Guava (Psidium guajava L.), is one of the most important fruit crops cultivated widely in tropical region of the world and considered as ‘poor man’s apple’ or ‘the apple of tropics’ due to its low cost of production and high nutritional value. Pruning is one of the most ancient horticultural practices which regulate the tree size and shape to achieve a desired architecture of the canopy and also to reduce the vegetative growth by removing unproductive branches of the tree. Guava is an evergreen tropical fruit crop and rarely pruned in our country to regulate the canopy for better yield and quality of fruits despite that guava responds to pruning. Fertigation (application of fertilizer solution with drip irrigation) has the potential for the right combination of water and nutrient which make it available at the root zone, satisfying the plant requirements. These inputs are the key factors for high yield and quality. Fertigation saves fertilizer as it permits applied fertilizer in required quantities at a time matching with the plants nutrient requirement. Besides, it is considered as eco-friendly which avoids leaching and also saves atmospheric pollution.
