Nutrient uptake by tomatoes 'Dominador' and 'Serato' grown in São Paulo State, Brazil
Plant nutrition and fertilization among other growing tools, are fundamental for the success of any agricultural activity. With the constant release of new genetic material with resistance to pest and diseases, adapted to specific climatic conditions, which use natural resources as light, water and nutrients more efficiently and yield better, existing fertilizer recommendations may need to be updated. Thus new technical information needs to be generated to support tomato production decisions. Therefore, the objective of the present study was to characterize plant growth, nutrient content and nutrient uptake of tomato 'Dominador' and 'Serato' during growth. The experiments for each hybrid were independent but carried out simultaneously. A completely randomized block design was used with four replications. The treatments were evaluations dates that happened every 14 days from transplant until 154 days after transplant. Plants were had two stems and eight vines per stem. 'Dominador' and 'Serato' yielded 9.9 and 11.9 kg plant-1. Total nutrient uptake, at 154 DAT for 'Dominador' was: K (371.9 kg ha-1) > N (235.9 kg ha-1) > Ca (153.3 kg ha-1) > S (68.0 kg ha-1) > Mg (41.3 kg ha-1) > P (30.7 kg ha-1) > Cu (1.6 kg ha-1) > Mn (1.2 kg ha-1) > Fe (1.0 kg ha-1) > Zn (0.5 kg ha-1) > B (0.3 kg ha-1). For 'Serato' nutrient uptake was: K (440.0 kg ha-1) > N (263.9 kg ha-1) > Ca (112.0 kg ha-1) > S (53.3 kg ha-1) > Mg (35.9 kg ha-1) > P (34.7 kg ha-1) > Cu (1.6 kg ha-1) > Mn (1.0 kg ha-1) > Fe (0.7 kg ha-1) > Zn (0.4 kg ha-1) > B (0.2 kg ha-1).
