Abstract

Rural India relies mainly on groundwater for drinking and agriculture. Unsustainable withdrawal of groundwater has led to the spectra of depleting the problem of water scarcity. The available groundwater quality is not only contaminated by hazardous pathogenic germs and anthropogenic substances but also geogenic substances is adversely affect the water supply of many regions. The groundwater of Challakere taluk had many threats such as anthropogenic activities, quality deterioration by agricultural activities and over exploitation and also persistence of continuous drought condition. The results of all the findings are discussed in details which reflect the present status of the groundwater quality of the study area. Groundwater is extremely important to the future economy and growth of rural India. If the resource is to remain available as high quality water for future generation it is important to protect from possible contamination. Hence it is recommended that suitable water quality management is essential to avoid any further contamination.Keywords: Groundwater quality analysis, Challakere, Subsurface Water Quality, Karnataka

Abstract

This paper documented the knowledge about the wild edible fungal flora of Ranupani Village of East Java Indonesia that used by indigenous Tenggerese tribes. Study was conducted by using semi-structured interview and purposive sampling. Data were analyzed quantitatively descriptive. Index of Cultural Significance (ICS) was used to evaluate the importance of non-wood forest yields for local people. Identification of edible mushrooms was based on Guidelines of Flora Diversity Data Collection. This study was focus on the three edible mushrooms which are eaten mostly by the villagers, i.e. Pleurotus sp., Clytocybe nebularis and Auricularia auricula. The result is the Ranupani residents perception of edible mushrooms and its potential as an alternative source of food based on local knowledge and local wisdom of Tenggerese. Pleurotus sp. has the highest preference and intensity to be consumed with 3,2 ICS. It means culturally, this edible mushroom were not too important but intensively used as a secondary food sources such as soup (added or sauted), chips (dried) and fried. Ranupani Villagers always consumed edible mushrooms in rainy season. The ability of residents to distinguish edible mushrooms are equal to the searching ability to find edible mushroom substrate. The residents will recognized the substrate of edible mushrooms on dead trunks of Pasang Tree (Lithocarpus sundaicus), Danglu (Engelhardia spicata), Kemlandingan (Albizia Montana), Casuarina (Casuarina junghuhniana) and acacia (Acacia decurens). Residents who do not have the ability to distinguish and searching were consumer, get the edible mushrooms by buying from the searcher or distributor in packs. The characteristics of an edible mushrooms are a discrete soft flesh of the fruit body, dark color, no ring on the stipe, the presence of insects (e.g. moths) in the lamellae) and the type of mushroom substrate. There were also assisted growths of wild mushrooms by the residents’ raw chop the dead tree trunk as a substrate deliberately. Respondents who knew the time of harvesting edible mushroom were 58.3%. Pasang mushrooms (natural & assisted growth) can be found throughout the rainy season, with an interval of 12 days for subsequent retrieval. While Barat and Kuping mushrooms are found throughout the rainy season, but randomly distributed in the forest. There were unwritten but spoken hereditary local wisdom for the sustainable of the edible mushrooms in Tengger. Only Tenggerese allowed collecting and selling the edible mushrooms in Tengger area to the Tenggerese themselves and tourist (local or foreign). This wisdom is supported by TNBTS regulation that the edible mushroom were not allowed exported out of TNBTS area. This wisdom expectedly makes sure that the edible mushrooms should be sustained in the forest. Keywords:Ethno-edible mushrooms, Ranupani

Abstract

Pseudomonas fluorescensandP. putida are Plant Growth Promoting Rhizobacteria (PGPR) that can produce growth hormone. The objective of this study is to know the effects of those two combined species of PGPR on seedling root growth of Jatrophacurcas. The condition of the seedling root determines the success of dry land cultivation. The root which has wider coverage, is larger in number, and is bigger in diameter makes seedling more resistant to stress in dry land environment. In the experiment, two kinds of plant materials are used for seedling, the Jatropha seed and stem material, which are treated in a mixed culture of PGPR. For the Jatropha seed, this mixed culture of PGPR is given at the same time of cultivating the sprout on the seedling medium. For the stem cutting, the PGPR is poured in together during the first watering of the seedling cultivation medium. In the fourthweek, the observed growth parameters are root length, root diameter, primary and secondary lateral root numbers, Root Length Density (RLD), Frequency of Lateral Root (FLR), and Specific Root Length (SRL). These data are analyzed using analysis of variant with DMRT test at 0.05 level of significance. The result of this study shows that PGPR tend to reduce FLR values on the seedling root made from seeds. On the seedling root made from stem cutting, PGPR increase the root length, primary and secondary lateral root numbers, root diameter, FLR and SRL values as well.

Abstract

The most serious threat to traditional rural ponds in Haryana is associated with transformed societal behavioural patterns, ethics, values and life style, amongst several others. The siltation of ponds with adjoining areas, soil coming in with rain water is a very serious cause of stratification of rural ponds. Also contracting of village community land for sun drying of cow dung cakes inspires villagers to overload periphery of each pond with cow dung turning the premises into grave-yard of dung. This dung is the major source of polluting pond water into blackish water with high load of organic matter. Moreover, it leads to over excessive eutrophication. Building of major highways and connectivity roads have resulted into compartmentalization and degradation of village ponds. Inhabitation of peripheral village ponds boundaries by lower section of society for dwelling purposes is more threat to wetlands. The indifferent inclination of villagers towards silted ponds drenched in bad odour and blackish sludge is the story of 80% of the cases. The total blockage of run-off rainy water towards the natural age old rural ponds due to obstruction by way of human inhabitation has resulted into desertification of shallow water sheet in 90% of the cases. The oblivion of harvesting dried silt in summer for brick making has spelled doom for the ponds turning them into flat ground through successive decades and so on. The water quality in all ponds was overshooting the decaying stage due to the continuous mixing of cow dung drenched rainy water. Over excessive usage of ponds for bathing of cattle, dumping of cow dung and rotten vegetables waste has turned ponds into live sinks of dirt, garbage and rural dairy wastes. Majority of village ponds are now out of existence or in deep black sludge laden or converted into Fish-Farming wetlands. The present studies have indicated that Winter migratory birds like Greylag Goose Anser anser, Bar-headed Goose Anser indicus, Mallard Anas platyrhynchos, Gadwall Anas strepera, Northern Shoveller Anas clypeata, Northern Pintail Anas acuta, Garganey Anas querquedula, Common Teal Anas crecca, Common Pochard Aythya ferina, Tufted Pochard Aythya fuligula, Common Coot Fulica atra, Little Ringed Plover Charadrius dubius, Kentish Plover Charadrius alexandrines, Spotted Redshank Tringa erythropus, Common Redshank Tringa tetanus, Marsh Sandpiper Tringa stagnatilis, Wood Sandpiper Tringa glareola and Pied Avocet Recurivirostra avosetta arrive in the extremely dilapidated rural ponds in Haryana from far off places including Russia, Siberia, China, and Caspian region, east Asia each winter season without any break. As such the extinction of ponds in Haryana directly threatens global avian biodiversity.
