Abstract
A study was undertaken to examine the entitled âEffect of micro-nutrients, PGRs, and fungicide on physical and yield appearance quality of Aonla (Phyllanthus emblica G.) in cv. NA-10.â was carried out during the year 2024-2025 to 2025-26 at Main Experimental Station, Department of Fruit Science, College of Horticulture & Forestry, Acharya Narendra Deva University of Agriculture & Technology, Kumarganj, Ayodhya, Uttar Pradesh, India. To study the various physico-chemical properties, the experiment was laid out in a randomized block design (RBD) with (16) treatments and (03) replications. The experiment consists of 16 treatments including T1-Cow urine@30%, T2- HBR@5 PPM, T3-Azoxystrobin 23 SC@0.1%, T4-Calcium chloride@1%, T5-Borax@ 30g, T6-Cow urine x HBR@30 % x @5 PPM, T7-Cow urine x Azoxystrobin 23 SC@30 % x @0.1%, T8-Cow urine x Calcium chloride@30% x @1 %,T9-Cow urine x Borax@30%x@30g, T10-HBR x Azoxystrobin 23 SC@5 PPM x @0.1 %,T11-HBR x Calcium chloride@5 PPMx@1%,T12 HBRxBorax@5PPMx@30g, T13-Azoxystrobin 23 SC x Calcium chloride@0.1 % x @1 %,T14-Azoxystrobin 23SC x Borax@0.1 % x @ 30g, T15-Calcium chloride (CaCl2) x Borax@1 % x @ 30g, T16-Control (water spray). Results of two years of investigation revealed that spray of T11-HBR x Calcium chloride@5 PPM x @1 % was the best to increase plant height (9.25m) followed by T10-HBR x Azoxystrobin 23 SC @5 PPM x @0.1 %, which consequently resulted in the highest Stem girth (99.52cm), Canopy spread (5.22m), fruit weight (552.3g), TSS (8.960Brix) and ascorbic acid (560.39 mg/l00g), respectively, against (521.83mg /l00g), in the control. Fruit quality with regard to plant height, stem girth, canopy spread, fruit weight, and content was better in all the treated plants compared to the control.
