ThesisItem Open Access Effect of NAA and Micronutrients on Flowering, Fruit Setting, Yield and Quality of Litchi (Litchi chinensis Sonn.) cv. Muzaffarpur(College of Horticulture and Forestry, Central Agricultural University, Pasighat, 2021-09-22) INDIRA DEVI, SANABAM; Singh S, Romen; Hazarika, B.N.Experimental results revealed that the imposition of different treatments had a significant effect on increasing flowering, fruit setting and improving the yield and quality of the fruits. Maximum increase in plant height (36.50 cm), canopy height (34.95 cm), volume of the canopy (68.70 m3), highest number of female flower/panicle (75.00), fruit setting %/panicle (26.25%), number of fruits at harvest stage/panicle (15.00), maximum yield/plant (24.00 kg), maximum TSS (18.75ºBrix), ascorbic acid (25.70 mg/100 g), total sugar (15.70%), reducing sugar (10.05%) with minimum titratable acidity (0.24%) were recorded in treatment T8 (NAA @ 25 ppm + 0.5% Borax + 0.5% Zinc sulphate) whereas, date of 50% flowering (1st March) i.e. early flowering, early fruit maturity (25th May), maximum fruit diameter (2.54 cm), fruit volume (18.40 cm3), fruit weight (20.60 g), aril weight (13.24 g), juice content (9.20 ml) with minimum fruit cracking%/plant (3.61%) were obtained in treatment T7 (NAA @ 20 ppm + 0.5% Borax + 0.5% Zinc sulphate). However, non-significant effect was found in stem girth, fruit length and shelf life of the fruits. Therefore, application of recommended dose of fertilizers (1200:500:600 g NPK/plant/year) along with foliar spray of NAA @ 25 ppm + 0.5% Borax + 0.5% Zinc sulphate thrice (first application after emergence of new flushes during November followed by second application at one month interval during December and third application after fruit setting during April) can be recommended to the litchi growers under foothills condition of Arunachal Pradesh to increase the yield and productivity.
