Abstract:

We evaluated tomato yield and fertilizer nitrogen (N) use efficiency under two watering systems and two N forms. Six treatments were used: hand watering (HW) with no fertilization (T1), dripping bucket irrigation (DBI) with no fertilization (T2), DBI with 200 kg of N15P15K15 + 100 kg of ordinary urea (OU) ha-1 (T3), HW with 200 kg of N15P15K15 + 100 kg of OU (T4), DBI with 200 kg of N15P15K15 + 100 kg of urea in the form of super granule (USG) (T5) and HW with 200 kg of N15P15K15 + 100 kg of USG (T6). Yield was responsive to fertilization, watering system and N form. OU increased yield by 72.40% under DBI (30.20 t ha-1) versus yield for HW. USG allowed yield increase of 172% for the DBI (33.28 t ha-1) in comparison with yield under HW. Yield under HW was 30% lower with USG (12.25 t ha-1) than with OU. Under DBI, yield was 10% superior when USG was used (33.28 t ha-1) over the yield with OU. The DBI system provided a better use of N than HW, with much greater N agronomic efficiency index with USG.
