This investigation was carried out under the field conditions for two successive seasons (2015/2016 and 2016/2017). In this concern, microrrhizal inoculations were set up in the main plots whereas the foliar application of nano-urea was arranged in the sub-plots, comprising 5 treatments, i.e. spray with water, spray with ordinary urea at a rate of 1500 mg N L-1, spray with nano-urea at rates of 500 mg N L-1, 1000 mg N L-1, and 1500 mg N L-1 (designated U0, U1, U2, U3, and U4 respectively). Generally, spraying kohlrabi plants with different urea forms increased significantly the studied vegetative growth parameters as well as the yield quantity and quality traits in the following order U4>U1=U3>U2>U0. Likewise inoculating plants with AMF improved significantly the investigated growth parameters and yield components. It seems that inoculating plants with AMF did not affect significantly the above-mentioned growth parameters and yield components when plants sprayed with nano-chitosan-urea at a rate of 1500 mg N L-1. Thus, spraying plants with 1000 mg N L-1 as nano chitosan-urea together with plant inoculation with AMF (U3M1) is the recommended solution to cut off the inputs of chemical N fertilizers by 33.3% as this integrated treatments recorded comparable results with the ones attained for the application of the full dose of urea.  }, keywords = {Kohlrabi,Arbuscular mycorrhizal fungi,foliar spray,nitrogen,nano-fertilizer}, url = {https://jpp.journals.ekb.eg/article_59469.html}, eprint = {https://jpp.journals.ekb.eg/article_59469_ceefd9e297a0f354800930ae97a9641d.pdf} } @article { author = {Shams, A. and Farag, A.}, title = {Implications of Water Stress and Organic Fertilization on Growth, Yield and Water Productivity of Cauliflower (Brassica oleracea Var.

So, the aim of this study is to decrease the level of irrigation water: 85 and 70% of full irrigation requirements (FI), versus 100% FI in presence of four compost rates (0, 4.8, 9.6 and 14.4 m3 ha-1). Results show that, deficit irrigation levels caused considerable reductions in many growth parameters and the total yield. But we can save 15% of the water used with an average total yield of 39.15 Mgha-1 and a yield shortage of 14.1% in both seasons. This is an acceptable level of decrease in view of the 36.3 Mgha-1 national average according to the 2017 Egypt’s Agricultural Statistics. The application of compost at different rates increases the growth, quality and quantity ​​of cauliflower at different water deficiency levels. The highest application rate of compost + 100% of FI recorded the highest values ​​in the characteristics of vegetative growth, total yield and NPK content in curd. The treatment 85% of FI + 14.4 m3 compost / ha came in the second rank recording significant differences with all other treatments in both seasons. The results also indicate that the water productivity in the case of 85% FI is significantly equal to the water productivity in case of 100% of FI in both seasons.
