Abstract

An experiment was carried out to study the impact of drip fertigation in tomato crop at RCA, MPUAT, Udaipur during rabi season 2015-16 in split plot designed with three irrigation schedules [100 (I1), 75 (I2) and 50% PE (I3) through drip] and five fertilization schedules [100% RDF (F1), 75% RDF (F2), 75% RDF + 2 foliar spray of 1% urea phosphate (F3), 50% RDF (F4), 50% RDF + 2 foliar spray of 1% urea phosphate (F5)]. Higher number of nodes per plant (21.20 and 19.89) and yield (169.03 and 186.38 q/ha) were registered with treatments receiving drip irrigation at 75% PE and 75% RDF through fertigation + 2 foliar spray of 1% urea phosphate, respectively. Quality characteristics were enhanced with combined use of I2F3 treatment. The highest water use efficiency i.e. 26.37 ka/ha-cm was recorded under I3F3 treatment and fertilizer use efficiency with I2F5 treatment combination (165.78, 254.31 and 381.46 kg/kg NPK, respectively).
