ThesisItem Open Access CROP RESPONSES TO POTASSIUM APPLICATION IN VERTISOL UNDER RICE-WHEAT CROPPING SYSTEM(Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.), 2004) DNYANESH RAMKRUSHNA, BHANDARKAR; MISHRA, V.N.; PATIL, S.K.; DAS, G.K.; LAKHERA, M.L.Crop responses to potassium application in Vertisol were studied in ricewheat cropping system, at Instructional Farm in the Department of soil Science, IGAU, Raipur (C.G.). The objectives of the experiment were (i) to study the crop responses to fertilizer K application in rice-wheat cropping system (ii) to estimate the content and uptake of potassium by rice and wheat. (iii) to evaluate the different K fractions in Vertisol as influenced by rice-wheat cropping system. (iv) to monitor the potassium balance after two successive cropping season. (v) to study the fixation of potassium in Vertisol as influenced by K fertilization at surface and subsurface soil layer. The treatments consisted of five graded levels of fertilizer K application (0, 50, 100, 150 and 200 kg K2O ha-1) in four replication using RBD. The amount of all fractions was higher in surface layer (0-15 cm) than that in sub surface layer (15-30 cm). The order of dominance of different forms of potassium in the soil were non-exchangeable K >exchangeable K>available>water soluble K. The over all changes in different forms of K due to cropping indicates a decreasing trends in available and exchangeable K fractions but water soluble and non-exchangeable K did not show such trends. The initial value for total K (water-soluble + exchangeable + non-exchangeable K) was 1944 kg/ha that increased after rice season up to 2026 kg/ha then decreased to 1927 kg/ha after wheat crop season. No crop responses were observed to K fertilization in terms of yield and K uptake of rice and wheat crops. This indicates that soil under study is sufficient to meet the K requirement of the crops. The potassium balance indicates that application of 100-150 kg K2O/ha can sustain the K fertility status of the soil. Potassium fixation study reveals that the rate of fixation is enhanced in the treatment, which did not received any fertilizer K as compared to that receiving fertilizer K (@ 200 kg K2O ha-1). While comparing K fixation in twosoil depth, indicate that subsurface soil layer had slightly higher fixation as compared to that in surface layer.ThesisItem Open Access DEPLETION AND BUILD UP OF POTASSIUM IN A VERTISOL UNDER RICE-WHEAT SYSTEM AFTER ONE CROP CYCLE(Indira Gandhi Krishi Vishwavidyalaya, Raipur, 2005) BACHKAIYA, VINAY; PATIL, S.K.; MISHRA, V.N.; SARAWGI, S.K.; SAXENA, R.R.Depletion and build up of potassium in a Vertisol under rice-wheat system after one crop cycle, was studied at Instructional Farm in the Department of Soil Science, IGAU, Raipur (C.G.). The objectives of the experiment were (i) to study the crop response to fertilizer K application in rice-wheat cropping system, (ii) to study changes in soil K fractions (iii) monitoring changes in K activity ratio (iv) to monitor potassium balance. The treatments were five graded levels of fertilizer K application (0, 50, 100, 150 and 200 kg K2O ha-1) in four replication using RBD. The amount of all fractions was higher in surface layer (0-15 cm), than that in sub surface layer (15-30 cm). The order of dominance of different forms of potassium in the soil were non-exchangeable K > exchangeable K > available K > water soluble K. The overall changes in different forms of K due to cropping after one crop cycle indicated decreasing trends in available, exchangeable and non-exchangeable K over initial but water soluble fraction did not show such trend. The initial value of total K (water soluble + exchangeable + non-exchangeable K) was 2255 kg ha-1 that increased after rice to 2290 kg ha-1 then decreased to 2123 kg ha-1 after wheat crop. No crop response was observed in terms of yield, content and K uptake of rice and wheat crops. This indicated that K status was sufficient to meet the K requirement of the crops. The negative K balance after one crop cycle indicated that crop removal exceeds K application in all the treatments. Study on changes in K activity ratio revealed that activity ratio increased upto the application of 150 kg K2O ha-1 at both soil depths, however, higher K activity ratio was observed at surface layer than that at subsurface layer.ThesisItem Open Access EFFECT OF ORGANIC AND INORGANIC NUTRIENT SOURCES ON THE QUALITY OF SCENTED RICE(Indira Gandhi Krishi Vishwavidyalaya, Raipur, 2003) DONGARWAR, PRAVEEN KUMAR; DAS, R.O.; PATIL, S.K.; MISHRA, V.N.; SARAWAGI, A.K.; RAI, A.L.A field experiment was carried out in the Department of Soil Science, IGAU, Raipur (C.G.) to study the "Effect of organic and inorganic nutrients sources on the quality of scented rice" in Inceptisol and Vertisol. The results showed that grain yield of rice was significantly affected by soil type and higher yields were obtained on Inceptisol man Vertisol. A significant response of grain yield was also observed due to N, P and FYM application. The effect of FYM application was less marked but its combination with different levels of N and P fertilizer resulted in significant increase in yield. The N and P interaction was also significant. The marginal return was higher than marginal cost upto the N: P combination of 120:80 kg ha"1, considered as profitable dose. Among all physical quality parameters, brown rice length, brown rice L:B ratio, milled rice length, milled rice L:B ratio, head rice recovery, cooked rice length and aroma were higher in Inceptisol, while paddy L:B ratio, milling percentage and protein content per cent were significantly higher in Vertisol. In case of nitrogen fertilization most of the physical quality traits like paddy length, brown rice length, milled rice length remained unaffected, on the other hand milling percentage, head rice recovery, protein content and aroma significantly increased with N, which indicates that nitrogen enriched the grain and reduced the breakage during milling. The effect of P application on all the rice quality parameters was not significant except on protein content. The protein content and aroma were significantly affected by FYM application. The aroma in leaves also increased with high level of FYM. The other quality parameters were not significantly affected by FYM application due to its low nutrient content. The best integrated management strategy identified from this study is 60 kg N ha"1, 80 kg P ha"1 and 5 t FYM ha"1 for obtaining better quality scented rice with higher yields.ThesisItem Open Access EFFECT OF ORGANIC AND INORGANIC SOURCES ON NUTRIENTS ON SOIL FERTILITY AND YIELD OF RICE IN ALFISOL(Indira Gandhi Krishi Vishwavidyalaya, Raipur, 2001) KHATAYATE, MANOJ KUMAR; BAJPAI, R.K.; PATIL, S.K.; GUPTA, S.B.; SHARMA, H.G.; LAKHERA, M.L.ThesisItem Open Access IMPACT OF PUDDLING AND TILLAGE PRACTICES ON SOIL PHYSICAL PROPERTIES AND CROP PRODUCTIVITY UNDER RICE-WHEAT CROPPING SYSTEM IN ALFISOL(INDIRA GANDHI KRISHI VISHWAVIDYALAYA RAIPUR (C.G), 2006-09) SHARMA, CHARU; BAJPAI, R.K.; URKURKAR, J.S.; PATIL, S.K.; TEDIA, K.; LAKHERA, M.L.IMPACT OF PUDDLING AND TILLAGE PRACTICES ON SOIL PHYSICAL PROPERTIES AND CROP PRODUCTIVITY UNDER RICE-WHEAT CROPPING SYSTEM IN ALFISOLThesisItem Open Access IMPACT OF PUDDLING AND TILLAGE PRACTICES ON SOIL PHYSICAL PROPERTIES AND CROP PRODUCTIVITY UNDER RICEWHEAT CROPPING SYSTEM IN ALFISOL(Indira Gandhi Krishi Vishwavidyalaya, Raipur, 2006) SHARMA, CHARU; BAJPAI, R.K.; URKURKAR, J.S.; PATIL, S.K.; TEDIA, K.; LAKHERA, M.L.An experiment was conducted during the kharif and rabi season of 2003- 04 and 2004-05 at Instructional Farm, IGAU, Raipur to investigate the impact of puddling in rice and tillage practices in wheat on soil physical properties and crop productivity under rice-wheat cropping system in Alfisol. In this study, four rice establishment methods (viz. P1 - direct dry seeding, P2 - drum seeding, P3 - manual transplanting, P4 - mechanical transplanting)were used and its residual effect on tillage practices (viz. T1 – conventional tillage, T2 – zero tillage, T3 - strip tillage, T4 - bed planting) adopted in wheat were assessed in respect of changes in soil physical properties, root growth and crop productivity. The soil physical properties viz., bulk density, hydraulic conductivity, infiltration rate, per cent water stable aggregates, mean weight diameter, cracking and drying pattern were significantly affected by different rice establishment methods. Puddling significantly reduced the bulk density of surface layer (0-0.07 m) at initial stage (15 DAT) but at harvesting, the puddled treatments attained significantly higher value than direct dry seeded treatment. The bulk density of sub surface (0.15 – 0.22 m) puddled layer was higher than direct dry seeding and maximum under mechanical transplanting. Further, the hydraulic conductivity and infiltration rate, percent water stable aggregates (WSA > 2.0 mm) and mean weight diameter were reduced significantly in comparison to direct dry seeded rice. Puddled soil had higher water retention capacity and formed wider cracks upon drying as compared to unpuddled plots. At 0-0.10 m depth, the percent root distribution was approximately 8% higher under puddled treatments than direct dry seeding. The root length density, root volume and root dry weight were higher under direct dry seeding treatment in all the depths, at 30 DAT. But, at later stage (70 DAT) these parameters were higher under manual transplanting treatment upto 0.20 m depth. The performance of direct dry seeding was similar to manual transplanting with slight reduction in yield (4.63%). However, the direct dry seeded rice gave higher net returns (5.94%) and benefit: cost ratio (22.64%) than manual transplanting with an advantage of 10.13%, 6.15% and 5.09% in energy output input ratio, energy use efficiency and specific energy, respectively. Among different wheat tillage practices conventional and bed planting significantly reduced the bulk density and increased the hydraulic conductivity and infiltration rate than the zero tillage and strip tillage at the surface layer. However, the percent WSA >2mm and mean weight diameter under zero tillage and strip tillage was higher by 11% and 5% respectively as compared to conventional tillage and bed planting, but effect was non significant. The root length density and root volume was significantly higher in conventional and bed planting upto 0.20 m depth. The wheat grain yield was significantly effected by different tillage practices. The highest grain yield was obtained under conventional tillage and lowest under strip tillage. There was no significant effect of rice establishment methods and wheat tillage practices on the organic carbon, available nitrogen, phosphorus and potassium status of soil during both the years. The direct dry seeding had significant residual effect in improving soil physical properties, root growth and yield of succeeding wheat crop. Under rice wheat cropping system, on the basis of BC ratio, energy output input ratio and energy use efficiency, the performance of direct dry seeding of rice during kharif followed by zero tillage for wheat during rabi stood first. However, direct dry seeding of rice followed by conventional tillage for wheat proved to be more remunerative as compared to the other treatments on the basis of net returns and specific energy.ThesisItem Open Access INFLUENCE OF NITROGEN LEVELS ON GROWTH AND YIELD OF TPS POPULATIONS OF POTATO (Solanum tubersum L.)(INDIRA GANDHI KRISHI VISHWAVIDYALAYA RAIPUR (C.G), 1998-01) ISHAQUE, MOHAMMED; SARNAIK, D.A.; DUBEY, P.; PATIL, S.K.; KUMAR, RAVINDRA; RAI, A.L.; PRASAD, G.V.INFLUENCE OF NITROGEN LEVELS ON GROWTH AND YIELD OF TPS POPULATIONS OF POTATO (Solanum tubersum L.)ReportsItem Open Access STATUS REPORT (2012-13 TO 201-14)(INDIRA GANDHI KRISHI VISHWAVIDYALAYA, KRISHAK NAGAR, RAIPUR 492012, CHHATTISGARH) PATIL, S.K.; URKURKAR, J.S.; LAKPALE, RAJENDRA; NANDEHA, K.L.; NANDA, H.C.; DAVE, A.K.ReportsItem Open Access STATUS REPORT (2014-15 TO 2015-16)(INDIRA GANDHI KRISHI VISHWAVIDYALAYA, KRISHAK NAGAR, RAIPUR 492012, CHHATTISGARH) PATIL, S.K.; URKURKAR, J.S.; LAKPALE, RAJENDRA; DEWANGAN, DEVENDRAThesisItem Open Access A STUDY ON THE EFFECT OF DIFFERENT WATER REGIMES AND N LEVELS ON THE PERFORMANCE OF MUSTARD (Brassica Juncea Linn.
