Effect of Biological Treatment under Water Stress Conditions on Maize (Zea mays L.)

Abstract

A field experiment was conducted in Padang Besar, Perlis, Malaysia from 2014 and 2016 four seasons. In each year, the experiments have been implemented in order to study the effect of three levels of irrigation water (25% (no stress), 50% (moderate deficit), 75% (water deficit) of field capacity), and five concentrations of salicylic acid (0, 50, 100, 200, 300 ppm) evaluate the biological treatment by using salicylic acid in raising the possibility of corn on production in conditions of water stress and lack of irrigation water the results of the research show the possibility of using salicylic acid in raising the ability of corn to withstand the conditions of water stress and increase production salicylic acid spray reduced the number of days from planting to maturity the results also showed the possibility of using Salicylic acid in increasing the height of the plant to the normal limit as for the paper area, its rate has increased significantly in response to saline spray under water stress conditions the results indicated that the use of salicylic acid as a vital agent was used to increase the ability of corn to resist extreme conditions of water shortage.
