Impact of foliar application of growth regulators and micronutrients on yield and quality of acid lime (Citrus aurantifolia Swingle)

Abstract

The present study was carried out to study the effect of micronutrients and plant growth regulators on yield and quality of acid lime (Citrus aurantifolia Swingle) at Madhukampalayam village of Dharapuram block in Tamil Nadu during December 2019 to June 2020. The treatment consists of foliar application of growth regulators viz., NAA, GA3 and 2,4-D and micronutrients such as boric acid, FeSO4 and ZnSO4. The plant growth regulators and micronutrients are very much essential for growth and development of acid lime. The study denotes that yield, number of fruits per plant, fruit weight, fruit diameter, fruit circumference, fruit volume, juice content and ascorbic acid were found to be increased by application of NAA 30ppm+Boric acid (0.2%) and the number of seeds were found to be reduced by application of 2,4-D when compared to control.
