Abstract

Effects of SEED PRIMING in Zn and P solutions (with 10, 50 and 100mM Zn from ZnSO4 and 10, 50 and 100Mmp from KH2PO4, respectively) on seed vigor, seedling establishment and GRAIN YIELD of BARLEY were evaluated in laboratory and field conditions (in autumn and spring plantings) in 2005-2006 cropping season. Laboratory experiments were conducted as factorial on the basis of completely randomized design and field experiment was carried out as y randomized complete block design. Analysis of variance of laboratory data showed that percentages of viable seeds and germination, electrical conductivity (EC) of seed leakages, germination rate, root and shoot dry weight and seedling dry weight were significantly affected by Zn priming. All, but EC, were affected by P priming. Zn×P priming interaction was also significant on all traits. All of these traits decreased, with increasing Zn concentration in priming solutions. However, these qualitative traits increased, with increasing P concentration up to 50mM. Further increases of P concentration resulted in reducing the traits. Priming in 10mMZn, 50mMP, 100mMP, 10mMZn+ 50mMP and 10mM Zn + 100mM P solutions were superior as compared to the other priming solutions, in the laboratory. Thus, these priming treatments were applied on seeds tabt were used for autumn and spring plantings. Field traits were not significantly affected by priming treatments in spring sowing. However, in autumn sowing, the highest emergence rate and winter survival was achieved by 100mM P + 10mM Zn priming. In general, priming treatments, particularly 50mM P + 10mM Zn and 100mM P + 10mM Zn improved GRAIN YIELD of BARLEY up to 41% in autumn planting. Highest biological yield in autumn belonged to 100mM P priming treatment and was 34% greater as compared with check. In conclusion, priming could increase GRAIN YIELD and biological yield in average by 29% and 16%, respectively. Therefore, these priming solutions can be applied to improve field performance of winter BARLEY in rainfed conditions.
