The aim of this study was to evaluate the sprouting, yield and economics of elephant foot yam under the influence of different pre-planting treatments using organic and inorganic substances. The pre-planting treatment of minisetts with thiourea at 400 ppm resulted in maximum sprouting percentage (97.22%). This treatment also recorded highest corm yield (12.57 t ha-1) and showed maximum increase in corm yield (31.07%) over the control treatment. The economics over two years showed that among the different pre-planting treatments, the thiourea at 400 ppm stood as the best treatment which gave maximum net return of Rs. 91851 with a B: C ratio of 2.71 followed by thiourea at 300 ppm (net return Rs. 90651 and B: C ratio 2.69), thiourea at 200 ppm (net return Rs. 88951 and B: C ratio 2.66) and KNO3 at 250 ppm (net return Rs. 88021 and B: C ratio 2.66).

Abstract


The aim of this study was to evaluate the sprouting, yield and economics of elephant foot yam under the influence of different pre-planting treatments using organic and inorganic substances. The pre-planting treatment of minisetts with thiourea at 400 ppm resulted in maximum sprouting percentage (97.22%). This treatment also recorded highest corm yield (12.57 t ha-1) and showed maximum increase in corm yield (31.07%) over the control treatment. The economics over two years showed that among the different pre-planting treatments, the thiourea at 400 ppm stood as the best treatment which gave maximum net return of Rs. 91851 with a B: C ratio of 2.71 followed by thiourea at 300 ppm (net return Rs. 90651 and B: C ratio 2.69), thiourea at 200 ppm (net return Rs. 88951 and B: C ratio 2.66) and KNO3 at 250 ppm (net return Rs. 88021 and B: C ratio 2.66).
