| Abstract | ||||
| During the two successive summer seasons of 2011 and 2012, two field experiments were carried out in a private farm at El-Mahalla El-Kubra - Gharbia governorate to investigate the effect of nitrogen fertilization forms i.e. ammonium sulphate and calcium nitrate and some bio-stimulants i.e. humic acid, fulvic acid, EM and yeast extract under high temperature on fruit quality of cucumber (Cucumis sativus L.) cv. Prince. The results showed that the effect of N-forms was significant on all cucumber fruits quality. The maximum values of these parameters were executed for the treatment of (50%NH4 + 50%NO3). Foliar spraying of cucumber plants with bio-stimulants significantly increased the mean values of fruits quality and decreased fruit contents of nitrate as compared with the control treatment. The best foliar application was (EM) effective microorganisms at 20 ml/l. Therefore, using nitrogen fertilization as (50% NH4 +50% NO3) combined with spraying (EM) at 20 ml/l could be recommended in case of high temperature conditions. | ||||
