Effect of Plant Growth Regulators and Chemicals on Physico-chemical Parameters of Acid Lime (Citrus aurantifolia Swingle). cv. Vikram

The present investigation was carried out at Experimental area, College of Agriculture, Gwalior (M.P.) during 2018-19 and 2019-20. The experiment aimed at finding out the effect of growth regulators and chemicals on physico-chemical parameters and yield of acid lime. T₁₀ (GA₃60 ppm + Cycocel 2000 ppm +Thiourea 2%) was found to be significantly superior to rest of the treatments under study but was reported to be at par with T₉ (GA₃60 ppm + Cycocel 2000 ppm + Thiourea 1%) for all the parameters like fruit volume (50.44, 50.77 and 50.61 ml), specific gravity (1.10, 1.11 and 1.10 g/cc), fruit length (5.13, 5.26 and 5.19 cm), fruit diameter (4.85, 4.91 and 4.88 cm), pulp thickness (45.27, 46.07 and 45.67 mm), minimum peel thickness (1.63, 1.50 and 1.57 mm), juice (43.85, 43.80 and 43.83%), TSS (7.69, 7.80 and 7.75%), acidity (7.81, 7.86 and 7.83%), number of seeds per fruit (6.67, 6.33 and 6.50), seed weight (1.20, 1.14 and 1.17 g) and yield per ha (410.29, 398.37 and 404.39 q) during first, second and pooled year respectively).
