An evaluation was conducted to develop a stochastic time series model, capable of prediction of rainfall and runoff in Karso watershed. The Karso Watershed selected for hydrological studies is one of the sub watershed of the Damoder dam catchment of upper Damodar Valley, comprising a cover the area[r]

A two year field study was conducted at RRS, Paiyur to study the influence of co inoculation of biofertilizers viz., Rhizobium, Phosphobacteria and VAM on soil microflora, plant biometric observation and yield parameters at periodical interval.

In general, wetlands are lands where water saturation is the dominant factor determining the nature of soil development and the types os plant and animal communities living in the soil and on its surface. The single feature that most wetlands share is soil or substrate that is at least periodically[r]

This experiment was carried out to investigate the stabilizing influence organic amendments on soil reaction and micronutrient availability. Three different soil types (viz. acid, neutral and sodic soil) were considered for our experiment to represent soils of the whole country. Soils were incubated[r]

We revisited a classic study of morphological variation in the oldfield mouse (Peromyscus polionotus) to estimate the strength of
selection acting on pigmentation patterns and to identify the underlying genes. We measured 215 specimens collected by Francis

Soil properties are sensitive to changes in the soil environment as influenced by vegetation, climate and inputs and losses of biomass and nutrients. Thus, the cropping systems with different management practices are likely to influence soil properties. Grid based soil survey was conducted in Mudhol[r]
