Response of gazon grass plants to compost, humic acid and bio-fertilizer

Abstract

The present study was carried out at New Minia city, Minia, Egypt during the two seasons 2017/2018 and 2018/2019 to evaluate the response of growth characters of gazon grass plant to organic fertilization by compost and humic acid (at 100 ml/m 2 ) as well as bio-fertilizer (Minia azoten). All vegetative growth parameters; covering density, plant height, fresh and dry weights of clipping gazon grass showed high significant response for compost, biofertilizer and/or humic acid treatments of the three clippings. The applied treatment of soaked compost (4-liter) and humic acid combined with biofertilizer recorded the highest values of all vegetative growth parameters compared to control of the three clippings in both seasons. The combination of the high level of soaked compost + humic acid + biofertilizer recorded the highest values of growth parameters in all clippings of the two seasons compared to each of them alone and the control.
