GROWTH AND QUALITY OF CARNATIONS GROWN ON MINERAL WOOL |
| Author: | E. Kaukovirta |
| Abstract:
Carnation, cultivar 'Lena' was grown on mineral wool mats and on sphagnum peat over a one year growing period, and fertilized with two complete nutrient solutions in which the source of N was different. According to the results obtained from the two experiments, other forms of N in addition to NO3-N were necessary for feeding carnations grown on mineral wool. The development of plants was slower on mineral wool than on peat subsrate during the first weeks of the growing period. This, together with the effect of the feeding solution, affected the distribution of flower production as well. The effect of substrate on the quality of flowers was dependent on the nutrient solution used. | |
