The effect of adding potassium and sodium to the soil on the yellow corn plant content of these elements

Abstract

A biological experiment was conducted in Al kut Palms station, Wasit Province during spring season 2015 to study the effects of applying Potassium and Sodium on content of Potassium and Sodium and growth of yellow corn (Zea mays L) variety hybrid compete.
Soil samples were taken from the Al kut Palms station - Wasit province. And air dried, milled and passed through a sieve 3.5 mm then 8 kg soil was put in pots. Calcium nitrate fertilizer (15.5% N) level 160 kg.ha-1, and tri superphosphate fertilizer (21% P) at level of 100 kg P ha-1 were added and mixed with the surface layer. Potassium was added as Potassium sulfate (42% K) at level of (0.205 centimol. K. kg -1 soil). The soil was salted with Sodium chloride, Sodium carbonate and Sodium sulfate at fixed concentration ( 0.06 centimol . Na. kg-1. Soil). The Pots were planted with maize plants as one plant per each pot. The growth of maize tested for 45 days. The results showed that the addition of sodium salts positively affected in the sodium concentration in the vegetative, but potassium Add negatively affected in sodium content and affected add sodium salts negative in potassium content, while potassium addition positively affected in potassium content. As well as the results showed add sodium salts led to lower content ( K / Na) ratio in the vegetative while Addition of potassium to increase the proportion of concentrations ( K / Na) in the vegetative .As well as the addition of sodium salts influence negative in plant traits which are plant high and leaf area and dry weight plants and the weight of the root portion, and that the sodium chloride salt most influential in the mentioned qualities, while adding potassium sodium reduced the impact on the qualities of the above mentioned.
