A field study was conducted for performance evaluation of drip fertigation system on young lemon plants (Kagzi lemon).Nitrogen(240 g N plant-1)in the form of urea was applied in various split doses(4,6,8,and 10 nos.)through drip irrigation system.Influences of drip fertigation were studied in terms of plant growth parameters(height,girth,canopy cover area),water application uniformity,fertlizer application efficiencies, leaf N status, and emitter's clogging.Observed N delivered near plants ranged from 55 to 76 per cent of total Nsupplied through drip system.Frequent applications of N(8 applications @30 g N plant-1)gave best fertilizer application efficiency,but on the other hand it considerably reduces the water application uniformity because of higher clogging of emitters.Plant leaf N contents varied between 0.616 to 4.883 per cent,under different sets of treatments.Results demonstrate that sustainable leaf N status could be achieved by more frequent N applications.
