ThesisItem Open Access “ATTITUDE OF FARMERS REGARDING ADOPTION OF CONTROL MEASURE PRACTICES OF VARIOUS DISEASES OF RICE CROP IN DHAMTARI DISTRICT OF CHHATTISGARH STATE”(Indira Gandhi Krishi Vishwavidyalaya Raipur, 2005) Shrivastava, Rajiv; Shrivastava, K.K.; Sarkar, J.D.; Trimurty, V.S.; Sharma, M.L.; (Smt.) Shukla, SindhuThe present study was carried out during 2004-05 in two selected blocks of Dhamtari district. Sixteen villages were randomly selected and data were collected through personal interview method from 160 respondents collected data were analyzed by using appropriate statistical methods viz. mean, percentage, S.D. correlation and multiple regression were applied for the interpretation of data. The socio-personal and economic profiles of the respondents revealed that majority of the respondents belonged to middle age group (36 to 55 years) educated upto high school and higher secondary level, belonging to other backward class, medium size of family, participated in more than two organization, involved in farming + business as their main occupation and cooperative bank as their main source of credit facilities. The neighbour/ friends/ farmer/ relatives/ gramsevak, shop keeper and television were the important sources to them, majority of the respondents were having medium extension contact. Scientific orientation, knowledge, moderately favourable attitude towards use of control measure practices of various rice diseases. The majority of the respondents were found in medium level category regarding use of control measure practices of various rice diseases. They were adopting the practices such as deep ploughing, summer ploughing, resistant variety, early sowing, proper planting distance, weed removal, fertilizer management, seed treatment, chemicals they do not adopt the biological and mechanical control methods. The major problems faced by the respondents were lack of knowledge about appropriate selection of fungicides, lack of knowledge about appropriate doses of fungicides, dealers are selling spurious agrochemicals, high cost of fungicides and complicated procedure of seed treatment, the major suggestions were also given by the respondents. Training should be given regarding different control measure practices of various rice diseases, availability of fungicides with subsidized rate at locally spurious agrochemicals should be strictly banned and proper precautions should be taken during the spraying and use of fungicides. Among the selected characters viz., education, size of family, social participation, land holding, occupation, annual income, credit facilities, sources of information, extension contact, knowledge, scientific orientation, adoption were found significant in relation to attitude of the respondents regarding adoption of control measure practices of various rice diseases and accounted 55.4 per cent variability. Age, caste and mass media exposure were showed non significant relation with the attitude of the respondents in adoption of control measure practices of various rice diseases.ThesisItem Open Access Comparative efficacy of botanical and chemical insecticides against the sucking pests of potato (solamon tuberosum linn.)(jnkvv, jabalpur, 1999) Shrivastava, Rajiv; Bharaj, G. S.ThesisItem Open Access PROTEOMIC STUDIES OF SEED PROTEINS IN RICE (Oryza sativa L.)(INDIRA GANDHI KRISHI VISHWAVIDYALAYA RAIPUR (Chhattisgarh), 2021) Brijlal, Bagul Rameshwar; Prasad, Archana S.; Verma, Sunil K.; Shrivastava, Rajiv; Saxena, Ravi R.In the present research work, the 40 genotypes of rice (Oryza sativa), were fractionated and characterized based on the protein fraction and the total protein and quantifies with the Coomassie Reagent Protein Assay and biochemical characters (sodium dodecyl sulfate polyacrylamide gel electrophoresis, SDS-PAGE). The research work conduct in the Department of Molecular Biology and Biotechnology, Raipur during 2017-2018. The research work shows the differences among rice genotypes based on rice fraction (prolamin and glutelin) and total protein. Rice seed protein is localized in two types of protein bodies (PB) PB-Ι and PB- ΙΙ. PB-Ι contains prolamin. Whereas PB-ΙΙ is rich in glutelin and globulins. PB-Ι is less digestive than PB-ΙΙ suggesting that prolamin in PB-Ι is nutritionally less meaningful for humans than glutelin in PB-ΙΙ (Jiang et al. Proteome science, 2014, 12:51). In Glutelin Protein fraction, among of selected genotypes Ir-64 (6.20 mg/g), Gp-145-70 (5.31 mg/g), GP-145-48 (5.17 mg/g) calculated higher percentage. The elaychi verity also having a good percentage level of glutelin which also observe in SDS PAGE. Also in Prolamin protein fraction, Swarna (0.12 mg/g), R-RGM-ATN-47 (0.14 mg/g), R-RHP-IM-84 (0.17 mg/g), IET-24780 (0.21 mg/g) calculated the less percentage than the other selected genotypes. In Percentage of total protein IR-64 (7.66 mg/g), Kalam Gurmatia (7.47 mg/g), GP-145-48 (7.46 mg/g), Kalokuchi (7.31 mg/g) are higher than the other selective genotypes. Also, the 15 verities treated with nitrogen doses with control, 40kgha-1, 60kgha-1, and 100kgha-1, Form the observation 100kgha-1 nitrogen dose more effective than other lower and higher doses respectively. These rice verities mainly having more nutritive value than other selective verities due to the low percentage of prolamin (Hyun et al., 2013). On the prolamin protein fraction SDS page, the 15 kD band is less intense observe in verity WR-2, moti basmati, WR-3, R-RGM-AS-40, and very less intense in verities M-1433, Botaki gurmatia, WR-1, and WR-132 respectively. In our work, obtained SDS PAGE shows the nunki gurmatia and Botaki gurmatia having low intense glutelin acidic subunits bands. In glutelin protein fraction SDS page, RR-149, M-1433, WR-1, IC-116076, Niwari, WR-73, WR-132, malpa, Surmatia, GP-145-66, R-RGM-AS-41, R-RHP-IN-87, R-RHP-IM-84 and IET-24780. N2 doses rice germplasm show the variation in bands and get less intense in total protein SDS page. In total protein SDS PAGE, as the Nitrogen doses increase the glutelin acidic subunits and prolamin bands goes less intense banding pattern. There are slight changes in the intensity of the bands on the variation on nitrogen observe in SDS PAGE. From the percentage of protein and SDS PAGE banding pattern we conclude, some rice genotypes have more nutritious than other genotypes. As per observation rice genotypes having different nutritional abilities. Overall the IR-64 (6.20 mg/g), GP-145-70 (5.31 mg/g), GP-145-48 (5.17 mg/g) in glutelin protein fraction, Swarna (0.13 mg/g), R-RGM-ATN-47 (0.14 mg/g), R-RHP-IM-84 (0.17 mg/g), IET-24780 (0.21 mg/g) in prolamin protein fraction respectively. These rice genotypes are further used for the enhancement of the nutritional quality of rice.
