A field experiment was conducted during 2008-09 and 2009-10 at New Delhi, to study the effect of organic sources of nutrients on growth, yield and yield attributes of pop porn (Zea mays averta Sturt)-potato (Solanum tuberosum L.) cropping system. The experiment consisted of 24 treatment combinations with 8 treatments in pop corn [control, recommended dose of fertilizers (RDF) (120P25K35 kg/ha), farmyard manure equivalent to120 kg N/ ha (FYM120), leaf compost equivalent to 120 kg N/ha (LC120), vermicompost equivalent to 120 kg N/ha (VC120), farmyard manure equivalent to 90 kg N/ha (FYM90), leaf compost equivalent to 90 kg N/ha (LC90) and vermicompost equivalent to 90 kg N/ha (VC90)] and 3 treatments in potato crop [control, farmyard manure equivalent to 60 kg N/ha (FY60) and farmyard manure equivalent to 90 kg N/ha (FYM90)]. The application of RDF (N120P25K35 kg/ha) recorded significantly highest plant height, leaf-area index and dry matter with higher values of yield attributes, viz. cob length and girth, cobs/ha over the control. Application of vermicompost equivalent to 120 kg N/ha was the best source and remained at par with VC90, FYM120, FYM90 and N120P25K35 kg/ha for growth and yield attributes of pop corn. Similar trend in respect of grain and stover yield was also found. Due to residual fertility of FYM (equivalent to 120 kg N/ha) potato recorded the highest plant height, LAI, number of haulms and dy matter in haulms. Both FYM (equivalent to 90 kg/ha) and vermicompost (equivalent to 120 kg N/ha) exhibited the effects similar to FYM @ 120 kg N/ha. The yield and yield attributes of potato, viz. tubers/hill, fresh and dry weight of tubers, tuber yield and haulm yield also exhibited similar trend. Regarding direct effects of FYM, application of FYM equivalent to 90 kg N/ha in potato recorded the higher plant height, LAI, haulms/hill, dry matter in haulms; and yield and yield attributes compared to FYM equivalent 60 kg N/ha and control.
