Field experiments were conducted at Agricultural College and Research Institute, Madurai during late rabi season of 1997-98 and 1998-99 and the results revealed that foliar spraying of 2 ppm Triacontanol at 35 and 65 DAT significantly increased the LAI, LAD, chlorophyll content and these led to higher grain yield (6346, 6410 kg ha during 1997-98 and 1998-99 respectively). This was followed by application of 20 ppm Benzyladenine and Arappu leaf extract.
