Abstract:
Experiment was carried out to study the effect of growth regulators, micronutrients and chemicals on growth, yield and quality of acid lime (Citrus aurantifolia Swingle) under HDP system”. The experiment comprised of 13 treatments consisting of plant growth regulators (GA₃ and NAA), micronutrients (FeSO₄ and Boron) and chemicals (KNO₃ and Salicylic acid) on fruit yield and quality of acid lime. Significant results were obtained in treatment GA₃100 ppm + KNO₃ 2% + Salicylic acid 200 ppm + FeSo₄ 1% + Boron 1% (T₁₁) for days to flower bud initiation (38.5 days), days to 50% flowering (49.0 days), fruit setting percentage (87.1%), fruit diameter at 120 days (4.59 cm), average fruit volume at harvest (41.8 cc), total soluble solid (8.93 ⁰Brix), number of fruits per plant (974.2), and average yield per tree (38.3 kg). Treatments which included micronutrients showed good results in terms of quality and quantity attributes of fruits.
