| Abstract: |
This study was conducted in 2006 and 2007 experimental seasons to throw some lights on possibility of minimizing the injuries resulted by saline irrigation water through investigating the effect of foliar spray with some nutrient elements in order to alleviate such disorders observed on growth and nutritional status of two banana cultivars suckers. So, a factorial experiment was designed to study the specific and interaction effects of three factors (banana cultivar, Cl:SO4 ratio of saline solutions used for irrigation and sprayed nutrient elements P, K, Zn). Data obtained displayed that all evaluated growth measurements considerably responded to specific effects of 3 investigated factors. Since, saline stressed banana plants achieved some positive effects by P, K and Zn sprays, where an increase in most measurements of either growth (pseudostem height and circumference; leaves number & area and fresh & dry weights of plant organs) or chemical composition (leaf photosynthetic pigments, N, P, K, Mg, Fe, Mn and Zn contents) associated with a noticeable reduction in both leaves senescent rate and some chemical constituents content (leaf proline, Ca and Na) were detected. Moreover, raising Cl:SO4 of saline solution used for irrigation exhibited an opposite trend to that found with P, K, Zn sprays. Meanwhile, the specific effect of cultivar pointed and that Grand Nain cv. had greater values of most vegetative growth and chemical constituents than Williams cv. except (leaves senescent rate, leaf proline, Ca and Na content). Consequently, the saline stressed banana plants (especially those of Grand Nain cv. irrigated with saline solution of lower Cl:SO4 ratio) when sprayed with K or Zn exhibited the greatest values of most measurements for both vegetative growth and chemical constituents associated with the least values of (leaves senescent rate, leaf proline, Ca and Na contents). Accordingly, it cold be concluded that saline solution of 3000 ppm, SAR 6 and lower Cl:SO4 could be safely and when combined with K and/or Zn sprays |
