Effects of spacing and foliar application of urea on proliferation of Bermuda grass (Cynodon dactylon L. Pers. × Cynodon transvaalensis)
Abstract
An experiment was conducted to study the effect of different spacing and foliar application of urea on proliferation of bermuda grass (Cynodon dactylon L. Pers. × Cynodon transvaalensis) in floriculture unit of the Department of Horticulture, Faculty of Agriculture, Annamalai University, Tamil Nadu during the year 2013–2015. Bermuda grass sprigs were planted in different spacing levels (10 × 10 cm, 15 × 15 cm, 20 × 20 cm and 25 × 25 cm) and foliar spray of urea (@ 1%, 1.5% and 2% as a source of nitrogen) was applied 7 and 15 days after planting with twelve treatment combinations in factorial randomized block design with three replications. Observations were recorded on percent ground cover, number of runner, length of runner and shoot density, root length, shoot length, root/shoot ratio, leaf area and number of leaves per clipped shoot at 60 days after planting. From the results, it was found that the earliest spread and ground cover were observed in the treatment S4 (10 × 10 cm spacing) in combination with foliar application of Urea (N3:Urea 2%) applied twice at seven and fifteen days after planting.
