| Abstract | ||||
| A field experiment was conducted during the two successive seasons 2007/2008/2009 and 2008/2009/2010 at the Agriculture Experimental Station of the College of Agriculture and Veterinary Medicine, Qassim University, Buraydah, Al-Qassim, Saudi Arabia. The experiment aimed to study the effects of mineral NPK fertilizer and incorporation of organic compost to the soil on growth and quality of NuMexSahara Bermudagrass (Cynodon dactylon (L.) Pers.) grown in a sandy soil throughout the year. Seeds were planted on September 15th of 2007and 2008 for the first and second seasons respectively. In treatments containing compost, compost was incorporated to the top 20 cm of the soil at two rates; 1 and 3 kg per square meter, before planting during soil preparation of the beds. Inorganic water soluble NPK fertilizer (14-38-10 +Mg +TE), was applied at three levels; low (100 g/m2/year ), medium (200 g/m2/year) ,and high (300 g/m2/year ). The mineral fertilizer was divided into four equal applications (after planting on February of the following year, May, September, and February of the next year). Data included turfgrass establishment (coverage) rate, clippings weight, turfgrass quality, root/shoot ratio, and chlorophyll content, carbohydrates, nitrogen, phosphorus, and potassium % in the clippings. Data showed that the earliest establishment of NuMexSahara Bermudagrass was achieved using high NPK (300 g/m2/year ) either alone or combined with 1 or 3 kg compost incorporated to the soil. These treatments also maintained turfgrass quality above the acceptable level throughout the entire season, including late fall and winter. The best results for growth, quality, and all previously mentioned measurements were obtained by applying 300 g/m2/year NPK fertilizer divided to 4 equal applications to Bermudagrass grown in the soil incorporated with 3 kg of the bioorganic compost during soil preparation. | ||||
