Effect of Plant Growth Regulators and Chemicals on Yield of Acid Lime (Citrus Aurantifolia Swingle) During Hasta Bahar

A field experiment was conducted at All India Coordinated Research Project on Fruits, Department of Horticulture, Mahatma Phule Krishi Vidyapeeth, Rahuri during the years 2008–09 to 2012–13 to study the effect of plant growth regulators and chemicals on yield of acid lime (Citrus aurantifolia Swingle) in Hasta bahar with an objective to increase the yield of acid lime during summer. Application of GA₃(50 ppm) in June and Cycocel (1000 ppm) in September followed by KNO₃(1%) in October recorded significantly the maximum number of flowers per shoot (37.05), number of fruits per tree (307.06), fruit weight (40.28 g) and yield (11.86 kg/tree and 3.27 t/ha) which was followed by the application of GA3_=a=A(50 ppm) in June and Cycocel (1000 ppm) in September followed by KNO₃(2%) in October.
