Sažetak
Grafting and nitrogen (rates: 75, 140, and 205 mg/l N ; and ratios: 92:8, 85:15 and 70:30 of NO3-:NH4+) effect on yield and pests populations was studied in hydroponics tomato during 2012 and 2013. Grafting did not affect marketable yield but affected populations of Bemisia tabaci and Tuta absoluta, in both experiments. The lower number of B. tabaci nymphs was recorded on grafted (rootstocks cv. Arnold or He-Man) than on self or non-grafted plants. The number of T. absoluta mines was the lowest on plants grafted on cv. Arnold. The lowest fruit mass was recorded on plants fertigated with 75 mg/l N in 2012. In 2013, number of fruits and total yield was higher on plants supplied with 8% NH4+ than on plants supplied with 30% NH4+ in nutrient solution. B. tabaci nymphs were the most numerous on plants grown at 205 mg/l N in 2012. The lowest nymphs population inhabited plants supplied with 30% NH4+ in 2013. T. absoluta infestation was higher on plants grown at 140 and 205 mg/l N in 2012 as on plants supplied with 15% NH4+ in 2013. Results could be applied in sustainable pests management.
