Studies On The Effect Of Micronutrients In Acid Lime (Citrus aurantifolia Swingle) var. PKM-1

Acid lime (Citurs aurantifolia Swingle) belongs to the family Rutaceae and widely grown in tropical and subtropical regions of India. India is the largest producer of acid lime in the world. In India, Maharashtra, Andhra Pradesh, Tamil Nadu, Gujarat, Rajasthan and Bihar are grown in larger area. In Tamil Nadu, commercially cultivated in Tirunelveli, Tenkasi, Turicorin, Dindigul, Madurai, Theni, Virudhunagar and Perambalur districts. Fruits are being used for preparation of pickles and beverages. They are rich in vitamin C, minerals and salts. Micronutrients such as Zinc, Iron and boron play a vital role in acid lime for growth and development. With this background, the present experiment on studies on the effect of micronutrients in acid lime var. PKM-1 was conducted at Citrus Research Station (TNAU), Sankarankovil during 2020-21 to study the effect of micronutrients on growth, yield and quality of acid lime. Foliar application was given twice in a season viz., the first spray was given during peak flowering stage and next spray during fruit set stage on selected five trees for each treatment at farmer’s field. The trial was laid out in a randomized block design (RBD) with thirteen treatments and replicated thrice.
