Influence of Growth Regulators and Botanicals on Flowering, Fruit Set and Yield Attributes in Acid Lime (Citrus aurantifolia Swingle)

A field experiment on “Studies on enhancement of yield and quality in acid lime (Citrus aurantifolia Swingle)” was conducted at south farm, Vanavarayar Institute of Agriculture, Manakkadavu, Pollachi Tamil Nadu during 2014–2015. The experiment was laid out in a Randomized Block Design with nine treatments and three replications. Acid lime (Citrus aurantifolia swingle) is an important commercial species of citrus considered to be indigenous to India, and is extensively cultivated in almost all states of India under tropical and subtropical climatic conditions. In the present investigation, the T₃-Panchakavya @ 5% was recorded the highest number of flowers per shoot (9.30) and number of fruit set per shoot (7.70) followed by T₁-IAA @ 50 ppm was registered the number of flowers per shoot (8.35). The highest number of fruits per tree was observed in T₃-Panchakavya @ 5% (380.80) followed by T₁-IAA @ 50 ppm (350.30). The highest mean fruit weight was observed in T₃-Panchakavya @ 5% (53.60) followed by T₁-IAA @ 50 ppm (50.40). The treatment T₃-Panchakavya @ 5% was recorded the highest per tree yield (20.41 kg) followed by T₁-IAA @ 50 ppm (17.65).
