Vegetation conditions in various plant communities and their performance in district Tharparkar, Sindh, Pakistan

Abstract

Six villages were registered for the experimental purpose/plantation where more than 25,000 plants were planted to develop range forest. These plants were developed at Marvi nursery PARC-Arid Zone Research Institute, Umerkot and some were purchased from private nursery situated at Mirpurkhas. Results revealed that maximum plants mortality rate was found at village Ratnore and lowest mortality of plants was observed at Mithrio Charan. Plants damaged due to unknown reason (natural), termite attack and diseases. In various locations most of plants were affected by termites than others biotic and abiotic factors. The most influenced plant was Prosopis cinerera. Maximum plants survived numbers of grafted ber was found at village Ratnore, the biomass production of green and dry grasses was taken after harvesting. A highest green grass weight 21812.58 kg and dry 3439.83 kg were observed from elephant grass stock and lowest green weight 5001.92 kg from Gatten grass and dry weight 477.57 kg per acre were recorded from Rhode grass 1 (Sabri). Gatten grass and Rhode grass 1 (Sabri) were found lower weight. All these seven grasses showed excellent performance except Elephant grass and Gatten grass. These two grasses needed more water as compared to remaining five species. These grasses when fed by goats their milk production was increased and goats like to feed these grasses. The pictures of these grasses showed their appearance and health irrigated by underground brackish water with more than 2200 ppm.
