During 2015 and 2016 seasons, Zaghloul date palmsat Dahmro village, Maghagha district, Minia Governorate treated with silicon and/or some nutrients namely N, P, K, Mg, Zn, Fe, Mn, Cu and B. The merit was examining the effect of these nutrients on growth and palm nutritional status. Treating the palms three times with silicon and/or macro and micronutrients caused a remarkable stimulation on number of new leaves/palm, leaf length, pinnae area, number of pinnae/leaf, leaf area, number of spines per leaf and spine length and percentages of N, P, K and Mg in the leaves over the control treatment. Using macro and micronutrients was superior than the single application of silicon on enhancing all growth aspects and leaf chemical components. Combined application of silicon and nutrients surpassed the application of each alone in this respect. Conclusively, for enhancing growth and palm nutritional status of Zaghloul date palms, it is suggested to spray the palms with a mixture of silicon, N, P, K, Mg, Zn, Fe, Mn, Cu and B three times. |
