Maize is an important cereal crop world wide, not only as a staple food in various parts of the world, but also as a major component of feeds for the animals. Adapted to a wide range of climates, the crop is mostly grown between latitudes 30° and 55°, principally in latitudes below 47°. It is a warm weather crop, doing best when temperatures in the warm months range from 21° to 27° C. The judicious use of organic and mineral fertilizers may increase micronutrient density in grain destined for human consumption and play a promising rule in reducing human’s micronutrient deficiency. The integrated nutrient management for crop improvement has been paid little attention in agriculture areas of developing world. Therefore, the present study was executed to evaluate the integrated nutrients use affect on growth, yield and quality of maize.

Wheat (Triticum aestivum L.) is the most important and major cereal crop grown in Pakistan. As staple food of the people, occupying the central position in farming agriculture policies, it dominates all agronomic crops in terms of acreage and production. It is a principal source of carbohydrates and protein both for human beings and animals.Its grains contain carbohydrates 60-90 %, protein 8-15 %, fat 1.5-2.0 %, inorganic ions 1.2-2.0 % and 1 % vitamins such as B-complex and E. Climate change has been identified as the single most yield-reducing factor for wheat. It has many facets, including changes in long term trends in temperature. The impacts of these changing conditions on agriculture are already being seen, yet there are still considerable gaps in our knowledge of how agricultural systems will be affected by both short- and long-term changes in climate, and what implications these changes will have for rural livelihoods, particularly among the most vulnerable.
