Effect of growth regulators on growth, yield and quality of Sewan grass (Lasiurus sindicus Henr.)

A field experiment was conducted during Kharif, 2011, 2012 and 2013 for consecutive three years at Agricultural Research Station, S.K. Rajasthan Agricultural University, Bikaner to study the effect of growth regulators on growth, yield and quality of Sewan grass. The experiment was laid out in randomized block design and replicated thrice. Results showed that maximum plant height (80 cm), total tiller/m row length (174), spike length/plant (8.25 cm) and test weight (2.76 g) was recorded with salicylic acid (100 ppm) seed soaking + thiourea (0.05%) foliar spray. Highest seed (15.35 q/ha) and grass (40.89 q/ha) yield of Sewan grass was recorded with thiourea seed soaking + salicylic acid (100 ppm) foliar spray and maximum values of sustainability yield index was recorded with thiourea soaking + salicylic acid (100 ppm) spray for grass yield (37.25%) and with salicylic acid (100 ppm) soaking + no spray for seed yield (7.68%). Further, crude protein (10.11%), crude fibre (33.25%) and total ash (6.04%) content were recorded maximum with thiourea seed soaking + thiourea (0.05%) foliar spray.
