The study was conducted to find out impact of anthropogenic pressure on the biomass and productivity of forest floor vegetation in a submontane forest of Tarai of Kumaun Himalaya adjacent to Kashipur. The vegetation was studied at monthly intervals from April 2007 to April 2008 at two selected sites, site I and site II. Aboveground green biomass, aboveground dead biomass, belowground biomass and litter biomass were higher at site II (Gulzarpur forest). Similarly aboveground primary production, belowground production and total net primary production were recorded higher at site II, but litter production was higher at site I (Jogipura forest). Aboveground and belowground turn over was maximum recorded at site II but litter turn over was maximum recorded at site I. Based on the study, it is concluded that the forest at site I which suffer from anthropogenic pressure have low biomass and net primary productivity.Keywords

The soil samples of two forest types i.e., mixed deciduous type and plantation type were analysed for their physical and chemical properties at Tarai and Bhawar regions of Tarai West Forest Division, Ramnagar, Uttarakhand. Soil colour varied from grayish brown to light brownish gray and soil texture varied from silty clay loam to sandy loam. The result of the present study shows that the higher per cent of water holding capacity, pH, organic carbon, organic matter, total nitrogen, available potassium and available phosphorus was higher in mixed deciduous type forest than in plantation type forest. The pH indicate that the soil of both forest types were acidic in nature.Keywords

An experiment was undertaken to assess the genetic divergence, correlation co-efficient and path analysis among various horticultural traits in thirty-two genotypes of garden pea based on seventeen traits. The present investigation was revealed that all the pea germplasms significantly different for the traits phenotypic and genotypic correlation co-efficients among different characters showed that pod yield per plant had a positive and significant association with the number of branch per plant, number of pod per plant, number of cluster per plant. The path co-efficient analysis revealed that out of all traits studied, pod yield per plant had the maximum positive direct effect on the number of pods per plant followed by internode length, number of seeds per pod and number of branch per plant. All the genotypes were grouped into 5 clusters. The maximum number of genotypes was arranged in cluster-IV (10) and the other four clusters contained 22 genotypes each. Whereas highest inter-cluster distance was recorded between cluster V and II and lowest was observed between cluster IV and III. This result showed that it has the good thought of crossing between two different clusters which having high inter-cluster distance.Keywords
