Energy partitioning and conserving efficiency in groundnut (Arachis hypogaea L.)

The energy compartmentation in different parts of groundnut was found in ascending order as shell, kernel, stem and leaves during kharif (June-Oct.) season whereas during rabi- summer (Jan.-May) season the same order of partitioning was found as shell, stem, kernel and leaves. The energy conserving efficiency at SI, PI and FAR was found to be 0.54–100%, 1.09–2.00% and 1.43–2.40% respectively. The energy harvesting capacity of groundnut did not differ during kharif and rabi-summer seasons though the total dry matter production and leaf area index were significantly higher and solar-irradiation values were signiicanly lower during the former season.
