PHYSIOLOGICAL AND BIOCHEMICAL EFFECTS OF MEPIQUAT CHLORIDE ON GROUNDNUT (Arachis hypogaea)

Abstract

                                Experiments were carried out to understand the physiological effects of Mepiquat Chloride (MC), 1, 1-dimethyl piperidinium chloride on groundnut (Arachis hypogaea L.) at different concentrations and in comparison with CCC (2-chloro ethyl trimethyl ammonium chloride). Foliar application of MC at 125 ppm on 35 DAS showed substantial increase in the nitrogen (N) content accounting for 23 per cent over the unsprayed control and 12 per cent over the CCC treatment. Phosphorus (P) and Calcium (Ca) contents were also increased, while potassium (K) was unaffected by application of MC.

Key words : Mepiquat chloride, groundnut, physiology and biochemistry
