ABSTRACT
The experiment was conducted during rabi season 2015-16 at Rajasthan College of Agriculture, MPUAT, Udaipur to evaluate the impact of irrigation and fertigation scheduling through drip irrigation in tomato (Lycopersicon esculentum Mill.). The experiment was laid out in split plot design with three replications and fifteen fertigation treatment combinations. The treatments include three levels of irrigation water viz., 100% (I1), 75% (I2) and 50% PE (I3) through drip and five levels of fertilizations through fertigation viz., 100% RDF (F1), 75% RDF (F2), 75% RDF + 2 foliar spray of 1% urea phosphate (F3), 50% RDF (F4) and 50% RDF + 2 foliar spray of 1% urea phosphate (F5). Drip irrigation at 75% PE (I2) + 75% RDF through fertigation + 2 foliar spray of 1% urea phosphate (F3) significantly enhanced plant height (67.43 cm), number of branches (12.33), average fruit weight (98.62 g), average fruit yield per plant (3.49 kg), fruit yield (201.25 q/ha), net return (` 220115.43) and benefit cost ratio (2.40). Quality characteristics like, fruit TSS, total sugar and reducing sugar also exhibit higher values (6.25 oBrix, 3.969 and 3.03 per cent respectively) with the same treatment combination. The highest water use efficiency i.e. 26.37 ka/ha-cm was recorded under I3F3 treatment and fertilizer use efficiency with drip irrigation upto 75% PE and under F5 treatment (157.11, 241.01 and 361.52 kg/kg NPK, respectively).
Key words :
Drip irrigation, Fertigation, Fertilizer use efficiency, Quality characters, Tomato, Water use efficiency.
