Tropical tuber crops are known for their biological efficiency, climate, soil and pest resilience, quantity and quality starch for the preparation of several industrial value added products. Their inherent yield potential results in the uptake of substantial quantum of nutrients from the soil necessitating their replenishment through external sources. In addition to the major and secondary nutrients, the micronutrient requirement of these groups of crops are very high though deficiency disorders are manifested in extreme cases.
