According to census 2011, the population of tribes stood at 104 million in India constituting 8.6% of the nation’s total population. Of these 7 lakh tribes are in Tamil Nadu with 6 lakh in rural and a lakh in urban. The decadal change in rural-urban population of tribes are 19.8 per cent in rural and 34.2 per cent in urban. Kanyakumari district was chosen for the study since the decadal change of tribal population is very tremendous than any other district. (5.1 per cent in rural and 88.2 per cent in urban) The study was undertaken among the Kanikaran tribes of the district by selecting four highly populated tribal settlements through Proportionate Random Sampling technique. The sample for the study consisted of 100 respondents (40 from Thachamalai, 39 from Arukani, 15 from Puravilai and 6 from Vellambi malai tribal settlements). The data were collected as push and pull factors with a well-structured and pre-tested interview schedule and analysed by Garett Ranking Technique. Employment availability (72.80) took the first rank in active pull factors of migration followed by high income and working conditions (67.20). The tribal migrants placed high value on employment related factors. Threat from wild life (77.48) and lack of employment in their locality (70.52) were the active push factors reported by the tribal migrants. The other factors like declining trend in agriculture (57.08) and poverty (54.92) were also considered as crucial factors by a considerable percentage of respondents. The policy implications drawn out of the findings of the research study such as fencing of tribal settlements, encouragement of self-employment among tribes, introduction of successful agricultural technologies, implementation of forest act, 2006 and formation of migrant labour unions can be taken into consideration for limiting the distress migration of tribes and hence retain them for the betterment of traditional agriculture.

Twenty-five lines of rice which were introgressed for root traits and water use efficiency (WUE) were physiologically characterized for drought adaptive traits in the present study. These lines along with the parents were screened for yield and other trait performance under semi-irrigated aerobic cultivation. Leaf temperature was selected as surrogate for root traits and SCMR for WUE. Apart from these traits, yield and yield associated traits, relative water content (RWC), membrane stability index and chlorophyll content were measured. The lower leaf temperature of trait introgressed lines than IR-64 suggests lines have better root biomass which enabled them to maintain its temperature. The yield performance of trait introgressed lines were better than recurrent parent, IR-64 under semi-irrigated aerobic cultivation. It indicates that the introgression of the respective traits onto an elite background, IR-64 improved the efficacy of the introgressed lines under water limited condition. Comparative analysis of introgressed lines for drought adaptive traits suggested G 25, G 4, G 12 and G 18 performed better than other lines. Therefore, these lines introgreseed for drought tolerance traits could be utilized for other breeding programs for further improvement in drought tolerance in rice for the development of elite genotypes.

Results revealed that majority of the (36 years to 58 years) middle aged (56.66%), followed by illiterates (25.88%), medium (4 to 6 members) family size (69.58%), 11-20 years of agricultural labourer experience (42.08%), no farm experience (20.00%), marginal land holding (50.00%), marginal tenant landholding (36.66%), wage + agriculture (44.66%) main occupation, medium urban contact (70.83%), medium deferred gratification(72.50%), medium credit orientation (71.66%), medium achievement motivation (62.50%), medium economic orientation (60.84%), medium selfconfidence (67.51%), medium achievement motivation (62.50%), of the agricultural medium level of aspiration (55.41%).","PeriodicalId":13334,"journal":{"name":"Indian Journal of Pure & Applied Biosciences","volume":"45 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79187538","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}
In the present investigation, estimates of genetic variability, heritability and genetic advance were assessed for thirteen different characters in the F3 population derived from nine groundnut crosses viz., TLG 45 x ICGV-05155,JL – 501 x KDG-128, K-1641 x ALR-3, SG-99 x R-8808, ALG-234 x ICGV-00350, AG-24 x ICGV-6110, JSSP-LS-58 x CS-19, TPG-41 x GG-16 and J-89 x ISK-I-16-13.The mean sums of squares due to genotypes and parents were significant for all the characters except shelling outturn (%) and mean sums of squares due to F3s were significant for all the characters except 100-matured kernel weight, oil content (%) and biological yield per plant and mean sum of square due to parents vs crosses were significant for all the characters except shelling outturn, kernel yield, 100-matured kernel weight, oil content (%) and harvest index indicating there by sufficient amount of variability was present in the material studied. The estimates of GCV were quite close to the PCV were moderate to high in most of the crosses for all the characters except in days to appearance of first flower, days to maturity, oil content and biological yield per plant. High heritability coupled with high genetic advance and high value of GCV and PCV for number of matured pods per plant in Cross 7 (JSSP-LS-58 × CS-19). Thus, it can be concluded that this Cross 7 for number of matured pods per plant was mainly under the influence of additive gene action and selection would be effective for improving these traits.

Since green revolution crop fertilization has become one of the major components for crop production. The major drawbacks with conventional fertilizers are that they were highly prone to losses, low nutrient use efficiency and causes environmental pollution. Efforts to increase NUE of conventional fertilizers have not shown any considerable outcome. So, there is a need to intervene with alternate technology, among them nanofertilizers have the potential to increase NUE. Synthesis and application of macroutrient nanofertilizers at reduced recommendation enhances nutrient release pattern and increases the growth, yield and NUE of crops. Similarly, Seed treatment and foliar application of micronutrient nanofertilizers enhances crop nutrient uptake that leads to increased yield and NUE of crops. It also enhances quality parameters of the crops. Nanomaterial enhanced fertilizers loaded with plant nutrients enhanced nutrient release pattern and increasing plant uptake efficiency and reduce the adverse impacts of fertilization application.
