A study of drought resistance measures in maize. I. MOC drought resistance chemicals and floret differentiation and yield

Maize was treated with 4 formulations of drought resistance inducing chemicals applied either by soaking the seed or spraying onto leaves. Spraying plants under drought stress increased the length of ears by 18.79%, increased their width by 13.24% and increased the grain number/row by 14.13%. Spraying before stress occurred increased yields by 5-11% in the field and in pot trials reduced the yield reduction due to drought stress.

The effect of soaking seeds in MOC drought-resistance chemicals in enhancing drought resistance in maize. Maize seeds were soaked in MOC chemicals [a mixture of antitranspirants?] before sowing to increase drought resistance.
