Abstract: Allelopathy is the direct influence of a chemical released from one plant on the development and growth of another plant. Chemicals with allelopathic potential exist invariably in all plant tissues including leaves, flowers, stems, rhizomes and roots. Processes such as volatilization, root exudation, leaching and decomposition of plant residues release them into enviornment. Accumulation of more allelochemicals from weeds in fields causes soil sickness, reduced nitrification and nutrient uptake resulting in loss of crop yield. The present study has been conducted to examine the allelopathic effects of Grangia maderaspatena Frosk. on seed germination of three varieties of rice, i.e. Aiswarya, Kanchana and Harsha.

Keywords: River Wan, Water Quality Index, Pollution
Abstract: River Wan or Wanganga as it is often called, is an important tributary of River Godavari. It is principal source of water for drinking, irrigation and for industries in the vicinity in the Beed District of Maharashtra State. Anthropogenic activities are posing serious threat towards pollution of the riverian system. As a result , River Wan is not only serving as water resource, but acts as a sewer for municipal sewage, industrial effluents, and agricultural and urban run off. Because of multiple uses of the river water, river ecology has gained immense importance in recent years. It is, therefore, decided to study the physicochemical characteristics of the river at upstream at selected points. A simple comprehensive weighted arithmetic index method is used to assess overall quality of water for its intended use.

Abstract: The groundwater quality from Bhadravati tehsil has been assessed and results are presented in the paper. A total of 46 samples were collected out of which 23 samples represent shallow aquifers while remaining 23 samples correspond to deeper aquifers. The fluoride concentration varies from 1.0 to 4.4 mg/L in phreatic aquifers and from 0.5 to 2.9 mg/L in deeper aquifers. The present investigation indicates that the fluoride concentration is higher in shallow aquifers than in deeper aquifers. This may be ascribed to leaching of fluoride in to groundwater from weathered zone. The physicochemical conditions like decomposition, dissociation as well as subsequent dissolution are also responsible for feaching of fluoride, though with limited residence time. The inhabitants consuming the fluoride contaimanted water are suffering from different types of fluorosis.

Abstract: The natural recharging of groundwater in any watershed is a key parameter on which many other components of the watersheds are depended on. Finding out of natural recharging zones of groundwater and their preservation is a prime requirement for maintaining the socio-ecological equilibrium, but such attempts were not been dealt seriously till now owing to the intricacy involved in it. Here, a simple technique is developed to find out the natural recharging zones of groundwater in a watershed. The depth to water table (below ground level) measured in a systematic network of observation wells just before the starting of the monsoon rainfall and just after the initiation of the monsoon spell (after the heavy downpour of the initial 2-3 weeks) are used to delineate the natural recharging zones. The zones, which act as the areas of natural recharge of groundwater should be conserved and no landscape alternations should be allowed in such zones. The present simple methodology, which is cost effective can be applied to any river basins/watersheds to delineate the natural recharging zones of groundwater.

Abstract: Three minor epidemics of waterborne diseases were observed during the period of this study in Ekalavya Nagar, B M Sri Nagar and Manjunathapura in Mysore City. As it is necessary to increase both, knowledge and awareness among people, especially women, about freshwater pollution, the H2S strip test as well as waterborne diseases training programmes were arranged for women and students on the subject of the epidemic of waterborne diseases in their own areas. The programmes were about the faecal contamination of drinking water, simple purification methods in drinking water supply management and sanitation, and were made possible through this research work. The results showed that women who participated in the training programmes, especially from the areas affected by the epidemic of waterborne diseases, were interested in water related training such as the H2S strip test as well as the chlorination method. It also showed that the use of buckets and storage vessels is a major means of introducing contamination. Due to the daily water requirement, women had to store water and for this they use some vessels to collect drinking water. Usage of the freshwater and daily refilling of the vessels kept for drinking water can help the health of the house holders.
