Effect of micronutrients on guava (Psidium guajava L.): A review paper

Abstract

Micronutrients provide special lubricants required for variety of energy transfer mechanism within the plants. They are as important as macronutrients for growth, yield and quality of fruits. They are required in traces. Micronutrients are involved in all metabolic and cellular functions. Micronutrients happen to improve quality, size, colour, taste and earliness of fruits thereby enhancing their market appeal, improve input use efficiency of NPK fertilizers and water. They provide disease resistance, thereby reducing dependence on plant protection chemicals, increase the post-harvest life of horticultural produce thereby avoiding wastage prevent physiological disorders and increase marketable yield.
