The maximum yield (21.67 t•ha-1 and 20.85 t•ha-1) was obtained with fertigation level F1 (80% of R.D) and irrigation level I2 (0.3PE). The yield was 44.28% and 39% higher in fertigation level F1 and irrigation level I2 as compared to conventional method of irrigation. The individual effect of fertigation and irrigation levels showed significant effect on the yield but the interaction effect between fertigation and irrigation levels was found to be non-significant. The maximum water use efficiency (WUE) of 11.6 t•ha-1-mm and 10.9 t•ha-1-mm was recorded with I1 and F1 while maximum fertilizer use efficiency (FUE) of 135.10 was recorded with F1. The total quantity of water applied through drip irrigation and conventional method of irrigation was 16.35 cm and 48.00 cm respectively, indicating 65.93% saving of water in drip irrigation system over conventional method of irrigation. The B:C ratio 1.94 was found maximum in treatment combination I2 F1. Maksimalni prinos (21.67 t•ha-1 i 20.85 t•ha-1) je postignut sa nivoom fertirigacije F1 (80% R.D) i nivoom navodnjavanja I2 (0.3PE). Prinos je bio 44.28% i 39% viši sa nivoom fertirigacije F1 i nivoom navodnjavanja I2 u poređenju sa konvencionalnom metodom navodnjavanja. Pojedinačni efekti nivoa fertirigacije i navodnjavanja pokazali su značajan uticaj na prinos, ali efekat interakcije nivoa fertirigacije i navodnjavanja nije bio značajan. Maksimalna efikasnost navodnjavanja (WUE) od 11.6 t•ha-1-mm i 10.9 t•ha-1-mm je postignuta sa I1 i F1 dok je maksimalna efikasnost đubrenja (FUE) od 135.10 postignuta sa F1. Ukupna količina vode koja je upotrebljena za navodnjavanje kap po kap i konvencionalni metod navodnjavanja bila je 16.35 cm i 48.00 cm, redom, pokazujući uštedu vode od 65.93% pri navodnjavanju kap po kap u odnosu na konvencionalni metod navodnjavanja. Odnos B:C od 1.94 je bio maksimalan u tretmanu kombinacijom nivoa I2 F1.
