Abstract

The study conducted in the silvipastoral system indicated that the collar diameter, DBH and tree height for stands of Dalbergia sissoo, Gmelina arborea, Pongamia pinnata and Terminalia arjuna were ranged from 12.01 to 15.03 cm, 9.06 to 13.1 cm and 5.40 to 7.19 m respectively. The over all dry matter production was found in order of a D.sissoo (45.18 kg tree^-1) G. arborea (36.97 kg tree-1) P. pinnata (26.74 kg tree-1) and T. arjuna (23.12 kg tree -1). The under storey pasture crop of Chrysopogon fulvus > Stylosanthes hamata get established during initial growing stage of silvipasture system. As soon as the tree canopy developed the invasion of local/ native flora gets interacted with the growing species and started to influence the quality and quantity production of established pasture crops which ultimately increase the productivity of forage grasses. The study indicated that Dalbergia sissoo and Gmelina arborea species based silvipasture system was found comparatively more suitable for development and utilization of red lateritic wasteland. The systematic compatible tree-grass-legumes combination was observed better for optimum growth and biomass production as well as conservation of environment.

Abstract

Structure composition and diversity of woody vegetation of sal mixed dry tropical forest of hmalamdi watershed in barnawapara sancuary, Raipur district of Chhattisgarh, India was studied in over and uner storey forest in four different aspects, Nine prominent tree species were recorded in over and under storied forest with the predominance of Shorea robusta in all the aspects. In the overstorey(pooled), relative density values ranged from 3.03 to 43.94 and understorey from 0.04 to 42.71, Shorea robusta recorded highest relative density in over and understorey vegetation followed by Madhura indica and Tectona grandis The IVI values ranged from 15.88 to 78.62 in overstorey and 14.28 to 83.89 in understorey. The highest IVI values recorded by Shorea robusta in both over and understorey. The diversity(Shannon index value) ranged 1.28 (northern aspect) tp 1.67 (southern aspect) for overstorey and 1.10 (northern) to 1.59 (western) for understorey. The study illustrated that overstorey tree strata in the forest is more dominant than understorey. The Shamun index, Simpson's index. Spceies richness, Equitability and Beta diversity values were almost higher in overstorey as compared to unerstorey thereforer the present study reveals the normal regeneration pattern in the forest.

Abstract

The paper deals with the socioeconomic status and livelihood support through traditional agroforestry systems in Garhwal Himalaya, India. The predominant traditional agroforestry systems reported in the area were agrisilviculture (AS), agrihortisilviculture (AHS) and agrihorticulture (AH). A total 443 households were studied from the six selected villages with a family size of about 5.5 members per family. The adult literacy rate was 43% in marginal, 54% in small and 73% in medium-large land holding families while the child education rate was 86, 98 and 100%, respectively. The livestock were kept by 37 to 56% families in different villages. Each of these households has 2 to 4 milch animals and only 8 to 18% families kept oxen. The average daily fuel wood consumption during summer and winter in different villages varied from 84.41 to 538.45 kg/day/village and 156.75 to 701.01 kg/day/village which are supplemented by existing agroforestry upto considerable extent. The utilization of tree fodder varied from 305.02 to 1015.17 kg/day/village in the summer and 659.53 to 2015.52 kg/day/village in the winter season which is also supplemented by traditional agroforestry trees in a sizable limit. The land holding size ranged from 0.03 to 5.6 ha per family with 83.3% families were under marginal category, 14.7% under small category and 2.03% families comprised of medium-large landholding size. Agroforestry practice reported to be supportive and sustainable practice in this area with 20.24% monetary gain over sole cropping. The traditional agroforestry as such plays a significant role in the different facets of the household for their sustenance.
