In recent years. high priority has been given to the installation of tile drains in old cultivated lands to stop the decline in yields attributable to water logging and increased salinity. Economic feasibility parameters have been used to evaluate the economic feasibility of project. Cropping budgets of wheat, rice, maize, cotton and sugar beet as main crops in Kafr EI-Sheikh Governorate has been used to calculate net returns per feddan. Results of study showed the positive impact of tile drainage on productivity. Economic returns for feddan have increased after establishment of tile drains. Internal rate of return of the project estimated to be 24.35%. Rate of capital turnover has been calculated by 4 years. Benefit-cost ratio estimated to be 1.18. This means that tile drainage systems is economically feasible. Also tile drainage systems have more economical effect comparing with surface drainage, as tile drains allows to save more agricultural land, simplify the use of machinery, improve irrigation and drainage rates, reduce maintenance costs per feddan, remove excessive soil salinity and having better sanitary conditions. The study gave some recommendations which could increase the benefits of tile drainage systems and raise the agricultural production.

This study was conducted at the Agricultural Research Station, Hada El-Sham, King Abdulaziz University during 2006 and 2007 seasons. Four canola varieties, Callypso, Pactole, Sero-4 and Sero-6 varieties were tested under four nitrogen fertilizer rates (0.00, 92,138 and 184 kg N/ha) to determine the effect of nitrogen fertilizer on the canola (Brassica napus L.) seed yield, yield components and seed quality. The results showed that as nitrogen fertilizer rate increased, plant height, number of fruit / plant, 1000-seed weights, seed weight / plant and protein content increased. However oil content (%), was the highest under 92 kg nitrogen rate, then significantly decreased under the higher nitrogen rates. In terms of variety differences, the plant height data revealed that Sero-4 was the taller, followed by Sero-6, and then Callypso and Pactole varieties and Pactale and Sero-6 varieties produced the highest number of fruits / plant and significantly dominated over the Sero-4 and Callypso variety. In addition, Pactale and Sero-4 had the highest 1000-seed weights without significant differences between them, while Callypso variety was the lowest. Pactole variety was also the highest in seed weight / plant, while Sero-4 and Sero-6 varieties were not significantly different in seed weight / plant. Pactole variety was the highest in protein content followed with a significant difference by Sero-4, then Sero-6, while the lowest variety in protein content was Callypso variety. The rate of 138 kg N / ha produced the highest seed yield / ha (1550.51 kg), protein content (28%) and had 34.10% oil content. Oil content of the studied varieties ranged from 37.80% for Callypso variety to 32.04% for Sero-4 variety, and the statistical comparisons showed significant differences among the four studied varieties. Furthermore, iodine value and refractive index of the oil under the effects of nitrogen fertilizer rates were not significantly different from
本研究于2006年和2007年在阿卜杜勒阿齐兹国王大学Hada El-Sham农业研究站进行。以油菜品种Callypso、Pactole、Sero-4和Sero-6为试验材料，在4种氮肥用量(0.00、92,138和184 kg N/ha)下，研究了氮肥对油菜种子产量、产量构成和品质的影响。结果表明:随着施氮量的增加，植株高度、单株果数、千粒重、单株粒重和蛋白质含量均增加;而含油量(%)在施氮量为92 kg时最高，在较高施氮量下显著降低。在株高差异方面，Sero-4最高，Sero-6次之，Callypso和Pactole以及Pactale和Sero-6的单株果数最高，显著优于Sero-4和Callypso。其中，Pactale和Sero-4品种千粒重最高，差异不显著，Callypso品种最低。Pactole品种单株种子重最高，Sero-4和Sero-6品种单株种子重差异不显著。蛋白质含量最高的品种是Pactole，其次是Sero-4，其次是Sero-6，蛋白质含量最低的品种是Callypso。施氮138 kg / hm2，籽粒产量最高(1550.51 kg)，蛋白质含量最高(28%)，含油量最高(34.10%)。所研究品种的含油量从Callypso品种的37.80%到Sero-4品种的32.04%不等，4个品种间差异显著。氮肥施量对油的碘值和折射率影响不显著
