Nitrogen

Restricted shoot growth and spindly appearance of plants.

Older leaves at first turn yellowish green; under severe deficiency, the whole plant becomes pale green.

Phosphorus

Plants look lush blue-green or purplish in colour.

The stems very thin and stunted while the roots were brown with restricted development of lateral branches.

Potassium

Yellowish spots in the margins of new leaves which later spread over the leaf surface and subsequently turned      brown, starting with the older leaves.

Plants were stunted, hard and chlorotic.

Calcium

The plants became flaccid; dead spots appeared on the upper stems and the growing apex died.

Upper leaf colouration initially was darker green, but, later turning yellow at the edges and died.

Magnesium

Chlorosis of foliage. Interveinal areas became yellow or greenish yellow while leaf margins remained green.

Mg deficiency starts as interveinal yellowing at the leaf margins on older leaves, which later become brown and withered interveinal yellowing and necrosis.

Sulphur

Younger leaves are affected.

Lower leaves yellowish green while stems were hard and woody.

Boron

Yellowish of the tips of the leaflets oldest leaves with prominent pink veins.

Yellow spots then enlarged.

Copper

Reduction in growth, curling of leaf upwards and inwards with severe scorching.

Poor root development.

Iron

Leaf veins remain green interveinal portion turns yellow young leaves small but not deformed.

Manganese

Reduction in leaf size and development of interveinal orange-yellow mottling over the tip.

Mottling spreads over the whole leaflet turn yellow while the veins remain green.

Molybdenum

Mottling in lower leaves followed by scorching of margins and inrolling.

Extensive flower drop older leaves senesced and dropped off prematurely with death of the growing point.

Zinc

Deficiency appears first on older leaves in the form of interveinal chlorosis.

Inhibit both vegetative growth and fruit production.
