The availability of Nitrogen in different soil samples were ranged 234 to 287 kg/hect. Presence of Nitrogen is an essential part for carbohydrate, fats, oil and also an essential ingredient of proteins. The deficiency of nitrogen shows uniform yellowing of older leaves including veins, leaves that will eventually turn brown and die. The excess of nitrogen shows plants will be dark green in colour and new growth will be succulent. The availability of Phosphorous in different soil was ranged in between 12.76 to 15.34 kg/hect.
