Utjecaj koncentracije dušika i cijepljenja na vegetativna i generativna svojstva rajčice
The present study aimed to determine the effect of nitrogen (N) rate reduction in nutrient solution and grafting on the vegetative and generative traits of tomato cv. ‘Belle F1’. Plants, nongrafted or grafted onto the rootstock Arnold, were planted into rockwool slabs and then treated with three rates of N: 75, 140 and 205 mgL-1. Two formed stems (main and lateral shoots) and five inflorescences were tomato cultivation characteristics. Plants treated with 140 mgL-1 N were higher and had more leaves than plants grown at 205 mgL-1 N. The leaf number of the lateral shoot was greater on the grafted than on non-grafted plants. The stem diameter in grafted plants (1.29 cm) was also higher compared with non-grafted plants (1.06 cm). The value of the chlorophyll concentration index (CCI) was influenced by N and grafting. An increase of N rate affected the increase of CCI in non-grafted plants, while in the grafted plants N rate did not affect CCI. The appearance of the first inflorescence was earlier recorded on non-grafted compared with grafted plants. Plants treated with 75 mgL-1 N had higher early yield (1.25 t / 0.1 ha) compared with two other N treatments. However, the fruit weight (231 g) on 75 mgL-1 N was lower compared with plants treated with 140 mgL-1 N (316 g). Grafting influenced on tomato vegetative growth, but not on yield components. The use of 75 mgL-1 N provided a higher early yield, while total yield increased by almost 20% using 140 mgL-1 N.
