Impact of foliar application of plant growth regulators on seed filling and seed multiplication rate in groundnut (Arachis hypogaea L.)

Abstract: The investigation was directed to assess the impact of foliar spray with plant growth regulators on flowering characteristics of groundnut (Arachis hypogaea L.) var. TMV 7 and their corresponding influence on pod and seed attributes. The plants were sprayed with plant growth regulators such as Ethrel, Chlorocholine chloride (CCC), Maleic Hydrazide (MH), Naphthalic Acetic Acid (NAA) and Mepiquat chloride (PIX) in different concentrations at 60 days after sowing (DAS). The weight of pod and seed yield plant-1 obtained in the plants sprayed with plant growth regulators recorded statistically significant variation. In all the treatments, the number of flowers in the later stages were reduced which reduced the number of immature pods and increased the number of double seeded pods, eventually contributing to higher seed yield than the untreated (control) plants. Among the treatments, the highest pod yield per plant was recorded in NAA 200 ppm (29.33 g) followed by Ethrel 400 ppm (24.88 g) when compared with the control (15.79 g) in which the lowest yield was obtained. These treatments can be utilised for increasing the efficiency of pod filling thereby increasing the seed yield in groundnut.
