Drip fertigation is known to enhance the growth and productivity of various crops. Since maize is a heavy feeder of nutrients and water, thus, proper management of these resources is the key to successful growth of maize. Keeping this in view, a field experiment was conducted at Zonal Agricultural Research Station, UAS, GKVK, Bangalore, during kharif season of 2012, to study the effect of drip irrigation and fertigation with different levels and sources of fertilizers on productivity and economics of maize. The experiment consisted of ten treatments laid out in Randomized Complete Block Design with three replications. The experimental results indicated that drip fertigation with 125 % RDF through water soluble fertilizers produced the maximum grain yield (11.9 t ha-1), which was on par with drip fertigation with 100 % RDF through water soluble fertilizers (11.3 t ha-1). The lowest grain yield was recorded with surface irrigation with 100 % RDF through normal fertilizers (7.9 t ha-1). Decrease in RDF to 50 % in drip fertigation system has resulted in lower grain yields with both water soluble and normal fertilizers. However, highest net returns and B: C ratio was obtained with drip fertigation with 125 % RDF through NF (Rs 92734 ha-1 and 3.46, respectively) which was on par with 100 % RDF through NF (Rs 90614 ha-1 and 3.46, respectively).
