Other claims from this paper (9)
- Intervention effect Plant height and dry matter of tomato increased with increasing N fertigation rates.
- Intervention effect Stem diameter growth differed little among the N fertigation treatments.
- Intervention effect Tomato yield increased with a larger number of marketable fruits under N fertigation treatments.
- Intervention effect Fruit yield was maximized in the NF 80 treatment (176 kg N per ha).
- Intervention effect Dry matter productivity and nitrogen uptake were significantly increased with increasing N fertigation rates.
- Intervention effect The ratio of nitrogen distributed to fruits was 3.7 to 21.7% higher in N fertigation treatments than in the control.
- Intervention effect Apparent N recovery was significantly higher under N fertigation (71.8 to 102.3%) than under conventional N treatment (45%).
- Intervention effect Water use efficiency was significantly increased by the fertigation system, with a maximum of 361 kg/ha per cm in NF 80.
- Recommendation N fertigation was effective for increasing tomato productivity and nutrient efficiency, allowing a 20% reduction of N fertilization.
