Investigation on the effect of humic and biominic acid Foliar on yield and yield components of barley under cut irrigation condition

In order to evaluate the effects humic acid and Biomin on yield and yield components of two barley cultivars conditions water stress experiment was. conducted in the city Damghan. In this experiment was conducted a split split plot randomized complete block design with three replications. The samples were cut water treatments (control and with held irrigation stage BBCH41) as the main plot and two varieties of barley (Kavir and Nusrat) as sub-plot and applied at four levels (control, Humax, Biomin, Humax and Biomin 50: 50) as sub-sub-plot. A result showed that the Effect of water deficit on spike, grain number per spike, 1000 grain weight and grain yield was statistical level of one percent means was significant. Effect of cultivar apart from yield traits in other traits (number per spike, grain number per spike and grain weight) in the statistical level of significance was five percent means. Comparison showed that the highest was obtained the Nusrat cultivar spraying in the treatment Humax Biomin spike characteristics, yield treatment. The Max amount was achieved interaction of stress × cultivars × spraying showed that Nusrat the irrigation and spraying treatments humax biomin in spike (4.36 N.o), grain number per spike (46.8 N.o), 1000 grain weight (45.06 gr) and green yield (8998.7 Kg.ha)
