Standing Biomass of Various Plant Parts in Selected Tree Species of Dry Deciduous Teak Forest in M.P.

Abstract

The present investigation was carried out in teak forests of Gourjhamer Range of Sagar Division The teak forests of this Range constitute about 16.4 per cent of the total teak forests and 8.7 per cent of the total mixed forests of Sagar District. In the present investigation. the organic matter productivity of four important tree species viz T. grandis. T. tomentosa A. latifolia and D. melanoxvlon were studied in relation to their grith at breast height (gbh), and age (in T. grandis) only. While comparing different species for their net primary productivity it was found that A. latifolia was more efficient in dry matter production followed by T. tomentosa, T. grandis ond D melanoxylon. At 50-55 cm ghh the total production per tree was 433.50 kg in A. latifolia, 184.18 kg in T. tomentosa, 157.89 kg in T. grandis an 78.65 kg dry matter in D. melanoxylon. Mean annual productivity can be expressed accurately in T. grandis due to the presence of prominent annual growth rings whereas in T. tomentosa, A. latifolia, D. melanoxylon and other species of dry deciduous forest, due to the absence of prominent growth rings, assessment of age is not accurate. In such cases, gbh rather than age was found to be useful in comparing the productivity of different species.
