Abstract

Effect of different amounts of NITROGENous fertilizer as Urea (0, 50, 100, 150, 200 and 250 kg N/ha) was studied on GROWTH, YIELD and NITRATE ACCUMULATION in CUCUMBER cv. Daminos. The experimental design was a complete randomized block with four replications. Several plant and fruit characteristics consisting of number of male and female flowers, lengh and weight of plants, number and weight of fruits, dry matter percentage of fruits and plant and eventually YIELD of first and second grade fruits were recorded. Nitrate amout in fruits as measured for every harvest of morning and afternoon. Results showed that the number of female flowers increased with increasing the level of NITROGEN. This increment was correlated positively with the increment of plant length. NITROGEN application at levels of 150-250 kg/h showed significantly higher total YIELD compared to that lower levels. Nitrate amount in fruit tissue was increased with increasing level of applied NITROGEN and reached its highest level with application of 250 kg/h NITROGEN. The level of nitrate was always higher in fruits harvested in the morning compared to those harvested in the afternoon. The level of nitrate reached its toxicity threshold in treatments of 200 and 250 kg/h NITROGEN when harvested in the moning but for afternoon harvest it reached toxicity threshold when 250 kg/h NITROGEN was applied. It can be concluded that NITROGEN can be applied at 200 kg/h if it is supposed to be harvested in the afternoon but only 150 kg/h NITROGEN can be recommended if it is supposed to harvest in the morning.
