An experiment was conducted at the Regional Horticultural Research Station, Navsari Agricultural University, Navsari to study the Regulation of flowering in guava (Psidium guajava L.) cv. Allahabad Safeda. The experiment included eight treatments, consisting of NAA at 600, 800 and 1000 mg ppm, urea at 10, 15 and 20 per cent, pruning and water sprayed control. The experiment was laid out in Randomized Block Design with three replications. The results revealed that the foliar application urea at 20 per cent induced early leaf drop, early new leaf emergence and early 50 per cent bloom as compared to other treatments. The leaf drop was also the maximum in above treatment. The higher fruit set percentage was recorded in the guava tree sprayed with NAA at 600 ppm. The higher yield of guava was obtained when the guava tree was sprayed with 15 per cent urea. The higher yield was contributed by the bigger size fruits of guava having higher fruit weight. However, the maximum number of fruits was harvested from the guava tree receiving foliar spray of urea at 10 per cent. The harvesting of guava fruits was delayed and lasted for longer period under the treatment of foliar spray of NAA at 1000 ppm. The foliar spray of urea at 20 per cent produced the better quality fruits in respect of TSS, total sugar, non-reducing sugar, reducing sugar and acidity. While the foliar spray of 15 per cent urea produced the guava fruits with higher ascorbic acid content.
