It is a perennial herbaceous plant which is grown in tropical and subtropical regions. It requires warm season for its growth. It is commercially grown because of its consumption of sweet and starchy tubers. Arvi is also known as Taro and the Taro roots are also known as “eddo”, “dasheen” and “kalo”. The plant mainly attains the height of 1-2m. They have light green color leaves which are elongated and heart shaped.

Arvi is planted in variety of soil ranging from sandy to loamy soil. But the best results it gives when grown in sandy loam or loamy soils having high organic matter. Avoid cultivation in soil having poor drainage system. Soil which lacks in fertility and moisture results in low quality corm yield.

For Arvi plantation, the land should be well prepared. To bring the soil to the fine tilth, before sowing land must be ploughed 2-3 times followed by planking’s. The field should be kept weed-free.
Time of Sowing
For optimum yield, tubers should be sown in nursery beds in the first fortnight of February under Punjab conditions
Use row to row spacing of 60 x 15 cm or 45 x 20 cm.
Use depth of 6-7.5 cm for tuber planting.
Method of sowing
The corms are sown manually, deep in the soil. Dibbling method is used for sowing corms. Beside this its sowing is also done with potato like machine used for sowing
Use 300-400 kg of tubers in per acre land.
For seed treatment dip the tubers in 2% solution of Bavistin for 30 minutes. It protects the tubers from the soil borne diseases.
Fertilizer Requirement (kg/acre)
Apply well rotten FYM (Farm Yard Manure) @5-7tonnes/acre before sowing. Along with FYM apply fertilizer dose in terms of Urea @90kg/acre, SSP @125kg/acre and MOP @35kg/acre.
Full dose of K2O and P2O5 is applied at the time of planting. Nitrogen dose is applied in 2 splits i.e. first at the time of sowing and remaining half should be applied at the time of hoeing and weeding.
To make the field weed free, 1-2 hoeing’s and earthing up should be done after each hoeing.
Pre-requisite irrigation is necessary for good yield of crop. In summers, irrigation is given at the interval of 3-4 days and in rainy season, no irrigation required but sometimes lifesaving irrigation is necessary. Arvi requires constant irrigation for regular sprouting therefore immediate irrigation is required after sowing. Keep the field wet till seedling germination.
