摘要：Investigations were undertaken in ginger ( Zingiber officinale Rosc.) to assess the influence of growth regulators and chemicals on yield and quality under Lower Pulney Hills condition at Horticultural Research Station, Tamil Nadu Agricultural University, Thadiyankudisai, India. The variety Rio-de-Janeiro was utilized for the experiment. Eight treatments viz., brassinolide 0.1 ppm, paclobutrazol (pp333) 250 ppm, CCC 500 ppm, potassium chloride one per cent, salicylic acid 100 ppm, panchagavya three per cent, water were applied as foliar spray at third and fifth month after planting and control (untreated). Observations were recorded on growth, yield and quality. Plant height was higher in panchagavya treated plants whereas other growth parameters like number of tillers per plant and number of leaves per plant were higher in CCC treated plants. Yield characters viz., number of primary and secondary rhizomes per plant, length and girth of primary and secondary rhizomes, fresh and dry weight of rhizomes, yield per plot and yield per hectare were recorded highest in CCC 500 ppm foliar sprayed plants. For obtaining highest yield with good quality of ginger rhizomes, foliar application of CCC at 500 ppm could be recommended to the growers.
