Effect of Foliar Application of Micronutrients and PGR’s on Yield and Growth Characteristics of Guava (Psidium guajava L.) cv. Banarasi

An experiment was conducted in 12 year old plants field at Dharmapuri (Tamil Nadu) during the year 2019-20. To studies the effect of foliar application of micronutrients and PGR’s on yield and growth characteristics of guava (Psidium guajava L.) cv. Banarasi. The experiment was laid out Randomized Block Design with ten treatments and replicated thrice with a unit of one plant in each replication of a treatment. Different doses of (ZnSo4) @ 0.25%, 0.5% and 0.75%, Borax @ 0.2%, 0.4% and 0.6% and GA3 @ 50 ppm, 75ppm and 100ppm with control (water sprayed) were sprayed before flowering and after fruit set. The present study it can be concluded that the Borax 0.6% followed by 0.4% significantly increased the flowering per shoot (56.83), fruit set (65.4%), fruit retention (56.78%), fruit weight (142.5g), fruit length (6.43cm), fruit width (6.31cm) and fruit yield (65.13 kg/plant).
