Abstract:

Colocasia [Colocasia esculenta var. antiquorum (L.) schott.], which is also known as Taro, Arvi, Katchu and eddode belongs to the family Aracea is an important edible aroid. Africa ranks first in area and production of colocasia and in India colocasia is favourite among Gujarat, Konkan region of Maharashtra and several other parts of south India. The corm and cormels are the major economic parts of Arvi. Corms of colocasia are rich in carbohydrate and protein and nearly one and half time more nutritious than potato. Plant growth regulators are the chemical compounds which have given favourable impact on growth, yield and quality of crops. Though, agronomical practices for taro has been standardized and there is always demand for enhancing its growth from the growers. Hence, the present investigation has been carried out in the the Horticulture Research unit, Department of Horticulture, Faculty of Agriculture, Birsa Agricultural University, Kanke, Ranchi during Kharif season of 2017, where eleven treatments were used namely T1- Naphthalene acetic acid (25 ppm), T2- Naphthalene acetic acid (50 ppm), T3- Indole Acetic Acid (25 ppm), T4- Indole Acetic Acid (50 ppm), T5- Maleic hydrazide (50 ppm), T6- Maleic hydrazide (100 ppm), T7- Gibberellic acid (100 ppm), T8- Gibberellic acid (200 ppm), T9- Ethrel (75 ppm), T10- Ethrel (150 ppm) and T11- Control (water spray only) to find out increment in growth of taro by means of application of growth regulators at the time of 45 days after planting and 105 days after planting on the most accepted variety of taro, Muktakeshi in the state of Jharkhand. Among the eleven treatments used GA3 at the concentration of 200 ppm was found to record maximum growth parameters in cultivation of taro.
