Evaluation of Aonla Varieties Under Semi-Arid Conditions of Haryana

Abstract

The farmers or orchardist are trying different varieties/germplasm for growing as a commercial orchard without having knowledge about the performance of these varieties/germplasm. The experiment on varietal evaluation of on aonla comprising of nine promising cultivars (NA 6, NA 7, NA 10, NA 20, Krishna, BSR 1, Gujarat 1, Chakaiya and CHES 1) released from the different parts of the country was carried out to study the variation among different varieties on qualitative as well as quantitative basis and observed the performance of growth, physicochemical characters and yield during 2017-18, 2018-19, 2019-20 under semi-arid conditions to recommend the suitable variety. Plant shape was observed as spreading (CHES 1, Chakaiya, Krishna, NA 6, NA 7, NA 10, BSR 1); drooping (NA 20) and upright (G1) in different cultivars of aonla. The range of variability among different parameters such as plant height (4.90-6.70 m), plant spread-EW (4.47- 7.15 m), plant spread-NS (4.44-7.53 m) , stem girth (46.45-95.37 cm), plant volume (86.8-283.9 m3 ), plant canopy area (15.59-42.35 m2 ), total soluble solids,TSS (9.17-18.32 °B), acidity (1.92-2.63%), TSS : acidity ratio (4.09-7.71), ascorbic acid (323-567 mg/100 g pulp), fruit weight (5.89-55.43 g), fruit length (1.87-3.33 cm), fruit breadth (2.28-3.70 cm), yield (36-102 kg/plant and 10.00-28.34 MT/ha). Fruit shape was observed as flattened round (CHES 1, Chakaiya, NA 6, NA 10, G 1, BSR 1), triangular (Krishna), oval (NA 7) and round (NA 20). Free base (cavity at stem end) was observed as absent (CHES 1), shallow (Chakaiya, NA 6, NA 20, G 1), deep (Krishna), flat (NA 7, NA 10, BSR 1) and fruit apex was observed as flat (CHES 1, Chakaiya, Krishna, NA 7, NA 10, NA 20), papillate(NA 6, BSR 1), depressed (G 1).
