Study was conducted at the Horticultural Experimental Farm, Birauli, Rajendra Agricultural University, Pusa durlng 1998-1999 to find out effect of the different doses of fertilizer under fertigation on phenological characteristics such as plant height, plant girth, root development; on fruiting time and bunch charactenstics as well as saving in fertilizer. The obtained results revealed that, treatment T1 with 100% of recommended dose of fertilizer (RDF), NPK under drip fertigation gave highest values of plant height, plant girth and average number of leaves followed by treatment T2 with 80 % of RDF. Also, this treatment caused earlier bunch shooting. bunch harvesting as well as fruiting time. The highest bunch weight. number of hands1 bunch and number of fingerslbunch with best finger quality (weight, length and diameter) were recorded In T1. Lower values were obtained in treatment with T3 with 60% RDF in drip irrigated treamnent and T4 with 100% of RDF under traditional method of fertilizer application. Maximum yield of banana was obtained in treatment TI (95.2 t.ha.') followed by T, (87.6 t-ha-'), T, (76.4 t.ha-') and T, (73.1 t.ha-I). The treatment TI and T, gave 24.5% and 14.6% more yield. respectively in comparison to control treatment. The result indicated that application of only 65% of RDF can give the yield at par with conventional cultivation. The water and fertilizer use efficiency was about 25% higher for drip fertigated plot in comparison to check basin method of irrigation and fertilizer application through soil manipulation method.
