        In order to evaluate of some bean cultivars to drought stress, as well as identification the favorable tolerance indices to drought stress, two separates experiments into completely randomized design with 3 replications was conducted in green house at faculty of agriculture, Gonbad Kavoos University, in 2013. The first experiment included study of moderate water stress after podding (30% water depletion of filed capacity) and the second experiments included study of severe water stress after podding (70% water depletion of field capacity) on different bean cultivars included With bean ( Daran), Red bean (c.v. Azadshahr), Green bean ( Sanray), and Pinto bean ( Saman). The results of present study showed that cultivars had significant differences on all studied indices except for ToL, SSI and STI in full irrigation and slight water stress. It was also observed that there was significant and positive regression between seed yield and indices like MP, GMP and HARM in full irrigation and slight water stress condition in 1% confidence level. Therefore, these indices could be most favorable indices to select tolerance cultivars under slight water stress. the highest amount of some indices namely MP, GMP and HARM was found in Pinto bean. In intensive stress condition, the cultivars had significant differences on TOL, MP and GMP indices in 5 % confidence levelTherefore, the most favorable index to select tolerance cultivar was identified in intensive drought stress. On the basis of GMP index, red and pinto beans were confirmed as preference cultivars in intensive stress. Manuscript profile

        Quantitative information regarding biomass partitioning in faba (Vicia faba L.) is limited. The purpose of this study was to obtain the values of the distribution coefficients of dry matter between different parts of faba plant under different sowing dates and densities conditions. This experiment was conducted in Gonbad Kavoos during 2012-2013 in rainfed conditions. Experimental design was a factorial arrangement of treatments based on randomized complete block design with four replications. The treatments were combinations of sowing dates (27 November 2012, 14 December 2012 and 7 January 2013) and four plant densities (8, 12, 16 and 20 plants m-2). Dry weight of the separation of different organs and phenological stages were measured between emergence and maturity. A linear relation was found for biomass partitioning between leaves and stems before podding stage (R3). Ratio of dry matter distribution among leaf and stem on 27November 2012, 14 December 2012 and 7 January 2013 were 62:37, 60:39 and 54:40, respectively. Dry matter that was dedicated to stem more than leaf. On the other hand competition between of plants had not significant effect on dry matter distribution. Dispersion between data was more after podding stage than before it, which is probably due to translocation of dry mater. Manuscript profile

        3 - Efficiency of individual application and mixing herbicides on some traits of Bifora testiculata and wheat (Triticum aestivum)

        An experiment was conducted to evaluate individual application efficiency and mixing herbicides of broad leaf killer on control of European bishop (Bifora testiculata) as well as traits of growth, yield and components yield of wheat (Triticum aestivum) based on the Randomized Complete Block Design (RCBD) in four replications in research farm of Gonbad Kavous University in 2014-2015 growing season. Treatments included Tribenuron methyl (Granstar), Bromoxynil+MCPA (Bromicide MA ), 2,4, D + Dicamba (Dialen super), mecoprop-p + dichloprop-p + MCPA (Duplesan super), 2,4, D, mixing of the Tribenuron methyl with other herbicides and control (without application of herbicides and hand weeding). Results showed that effect of the various treatments of control (without application of weeds and hand weeding) and herbicides on dry matter, plant desity and total chlorophyll content of Bifora testiculata and whole measured traits of wheat were significant (p<0.01). In the Overall, mixing herbicides had a more decrease effect on the plant desity, dry matter and total chlorophyll content of Bifora testiculata in comparison with individual application. In this study, the hieghest yield were obtained in the treatment of Tribenuron methyl along hand weeding about 3527 and 3720 Kg/h respectively. In return, the lowest yield were found in the treatment of without application of herbicides (1864 Kg/h). The mixing of Tribenuron methyl with mecoprop-p + dichloprop-p + MCPA and 2,4, D + Dicamba caused highest negative effect on Bifora testiculata, while these treatments had a lower negative impact on seed number in spike and seed yield over individual application Manuscript profile
