To study the effects of sowing pattern and foliar application of Fe, Zn, and B on yield and yield components of corn Cv. 704 an experiment was done in stripe plot on the basis of randomized complete block design in four replications during the crop year of 2006 in the Agronomical Research Station of Khoy. In this experiment the first factor was in two levels: rectangular and square planting patter. Second factor was foliar application of micronutrients in eight levels which included control, foliar application of Fe, Zn, B, Fe+ Zn, Fe + B, Zn + B and Fe + Zn + B. Foliar application was done in 5000 ppm concentration. Results showed that ear length and seed number on ear were only affected by micronutrients foliar. Interaction of the two factors was significant on harvest index. In general, planting on square pattern and foliar application of micronutrients improved the yield components so that the highest yield was obtained in square pattern with 9.96 ton / ha and in foliar application of Fe, Zn, and B with 10.4 tons/ha.

Wheat stripe ( yellow ) rust is an important disease in Iran. In order to evaluate the reaction to yellow rust, 64 wheat doubled haploid lines resulted from wheat and maize hybrid chromosome elimination method were tested relative to three wheat yellow rust disease pathogen pathotypes in Sari region. These pathotypes involved 70E34A+, 166E14A+, 70E10A+. Wheat doubled haploid lines were tested in seedling stage in greenhouse condition by three resistant control cultivars ( Parsi, Sivand and Morvarid ) and sensitive Bolani cultivar. All lines and cultivars were planted in three replications in plastic pots in a culture room. In one and two leaves stages, the seedlings were inoculated with urodiniospores of each pathotype separately. After 14 to 25 days, the infected type of each line was recorded based on 0 – 9 scale. Resistance was measured by infected type, latent period, sprout size and sprout density. The analysis of variance showed a significant difference among genotypes. These lines can be used as resistance resources relative to pathotypes in improvement programs. The results indicated that doubled haploid system can be a useful method for production of optimal resistant lines in a short term. Manuscript profile

Comparison of chemical suckericides and manual desuckering affects on yield of tobacco. After topping activities in different treatments, an experiment was done in research center of Tirtash for one year in the agricultural year of 2009-10 in order to investigate the effects of neem oil, prime plus solution and fatty alcohol and tobacco sucker control. This experiment was arranged on randomized complete block design with three replications. The investigated treatments included neem oil in the amounts of 0, 5, 10, 15, 20, 25 and 30 lines per hectare; prime plus solution in the amounts of 4 liters per hectare, fatty alcohol solution in the amounts of 18 liters per hectare and manual control treatment. The impacts of different sucker controllers on the properties of number, wet weight and dry weight of the suckers were meaningful in one percent. Minimum amount of wet weight and dry weight of suckers from treatment of prime plus and maximum number of suckers from manual control treatment and maximum, wet weight and dry weight of suckers of not using of neem oil were derived as maximum and minimum wet weight and dry weight of the leaves which belonged to the treatment of prime plus and the treatment of not using of neem oil.

To study the effect of Soil Fertilizing Management on Seed Yield of thin walled pod pumpkin an experiment was conducted in agricultural farm of agronomy research center of Sanandaj based on factorial randomized complete block design with three replications. Treatments included levels of chemical fertilizer based on soil test( control zero, 50 and 100 percent of the recommended chemical fertilizer ) and type of bio-fertilizers including no control application of organic fertilizer ( compost ), nitrocara, phosphate bio-fertilizer 2, and compound of compost + nitrocara + phosphate bio-fertilizer2. In this study, 1000-kernel weight, number of seeds per fruit, average weight per fruit were measured. Analysis of variance showed that the effects of chemical fertilizer on all traits, except for grain weight and number of fruits per plant were significant and also the biological fertilizer treatments had important impact on all traits except for seed weight, fruit diameter and number of fruits per plant. The interaction between organic fertilizer and biological fertilizer had significant effect on all traits except for seed weight and number of fruits per plant. Comparison of means showed that the combination of compost + nitrocara + phosphate fertile2 with 50% and 100% chemical fertilizer had the highest amount of number of seeds per fruit, fruit weight, fruit diameter, fruit yield and grain yield. In this research treatments of compost + nitrocara + phosphate bio-fertilizer 2 with 50% and 100% chemical fertilizer without bio-fertilizer and 43.38 percent in comparison with 100 percent chemical fertilizer without bio-fertilizer and 84.92 percent compared with control of both treatments. So, by using of compost + nitrocara + phosphate bio-fertilizer2, can be saved 50 percent in consumption of chemical fertilizers. Manuscript profile

To study the growth stimulation of sugar beet ( Beta Vulgaris L. )under mild salinity, a field study was conducted in Agricultural Research Center in Miandoab in combined analysis design with three replications during the crop year of 2013 in two separated normal and mild salinity ( Ec = 4-5-ds/m ). Combined analyses of variance showed that genotype in environment interaction was statistically significant on sugar content, sugar yield, extraction of sugar coefficient and white sugar yield. Interactions of genotype in specific conditions had significant effect on sugar percentage, sugar yield, coefficient of sugar extraction and white sugar yield. In this research, mild salinity condition induced sugar beet growth and increased traits such as root yield, sugar content, molasses of sugar, white sugar content, sugar yield. The mild salinity also increased it up to 10.5% and 20% compared with normal conditions. Genotypes of 14, 15 and 16 respectively, by Origen 004, 005 and Isela, in average conditions of 9.04, 10.34, 10.81 in normal condition and 16.59, 16.37 and 11.93 ton/ha in stress condition showed the highest sugar yield and were identified as the most suitable genotypes in both situations. In both normal and mild saline conditions between root yield, sugar content, sugar yield and its extraction a positive and significant correlation were observed. The results of factor analysis showed that in normal conditions, there were four factors of 92.5 percent and in mild salinity three factors of 87.80 percent which justified the total variation in root and sugar yield.

To evaluate the effect of foliar application of zinc and boron fertilizers on quantitative and qualitative characteristics of grain maize, an experiment was conducted with two factors using factorial in a randomized complete block design in Sar-e Pol-e Zahab. The first factor was zinc in four levels ( zero, 0.7, 1.4 and 2.1 kg/ha-1 ) and the second factor was boron in four levels ( zero, 0.3, 0.6 and 0.9 kg/ha ). Summary results showed that the effect of zinc and boron factors were significant on the stem diameter, number of kernels per row, 100 kernel weight, leaf area index, the amount of zinc and boron in the grain, protein percent and yield and grain yield at the 1% level statically. By increasing the amount of zinc fertilizer consumption, increased the stem diameter, leaf area index, number of kernel per row, 100 kernel weight, the amount of Zn and B in the grain, the amount of protein in the grain and the grain yield. The highest and lowest grain yield belonged to 2.1 kg/ha of Zinc and without the consumption of Zinc fertilizer treatments with 9.560 and 8.000 t ha-1 respectively. The 0.6 kg/ha of boron fertilizer treatment had greatest effect on the stem diameter with 28.9mm, leaf area index with 3.89, seed depth with 11.67 mm, number of kernels per row, with 41 grain and grain yield with 9.43t/ha, and this treatment was the best one. The effect of Zn and B fertilizer interaction on the yield and yield components showed that the treatment of 2.1 kg/ha oh zinc × 0.6 kg/ha boron was superior for all traits such as grain yield with 10.93 t/ha.

To evaluate the priming effect of potassium resources and foliar spray of micronutrient on the yield and yield components of sunflower ( Farrokh cultivar ) a two factorial experiment was carried out at Agricultural and Natural Resources Station of Khoy ( W. Azarbaijan-Iran ) in the crop year of 2014. The experiment was conducted on a randomized complete block design with 12 treatment and 3 replications. The priming factor was accompanied with the three levels of potassium chloride, potassium nitrate, and potassium sulfate; spraying factor accompanied with four levels of non-spraying and spraying with zinc, boron, and a combination spraying of zinc and boron. The variance analysis revealed a significant effect of priming of the seed on the diameter, number of seeds per head, and seed yield, but it had no significant impact on the other traits. The maximum number of seeds per head was 656.7 for zinc spraying and 669.7 for boron spraying. The minimum number was 511.8 for non-spraying. Combined spraying of boron and zinc showed maximum yield of 3899.9 kg per hectare and non-spraying showed the minimum yield of 2928.8 kg per hectare. The bilateral effect of these two factors affected the traits, seed yield, shoot-ash percentage, and harvest index. However, the highest seed yield was observed as 4040 kg/h for priming with potassium chloride and spraying with boron and the least seed yield was observed as 2652 kg /h for priming with potassium sulfate to increase the head diameter was more effective than other sources of potassium. Simultaneous spraying of zinc and boron increased the diameter, number of seeds per head, seed yield, and harvest index, while non-spraying reduced the number of seeds per head, seed yield, and biological yield. The correlation of bush diameter with seeds number, seeds yield and biological yield were significant, and so were the seed number correlation with seed yield, biological yield and its hollowness percentage.
