Phenological events of rhododendron (Rhododendron arboreum Sm.) were monitored along elevation gradients in distinct ecological settings. The observations were carried out between 1500 and 2500 m elevation in Central Himalaya. The phenological events, i.e. bud formation, bud bursting, leafing, flowering, fruit formation and seed formation were recorded. Phenological duration and synchrony of all these phenophases were determined within site and along the elevation gradient in each study site. Our observations showed high synchrony throughout the elevation gradient, especially for peak flowering. Temperature, rainfall, age of the observed trees and site characteristics were related to initial and peak flowering dates. The circumference varied from 35.0 ± 2.73 to 140.0 ± 2.88 cm; similarly, height varied from 5.0 ± 1.02 to 16.5 v 1.41 m. All the phenological events began early at low elevation and were delayed at higher elevation. R. arboreum had a sharp flowering peak from January to March. Wet season flowering was rare, and seed formation occurred in summer. The climatic conditions affected the phenological characters of R. arboreum.Keywords

In this study, we assess quantitative soil loss in the Himalayan ecosystem of Uttarakhand, India using universal soil loss equation and geographic information system. The analysis shows that about 359,000 (6.71%), 473,000 (8.84%) and 1,750,000 ha (32.72%) area is under moderately severe (15–20 tonne ha–1 year–1), severe (20–40 tonne ha–1 year–1) and very severe (40–80 tonne ha–1 year–1) soil loss respectively. It clearly indicates that about 48.3% area of the state is above the tolerance limit of 11.2 tonne ha–1 year–1 of soil loss. This explains the need to undertake appropriate soil and water conservation measures to mitigate the topsoil loss in this fragile Himalayan ecosystem. Based on the degree of severity of soil loss, appropriate soil and water conservation measures need to be adopted on priority basis. The agriculture practices should be diversified with farm-forestry, agro-horticulture and/or agro-forestry to minimize soil loss in cultivated areas of the state. Such conservation programmes help mitigate accelerated soil erosion, restore the fragile ecosystems and generate employment opportunities for the needy.Keywords

Identification and delineation of potential areas for different crops, both at country and state level by using available legacy data assumes importance, in order to preserve and conserve these areas to feed the increasing population and future generations. In this direction, a new integrated approach has been developed to identify potential areas for different crops and the same has been validated. Identifying and delineating commodity specific areas/zones, would help in enhancing the productivity and profitability and framing of land use policies.Keywords
