SUMMARY
A field experiment entitled “Effect of Bio-regulators application on productivity of barley (Hordeum vulgare L.) in arid conditions of Western Rajasthan” was conducted on loamy sand soil of the Agronomy farm, College of Agriculture, Bikaner during rabi season of 2009-2010. The experiment was comprised of three bio-regulators (500 ppm thiourea, 100 ppm thioglycolic acid and 100 ppm salicylic acid) spray at 40 and 60 DAS with water spray. Foliar spray of bio-regulators (TU, TGA and SA) significantly improved plant height, dry matter accumulation, effective tillers per meter row length, spike length grains per spike and test weight of barley over water spray control. The maximum grain yield (2743 kg/ha), straw yield (3101kg/ha), biological yield (5844 kg/ha), harvest index (47.10 %), protein and total protein content were obtained with 500 ppm thiourea at 40 and 60 DAS.
Key words: Bioregulators thiourea, thioglycolic acid, salicylic acid, productivity, Hordeum vulgare
