Plants of spreading type of groundnut (Arachis hypogaea cv. M-13) were given foliar sprays separately with phenolic compound β-naphthol-1-amino, 4-sulphonate (50, 100, 150 μg/ml) and a mixture of aliphatic alcohols—C-24 to C-34 (1 μg/ml) at 30 and 37 days after flowering. In the treated plants, the total number of flowers produced per plant, number of flowers in the initial 3 weeks increased significantly. Both the compounds required lesser number of days for the production of initial 70 flowers as compared with control. With aliphatic alcohols several of the kernel and pod characters increased significantly over the control. Flowering in phase A showed a positive significant correlation with some of the yield characters though it was significantly negatively correlated with harvest index. The compounds were effective in inducing the establishment of early potential sinks and caused efficient mobilization of assimilates for a longer filling period in the pods.
