methods Epidemic, TCCB, AND DR about 3.5-times, 30%, AND 45%, respectively. It achieves a delivery rate of about 5% AND 6%, AND average latency about 6% AND 8% better than that of DR AND TCCB, respectively.

More than 22% of the world's agricultural lAND is saline, AND this trend continues to increase with climate changes. Salinity stress causes leaf color change, osmotic stress, ionic toxicity, prevents growth, photosynthesis AND plant performance. Due to their size less than micron, metal nanoparticles have a great absorption AND transmission power in plants. Salinity stress is a major problem in hot AND dry areas under tomato cultivation. For this purpose, investigating the mutual effects of the size AND type of ZINC oxide AND iron oxide nanoparticles on the improvement AND change of growth AND increasing the resistance to salt stress in tomato plants of the early urbana variety were carried out in the form of a completely rANDomized AND factorial design with 4 replications, at a significant level of 5%. In this research, ZINC oxide nanoparticles in 25 AND 50 nm sizes, iron oxide in 25 nm sizes AND sodium chloride in 0 AND 75 mM levels were used. Nanoparticles AND salinity treatments were both applied to the plants. The results showed that salt stress led to a decrease in plant growth parameters such as shoot AND root length, leaf area, RWC, ion leakage. Also, NaCl led to an increase in the accumulation of prolin AND other aldehydes, sodium, iron AND ZINC. The APPLICATION of nanoparticles had a slight effect in stress-free conditions, but in stressed conditions, these two nanoparticles alone AND especially in combination neutralized the effect of salinity AND reduced the damage caused by salinity stress.

To assesse the iron AND silicon effects on the yield AND physiological characteristics of green pea, WANDo cultivar by ASGrow Corporation was used in three levels of iron chelate (0.05, 0.1 AND 0.3 gr per l-1) AND silicon (0, 14 AND 28 mg per l-1), as a factorial experimental in completely rANDomized design with three replications. In this experiment, characterisics such as fresh AND dry weight of grain, the number of grain per pod, concentration of Fe, Cu, Mn, Zn AND Si in leaf AND grain were measured. Results showed that the interaction of Fe AND Si was significant at p<0.01 on grain fresh AND dry wigeht, concentratin of leaf AND grain Fe, leaf Mn, leaf AND grain Zn AND leaf Si AND the APPLICATION of Fe AND Si was significant separately, on other traits such as number of grain per pod, concentration of leaf AND grain Cu, Mn AND Si in grain.  The Mean squares showed that the APPLICATION of Fe AND Si significantly increased fresh AND dry grain weight AND Si laef concetration AND decreased the concentratin of leaf AND grain Fe AND Mn as well as grain Mn.  The enhancement of Fe AND Si APPLICATION separately decreased the concentration of Mn, Cu AND ZINC leaf AND grains, but the Si concentration of leaf AND grain were increased by Si APPLICATION. The concentration of Fe, Mn, Cu AND Zn were decreased in leaf AND grain because of antagonistic effects. It can be concluded that Si reduces the harmfull effects of high levels of iron toxicity AND the APPLICATION of 0.1 g/l AND 25 mg/l can be recommended as the best treatments.

In this paper, a novel LNA design based on improved noise cancellation technique in the frequency range of 27 to 31 GHz.is presented The proposed LNA is suitable for millimeter wave 5G wireless communication. The first stage of this two-stage LNA is designed with noise cancelation approach to decrease the noise figure of the system. In order to improve the design method, we utilizes a negative feedback by implementing a couple inductor with a transformer connection. The negative feedback provides an acceptable input matching AND control the gain to increase the bAND width. The cascode structure is used in the second stage for its higher gain AND stability AND better reverse isolation at millimeter wave frequency. Furthermore, an inductor is utilized to boost the gain with neutralizing the capacitance of node between two transistors in a cascode structure. The CMOS silicon on insulator (SOI) is utilized to provide a high level of integration AND low power consumption with the minimum cost. The proposed LNA is designed with 130 nm CMOS technology AND has 22.14 dB gain with 1.86 dB noise figure at 29 GHz. The 3-dB bANDwidth of the designed LNA is 4 GHz (14%) AND its DC power consumption is 33.4 mW. The IIP3 is -16dBm AND input reflection coefficient is better than -10dBm in the frequency range of interest. The proposed LNA is simulated by ADS software.

Introduction: Despite the P vitality for rice cultivation, its recovery index in paddy soils is very low AND less than 25% of added P, AND the rest goes out of reach of rice plant through the P fixation by soil particles at different fractions. Also, despite abundant studies on the effect of basal soil P APPLICATION, we face a lack of knowledge on research findings of the P splitting APPLICATION AND its effect on soil Zn concentration AND tissues Zn content. Thus, the current research project was done to explore the effect of P splitting APPLICATION at flooded conditions on the soil AND rice plant tissues P AND Zn variation trend at the different rice growth stages of two more common varieties (Hashemi AND Guilaneh varieties). Materials AND methods: The outdoor pot experiment was conducted on a three factors factorial experiment in a rANDomized complete block design with three replications in 2017 at the research farm of the rice research institute of Iran, Rasht. The experimental treatments were: PHOSPHORUS fertilizer split APPLICATION at five levels, soil at two levels, AND rice varieties at two levels (Hashemi (local variety) AND Guilaneh(improved variety)), The P APPLICATION treatments were: control (no added P), 100% basal, P split APPLICATION at 50% basal AND 50% at 20 days after transplanting (DAT), P split APPLICATION at 50% basal AND 50% at 60 days after transplanting (DAT), P split APPLICATION at 50% basal, 25% at 20 days after transplanting, AND 25% at 60 days after transplanting. Results: The results indicated that the highest soil available P AND Zn concentrations were recorded at the flowering stage about 95. 3 AND 90. 10, AND 8. 6 AND 8. 7 mgkg-1by two AND three P split for Hashemi AND Guilaneh, respectively. Also, the maximum P of rice grain was obtained about 0. 17 AND 0. 20 mgkg-1 for Hashemi AND Guilaneh, respectively. The Zn content of rice grain at P split pots was significantly more than control AND 100% basal APPLICATION. The highest agricultural recovery (13. 31 AND 12. 72), physiological (693. 19 AND 740. 10) AND physiological-agricultural efficiency (482. 00 AND 753. 00), P use efficiency (5. 34 AND 5. 66), AND apparent recovery (1998 AND 1272. 22 kg kg-1) were found for Hashemi AND Guilaneh, respectively, in the two AND three P split APPLICATION. Furthermore, stepwise multiple regression analysis revealed that the soil available P concentration at ripening stage, Zn content of the grain, AND Zn concentration at rice aerial parts can explain 52% of grain yield variations for studied rice cultivars. Conclusion: The three-stage P splitting (50% soil basal, 25% 20 DAT, AND 25% 60 DAT) increased the Zn content of the Hashemi variety by about 54. 72% at slit loam soil, whereas the Guilaneh rice variety was received a 37. 5% increase in Zn content of grain in silty clay through two-stage P splitting (50% soil basal AND 50% 20 DAT) compare to control (100 % basal). It can be concluded both three AND two-stage P splitting might be positively significantly effective on rice grain nutritional quality.

To evaluate the effect of nitrogen AND water withholding in vegetative growth stage of corn on efficacy of nicosulfuron AND 2,4-D+ MCPA an experiment was conducted as a factorial arrangement in a rANDomized complete block design with three replications at Tarbiat Modares University in 2017. The first factor contained four treatments including APPLICATION of nicosulfuron, 2,4-D+ MCPA, weed free AND weed infested as control. The second factor consisted of normal irrigation AND water withholding from 4 to 8 leaf stage. Third factor contained either urea APPLICATION or no fertilizer APPLICATION. Normal irrigation AND nitrogen fertilizer APPLICATION significantly increased nicosulfuron AND 2,4-D+ MCPA efficacy in weed control AND total weed dry weight decreased to 341 AND 361 g.m-2 respectively compared 1370 g.m-2 as weed infested. Nicosulfuron AND 2,4-D+ MCPA reduced weed total dry weight significantly under irrigation withholding. Grain yield increased with APPLICATION of nitrogen AND nicosulfuron. Grain yield was higher with APPLICATION of 2,4-D+ MCPA than nicosulfuron without nitrogen APPLICATION under irrigation withholding. APPLICATION of nicosulfuron with nitrogen APPLICATION provided satisfactory weed control AND increased grain yield.

Introduction: Potato production has fourth rank in the world after rice, wheat, AND maize with the production of 321 million tons from 19.6 million hectares. In Iran this important crop has third rank after wheat AND tomatoes with the production of 4.6 million tons. Potato is a temperate crop, growing AND yielding well in cool AND humid climates or seasons, but it is also cultivated in tropical to sub-polar climatic regions, AND represents a major food crop in many countries. Potato is sensitive to nutrients deficiency especially PHOSPHORUS AND ZINC. At least one-third of the cultivated soils globally are estimated to contain too low amounts of bioavailable ZINC for optimal crop production. In Iran more than 70 percent of irrigated soils suffer from ZINC deficiency. Many reasons have role in mentioned deficiency such as calcareous AND alkaline soils, lower organic carbon AND higher APPLICATION of PHOSPHORUS fertilizer. So, evaluation of ZINC fertilizers efficiency is essential under different soil PHOSPHORUS conditions. …
