| Abstract | ||
| Traits were carried out during the two growing seasons of 2007 and 2008 at 13-8osaily farm, Agricultural Research Center, El-Beira Governorate, Egypt. This research was conducted In an unheated greenhouse to determine the effect of different mulch colors and phosphorus fertigaticn on growth and yield of cucumber plant. Cucumber seedings (Cricurnissaffrust cv. firenjee 82) were grown In sandy soil. The plastic house constructor was covered with 200 urn local-UV•treated polyethylene sheet (PE) of 5.25 min width. Five mulch colors were used, I. e., red, green, blue, black and transparent. Control treatment was unmukhed. Three phosphorus fatigatlon levels 20, 40 and 60 ppm were added to soil under (afferent colors mulch and control. Soil temperature at surface and at 15 an depth of each mulch colors were measured. The vegetative growth, L e., plant height, number of leaves, fresh and dry weight of plant, early and total yield were recorded. The results showed that transparent muldi gave the highest sod temperature followed by black mulch In comparison with other mulch colors. The best vegetative growth (plant height, number of leaves, total leaf area, canopy fresh and dry weight) and yield (early and total) were obtained by transparent followed by black mulch. The transparent mulch color illataSed N, P and K % leaves content followed by black color with significant difference between them. The phosphorus use efficiency (PUE) was greatest at the lowest dose 20 ppm d P and deaeased as the P levels were Increased. On the other hand, the vegetate growth and yield were in vice case with PIJE. The interaction between mulch color and P gave the highest vegetative growth and yield under transparent mulch combined with 6Oppm P. | ||
