S.K. Singh, Vijai Kishor Gupta

Abstract

A field experiment was conducted during summer season (March–July) of 1997 and 1998 to study the effect of bio, organic and inorganic source of nutrients on potato tuber yield. Application of farm yard manure (FYM) @ 15 t/ha significantly increased the growth, tuber yeild and net return of potato. Application of 100% N of recommended dose also boosted the growth and yield of potato. Application of FYM recorded the saving of 60 kg N/ha. Azotobacter proved effective in enhancing the growth and tuber yield of potato. Interaction effect of FYM, nitrogen and Azotobacter was significant. Highest tuber yield and net return was obtained with application of FYM @ 15 t/ha + Azotobacter + 100% recommended dose of nitrogen.
