By adopting mentioned practices, one can achieve a high yield of Elephant Foot Yam
Elephant foot yam is traditionally cultivated on commercial scales in the states of Andhra Pradesh, Tamil Nadu, Kerala and West Bengal. Elephant foot yam is high in vitamin B6, vitamin C and vitamin A. It has Omega 3 fatty acids which are known to increase the good cholesterol levels in blood.
Yam is grown in wet humid regions. Well drained, fertile, Sandy loam soil is most suited for its cultivation. Gajendra, Shripadam, Kusum and Santragachi are most popular varieties. Around 2-3 deep ploughing is required for good land preparation. Cut tubers or small tubers are used as seed. Treat the seeds with tricoderma or with biogas celery for 8-10 hours. Planting is done 20-25cm deep in pits maintaining a spacing of 1m×1m. The spacing can vary to 60cm depending on the variety. A seed rate of 100 quintal per hectare is enough whereas this rate may vary according to the size and weight of the variety. Planting in rainfed areas is usually done with the onset of monsoon while in irrigated areas planting can be done in months of Februay-March. Application of 100kg nitrogen, 60kg phosphate and 80 kg potash with 10-20 tonnes per hectare of compost is recommended. Nitrogen and Potash should be applied in two splits, half with the full dose of phosphate as basal and remaining half after 30 days of sowing. Weeds are controlled by timely hoeing. First irrigation should be provided at the time of sowing and after that according to the requirement. Water stagnation should not be allowed at any stage of crop growth. There is very low risk of any pests and diseases; however, fertigation can be done as a precaution. Harvesting is done after 7-8 months of planting, when the leaves turns yellow and starts shedding. Stop irrigation 20 days prior to harvesting. Yield usually depends upon the variety but on an average 30-60 tonnes per hectare can be achieved.
By adopting above mentioned practices, one can achieve a high yield of elephant foot yam.
