Abstract
A 2-year (1990-92) field experiment was conducted in West Bengal, India, to study the optimum rates of N and K, and spacings for cut chrysanthemum (cv. Chandrama) production. Four N rates (0, 10, 20 and 30 g/msuperscript 2), 3 K2O rates (0, 10 and 20 g/msuperscript 2) and 3 spacings (40 x 40, 40 x 30 and 30 x 30 cm) were tested in a randomized, factorial design. N at 30 g/msuperscript 2 and K at 20 g/msuperscript 2 appreciably improved the vegetative and flowering attributes of chrysanthemum. Closer spacing (30 x 30 cm) also increased plant height, stalk length, and numbers of flowers per unit area.
