Effect of spacing and potash levels on physical and chemical parameters of yam bean (Pachyrhizus erosus L.) tubers under Konkan agro-climatic conditions

Abstract

Yam bean is a plant which produces both starch and proteins in quite high level. Thus, yam bean can be used as an alternative source of starch with high protein content. A field research was conducted to study the effect of spacing and potash levels on physical and chemical parameters of Yam bean (Pachyrhizus erosus L.) tubers under agro-climatic conditions of Konkan region. The field experiment was carried out in Split Plot Design with three replications. There were two factors studied in experiment viz., a) four spacing levels and b) four potash levels. Effect of interaction on chemical parameters of yam bean tubers was significant except protein content of the tubers. Highest dry matter content (16.50%) was recorded in S4F2. Highest crude fibre (0.79%) was recorded in S1F2. S4F4 recorded highest starch content (6.53%) whereas S2F2 recorded highest moisture content of tubers (90.10%).
