Abstract

The aim of this study was to evaluate the effects of the foliar application of zinc (50 and 100 mg/L) and iron (100 and 200 mg/L) and their combination on vegetative, reproductive growth, fruit quality and yield of tomato plants as a laid out in completely randomized block design with four replications. The results showed that high Zn (100 mg/L) and Fe (200 mg/L) and their combination significantly promoted vegetative and reproductive growth. Foliar application of Zn (100 mg/L) + Fe (200 mg/L) resulted in the maximum plant height (124.14 cm), branches per plant (8.36), flowers per cluster (18.14), fruits per cluster (8), fruits per plant (90.14), fruit weight (95.14 g), chlorophyll content (22.14 SPAD) and yield (25.14 t ha–1). Fe and Zn alone or in combination had significant effect on leaves-NK content and nitrate reductase activity. The highest TSS (5.87 °Brix), TA (4 %), pH (2.61 %), fruit firmness (3.66 kg cm–2) and fruit lycopene content (2.25 mg/100 g) were observed when tomato plants treated with 100 mg/L Zn+200 mg/L Fe, thus it was

8 of 19 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
