USING OF BIOLOGICAL AND NANO-MICRONUTRIENTS FERTILIZERS FOR ENHANCING GROWTH, COVERING DENSITY AND GREENING OF SEASHORE PASPALUM (Paspalumvaginatum, SWARTZ) GRASS

Abstract

In order to enhance seashore paspalum grass growth and quality, bed (28 × 40 cm) experiment was done at Horticulture Department roofof Zagazig University, Egypt during 2021/2022 and 2022/2023 seasons. The main factors of this experiment were, firstly bio-fertilizers type (control, nitrobein, phosphorein and nitrobein + phosphorein), secondly nano-micronutrients named MagroNanoMix (0.0, 0.25, 0.50 and 1.00g/l) beside their interaction treatments. The experimental design was split-plot design which had 16 treatments in three replicates. The results pointed out that fertilization seashore paspalum with 0.5g/m2 of nitrobein + 0.5 g/m2of phosphorein significantly enhanced plant height, herb fresh and dry weight per area, roots fresh and dry weights per area, covering density (%) and total chlorophyll content (mg/100 g as fresh weight) compared to the other bio- fertilizertypes. Nano-micronutrients fertilizer at any tested concentration significantly increased growth traits and leaf greening compared to control. The highest values of all above mentioned traits were obtained by fertilization with 1000 ppm of nano-micronutrients. Generally, to enhance growth of seashore paspalum grasses and increase covering density and their greening it is recommended to fertilize plants with nitrobein + phosphorein each at 0.5 g/ m2and spraying them with nano-micronutrients at 1000 ppm three times during winter season.
