A field experiment was conducted at south farm, of Vanavarayar Institute of Agriculture, Manakkadavu, Pollachi, Tamil Nadu. 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 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). the highest fruit length was noticed in T₃- Panchakavya - 5% (6.50 cm) followed by T₁- IAA - 50 ppm (5.53 cm), the highest fruit girth was noticed in T₃- Panchakavya - 5% (6.86 cm) and also the highest fruit volume was recorded in T₃- Panchakavya - 5% (51.20 ml) followed by T₁- IAA -50 ppm (48.85 ml). In this investigation, the highest Juice content (ml/100 g) was noticed in T₃- Panchakavya - 5% (55.0 ml), the highest ascorbic acid content was recorded in T₃- Panchakavya - 5% (35.65 mg/100 g) and the highest acidity was recorded in T₄- Vemivash – 5 ml (7.25%).
