Impact of Seed Hardening and Foliar Application of Growth Substances on Morphological Parameters of Groundnut (Arachis hypogaea L.)

An experiment was carried out during summer and kharif, 2022. A Factorial Randomized Block Design with three replications was used for an experiment that included seed hardening as one factor with nine levels while foliar spray of Chlorocholine Chloride @500 mg/L as another factor with two levels. Different morphological parameters were analyzed for the experiment at different time durations like 30, 50, 70, 90 DAS and at harvest. Days to initiation of flowering, days to 50% flowering, days to maturity were significantly minimum with GA3-150 mg/L seed hardening treatment. Meanwhile, plant height, number of primary branches per plant were also found significantly higher in seed hardening with GA3-150 mg/L while all these morphological parameters were found significantly lower after application of foliar spray of CCC @500 mg/L as compared to control. Thus seed hardening with GA3-150 mg/L and foliar application of CCC @500 mg/L is suitable for enhancing the yield of groundnut.
