Maize is the third important cereal crop in Pakistan after wheat and paddy. It is cultivated widely in the temperate, tropical and sub-tropical areas in the world. But, its function adversely affected by intense temperature and less humidity environments, gives rise to interfere in efficient pollination and resulted in failure in proper grain synthesis. In Pakistan the average production of maize is less than other maize growing countries of the world. The less production of maize is not because of cultivar but it was because of insufficient supply of water and nutrients, which are basic needs for getting greater production, and our soils and environmental conditions, are not supportive to provide adequate nutrients to crops especially micronutrients. The book in hand is an attempt to alleviate the menace of low production and have encompasses valuable information on various nutrient concentrations of pre and post harvest soil AB-DTPA extractable P and Zn, soil available SO4-S, leaf P concentration, plants density, maize grain yield of variety Jalal. This book can be an asset for the researchers, planner and agriculture students.
