ThesisItem Open Access SORPTION STUDIES ON P, K, Cu, Mu, zn, S AND B IN VERTISOL, INCEPTISOL AND ENTISOL SOILS(MAHATMA PHULE KRISHI VIDYAPEETH, RAHURI - 413 722, DIST.AHMEDNAGAR, MAHARASHTRA, INDIA, 01-01-00) Achyutrao, Bhosale Amol; Patil, Dr.Y.M; Patil, Dr.J.D; Patil, Dr.A.S; ADSULE, Dr.R.N; Karrppa, Dr.S.MSorption behaviour of P, K, Cu, Mn, Zn, S and B were studied for representative soil orders viz., Vertisol (Otur), Inceptisol (Sawargaon) and Entisol (Pargaon) soils of C.C. Farm of M.P.K.V., Rahuri. All these soils were alkaline in reaction, calcareous in nature and clay to sandy clay loam in texture. Equilibration studies revealed that at low levels of equilibration, maximum amount of each element was sorbed on all the soils. Vertisol soil was found to possess high sorption capacity, followed by Inceptisol and Entisol soil. To assess the balanced nutrition of Pearl millet (Jaint Bajra) a pot culture study was conducted in three soils representing low to high sorption capacity. The results showed that the dry matter yield as well as per cent relative yield were significantly influenced by the balanced nutrition applied on the basis of sorption capacity of soils. The magnitude of N, P, K, Zn, S and B limiting the yield of test crop were estimated in all three soils. The clay, CaC03 Organic carbon, cation exchange capacity were found to be the main important soil factors which govern the sorption behaviour of Vertisol (Otur), Inceptisol (Sawargaon) and Entisol (Pargaon) soils of M.P.K.V., Rahuri.ThesisItem Open Access SORPTION OF ORTHOPHOSPHATE AND PYROPHOSPHATE BY AMMONIATED TROPICAL SOILS(MAHATMA PHULE K R I S H I V I D Y A P E E TH ( AGRICULTURAL UNIVERSITY ) DEPARTMENT, 01-06-77) T a m be, Kumar Nivruti; Savant, N.K; Zende, G.K; Patil, B.BThesisItem Open Access A STUDY ON WATER MOVEMENT AND N AVAILABILITY AS INFLUENCED BY WATER APPLICATION RATES AND N LEVELS UNDER PITCHER IRRIGATION FOR CABBAGE (Brassica oleracea Var.

Capitata, L.) in black soil (vertisols)" was conducted on black clayey soil (pH 8.1, EC 0.4 mmhoa/cm, FC 42 % and PUP 22 %) during rabi season of 1984 at Water Management Project, MPAU, Rahuri. The irrigation treatments comprised of application of water at the rate of 0.5, 1.0, 1.5 and 3.0 l/day through pitcher and irrigation scheduled at 50 cm CPE (6.0 cm depth) with three nitrogen levels (recommended dose of 60 kg/ha, 70 % and 40 % of recommended dose). Nitrogen fertilizer was applied in the form of urea through pitcher and compared with surface application. An experiment was conducted in RBD with 4 replications. Application of Water through the pitcher at the rate of 3.0 l/day was found significantly superior (38.50 t/ha) to rest of the irrigation treatments but treatment of 1.5 l/day uas on par (37.01 t/ha) with respect to cabbage yield. There uas water saving to the extent of 51.86 per cent uhen treatment of 1.5 l/day water application (CU = 202.2 mm) was compared with the control treatment of irrigation scheduled at 50 mm CPE (CU = 377.0 mm). Water use efficiency under treatment of 1.5 l/day application was 183 kg/ha-mm consecutively there was increase in the yield of 34.2 per cent uhen compared with control treatment. Yield uas significantly reduced when N fertilizer dose uas reduced to 40 per cent. The yield of recommended dose (32.90 t/ha) and 70 per cent reduction (32,32 t/ha) were significantly superior but were on par with each other. There was saving in N fertilizer to the extent of 18 kg/ha due to adoption of pitcher irrigation method for water application. Soil water movement studies showed that wetting front was moved to the extent of 60 and 80 cm for vertical and horizontal directions respectively uhen water was applied at the rate of 1.5 l/day. Unsaturated hydraulic conductivity showed exponential relation with increase in volumetric water contents.ThesisItem Open Access STUDIES ON THE QUALITY OF IRRIGATION WATER WITH REFERENCE TO SOIL CHARACTERISTICS IN JUNNAR TAHSIL OF PUNE DISTRICT(MAHATMA PHULE KRISHI VIDYAPEETH, RAHURI- 413 722, DIST. AHMEDNAGAR, MAHARASHTRA STATE, (INDIA), 01-12-04) SOMASHEKHAR; Patil, Dr.Bhardas.P; Surve, Dr.S.P; Shinde, Dr.D.B; Tuse, Prof. B.PThe objective of the present investigation was to Study the quality parameters of irrigation water and its influence on soil chemical characteristics and temporal variation of water and soil properties from Junnar tahsil of Pune district. The water and soil samples were collected during month of June 2003, October 2003 and February, 2004 and analysed for their different chemical properties. Among the quality parameters of irrigation waters, pH of all water samples was found alkaline in nature. The electrical conductance showed, about 11.78 per cent samples were found good category and 70.58 per cent samples were found permissible and only 17.64 per cent samples were found doubtful category for crop production. Among the cations Na+ was predominant cation followed by Ca"^, Na+, K+ whereas in anionic concentration, it was observed that SO4" was predominant followed by CI" and HC03" and CO3" were in traces. As per the SAR and RSC ratings these irrigation water were found to be suitable for crop production. As per the temporal variation in irrigation water is concerned, pH showed highest value in October month whereas EC was highest in June and lowest in October. The trend of total cations and anions were as similar to EC. The temporal variations in pH and EC of soil showed no much variation. The cation concentration was highest in the month of June and was lowest in the month of October. In irrigated soils, pH of irrigation water showed significantly positive correlation with soil pH, Ca2+, Mg+2, and Na+ and trends were similar for EC of water also. The exchangeable Ca of irrigation water had positive influence on soil pH, EC, soil Ca2+, Mg+2, and Na+. The Mg2+ and Na+ also showed significant correlation with soil pH, EC, Ca2+, Mg+2. RSC showed significantly negative correlation with all soil chemical properties.ThesisItem Open Access EFFECTS OF APPLICATION OF UREA N, FYM AND THEIR COMBINATIONS ON PHYSICO-CHEMICAL PROPERTIES OF VERTISOL AND YIELD OF FORAGE MAIZE (Zea mays L.)(MAHATMA PHULE KRISHI VIDYAPEETH, Rahuri 413 722 Dist. - Ahmednagar MAHARASHTRA (INDIA), 01-12-99) KISANRAO, NIKAM VAIBHAV; Jagtap, Dr.B.K; Narkhede, Dr.P.L; Ghugare, Dr.R.V; Sabale, Dr.R.NAn investigation entitled/'Effect of application of N through urea and FYM and their combinations on physico chemical properties of vertisol and yield of forage maize (Zen mays L.)u was laid out in completely randomised block design with six treatments and four replications at the Agricultural College, Pune during rabi, 1997, and was conducted in pot culture. Pot culture study revealed that the application of FYM and urea, alone and in combinations significantly improved the physical properties of soil under study. Application of FYM and urea, alone and in combinations revealed significant increase in EC, organic carbon, available N, P and K contents of soil under study where as the pH of the soil decreased significantly. The dry matter yield of maize showed significant improvement due to application of nitrogen through FYM and urea, alone and in combinations as compared to control at all the stages of study. N, P and K concentration in maize and their uptake at different growth stages of maize under study were significantly increased due to application of FYM and urea alone and in combinations. Nitrogen use efficiency of maize was significantly increased due to applied nitrogen through FYM and urea alone and in combinations as compared to maize without N.ThesisItem Open Access STUDIES ON HEAVY METALS UPTAKE AND ITS EFFECT ON YIELD OF CARROT(MAHATMA PHULE KRISHIVIDYAPEETH, RAHURI, DIST. AHMEDNAGAR, MAHARASHTRA STATE (INDIA), 02-07-04) T. R, MR. SRINIVASA MURTHY; Patil, Dr.Bhardas.P; Surve, Dr.S.P; Patil, Dr.G.D; Jawale, Dr.S.MA pot culture experiment was conducted at Department of Agricultural Chemistry and Soil Science, Agriculture College, Pune, during rabi season, year, 2003, with view to study heavy metals uptake and its effect on yield of carrot by using cadmium, lead, nickel and chromium levels @ 0, 2.5, 5, 7.5,10 and 12.5 mg kg'1. The results indicated that the application of cadmium, nickel and chromium at higher levels (> 7.5 mg kg"1) showed significant influence in the dry matter yield. The least shoot dry matter yield of carrot was observed in cadmium followed by chromium and nickel. However, highest reduction in root dry matter yield was recorded in chromium followed by nickel and cadmium. Effect of heavy metals on root growth revealed that application of cadmium at greater than 5 mg kg"1 decreased root length. However, nickel and chromium decreased the same at higher concentration (>7.5 mg kg" ). Root girth was increased at higher concentrations (> 10 mg kg" ) of heavy metals. Application of heavy metals had significantly influenced its uptake and nutrients. Nickel increased nitrogen content in carrot, chromium and nickel increased phosphorus uptake in plants. Whereas, application of lead and cadmium decreased phosphorus content in crop. Potassium content was also decreased by cadmium and chromium application. Nickel and cadmium were accumulated more in crop as compared to lead and chromium. Heavy metals were accumulated more in root portion as compared to shoot portion. Heavy metals did not effect soil pH, EC and organic carbon. From the study it was noticed that the application of heavy metals significantly influenced nitrogen fractions, available potassium, phosphorus and heavy metals in the soil. At harvest of the crop, significantly decreased in the nitrogen fractions were observed due to application of cadmium followed by lead, chromium and nickel. Application of heavy metals at higher concentrations (7.5 to 12.5 mg kg'1) invariably decreased available phosphorus and potassium content in soil. Available heavy metals concentration in soil were recorded high with the application of inorganic salts of heavy metals. Cadmium and nickel metals were available more in soil as compared to lead and chromium, which undergone fixation. At higher concentrationSjCadmium and nickel decreased microbial population in the soil.ThesisItem Open Access STUDIES ON THE QUALITY ASSESSMENT OF WELL WATERS WITH REFERENCE TO SOIL CHARACTERISTICS IN HAVELI TAHSIL OF PUNE DISTRICT(MAHATMA PHULE KRISHI VIDYAPEETH, RAHURI-413 722, DIST. AHMEDNAGAR, MAHARASHTRA STATE. (INDIA), 02-12-04) BHAGWAN, REHPADE SUSHILKUMAR; Surve, Dr.S.P; Patil, Dr.B.P; Bhosale, Prof.A.NAn investigation entitled "Studies on the quality assessment of well water with reference to soil characteristics in Haveli tahsil of Pune district" was carried out during the year 2003-2004. Irrigation water samples from different wells were collected for quality appraisal. The soil samples from irrigated and adjoining unirrigated field were also collected from Haveli tahsil to study the effect of these irrigation water on the soil chemical properties. The total 51 samples were collected in three intervals i.e. July 03, November, 03 and April, 04 and analysed for various constituents. The water samples were analysed for various water quality parameters and constituents viz., pH, EC, cations (Ca""", Mg"1^, Na+, K+), anions (C03"\ HC03', Cl", S04~) and boron. The water samples were found saline to sodic in nature and sodium as cation and sulphate as anion were dominant in well water sample. From the constituents derived parameters like SAR, RSC and Kelley's ratio were estimated. The average values of pH, EC and SARjw were 7.99, 2.82 dSm'1 and 7.49 (mmol L"')1/2 5 respectively. The RSC values of irrigation water samples were ranging from -8.37 to 1.39 meL"1. According to the criteria for the suitability of irrigation water the classes were of following order. C3S1 > C2S1 > C4S1. Continuous use of such quality water without drainage and soil management practices may lead to the saline and sodic soils, particularly in the soils with impeded drainage properties. The average boron concentration noticed in water samples was under permissible limit for most of the irrigation water analysed (0.66 ppm). An experiment was conducted to simulate the effect of this water on chemical properties of soil. Among the soil parameter, the pH of both irrigated and unirrigated soil was moderately alkaline in nature. The EC of unirrigated soils was higher than EC of irrigated soil. Among the exchangeable cations, Ca^ was predominant and fallowed by Mg^, Na+ and K+ in both irrigated and unirrigated soils. In irrigated soils EC of the water showed significantly positive correlation with exchangeable Ca+\ Mg++, Na+ and K+. The TSS and boron content of water significantly and positively correlated with EC, exchangeable Ca44", Mg^, Na+ and K+.ThesisItem Open Access EFFECT OF IRRIGATION SCHEDULING AND N FERTIGATION THROUGH DRIP ON N MOVEMENT, GROWTH, YIELD AND QUALITY OF SEASONAL SUGARCANE(MAHATMAA PTHhUesLisE S uKbRmIiSttHedI tVoI DthYeA PEETH RAHURI, 413 722 DIST - AHMEDNAGAR. Maharashtra State (India), 03-02-95) Kada, Bharat JBatsabu; Ghugare, Dr. R.V; Sonar, Dr. K.R; Bankar, Prof. M.C; Pol, Prof. P.SThe field experiment on "Effect of irrigation scheduling and N fertigation through drip on N movement, growth, yield and quality of seasonal sugarcane" was conducted at the Co-ordnated Project for Research on Water Management, Mahatma Phule Krishi Vidyapeeth, Rahuri, Dist. Ahmednagar during the year 1993-94. The experiment was laid out in a split plot design with three replications. The twelve treatment combinations formed from four irrigation treatments viz., surface irrigation scheduled at 75 mm CPE, drip with two days, three days and four days interval as mainplot treatments and three levels of nitrogen viz., recommended dose of N, 75 per cent N of the recommended dose and 50 per cent N of the recommended dose as sub plot treatments. The gross and net plot sizes were 7.2 x 6.0 m^ and 3.6 x 5.0 m , respectively. The soil of the experimental field was medium deep black with clay in texture, non saline and alkaline reaction. The soil was low in available N, medium in available P and rich in available K. The fertilizer N movement in soil was observed in both directions i.e. vertically and laterally from the emitter source, after two weeks of 2nd and 4th dose of Napplication. The mean values of NH4-N and NO3-N content of soil were higher in drip irrigation than surface irrigation. The treatment drip with two days interval had shown maximum concentration of NH4-N (50.2 ppm) and NO3-N (63.5 ppm) in the 0-20 cm soil layer two weeks after 2nd dose of N application. Reverse trend was observed under surface irrigation i.e. higher concentration observed at lower depth of 40-60 cm (NH4-N 38.3 and NO3-N 48.8 ppm). Average content of NH4-N and NO3-N values were low at the emitter source increased up to 30 cm and declined with increasing the distance from the emitter source. The growth parameters such as plant count, plant height, number of internodes and average girth were not influenced significantly by scheduling of irrigation. However, drip irrigation with two days interval had shown maximum total height (314.3 cm) and mi 11 able height (271.0 cm), average girth (8.98 cm), number of internodes (23.13) and average cane weight (1.68 kg) at harvest. The highest cane (155.7 t ha ) and commercial cane sugar (18.02 t ha ) yields were recorded in the drip irrigation at two days interval with 19.4 and 25.3 per cent increase in cane and commercial cane sugar yields over surface irrigation treatment, respectively. The interval of water application through drip had not shown any significant adverse effect on cane and commercial cane sugar yield. However,the treatment of water application through drip at four days interval had shown 6.2 and 3.6 per cent reduction in cane and commercial cane sugar yields over two days interval, respectively. The cane juice quality in respect of brix, nonreducing sugar, reducing sugar and purity coefficient was not adversely affected due to scheduling of irrigation to sugarcane. The treatment of drip irrigation with two days interval had given significantly higher dry matter accumulation of 42.09, 91.35, 346.7 and 665.7 q ha-1 and N uptake of 67.84, 116.3, 304.9 and 316.8 kg ha-1 at tillering, earthing up, grand growth and harvest stage of sugarcane crop. The surface irrigation scheduled at 75 mm CPE had shown maximum vertical and horizontal root distribution as compared to drip irrigation. In drip irrigation the roots were concentrated in the wetted zone of 0-30 cm, thereafter showed decline in the trend with increasing distance from the emitter source. Application of water at two days interval had given maximum dry roots of 218.7 and 171.1 g m~ ^ in the surface layer of 0-15 and 15-30 cm depth, respectively. The total depth of water applied was considerably low (93.2 cm) in drip irrigation as compared to surface irrigation (166.0 cm), with the saving in irrigtion water to the extent of 43.9 per cent. Drip irrigation with two days interval had given low cosumptive use of moisture 108.6 cm with maximum water use efficiency of 14.34 q (ha cm) x than rest of the irrigation treatments. Application of recommended dose of N had shown the maximum content of 46.6, 40.1 and 31.1 ppm NH4-N and 57.3, 54.1 and 49.3 ppm of NO3-N at 0-20, 20-40 and 40-60 cm soil depth. The NH4-N and NO3-N were low at the emitter source, increased upto 30 cm and then declined with increasing distance. Same trend of results observed during 4th dose of N application. The growth parameters such as plant count, plant height and number of internodes were not influenced significantly by the levels of nitrogen. However, the girth of cane at harvest (9.03 cm) was significantly high in recommended dose of N. The cane and commercial cane sugar yields were significantly influenced by the levels of nitrogen. The application of recommended dose of N gave significantly higher cane and commercial cane sugar yields of 156.0 and 17.60 t ha with an increase of 14.5 and 11.1 per cent over 50 per cent of recommended dose of N, respectively. The cane juice quality in respect non reducing sugar and reducing sugar were significantly influenced by the levels of nitrogen and the application of 50 per cent of recommended dose of N gave significantly high non reducing sugar (17.02 per cent) and significantly low reducing sugar (0.41 per cent) indicating better juice quality. The application of recommended dose of N had shown significantly higher dry matter accumulation of 41.68, 87.23, 402.6 and 642.7 q ha-1 and N uptake of 66.19. 108.7, 298.5 and 304.3 kg ha at tillering, earthing up, grand growth and harvest stage of sugarcane crop than the lower dose of N application, respectively. The interaction effects due to scheduling of irrigation and nitrogen levels were absent. The drip irrigation at two days interval with recommended dose of N applied through drip to seasonal sugarcane is benificial to obtain higher cane and commercial cane sugar yields.ThesisItem Open Access THE PHOSPHORUS_SOLUBALIZATION ABILITY OF SOUIL DIPARTMENT OF AGRO _CLAMATIC ZONE OF THE(MAHATMA PHtJLE KRISHI VIDYAPEETH, 03-08-72) RUDRAKSHA, G.

The treatments receiving full recommended dose of N and P through UNP (19:19:0) and ANP (23:23:0) proved to be better in influencing plant height at all the stages of crop growth. Nitrogen applied to sunflower through urea was found to be efficient in uptake of N at 30 ,and 45 day of crop growth while at 15 day, the highest uptake of N was observed in treatment receiving full recommended dose of N and P through UNP (19:19:0), The treatment receiving full recommended dose of N and P through UNP (27:9:0) found to be efficient in uptake of N at harvest. The uptake of P by the sunflower was found to be enhanced by the treatment receiving full recommended dose of N and P through urea and SSP at 15 ,30 and 45 days of crop growth. At harvest, the treatment receiving full recommended dose of N and P through UNP (27:9:0) was found to be efficient. The uptake of K by the sunflower was found to be enhanced by the treatment urea at the earlier growth stages (i.e. up to 45 day), while at harvest, the treatment receiving full recommended dose of N and P through UNP (27:9:0) was found to be efficient in enhancing K uptake by sunflower. In residual studies, the treatment receiving full recommended dose of N and P through urea and SSP was found t o be efficient in dry matter production and uptake of N by maize at 65 day after sowing. However, treatment receiving full recommended dose of N and P through UNP (27:9:0) proved t o be efficient in uptake of K by raaize at harvest.ThesisItem Open Access Effect Of Varying Soil Salinity On Chlorosis And Growth Of Sugarcane (Saccharum Officinarum, L.)(Mahatma Phule Agricultural University Rahuri, (Dist: Ahmednagar) Maharashtra State. India, 05-05-86) Turkane, P. M; Somawanshi, R.B; Patil, N.D; Ramashis, D.GA pot culture experiment was conducted on a saline soil to observe the effect of leaching on soil properties, chlorophyll content of leaves and dry matter yield of plant tops and roots of sugarcane (Cv. Co-740)• The experimental soil was collected from the farmers' field where sugarcane crop showed severe chlorosis right from the emergence upto the maturity. Plastic pots of 15 litres capacity were filled with 13 kg soil and leached with different quantities of water to create different levels of salinity. The sugarcane plants were grown for 145 days. Leaching of a saline soil with increasing quantity of canal water significantly improved the sugarcane growth as evidenced by increase in the number of tillers per plant and size and weight of the third leaf from the top of the mother plant. The leaf and root-Fe + chlorophyll and dry matter yield of sugarcane increased with the increasing leaching of soil without adversely affecting the soil properties.ThesisItem Open Access PERFORMANCE OF DIFFERENT RABI CROPS GROWN IN DIFFERENT SOIL MOISTURE STORAGE CAPACITIES UNDER RECEDING SOIL MOISTURE CONDITIONS(MAHATMA PHULE KRISHI VIDYAPEETH (AGRICULTURAL UNIVERSITY), 06-03-78) PHULE, G.

It indicated that the application of pressmud (5 t/ha) plus pyrites (2 t/ha) had beneficial effect on reducing chlorosis in sugarcane due to increased availability of nutrients in saline calcareous soil and 2 + active Fe and total chlorophyll content in sugarcane crop.ThesisItem Open Access EFFECT OF FERROUS SULPHATE APPLICATION THROUGH SOIL WITH AND WITHOUT FYM ON THE AVAILABILITY OF IRON IN SOIL AND YIELD OF UPLAND RICE (Oryza sativa, L.)(MAHATMAl PHULE AGRICULTURAL UNIVERSITY,, RAHURI, ( Dist.-Ahmednagar ) ( MAHARASHTRA ), 08-05-86) Durgude, Anil G.; Sonar, K.R; Deore, B. P; Daftardar, S.YA field experiment was conducted on medium black calcareous soil (vertic ustropepts) on rice cv.Karjat 184 during the kharif 1985 at the Post Graduate Instructional Farm, Mahatma Phule Agricultural University, Rahuri. The objective was to study the effect of application of ferrous sulphate through soil with and without FYM on the release of iron and phosphorus in soil and their uptake and yield in upland rice. (Oryza sativa, L.) The soil had pH 8.65. organic carban 0.49%, CaC03 equivalent 8.0%, Olsen-p 18.2 kg/ha and DTPA extractable Fe 2.55 ppm. The result showed that the application of ferrous sulohate and FYM decreased the pH slightly (8.65 to 3.52} nd increased the specific conductance of the soil. The application of ferrous sulphate @ 20 kg/ha recorded the highest concentration of Olsen-P (24.05 kg/ha) and DTPA - Fe (3.71 ppm) in soil at tillering stage. An addition of FYM @ 5 t/ha further increased the concentration of Olsen-P and DTPA - Fe in soil at all the growth stages of rice. The application of ferrous sulphate and FYM significantly increased the dry matter yield at all the growth stage- of rice. The highest dry matter yield of 39.75 q/ha was recorded at harvest stage and addition of FYM further increased the dry matter to 42.82 q/ha. The higher uptake of P (11.82 kg/ha) was observed at flowering stage while highest uptake of Fe (589.16 q/ha) was recorded in straw at harvest stage due to application of FYM and ferrous sulphate, respectively. In general the..increasing trends in uptake of Fe and P by rice was observed.at all the growth stages of rice…It is, thus, evident from the present study that application of ferrous sulphate and FYM is essential on.medium black calcareous soil for the increased concentrationof Olsen-P and DTPA -Fe in soil and their uptake and yield of uoland rice.ThesisItem Open Access INFLUENCE OF F.
