A total of 366 faecal samples including 225 cattle and 141 buffalo of different age groups were randomly collected and analyzed for presence of gastrointestinal helminthes parasites from five different blocks on both sides of Burhi Gandak River in Samastipur district of Bihar in 2015-16. Among cattle 115 (51.11 %) and among buffalo 88 (62.40%) samples were found positive for different species of gastrointestinal helminthes. The prevalence of trematodes, nematodes and cestodes in cattle were 44, 6 and 8 percent, respectively and in buffalo were 35, 18 and 15 percent, respectively. Mixed infection in cattle and buffalo faecal samples was 6.8% and 5.6%, respectively. 4.40 % cattle and 6.60 % buffalo were severely affected, in which egg count per gram was more than 1600. In 1-90 days age group calves 65.6 % cattle and 90.47 % buffalo were positive.

The results were indicated that analysis of variance for twenty three parents and their sixty F1s were computed for all the twelve characters and mean sum of squares. Highly significant differences were observed among the treatments for all the twelve characters under the study. This indicated the presence of an appreciable amount of variability in the base material as well as in the material generated. The mean values of all the twelve characters in parents and F1 progenies and variability are varied from character to character. The appreciable variance among the parents and F1s was found for all the twelve characters. However, the magnitude varied from character to character.

It is a known fact that as the economy grows the demand for services increases. “The service sector is currently the fastest growing sector of the Indian economy”. Total contribution by travel and tourism sector to India’s GDP is expected to increase from Rs 15.24 trillion (US$ 234.03 billion) in 2017 to Rs 32.05 trillion (US$ 492.21 billion) in 2028. Hospitality and tourism is an important contributor to India’s service portfolio. The hospitality industry in India is changing at a very fast pace. Innovation is the buzzword in the industry. The Indian hospitality industry is witnessing a major shift wherein apart from traditional business or leisure travel, India’s hospitality sector has been witnessing interest from various segments like meetings, incentives, conferences and exhibitions (MICE), eco tourism, wellness tourism, spiritual and pilgrimage tourism. The Indian government has taken up various reforms to bring the pace in the industry growth with liberalization in the regulatory framework, investment friendly schemes, extensive support for creating a world class infrastructure, initiating better air and land connectivity, incentivizing regional set-up in tier III and IV cities, exploring the untapped geographical resources which has led to a comprehensive growth of the Indian hospitality industry. This paper focuses on impact of the hospitality industry in the development and growth of Indian economy which have transformed the scenario of the industry altogether. It also attempts to study the trends on the hospitality industry and the Indian economy at large.

Availability of quality freshwater is one of the most critical environmental issues of the twenty first century (UNEP, 2002). Urbanization leads to the environmental pollution, i.e., urban growth leads to the increasing of slums, solid waste disposal, provision of transport facilities, conjection and groundwater contamination. Groundwater is an important water resource for domestic and agriculture in both rural and urban parts of India. Pollution of groundwater comes from many sources. Groundwater contamination in a major issue, especially in industrial areas especially like Dindigul. The presence of large number of tanniers and allied industrial unit such as dyeing and bleaching units in and around the town are the main factors, which affect the environmental quality of the town. Dindigul town is not having the physical expansion since 1981 with an area of 14.01sq.km. Only wards are increased by enjoying the rapid growth of population. Dindigul is the main industrial hub for the Tanneries. Effluents from the tanneries are discharged in to streams which drain into ponds, thereby polluting the ground water sources and cultivable land. These values are more than the permissible limit in and around the tannery cluster compared to other parts of the area. The pH,CO3, Na, Ca, Mg, NO3, and SO4 values of all groundwater samples are within the permissible limits but all the EC, TDS, HCO3and K values are exceeding the permissible limit. According to TH and Cl 6 samples are exceeding the prescribed limits. There are about 80 tanneries spread within 4-6 kms radius in the south western part of the town i.e., near Paraipatti, so ground water pollution is very high compared to other places. Madurai road tanneries are located so in Begampur near Annamalayar school pollution is high. R. M. Colony is having the highest household wastages because of its vertical expansion so in that areas also pollution is high.
优质淡水的供应是二十一世纪最关键的环境问题之一(环境规划署，2002年)。城市化导致环境污染，即城市的增长导致贫民窟的增加，固体废物的处理，交通设施的提供，连接和地下水污染。地下水是印度农村和城市地区家庭和农业的重要水资源。地下水污染的来源有很多。地下水污染是一个主要问题，特别是在工业区，特别是像丁迪古尔。城镇内及周边存在大量制革企业及印染、漂白等配套工业单位，是影响城镇环境质量的主要因素。丁迪古镇自1981年以来就没有进行过实际扩张，面积为14.01平方公里。只有病房随着人口的快速增长而增加。丁迪古尔是制革厂的主要工业中心。制革厂的废水排入溪流，流入池塘，从而污染了地下水源和可耕地。与该地区其他地区相比，这些数值超过了制革厂集群内及其周围的允许限值。所有地下水样品的pH、CO3、Na、Ca、Mg、NO3和SO4值均在允许范围内，但EC、TDS、hco3和K值均超过允许范围。根据TH和cl6的检测，样品超过了规定的限值。在城镇的西南部，即Paraipatti附近，有大约80家制革厂分布在半径4-6公里的范围内，因此与其他地方相比，地下水污染非常严重。马杜赖路的制革厂位于阿纳马拉亚尔学校附近的Begampur，污染很高。R. M. Colony的家庭浪费是最高的，因为它的垂直扩张，所以在那个地区污染也很高。

The variety having longer flowering duration was severely infested by bud fly as compared to those with shorter flowering duration.","PeriodicalId":250014,"journal":{"name":"International Journal of Agricultural Invention","volume":"30 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120992641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Alternaria brassicae (Berk.) Sacc., a necrotrophic fungus devastating oilseed Brassica crops in India, causes up to 47% reduction in seed yield. So the study is conducting to develop the knowledge about the variability of A. brassicae in terms of cultural, morphological, pathogenic characters and their effects on different Brassica species of rapeseed mustard, for minimizing the losses caused by A. brassicae and help to stabilize the rapeseed mustard production. In variability study, all the isolates showed cultural, morphological variability. Average conidial length was maximum in isolate Ab2 (21.7μ) followed by Ab4 (20.7μ) and minimum in Ab8 (15.6μ). Septation in conidia, both horizontal and vertical also showed variation in different isolates. Finally it was revealed that smallest size of conidia in isolates Ab8 and longest size of conidia in isolates Ab4 were observed. On solid medium, maximum sporulation was observed in Ab7 followed while minimum sporulation recorded in Ab8. On liquid medium, maximum sporulation was observed in Ab7 while minimum sporulation recorded in Ab8. All the isolates showed the variability in qualitative characters i.e. spot colour, presence or absence of central point, concentric rings and yellow halo and as well as in quantitative characters i.e. incubation period and Percent Disease Index.
