Effect of Soil application of Zn & Foliar application of B on Maize

Maize is one of the most versatile emerging crops having wider adaptability under varied agro-climatic conditions. Globally, maize is known as "queen of cereals" because it has the highest genetic yield potential among the cereals.Maize is one of the crops most sensitive to Zinc deficiency. Zn is a micronutrient which enhances the grain productivity in the maize production. The supply of Zn in the crops can be done directly on the soil, as fertilizers, via foliar fertilization or seed treatments. Boron application improves growth, and enhances stress tolerance in plants and improves grain production. World-wide Boron deficiency is more extensive then the any other plant micro nutrient deficiency boron deficiency caused sterility in maize, in sufficient levels of available boron soil reduce crop yield, impair grain quality and increase the susceptibility of crops to diseases. Boron is considered as an essential element for plant growth and development, sexual reproduction in plant is more sensitive to B deficiency, then vegetative growth.
