ThesisItem Open Access IMPACT OF MARI GO ROUND RAILWAY LINE COAL DUST OF NTPC, SIPAT ON SOIL PROPERTIES AND YIELD OF RICE CROP(Indira Gandhi Krishi Vishwavidyalaya, Raipur, 2019) Verma, Geeteshwar Singh; Sao, Yushma; Anurag; Patel, J.R.; Saxena, R.R.The present study entitled“Impact of mari go round railway line coal dust of NTPC, Sipat on soil properties and yield of rice crop”was undertaken Barrister Thakur Chhedilal College of Agriculture and Research Station in Bilaspur district of Chhattisgarh during 2018-19. One hundred forty four composite soil samples were taken around the studied area (railway line, NTPC) from different locations (cropped, forest and mixed zone) along with left and right side as well as with four distances from the track (10 m, 500 m, 1000 m and 1500 m) with depth of 0-15 cm at before sowing and after harvest of crop to analyze the bulk density, particle density, soil texture, porosity percentage, soil pH, electrical conductivity, organic carbon percentage, available nutrients (N, P, K, S, Fe, Mn, Cu, Zn, B) as well as heavy metals (Cd, Cr, Co, Ni, Pb and As). The microbial population (bacteria, actinomycetes and fungi), soil microbial biomass carbon, carbon fractions (very labile, labile, less labile and non-labile) and yield of the rice crop grown under the cropped zone were recorded. The experiment was laid out in a factorial randomized block design with three factor and three replications with main objectives i.e., to monitor the changes in important soil properties (physical, chemical and biological) due to coal dust deposition around mari go round railway line, to study the labile, non-labile carbon fractions and soil microbial biomass carbon of the collected soil sample of the study area, to evaluate the impact of coal dust on rice yield of farmer’s field. The data of different characters were collected and analyzed, and results found are discussed here. The bulk density was more at 10 m distance of the studied area while porosity percentage was low at that point. The silt and sand content of the soil were more at closer site (10 m) than control site (1500 m) which turns soil into sandy clay loam to silty clay loam. The available N, P, K, S, B, Fe, Mn, Cu and Zn content of the soil were higher at closer site (10 m distance) than the control site (1500 m distance). Colony farming unit of bacteria, fungus and actinomycetes were higher at closer site (10 m) along with the soil microbial biomass carbon. The labile and very labile fractions of the carbon were also higher at 10 m site of the studied area. The forest zone had more microbial population along with the organic carbon percentage, soil microbial biomass carbon, fractions of carbon (very labile, less labile and labile carbon) and available nitrogen than the other zones while cropped zone had more micronutrients than the other zones of studied area. Most of the heavy metal content in soil was recorded non-significant with different factors of studied area and no regular trend was recorded for heavy metal content. The yield of the rice crop in cropped zone was low in closer site (10 m) of the studied area than the control site (1500 m).ThesisItem Open Access FORMULATION OF CUSTOMIZED FERTILIZER FOR CROP YIELD MAXIMIZATION IN VERTISOLS AND INCEPTISOLS OF MUNGELI DISTRICT OF CHHATTISGARH(Indira Gandhi Krishi Vishwavidyalaye, Raipur, 2018) Sushma; Sao, Yushma; Mishra, V.N.; Shukla, R.K.; Lakhera, M.L.A pot culture experiment was conducted in the Department of Soil Science and Agriculture Chemisrty, BTC College of Agriculture and research, Bilaspur, during Kharuf seasion 2017-18. "Formulation of customized fertilizer nutrients for crop yield maximization in vertisols and inseptisols of Mungeli district of chhattisgarh" . using two reprentative soils(vertisols and inseptisils) collected from village Mungeli (vertisols) and Jhanjpurikal (inceptisols) of the Mungeli districc. The objectives of the study were o identify the specific nutrients which limit the crop yield throught rice yield throught rice response using nutrients omission technique during kharif season, 2017 and to demonstrate the optimum use of identified limiting nutrients and it’s comparison with farmer’s fertilizer practice with wheat crop during rabi season, 2017-18.The treatments constituted with application of all nutrients applied at optimum level known as All (SSNM dose) while in others, one of the nutrient elements from all the nutrient treatments (All) was omitted. There were eleven treatments for each type of soil and three replications with completely randomized design. All treatments werecommon for both the soils exceptomission of Fe and Mn in case of VertisolandomissionofCa and Mg in case of Inceptisolwere kept keeping the concept of soil reaction.After addition of all treatments, rice (“rajeshwari”) was transplanted in three hills/pot with 3 seedlings in each hill.The treatments constituted with application of all nutrients applied at optimum level known as SSNM dose while in others, one of the nutrient elements from all the nutrient treatments was omitted. The soil reaction (pH) of the Vertisol was at 7.6 and that of Inceptisolexhibited 6.9. Both the soils were low in,organic C, available N, S, and available P, high status in available K, exchangeable Ca and Mg. The micronutrient status of the soils were above critical level specially high status in Fe, Mn and Cu level except B and Zn in Vertisol and Inceptisol.The grain yield reductions were more pronounced with N and P omission as by N was 37.81% and 32.71%, while P omission caused a yield reduction of 27.05 % and 25.23% inVertisols and Inceptisols. Omission of Zn (T9) reduced the grain yield only in Vertisols. The straw yield reductions were more pronounced with N and P omission.The percent reductions in straw yield by N 31.35 % and 35.78 %, while P omission caused a yield reduction of 28.48 % and 28.70 % inVertisolsandInceptisols. With respect to N, P, K uptake by rice in both the soils under study, indicated an identical performance with dry matter production (grain and straw yields) as the nutrient uptake is the multiple of content and grain and straw yields. Like grain yield performance, N, P and K uptake also affected severely with N, followed by P and S omission treatments. The effect on other treatments, no remarkable variations were observed except Zn and B omitted treatments in case of Vertisol. Highest Ca, Mg and S uptake in Vertisol were recorded in the treatment receiving all nutrients i.e. 66.76, 38.79 and 17.92 mg/pot, respectively and that in Inceptisol as 63.13, 36.37 and 17.89 mg/pot, respectively and statistically at par with those of other treatments except N, P and S omitted treatments. Like other major and secondary nutrients, similarThesisItem Open Access DEPLETION AND BUILD UP OF POTASSIUM IN A VERTISOL UNDER SUGARCANE CROP AFTER FIFTH CROP CYCLE(INDIRA GANDHI KRISHI VISHWAVIDYALAYA RAIPUR(C.G), 2009-08) Narayan, Nasare Manoj; Sengar, S.S.; Mishra, V.N.; Porte, S.S.; Choudhary, Tapas; Lakhera, M.L.DEPLETION AND BUILD UP OF POTASSIUM IN A VERTISOL UNDER SUGARCANE CROP AFTER FIFTH CROP CYCLEThesisItem Open Access WATER USE, WATER USE EFFICIENCY AND PRODUCTIVITY OF LINSEED(Linum usitatissimum L.)IN RELATION TO DIFFERENT METHODS OF SOWING(INDIRA GANDHI KRISHI VISHWAVIDYALAYA RAIPUR(C.G), 2004-02) Vitthalrao, Mohod Prashant; Tedia, K.; Sharma, R.B.; Singh, A.P.; Mishra, B.P.; Saxena, R.R.WATER USE, WATER USE EFFICIENCY AND PRODUCTIVITY OF LINSEED(Linum usitatissimum L.)IN RELATION TO DIFFERENT METHODS OF SOWINGThesisItem Open Access WATER REQUIREMENT AND NITROGEN USE EFFICIENCY OF SUNFLOWER (Helianthus annuus L.)AS INFLUENCED BY IRRIGATION AND NITROGEN LEVELS(INDIRA GANDHI KRISHI VISHWAVIDYALAYA RAIPUR(C.G), 2004-09) Balaji, Mohature Yogesh; Tedia, K.; Ganjir, B.L.; Chandrakar, B.L.; Lakhera, M.L.WATER REQUIREMENT AND NITROGEN USE EFFICIENCY OF SUNFLOWER (Helianthus annuus L.)AS INFLUENCED BY IRRIGATION AND NITROGEN LEVELSThesisItem Open Access CROP RESPONSES TO POTASSIUM APPLICATION IN VERTISOL UNDER RICE-WHEAT CROPPING SYSTEM(INDIRA GANDHI KRISHI VISHWAVIDYALAYA RAIPUR(C.G), 2004-09) Ramkrushna, Bhandarkar Dnyanesh; Mishra, V.N.; Patil, S.K.; Das, G.K.; Lakhera, M.L.CROP RESPONSES TO POTASSIUM APPLICATION IN VERTISOL UNDER RICE-WHEAT CROPPING SYSTEMThesisItem Open Access TRANSFORMATION OF ADDED P AND K INTO VARIOUS INORGANIC FRACTIONS UNDER INTEGRATED NUTRIENT MANAGEMENT(INDIRA GANDHI KRISHI VISHWAVIDYALAYA RAIPUR (C.G), 2006-10) Joshi, Amit; Das, R.O.; Mishra, V.N.; Saxena, R.R.; Bajpai, R.K.TRANSFORMATION OF ADDED P AND K INTO VARIOUS INORGANIC FRACTIONS UNDER INTEGRATED NUTRIENT MANAGEMENTThesisItem Open Access FERTILIZER RECOMMENDATION BASED ON SOIL TEST FOR RICE IN INCEPTISOL AND VERTISOL OF CHHATTISGARH(INDIRA GANDHI KRISHI VISHWAVIDYALAYA RAIPUR (C.G), 2003-09) Arya, Vivak Manohar; Das, R.O.; Sharma, R.B.; Mishra, V.N.; Bhambri, M.C.; Saxena, R.R.FERTILIZER RECOMMENDATION BASED ON SOIL TEST FOR RICE IN INCEPTISOL AND VERTISOL OF CHHATTISGARHThesisItem Open Access DEPLETION AND BUILD UP OF POTASSIUM IN A VERTISOL AFTER THIRD CROP CYCLE UNDER RICE-WHEAT CROPPING SYSTEM(INDIRA GANDHI KRISHI VISHWAVIDYALAYA RAIPUR (C.G), 2007-09) Baghel, Vinod Kumar; Srivastava, L.K.; Das, R.O.; Tuteja, S.S.; Lakhera, M.L.DEPLETION AND BUILD UP OF POTASSIUM IN A VERTISOL AFTER THIRD CROP CYCLE UNDER RICE-WHEAT CROPPING SYSTEM
