The guava botanically Psidium guajava belongs to family of myrtaceae. Guava was considerate to be one of the most exquisite and nutritionally valuable remunerative crop. It was originated in tropical America. The present investigation was conducted on “Effect of pruning and drip fertigation on growth parameters of Guava (Psidium guajava L.) cv. Sardar” at Farmers Field, Devathanapatti, Theni (Dt), Tamil Nadu. The field experiment was laid out in Factorial Randomized Block Design (FRBD) replicated thrice with two factors (Factor 1- Pruning, Factor 2- Fertigation), i.e., different pruning levels viz., P0 - Without pruning, P1 - Light pruning (removal of past season growth up to 15 cm), P2 - Moderate pruning (removal of past season growth up to 30 cm) and drip fertigation levels viz., F0 - 100 per cent recommended dose of fertilizer (RDF) as soil application and irrigation, F1 - 125 per cent RDF through fertigation, F2 - 100 per cent RDF through fertigation, F3 - 75 per cent RDF through fertigation, F4 - 50 per cent RDF through fertigation. The results of the investigation revealed that the morphological characters were significantly influenced by different pruning levels and drip fertigation treatments. Among the different pruning levels, P2 - moderate pruning (removal of past season growth up to 30 cm) increased the tree height, tree spread, fresh weight of pruned branches and number of new shoots emerged from pruned branches and shoot length resulting with earlier flowering in rainy season.
