Abstract
The effect of application of different phosphorus rates on some parameters of nitrogen metabolism and yield in cucumber plants (Cucumis sativus L cv Brunex) was studied. All plants were grown under controlled conditions in an experimental greenhouse. The treatments consisted of applications of P at three rates in the form of H3PO4 (P1, 4 g m−2; P2, 8 g m−2; P3, 16 g m−2). The results showed a positive effect of higher P fertilisation (8 and 16 g m−2) on uptake, translocation and assimilation of in the leaves compared with the lowest P dose (4 g m−2), indicating that P is involved in the processes related to N metabolism in the leaves. In addition, the higher P rates strengthened the translocation of organic nitrogenous compounds (amino acids) towards the fruit, thereby perhaps also enhancing the maximal commercial yield. In conclusion, for improved cucumber cultivation under greenhouse conditions, 8 g m−2 gave maximal yield, while 16 g m−2 increased the metabolism and efficient utilisation of N. © 2000 Society of Chemical Industry
