Good height, high tillering and profuse branching are traits, desirable for fodder crops. Cereal crops should be short, for better productivity. Developing varieties with agronomic traits that are tailor - made will ensure higher yield..

. These safe storage facilities preserve the genetic diversity of the food supply for most of the human population. That supply is vulnerable to many kinds of pathogenic fungi, viruses, and bacteria. To give an example, a new fungal strain of Southern Corn Leaf Blight destroyed much of the 1970 cor..

The most important products obtained in straight-run refining are petrol, diesel and kerosene. The demand for these products outstrips that obtained during refining of the petroleum. Conversely, high-boiling fractions find lesser use. So, In petroleum industry, the cracking of less use..
