Field trials on organic waste materials (OWMs) namely castor meal, activated sludge cake, compost, and effluent of biogas production from swine waste, as N-source for baby corn were conducted in Kamphaeng Saen soil. The results indicated that all OWMs could produce corn yield, in terms of numbers of total and marketable ears (4-13 cm long), and total N in ear and straw as high as chemical fertilizer (IF) 15 kgN/rai could. However, large-size marketable ears (10-13 cm) were found to be higher in th IF than those in the OWMs.
