Resumo
Although the information about nutritive solution for potted chrysanthemum is still incongruent, the objective of this work was to evaluate the effect of nutritive solutions in the development of Miramar chrysanthemum cultivated in pots at FCAV-UNESP, Jaboticabal-SP. The experiment had a randomized block design with split-plot evaluation and treatments corresponding to four nutritive solutions consisting of commercial fertilizers (S1, S2, S3, S4) evaluated at 0, 14, 28, 42, 56 and 70 days after rooting (DAE), with five replications. The plant height, leaf area, number of leaves, stem diameter, total dry matter mass of aerial part and roots; number and diameter of inflorescences, and physiological indexes of growth analysis were evaluated. The nutritive solutions did not interfere significantly in stem diameter, number and diameter of inflorescences and dry matter of roots, although S3 and S4 provided the highest plants, leaf area, number of leaves, total dry matter of aerial part. The physiological indexes showed that plants presented an accelerated growth from 14 to 28 DAE with S4 and S3 solutions and therefore they were considered the best solutions.
