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

Sonbhadra is one of the important districts in Uttar Pradesh, where characteristic feature of growing trees in the farm land under traditional agroforestry system is continuing since generations. Present study was done to find out adoption status of predominant agroforestry practice in the district. Total 300 farmers were selected from six blocks of the district by a multistage sampling and semi-structured questionnaire survey was conducted among them. Madhuca latifolia, Butea monosperma and Tectona grandis trees were found highly adopted under agri-silviculture system on farmlands of the study area, wheareas, Emblica officinalis and Psidium guava were given first preference by the respondents for future adoption under agroforestry. Low water requiring crops were generally grown in combination with tree component under different agroforestry systems. Farmer prefer boundary planting and scattered planting pattern to grow tree species in their farmland under agroforestry system. Policy problem, shading effect, lack of market facility, long gestation period of tree and difficulty in cultural operation were expressed as main constraints in growing and further expansion of agroforestry trees on farm land in the district Sonbhadra.
