Abstract: An experiment was carried out to assess the impact of foliar spray of plant growth regulators (PGRs) and nutrients on flowering and productivity of groundnut (Arachis hypogeal L.) var. TMV13. Different plant growth regulators and nutrients such as ethephon, mepiquat chloride, mono ammonium phosphate (MAP), and potassium chloride (KCl) were sprayed at different stages. Among the treatments, foliar spray of ethephon @ 50 ppm + mepiqout chloride 125ppm @ 25 DAE (days after emergence) + ethephon @ 50 ppm at 60 DAE found to be best treatment by means of yield. The study clearly showed that foliar spray of PGRs and nutrients can increase the productivity of groundnut.
