Some investigations with regard to the effect of nitrogen on the storage qualities of celery.

missing page 6 in original document[...]The yield of celery growing on muck soils was not increased by increasing the nitrogen content of the fertilizer from 0 to 14 per cent, thephosphorus and potash content remaining constant, 8 and 10 per cent respectively. Furthermore, there, was no change in size of plant as measured by weight, diameter and height ofplants.With regard to wilting in cold storage no significant difference was noted between lots of celery from different nitrogen plots. Dry matterdeterminations likewise showed no significant difference between plots.Celery from the different nitrogen plots showed similar physical storage qualities, pithiness, breakdown of leaves and petioles,etc.Varying the nitrogen content of the fertilizer mixture did not change the total nitrogen content of the plant as no significant difference existingin quantities of total nitrogen in plants from different plots is determined by the Kjeldahl method. Only slight decreases were noted in the plantsthroughout the storage period. This decrease was uniform in celery from all plots throughout the storage period.Hexose sugars increased gradually until the end of the storage period, while sucrose sugars showed a slight decrease.It was concluded that the period of economical storage was 90 to 100 days under the conditions of this experiment.A carefully planned fertilizer experiment has been presented for consideration
