The present study is concerned with the analysis of landform characteristics of Salda River basin and its impact on agriculture land use pattern. The Salda basin is one of the sub-basins of Subarnarekha River, with diversified landscape pattern in the western part of Purulia district in West Bengal. This basin is constituted by plateaus, plains with terraces, scarps, inselbergs, which is evolved under polycyclic evolution. The development of polycyclic geomorphic processes in this basin is typified by diverse morphology and drainage, which largely influence the land use pattern in this area. These diverse landscape patterns indicate the interaction of litho-tectonic-structural and various geomorphic processes with recent human intervention. The main objectives of the present study are to analyse the landforms characteristics, correlate them with land use and identify problems as well as prospects of agricultural land utilization. The entire study is based on both primary and secondary data. Extensive field survey has been conducted to collect primary information regarding terrain characteristics, micro relief, slope characteristics, hydrological attributes, soil character, natural vegetation, environmental hazards. The Survey of India topographical sheets, meteorological data, agricultural production data, land use and land cover data have been collected for the analysis of geomorphological characteristics, land classification, and agricultural land use pattern. This study reflects the typical land characteristics of the fringe area of Chhotanagpur plateau, where some typical geomorphic attributes control the productivity of the land and also controls the socio-economic conditions of the local people. The present authors have tried to examine the typical geomorphic attributes and their effects on present productivity of the land in a micro level study, where agriculture is the main source of income.

ObjectiveThis study was designed to find out the fungal aetiological agents in chronic suppurative otitis media (CSOM) patients attending tertiary care centre of Nepal. ResultTotal 123 samples of 117 patients, outdoor as well as indoor from Department of ENT and Head and Neck Surgery (HNS) TUTH, Maharajgunj, Kathmandu those specimens were processed and among them, 23(18.7%) was found potassium hydroxide (KOH) mount positive whereas positive growth was in 27 specimens. The prevalence rate of fungus was 21.95 percent in which the main pathogen was Aspergillus species (51.8%), followed by Candida species (14.8 %). Keywords: CSOM, KOH, Fungal culture, Aspergillus
