Explanation

Nutrients are raw materials required for synthesis of protoplasm as well as source of energy. Nutrients should be rich in nitrogeneous and carbohydrates for energy and cell wall syntheisis. All types of micronutrients and macronutrients should be available for proper growth. water is required for cell elongation, maintenance of turgidity of growing cells and providing medium for enzyme action. Even slight deficiency of water reduces growth. It may, however, promote differentiation. water stress completely stops growth.
