Effect of pruning and drip fertigation on flowering character of Guava (Psidium guajava L.) cv. Lucknow 49

Abstract

An experiment was conducted to see the “Effect of pruning and drip fertigation on flowering character 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 flowering 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) resulting with earlier flowering in winter season compare to the rainy season.
