Study the Effect of Foliar Spray of Different Chemicals on Flowering and Fruiting in Mango (Mangifera indica L.) cv. Dashehari

Abstract

The current study was conducted during the year 2022-23 at Horticulture Farm, Bharregaon under Pt. K.L.S. College of Horticulture and Research Station, Rajnandgaon, (C.G.), during the period from first fortnight of October 2022 and November 2022. The experiment was laid out in randomized block design and replicated thrice with a total of 11 treatment where urea at 1.5%, 2% and 2.5%, KNO3 at 1.5%, 2% and 2.5%, Ethephon at 250 mg, SOP at 0.5%, 1% and 1.5% and control (spray in water).The present experiment revealed that the treatment T6 (KNO3 @ 2.5 %) exhibited better performance in relation to vegetative and growth parameters like minimum vegetative shoots per terminal (0.62), maximum of flowering shoots per terminal (0.98), minimum vegetative shoots  (7.64%), maximum flowering shoots (91.55%) and minimum days for full bloom (19.11 days), maximum panicle length (44.39 cm) yield parameters like highest weight of fruits (265.11g), highest length of fruits (11.18 cm), maximum  diameter of fruits (7.43 cm), maximum number of fruits per panicle (13.80 cm), Higher number of fruits per tree (294.50) and maximum fruit yield per tree (78.76 kg/tree) and quality parameters like maximum total soluble solids (19.89 0Brix), minimum acidity (0.16%), total sugar (13.61 %), reducing sugar (10.41%) and non-reducing sugar (3.12%). Hence, the treatment T6 (KNO3 @ 2.5%) may be recommended for foliar spray for improvement of vegetative growth, fruiting, quality and yield parameters of mango cv. Dashehari.
