Introduction of course

This course will enable the students to understand plant nutrients and mechanisms of their uptake by plants. There will be detailed discussions about the available forms of different plant nutrients, their fertilizers / sources, mode of absorption, assimilation and redistribution in plants. In addition, there will be a brief description of plant growth hormones, their classification, site of synthesis and action as well as their commercial uses.

LEARNING OUTCOMES

  1. To introduce the students about concept of mineral nutrients and mineral nutrition.
  2. To familiarize students about mechanism of uptake, translocation and metabolism of mineral nutrients.
  3. To make students able to distinguish between deficiencies symptoms of different plant nutrients.
  4. To make aware students about functions of plant growth regulators.
  5. To provide know-how about mineral nutrition and growth regulators.
