Abstract:

The effects of the exogenous potassium nitrate application on major antioxidant enzymes, photosynthetic pigment content, malondialdehyde, hydrogen peroxide and free proline were investigated in salt-stressed (75 mM NaCl) maize genotype (ADA 9510). Plants were grown in growth chamber for ten days. After five days of applications (control, 0 mM NaCl), S75 (75 mM NaCl), potassium nitrate (3 mM KNO<sub>3</sub>) and S75 + potassium nitrate (75 mM NaCl + 3 mM KNO<sub>3</sub>), plants were harvested. The results showed that salt stress significantly decreased chlorophyll a, chlorophyll b and total ch

Abstract:

Saline and sodic (alkali) soils can significantly reduce the value and productivity of affected land. By estimation, slightly more than one-fourth of irrigated farmland in the United States is affected by soil salinity. Ions most commonly associated with soil salinity include the anions chloride (Cl<sup>–</sup>), sulfate (SO4<sup>=</sup>), carbonate (HCO<sub>3</sub><sup>–</sup>), and sometimes nitrate (NO<sub>3</sub><sup>–</sup>) and the cations sodium (Na<sup>+</sup>), calcium (Ca<sup>++</sup>), magnesium (Mg<sup>++</sup>), and sometimes potassium (K<sup>+</sup>).

Abstract:

In the first two years of study, method of cultivation did not affect the emergence of cucumber seedlings. In the third year, a drought occurring during the spring was the cause of poor seedling emergence on no-tilled plots. Six weeks after seed sowing, the shoots of cucumbers grown on the no-tilled plots were much shorter, especially in the last study year. At the time of cucumber seed sowing, no-tilled soil contained less phosphorus and potassium and in the middle of the fructification period the content of these elements in cucumber leaves was higher under no-tillage cultivation.
