Urea fertilization is a widely recommended practice in turfgrass management. However, the actual amount of nitrogen from urea that is available to turfgrass depends on many factors. A field study was conducted in South Gujarat to determine the effect of foliar (fast releasing) urea application versus neem oil coated (comparatively slow releasing) urea fertilization on specific vegetative characters like culm length, number of florets, leaf blade texture, fresh and dry clipping yield. The experiment was conducted on Hybrid Selection-1 var. of cynodon dactylon and laid out in Randomized Block Design with ten treatments replicated thrice. Treatments consisted of three annual nitrogen (N) inputs 100, 150 and 200 kg ha⁻¹, using three forms of urea, viz., 100% foliar, 50% foliar + 50% granular neem oil coated and 100% granular neem oil coated. Further, where no N fertilization was applied served as the control. The results suggested that N at the rate of 200 kg ha⁻¹ yr⁻¹ is needed to maintain acceptable turfgrass character. The turfgrass under 100% foliar application of 200 kg N performed well with respect to culm length, leaf blade texture, fresh and dry clipping yield. However, 100% neem oil coated urea was found effective for increasing number of florets.
