Abstract: Majority are international migrant and interstate migrants, majority (75%) of the respondents in the age groups (21 to 40) migrated to different places like Thiruppur, Coimbatore, Chennai, Kerala and Saudi, Arabia, Dubai, Mascot, Malaysia, and Singapore. Main reasons for migration are low wages, unemployment debt due to failure in agriculture due to lack of rains, more employment opportunities in the destination place and more jobs and a handsome salary which leads to improvement of the living conditions.Such pull and push factors encourage emigration to high-income countries experiencing labour shortages. Emigration has different impacts on sending country and destination country. Low wages and rain-fed agriculture in the native place have been found the economic factors leading to migration, while poverty, poor civic amenities, leading a poor life, high aspirations and demonstration effect were social and psychological factors resulting to migration. Lesser storage of water in delta region consequent on insufficient rainfall in the catchment area does not allow the farmers to Cauvery Delta Zone.

Six field experiments were conducted at Tamil Nadu Rice Research Institute, Aduthurai to evolve suitable zinc fertilization method for rice - rice (Oryza sativa L.) cropping system in Cauvery delta zone. The treatment includes: T1 : Control, T2 : 100 g zinc sulphate (ZnSO4)/cent in nursery alone., T3 : root dipping alone in 2 % zinc oxide (ZnO) solution, T4 : 25 kg ZnSO4 ha-1, T5 : 37.5 kg ZnSO4 ha-1, T6 : 25 kg ZnSO4 ha-1+ Farm Yard Manure (FYM) 12.5 t ha-1, T7 : 25 kg ZnSO4 ha-1 + Green Leaf Manure (GLM) 6.5 t ha-1, T8 : Tamil Nadu Agricultural University Micro Nutrient (TNAU MN) mixture 25 kg ha-1 as Enriched Farm Yard Manure (EFYM), T9 : TNAU MN mixture 37.5 kg ha-1 as EFYM, T10 : Foliar spray of 0.5% ZnSO4 + 1 % urea at tillering and panicle initiation stage, T11 : 100g ZnSO4 /cent in nursery alone + Foliar spray of 0.5 % ZnSO4 + 1 % urea at tillering and panicle initiation stage (T2+ T10), T12 : root dipping alone in 2 % ZnO solution + Foliar spray of 0.5 % ZnSO4 + 1 % urea at tillering and panicle initiation stage (T3 + T10), T13: 100 g ZnSO4 /cent in nursery alone + root dipping alone in 2 % ZnO solution + Foliar spray of 0.5 % ZnSO4 + 1 % urea at tillering and panicle initiation stage (T2 + T3 + T10). The treatments T5, T6, T7 and T9 were skipped in rabi season to know the residual effect of these treatments in the subsequent season. Among the treatment combinations, application of 25 kg ZnSO4 ha-1 + FYM 12.5 t ha-1 recorded higher grain yield in both kharif (6232 kg ha-1) and rabi (6236 kg ha-1) seasons. The same treatment combination recorded higher Zn content and Zn uptake as well. Regarding soil nutrient content, the same treatment recorded higher N, P and K content. This treatment was followed by application of 25 kg ZnSO4 ha-1 + green leaf manure 6.5 t ha-1. The experimental findings suggested that combination of organic and inorganic sources not only increased the yield but also improves soil health in Cauvery delta zone.

Soil And Water

Rice is a prime food crop for Asian countries. Wet land rice cultivation contributes maximum grain yield than dry land rice. Cauvery delta is a predominant area for rice cultivation in Tamil Nadu. Green algae growth during Kuruvai (June -August) season is a serious problem in wet land rice. These algae growth create anaerobic condition and prevent rice root respiration. The entire rice root was uprooted and floated on the stagnated water during initial stage. There is no preliminary study for green algae control in rice field. Soil and water samples were collected and analyzed for the nature of occurrence. Laboratory and field experiments were conducted to find out the remedial measures. The results of soil and water sample analysis showed that use of bore well water and dumping of phosphatic fertilizers leads to salt accumulation which favours the green algal growth. The results of the laboratory experiment revealed that the CuSO4 londox power, propiconazole and hexaconazole showed moderate inhibition on 5th day after treatment. The findings from field experiment indicated that use of conoweeder, alternate wetting and drying and CuSo4 drenching @ of 2.5 kg/ha when green algae appearance has just noticed or 5.0 kg/ha when severe growth occurred was effective in managing the green algae. Among all measures, alternate wetting and drying is the best management practices. CuSO4 drenching reduces around 70% of the growth. Even though CuSO4 react negatively with algae growth, soil pH changes and salt concentration play a major role on the CuSO4 action towards green algae. In order to maintain soil health condition, biofertilizer application, crop rotation, green manure trampling to be practised to recover the soil from alkaline pH, removal of accumulated salt and to control the algae growth using CuSO4.

Effects of age on the distribution of specific life events experienced during the past year by community-based adults were examined controlling for sex, race, education, marital status, and place of residence. The controlled analyses were done using logistic regression. Data were gathered via personal interview from 3,798 respondents ages eighteen years and over who participated in the Epidemiologic Catchment Area (ECA), community survey from North Carolina. Respondents were placed in one of four age groups. The percentage of respondents reporting each of the nineteen events examined ranged from 0.5 percent for death of spouse to 19.1 percent for death of loved one. Age was an important predictor in the controlled analysis for thirteen of the seventeen life events examined. A majority of differences occurred between the youngest and oldest age groups. Age differences were not found for illness of one week or more involving activity limitation.

Background: Adolescents represent about 21.8 percent of India’s population. Various health risks with potentially life-threatening consequences become prominent in this age group. This study was undertaken with the objective to determine the morbidity profile of school going adolescents in Tamil Nadu.Methods: This descriptive, cross sectional study was planned and conducted from January 2016 to August 2017. The study population included 987 adolescent boys and girls aged between 10 to 19 years studying in high and higher secondary Government schools of Thiruvallur district of Tamil Nadu. Semi-structured questionnaire was used as data collection tool.Results: The mean age groups of this school going adolescent are 14.2 yrs. In the present study 583 (59%) of the study participants were affected by one or more morbidity condition. Among them, 395 (67.7%) were in the age group 10-14 years and 188 (32.2%) in the age group 15-19 years. 122 (21%) and 461 (79.1%) of male and female were affected respectively. In the present study, fever (21%) was the commonest reported morbidity followed by acute respiratory infection (15.7%) and acute gastrointestinal disease (13. 4%).Conclusions: This study shows that adolescents are prone to a wide range of morbidity conditions. Apart from respiratory and gastro intestinal diseases, reproductive tract infections and sexual health problems are important morbidities affecting this age group. There is strong need to sensitize health care practitioners at all levels, in both government and private sectors towards health problems in adolescent age groups.

Purpose The purpose of this study is to assess the effects of demographic groups (i.e. gender groups, marital status groups, age groups, income groups, experience groups, education groups and occupation groups) on socially responsible consumption (hereafter SRC) behaviour. Design/methodology/approach The study was carried out in Chennai city, the capital of Tamil Nadu state of India. A total of 214 responses were collected during the survey. The respondents were the university staff composed of lecturer/professor, lab instructor, admin staff and support staff. A socially responsible purchase and disposal scale has been used to measure SRC behaviour amongst consumers. The convenience sampling technique was used for data collection. Independent-samples t-test and one-way analysis of variance (ANOVA) techniques were used for hypotheses testing. Findings Factor analyses confirmed the multidimensional structure of the SRC construct with the following axes: firms’ internal corporate social responsibility (hereafter CSR) performance, firms’ external CSR performance, firms’ environmental CSR performance and consumers’ personal social responsibility. In addition, this study found that demographic groups have no effects on SRC behaviour. Research limitations/implications The current research will be a step forward to a richer and more inclusive understanding of the effects of demographic groups on SRC behaviour. Practical implications This study would help managers to understand consumer markets, formulate strategy and develop sustainable products. Originality/value This study is amongst the few attempted to examine the effects of demographic groups on SRC behaviour amongst consumers. This research endeavoured to validate the multidimensional nature of the SRC construct.

Casuarina equisetifolia is an exotic, fast growing, multipurpose tree species grown in Tamil Nadu. Altogether, about 40 species of insects have been recorded on C. equisetifolia in Tamil Nadu State. Among them, the bark eating caterpillar, Indarbela quadrinotata is considered as the most destructive pest in plantations. Wide variation in the infestation levels of bark eating caterpillar was noticed in Casuarina plantations grown under four agro-climatic zones of Tamil Nadu; the Cauvery Delta Zone showed highest intensity of attack, followed by the North Eastern Zone and the Southern Zone in the decreasing order of infestation, while the High Rainfall Zone was not affected by the pest. Plantations of younger age suffered from higher levels of infestation, compared to that of older ones. Among the climatological parameters, the minimum temperature had significant positive correlation with the pest infestation. Apart from the naturally occurring entomopathogenic fungus, Beauveria bassiana, the botanical formulations such as Melia azedarach seed kernel extract (5%), Pongamia pinnata seed oil (5%), Hydnocarpus pentandra seed oil (10,000 ppm) and Neem oil (5%) were found to be very effective in managing the pest under field condition.
