Abstract:
A two years field study according to split plot design was conducted to investigate the impactof crop residue (CR) incorporation and P application (0, 40, 80, 120 kg P2O5/ha) on P use efficiency andyield of direct seeded rice (DSR) and wheat grown under saline soil (ECe = 4.59 dS/m; pHs = 8.38;SAR = 6.57 (mmolc/L)1/2; extractable P = 4.07 mg/kg; texture = sandy clay loam), during the years 2011and 2012. Planting of DSR (with and without crop residue incorporation @ 2 tonnes/ha) were placed inmain plots and P application was in sub plots. Data on tillering, plant height, panicle length, 1000 grainweight, paddy and straw yields were collected. On an average of two years, maximum tillers (18), paniclelength (33), grain/panicle (121) and paddy yield (3.26 t/ha) were produced with P application @ 80 kgP2O5/ha along with CR incorporation. Similarly in case of wheat grown after DSR, maximum tillers (17),spike length (17), grains/panicle (66) and grain yield (3.56 t/ha) were produced with P application @ 80 kgP2O5/ha along with CR incorporation. Although, the growth and yield contributing parameters with thistreatment (80 kg P2O5/ha + CR) performed statistically equal to 120 kg P2O5/ha without CR incorporationduring both the years, but on an average of two years, grain yield of DSR and wheat was significantlysuperior (22 and 24%, respectively) than that of higher P rate (120 kg/ha) without CR. Overall, continuoustwo years CR incorporation further increased (17%) paddy yields during the follow up year of crop harvest.Higher P use efficiency and concentrations of P, K+ and Ca2+ in both DSR and wheat plant tissues wasfound where 80 kg P2O5/ha was applied along with CR incorporation or 120 kg P2O5/ha alone while Na+and Mg2+ concentration decreased with CR incorporation and increasing P rate. An increasing trend inDSR paddy and wheat grain yields was observed with increasing the rate of P application without CRincorporation, however, it was not as much as that of 80 kg P2O5/ha application with CR incorporationand found to be superior than rest of the treatments during both study years.

Abstract:
A field experiments was conducted during 2015 and 2016 to study the effect of green manures and phosphorus levels in blackgram crop at Agricultural College Farm, Bapatla. The experiment was conducted in split- split plot design on sandy clay loam soil with three main treatments three subtreatments to Kharif rice and three sub-sub treatments to Rabi crop. The treatments consisted of Dhaincha green manure crop, sunnhemp green manure crop and without green manure as main plot treatments and three phosphorus levels to rice crop comprising of 45 kg P2O5 ha-1, 60 kg P2O5 ha-1 and 75 kg P2O5 ha-1 as sub- plot treatments and are replicated thrice. The Rabi experiment was laid out on the same site in a split-split plot design without disturbing the soil for succeeding blackgram crop and each of the Kharif plot was divided into three sub-sub plots to receive three levels of phosphorus (No P, 50% RDP and 100% RDP) to each plot. Yield and economics of blackgram which received Dhaincha green manure incorporation with 75 kg P2O5 ha-1 to Kharif rice crop and 100% RDP to Rabi blackgram was recorded significantly higher and it was on a par with sunnhemp green manure incorporation with 75 kg P2O5 ha-1 to Kharif rice crop and 100% RDP to Rabi blackgram.

Abstract:
The uptake of phosphorus was found to increase with each successive increase in nitrogen level from 200 to 300 kg ha-1 and up to 60 kg ha-1 with increase in age of the crop with higher uptake at 300 kg N ha-1 and 60 kg P2O5 ha-1. Crop sown in N3P3 (300 kg N + 80 kg P2O5 ha-1) recorded significantly higher phosphorus uptake by grain. Higher nutrient uptake was recorded in F2 (125% of F1) and F4 (F2+ Kharif crop residue incorporation), while the sub plot F1 (Recommended dose of N and P2O5) and F3 (F1+ Kharif crop residue incorporation) recorded lower nutrient uptake during both the years. The uptake of phosphorus by maize increased with each successive increment of nitrogen and phosphorus but the trend is not consistent. The higher level of nutrients supplied through increased dose of nitrogen along with phosphorus is conducive for extensive root proliferation, to explore a greater volume of soil and absorb larger quantities of nutrients. Enhanced uptake of nutrients often tends to correlate positively with dry matter production and concentration of nutrients in the plant under higher level of nutrient supply. Residues of corn did not affect the P uptake and the nutrients released from corn residue is not a major contributor for subsequent corn nutrient uptake in sandy loam soils as is evidenced with highest nutrient uptake in the plots received with 125 % recommended dose either with or without residue incorporation.

Abstract:
The investigation was carried out during summer season to know the effect of different organic and inorganic fertilizers on physicochemical properties of soil & content and uptake of plants. The experiment was laid out in factorial randomized block design (FRBD) followed by twelve treatments with four replications. Water holding capacity, bulk density, porosity of soil was not significantly influenced by application of organic and inorganic fertilizers at harvest. Application of vermicompost @ 1.0 t ha-1 recorded significantly higher nitrogen content & uptake in seed and stover and potassium content in stover of green gram which was at par with incorporation of FYM @ 4 t ha-1 but phosphorus content & uptake was not significantly influenced by either incorporation of FYM or vermicompost or inorganic fertilizer. The use of 100% RDF (20 kg N + 40 kg P2O5 ha-1) resulted in significantly higher uptake of nitrogen and potassium by seed, stover and total uptake by crop and were at par with the application of 75% RDF (15 kg N + 30 kg P2O5 ha-1). Nitrogen, phosphorus and potassium content & uptake in seed, stover and total uptake of green gram was significantly higher recorded with the incorporation of FYM @ 4 t ha-1 which was at par with application of vermicompost @ 1 t ha-1. Application of farm yard manure @ 4 t ha-1 or vermicompost @ 1 t ha-1 along with inorganic fertilizers @ 75% RDF (15 kg N + 30 kg P2O5 ha-1) is best suited for improving physico-chemical properties of soil and nutrients content & uptake of green gram.

Abstract:
Field experiments were conducted to study direct and residual effect of P-sources and organic manures on rice. Green leaf manuring increased the yield and nutrient uptake by rice. The increase in grain yield with the addition of GLM + URP @ 60 kg P2O5 ha-1 over URP @ 60 kg P2O5 ha-1 were 31 per cent in the fertilized plots and 27.9 per cent in the residual plots. Combined application of GLM and P @ 60 kg P2O5 ha-1 irrespective of the P source increased the nutrient uptake by rice. A drastic reduction of value : cost ratio at higher level of fertilizer P application, irrespective of the P sources was recorded. The additional expenditure on incorporation of poultry manure was the highest which dropped the value : cost ratio considerably.

Abstract:
Field experiment was conducted with treatment shedule included four levels of N, three levels of P2Os, combination of two levels on N and P2O5 as a inorganic source and four levels of FYM as organic source applied through soil in rabi season. The results indicated that the incorporation of FYM at 40, 30, 20 cart loads/ha were found effective in minimising the incidence of root rot and increasing the grain yield of safflower. Application of nitrogen in combination with phosphorus at optimum doses of 50 N + 25 P20s and 25 N + 12.5 P20s kg/ha also were found effective in reducing the root rot and thereby increasing the grain yield. However, when these inorganic amendments applied singly were found ineffective.

Abstract:
A field study was conducted during rabi season of 2022 at Maize Research Centre, Professor Jayashankar Telangana State Agriculture University, Agricultural Research Institute, Rajendranagar, Hyderabad, Telangana. The experiment comprised of 12 treatment combinations laid out in a split–plot design with three replications. The main–plot treatments included four different tillage practices:M1-Conventional tillage (Plough + Cultivator + Rotovator), M2-Residue incorporation (After 10 days of spreading the haulms, only rotovator was run), M3- Residue incorporation (After spreading the haulms, microbial consortium was sprayed and after 10 days only rotovator was run) and M4- Zero-tillage (only microbial consortium was sprayed on the haulms). Sub–plot treatments included three nutrient levels: N1- 100% RDF (240-80-80 N-P2O5-K2O kg ha-1), N2: 100% RDN & P and 50% RDK (240-80-40 N-P2O5-K2O kg ha-1), and N3: 87.5% of RDN, 75% RDP and 75% RDK (210-60-60 N-P2O5-K2O kg ha-1). Results revealed that, among the tillage practices, residue incorporation (M3) had recorded significantly higher growth attributes like plant height, leaf area, dry matter production and chlorophyll content (SPAD) at 30, 60 DAS and at harvest stages and yield of maize and it was on par with zero-tillage (M4) whereas all the parameters were significantly lower in conventional tillage (M1). Among the different nutrient levels, N1(100% RDF) had shown significantly superior performance in terms of growth attributes and yield of maize and it was on par with N2 (100% RDN & P and 50% RDK) whereas N3(87.5% of RDN, 75% RDP and 75% RDK) recorded significantly lower growth attributes and yield of maize .The interaction effect due to tillage and nutrient levels on plant height, leaf area, dry matter production, chlorophyll content (SPAD) at 30, 60 DAS and at harvest and yield was non- significant.

Abstract:
Ce travail de thèse s’inscrit dans le projet DEM’N’MELT dont le but est de vitrifier des déchets de moyenne ou haute activité issus du démantèlement d’installations nucléaires. Les compositions de déchet considérées dans ce manuscrit, riches en P2O5, MoO3 et ZrO2 et dont l’activité résulte essentiellement du 137Cs, sont basées sur celles des déchets générés par le démantèlement de l’usine UP1 de Marcoule. Leur principale caractéristique est leur variabilité de composition. L’objectif est d’étudier l’incorporation de ces déchets dans un verre aluminoborosilicaté riche en alcalins à 1100 °C.Le premier axe d’étude consiste à se placer dans un système proche du système industriel (11 oxydes). Il a mis en évidence que MoO3 et P2O5 sont les deux principaux constituants du déchet conduisant à des séparations de phases et/ou des cristallisations. Celles-ci peuvent, dans le cas des phases molybdates, contenir du Cs. Aux teneurs envisagées, ZrO2 s’incorpore quant à lui dans la matrice sans générer d’hétérogénéités.Le deuxième axe se concentre sur l’étude structurale et microstructurale des mécanismes d’incorporation de P2O5 et MoO3 dans un système simplifié (6-7 oxydes). Ces éléments sont tout d’abord considérés seuls puis incorporés conjointement. Il apparaît que P et Mo s’insèrent majoritairement sous forme d’entités isolées (PO43- et MoO42-) du réseau vitreux et que leur incorporation conjointe augmente la tendance à la cristallisation du système
This work belongs to the DEM’N’MELT project, which is dedicated to the vitrification of intermediate or high level radioactive wastes coming from the dismantling of nuclear facilities. The waste compositions of this study, rich in P2O5, MoO3 et ZrO2 which activity is mainly due to 137Cs are close to the ones of the shutdown UP1 facility (Marcoule). Their main feature is the variability of their composition. This work objective is to study the incorporation of these wastes in an aluminoborosilicate glass rich in alkali oxides at 1100 °C.The first part of the study will be dedicated to a system close to the industrial one (11 oxides). It highlights that MoO3 and P2O5 are the main waste constituents responsible for phase separation or crystallization. Moreover, molybdate crystalline phases can contain Cs. ZrO2 is incorporated in the glassy matrix without leading to heterogeneities.Then, a simplified system (6-7 oxides) is studied along with the structural and microstructural incorporation mecanisms of P2O5 and MoO3. These oxides are first considered alone and then added simultaneously. This second study highlights that P et Mo mainly lead to the formation of entities isolated from the glassy network and that their simultaneous addition increases the crystallization tendency

Abstract:
We have fabricated rare-earth-doped SiO2-P2O5 planar films on silicon substrate by using flame hydrolysis deposition, incorporating the rare-earth ions by an aerosol doping technique, for the first time to our knowledge. Rare-earth-doping levels in the glass were dependant on the nebulized solution strength and the delivery rate of the aerosol to the torch. The aerosol doping technique has the advantage over solution doping of directly incorporating the rare-earth ions into the soot during the deposition and giving control of the doping profile through the film by contolling the transfer of the aerosol to the torch during the deposition. The aerosol doping technique is described, as well as the fabrication and optical assessment of channel waveguides with a view to realizing waveguide lasers. Moreover, the long term goal is to accomplish mono­lithic integration of active and passive optical components. This may be achieved by selective area doping of planar films. The method of selective area doping is discussed for aerosol doping.

Abstract:
Experiments were designed and performed to analyse the cytoskeleton assembly and the interaction of glycoprotein (GP)IIb, IIIa and cytoskeletal proteins during platelet activation. A23187 stimulated 125I labeled platelets were solubilised with Triton X-100 solution and centrifuged. The insoluble fraction were analysed by two dimensional electrophoresis and the soluble fraction were fractionated with 5-25% sucrose gradient centrifugation and analysed by SDS PAGE. In Triton X-100 insoluble fraction, high molecular weight protein fraction(MW > 106) was present after stimulation which were consisted of actin binding protein(ABP), myosin heavy chain(MHC), actin and GPIIb and IIIa. And some of the ABP and MHC formed dimer. ABP and actin in this fraction were decreased with 1 mM CaCl2 treatment but the reduction of ABP was inhibited by leupeptm. In Triton X-100 soluble fraction after stimulation, some of the ABP, MHC, P235 protein, actin and small amount of GPIIb, IIIa were sedimented in the same high density fraction but most proteins were sedimented as a monomer form or GPIIb-IIIa complex form. The GPIIb, IIIa incorporation in high molecular weight protein fraction or high density fraction was absent in Ca++ chelating condition or the presence of competitive fibrinogen binding inhibitor which blocked the platelet aggregation. It is concluded that cytoskeletal proteins and GPIIb, IIIa are assembled each other and formed high molecular weight protein fraction or dimer formation during activation. In stimulated platelets these assembled cytoskeletal proteins containing GPIIb, IIIa were also found in Triton X-100 soluble fraction as a precursor of high molecular weight fraction in Triton X-100 insoluble fraction. The binding of fibrinogen to GPIIb-IIIa complex induce the linkage of GPIIb, IIIa to assembled cytoskeletal proteins.
