Ecological Study Of Sesamum Indicum L. With Reference To Biomass And Primary Productivity In Gaya District, Bihar

Abstract

An Ecological Investigation On Sesamum Indicum L. Was Undertaken To Evaluate Biomass Production And Productivity Pattern Under Gaya Agro-climate, Bihar. Field Work Was Executed In Kharif Season 2023-24 At Three Locations - Sherghati Upland, Barachatti Midland And Bodh Gaya Lowland.Three Cultivars Krishna, T-78 And RT-351 Were Evaluated At 15 Days Interval From Germination To Maturity. Germination Potential Was Maximum In RT-351 (88.4%) Followed By Krishna (82.1%). Standing Dry Matter Showed Progressive Increase Till Harvest And Maximum Value 284.6 G/m2 Was Recorded In RT-351 At Site-III. Above Ground Parts Shared 82% Of Total Dry Matter And Below Ground 18%. Highest Net Primary Production 4.12 G/m2/day Was Noted During 45-60 Days After Sowing At Flowering Stage, Lowest 0.85 G/m2/day At Maturity. Seed Exhibited Highest Energy Value 6542 Kcal/g Compared To Leaf 4320 Kcal/g, Stem 4210 Kcal/g And Root 3980 Kcal/g. Accumulation Of NPK Was In Order Seed > Leaf > Stem > Root With Maximum N 3.42%, P 0.82%, K 0.91% In Seed. Present Study Revealed Suitability Of Gaya Climate For Sesame And Superiority Of RT-351 For Higher Biomass And Oil Yield In Magadh Region.
