The trial was conducted under field conditions to study the effect of fertigation on yield, quality, water use and economics of ratoon banana during 2013-14 at Interfaculty Department of Irrigation Water Management, MPKV Rahuri. There were nine treatments replicated thrice in randomized block design. The results indicated that 100% RDF through monoammonium phosphate (12:61:00) recorded significantly higher yield (82.35 t ha-1) and it was at par with fertigation @ 80% RDF applied through special grade fertilizer (9:5:33) and balanced N and P2O5 (T6) and fertigation @ 80% RDF applied through monoammonium phosphate (12:61:00). The treatment T6 saved 20 per cent fertilizer and had 12.71% increases in yield over drip irrigation with 100% RD of conventional fertilizer application method (T8). Fertigation with water soluble fertilizers had a positive effect on pulp: peel ratio and TSS of banana as compared to conventional method (T8). The higher net monetary returns and water productivity was observed in fertigation treatment T2 to tune of Rs. 4,27,798 ha-1 and Rs. 434 per cm respectively.
