The field experiments were conducted during consecutive seasons of 2010–2011 at the Research Farm of Water Technology Centre, Indian Agricultural Research Institute, New Delhi, India, to study the effect of drip fertigation and fertilizer application in furrow irrigation on yield of baby corn hybrid, HM-4. The recommended dose of fertilizers was applied in all the treatments. In drip irrigation, fertilizer solutions were applied through venture injector. However, broadcasting method was used for fertilizer application under furrow irrigation. Different treatments includes three fertigation frequencies (twice weekly, weekly and fortnightly), three dripper discharges at different systems operating pressures were the main treatments under drip fertigation and fertilizer application under furrow irrigation. Yield attributes of baby corn were significantly (P<0.05) affected by fertigation frequencies. Fertigation frequency schedule as twice weekly recorded significantly highest yields of baby corn (22.5 q/ha) and fodder (633.3 q/ha) with dripper discharge at system operating pressure of 1.0 kg/cm during second season. However, lowest yields of baby corn (10.7 q/ha) and fodder (413.0 q/ha) were recorded under fertilizer application in furrow irrigation during third season.
