Abstract

Canola has been introduced in Egypt recently as a promising new vegetable oil crop especially in the newly reclaimed lands usually exposed to different environmental stresses which limits their growth and productivity. Field experiment had been done Research and Production Station, National Research Centre, Nubaria location, Beheira Governorate, Egypt during 2019/2020 to study the economic analysis of compost (0, 2, 4, and 6 ton fed) and zinc (0, 50, and 100 ppm) application on Canola production under deficit irrigation condition. Results on the effect of compost and zinc application rate and their interactions under sufficient and deficit irrigation treatment observed that application of 6.0-ton compost fed combined with 100 ppm Zn increased the values of seed, straw, and oil yield of canola under sufficient and deficit irrigation treatments over the remaining treatment applied and control. Increased zinc application rate from 50 ppm to 100 ppm led to an increase in the seed yield, straw yield, and oil yield of canola. The Canola plant receiving 6-ton compost in combination with 100 ppm foliar application of Zinc registered the highest gross returns, net returns, Benefit: cost ratio of seed yield, straw yield, and oil yield an oil cake yield followed by 50 ppm Zn foliar application with the same compost level as compared to other treatments and control under sufficient and deficit irrigation treatment, respectively. This practice can help to obtain higher profit over the conventional application of a recommended dose of fertilizers to the canola crop.
水分胁迫条件下堆肥和施锌对油菜生产影响的经济评价
埃及最近引进了油菜籽作为一种有前途的新型植物油作物,特别是在新开垦的土地上,通常暴露于不同的环境压力,限制了它们的生长和生产力。2019/2020年,在埃及Beheira省Nubaria地区的国家研究中心研究和生产站进行了田间试验,研究了亏缺灌溉条件下施用堆肥(0、2、4和6吨饲料)和锌(0、50和100 ppm)对油菜籽生产的经济分析。结果:在充分和亏缺灌溉条件下,堆肥用量与锌用量及其相互作用的影响观察发现,在充分和亏缺灌溉条件下,6.0吨堆肥配100 ppm Zn均显著提高了油菜种子、秸秆和油料产量,高于其余处理和对照。锌用量由50 ppm增加到100 ppm,籽粒产量、秸秆产量和油菜籽产量均有提高。在充分灌溉和亏缺灌溉处理下,与其他处理和对照相比,施用6吨堆肥并叶面施用100 ppm锌的油菜籽植株的总收益、净收益、种子产量、秸秆产量和油饼产量的效益:成本比、净收益、净收益、净收益和净收益最高。这种做法可以帮助获得比常规使用推荐剂量的化肥对油菜籽作物更高的利润。
