ThesisItem Open Access Changes in soil properties under fruit tree species in semi-arid zone(CCSHAU, Hisar, 2023-05-25) Gull, Ishrat; Sharma, Manoj KumarThe present study, entitled "Changes in soil properties under fruit tree species in semi-arid zone" was carried out in 2022-2023 at the experimental farm of the Department of Horticulture, CCSHAU, Hisar, with the objective to study the effect of fruit tree species on physical, chemical and biological properties of soil. Soil samples were collected from four fruit tree species and bare site (control) at four depths (0-15, 15-30, 30-60, 60-90 cm) to analyse different soil properties. Experiment was laid out in RBD design with four replications. Four fruit tree species namely Mangifera indica, Psidium guajava, Syzygium cuminii and Aegle marmelos were selected for the study. The results of the present investigation showed that nutrient levels were higher at the surface layer (0-15 cm) of soil and decreased with increasing depth. Soil pH and EC reduced significantly under jamun and guava orchards by 5.8% and 81.9%, respectively over control. Highest pH and EC was recorded in mango orchard. Jamun orchard recorded highest OC, N, total N, S and DTPA extractable Fe, Mn, Zn while the available P, K, total P, K, DTPA extractable Cu were found to be highest in bael orchard. Soils under bael orchard recorded the highest total Fe, Mn and Cu content while as total Zn was found to be highest in soils under guava orchard. MBC and dehydrogenase activity increased by 43.8% and 71.8% in jamun, 41.4% and 59.3% in bael, 39.6% and 54.6% in guava and 33.5% and 53.1% in mango over control. Highest percent increase in alkaline phosphatase and urease activity was by jamun (45.8% and 40.3%), followed by bael (38.3% and 39%) and lowest in control. Highest bulk density and penetration resistance was observed in mango orchard and lowest in jamun orchard. Highest water holding capacity was recorded in jamun (40.6%), followed by bael (38.8%), guava (38.5%) and mango (36.3%).ThesisItem Open Access Designing a CD-ROM for awareness about abortion in dairy animals(Guru Angad Dev Veterinary and Animal Sciences University, Ludhiana, 2015) Sharma, Manoj Kumar; Verma, H.K.Increased awareness of the dairy farmers about correct managemental practices is the most limiting factor determining the productivity and profitability of an enterprise. Effective communication between extension workers and dairy farmers is required to tackle the constraints at its initial level. The communication devices which can overcome the literacy barrier and engage multiple senses of the user, are best suited for maximum results. Audio visual aids are the best choice to achieve this target attributing to their multiple advantages. Present study entitled Designing a CD ROM for awareness about abortion in dairy animals was conducted to develop a video based instructional device for farmers. This was evaluated for knowledge gain by the dairy farmers before and after exposure to it. The multimedia elements of the developed CD-ROM were found appropriate in conveying the required message by the subject matter experts. There was 81.18 % knowledge gain about general terminology and causes while a gain of 63.44 % was recorded in knowledge of respondents about management, control and prevention measures of abortion in dairy animals. Overall, there was 71.77 % knowledge gain among the respondents about all aspects of abortion in dairy animals. The CD-ROM was assigned a final rating score of to be 3.87 out of 4 by the experts, finding it as an effective mean to deliver the message to the viewers. Therefore, the developed CD-ROM credibly performed its function of increasing the awareness of the farmers about abortion in dairy animals and will enhance their production efficiency and profitability positivelyThesisItem Open Access Effect of phosphorus applications under different types of salinity in tomato(CCSHAU, 2016) Pooja Rani; Sharma, Manoj KumarTwo screen house experiments were conducted to study the relative tolerance of tomato (Var. Hisar Arun) and interactive effect of phosphorus with different types of salinity on tomato crop. In first experiment, the treatment consisted of two types (Cl- and SO42- dominated) with the four levels 0, 2, 4, 6 and 8 dS m-1 of salinity. In the second experiment, interactive effect of different phosphorus levels (0, 12.5, 25 and 50 ppm) with chloride and sulphate dominated salinity was investigated on yield, fruit quality and nutrient content of tomato. Both the experiments were replicated thrice in a completely randomized design and the desired types of salinity were created using chloride and sulphate salts of the Na+, Ca+ and Mg2+. Salinity induced early flowering in tomato and this advancement was more pronounced in chloride dominated salinity as compared to sulphate dominated salinity. With the increasing salinity levels from 0 to 8 dS m-1 there was a decrease in the plant height, number of fruits, yield and mineral composition of tomato. SO42- salinized plants had better vegetative growths as compared to that of Cl- salinized plants. The overall reduction of fresh fruit yield at an ECe of 2, 4, 6 and 8 dS m-1 under Cl- and SO42- dominated salinity was 8.1 and 3.4, 26.4 and 16.2, 40.0 and 28.1 and 51.5 and 42.5 per cent, respectively as compared to non-saline conditions. Thus there is more than 50% yield reduction at 8 dS m-1 in chloride salinity. There was a significant increase in TSS, firmness, ascorbic acid and titratable acidity of tomato fruit with increasing level of salinity due to water and ionic stress created by both types of salinity. However, values of all these fruit quality parameters decreased with increased application of P due to stress mitigation by P under saline soil conditions. The increased levels of P from 0 to 50 ppm in soil resulted in increase of both growth and fruit yield of tomato irrespective of types and levels of salinity. Cl-1 content of plants decreased and N, P, K and SO42- content of plant was increased with application of P. A synergistic relationship between P and SO42- and an antagonistic one between P and Cl-1 ions was established. The mean ECe, water soluble Na+, Ca+, Mg2+, Cl- and SO42- increased with increase in the salinity level from 0 to 8 dS m-1 and these increasing concentrations in soil affect the tomato crop. These concentrations decreased significantly as applied P increased in soil. Therefore, P mitigates the effect of salinity.ThesisItem Open Access Effect of zinc applications under different types of salinity in wheat(CCSHAU, 2014) Sonia Rani; Sharma, Manoj KumarTwo screen house experiments were conducted to study the relative tolerance of wheat (Var. KRL-210) and interactive effect of zinc with different types of salinity on wheat crop. In first experiment, the treatment consisted of two types (Cl- and SO4 -2 dominated) with the four levels 0, 4, 8 and 12 dS m-1 of salinity. In the second experiment, interactive effect of different zinc levels (0, 5, 10 and15 ppm) with chloride and sulphate dominated salinity was investigated on yield and uptake of wheat. Both the experiments were replicated thrice in a factorial completely randomized design and the desired types of salinity were created using chloride and sulphate salts of the Na+, Ca+ and Mg2+. Germination of wheat delayed was more in chloride dominated salinity at 8 and 12 dS m-1 as compared to sulphate dominated salinity. No effect at 0 and 4 dS m-1 in both types of salinity in germination. With the increasing salinity levels from 0 to 12 dS m-1 there was a decrease in the biomass, grain and straw yield of wheat. However, the magnitude of decrease in the wheat yield resulted from the increase in salinity. There was a decrease in mean grain yield of wheat from 9.12 to 6.41 g pot-1 and 9.41 to 7.17 g pot-1 in chloride and sulphate dominated salinity, respectively, as salinity levels increased from 4 to 12 dS m-1. The reduction in grain yield, biomass and chlorophyll ‘a’ and chlorophyll ‘b’ was more in case of chloride dominated salinity as compared to sulphate dominated salinity. The increased levels of Zn from 0 to 15 ppm in soil resulted in increase of both grain and straw yield by 34.1and 36.7 per cent, respectively, over non saline soil. The mean Zn uptake across all the salinity levels decreased from 93.95 to 68.05 μg pot-1 (27.6%) and 109.87 to 78.43 μg pot-1 (28.6%) in chloride and sulphate dominated salinity, respectively, in wheat plant at boot stage. Similarly, in wheat straw at maturity it decreased from 54.83 to 34.75 μg pot-1 (36.6%) and 61.89 to 43.81 μg pot-1 (29.2%) in chloride and sulphate dominated salinity, respectively. The decrease was prominent in case of Cu, Fe and Mn also across all the salinity levels. The mean ECe, water soluble Na+, Ca+, Mg2+, Cl- and SO4 -2 increased with increase in the salinity level from 0 to 12 dS m-1 across all the Zn levels and these increasing concentrations in soil affect the wheat crop. Availability of DTPA extractable Zn, Cu, Fe and Mn was decreased as the salinity levels increased from 0 to 12 dS m-1 and this affect can be reduced by increasing levels of Zn from 0 to 15 ppm. Therefore, Zn mitigates the effect of salinity.ThesisItem Open Access Effects of cooling rate alterations in critical temperature range and supplementation of anti apoptotic proteins on cryosurvival of Buffalo bull sperm(Guru Angad Dev Veterinary and Animal Sciences University, Ludhiana, 2015) Sharma, Manoj Kumar; Kumar, AjeetPresent study was conducted to standardize the freezing protocol for cryopreservation of buffalo bull semen by applying different cooling rates in critical temperature range and asses the post thaw semen quality by using: a) CASA based motion traits b) Hypo - osmotic swelling test (HOST) c) percent viability test and d) percent sperm abnormalities. Semen was frozen by using nine different programmed freezing protocols including control freezing protocol having nine different cooling rates between 4 °C to -15 °C temperature range and 1 traditional vapour freezing protocol. Data was analyzed to find the best cooling rate between 4 °C to -15 °C temperature range. Similarly seven different programmed freezing protocols having 7 different cooling rates including control freezing protocol were used in -15 °C to -60 °C temperature range, but cooling rate in 4 °C to -15 °C temperature range was kept constant with best cooling rate that was obtained in 4 °C to -15 °C temperature range. From -60 to -140 °C temperature range, cooling rates -50 °C/min was same for each protocol except vapour freezing. The % HOST reactive sperm was significantly (P < 0.05) higher (30.60 ± 3.69) in the protocol with 30 °C/min in 4 to - 15 °C as compared to other protocols in this temperature range, however there was no significant (P > 0.05) difference in the % individual motility, progressive motility and various sperm kinetic parameters (VAP, VSL, VCL, ALH, BCF, STR and LIN), sperm size viability. Total sperm abnormality significantly lower (24.43 ± 2.33) in protocol with 30 °C/min in 4 to - 15 °C as compared to and vapour freezing (37.03 ± 2.8). The percent total motility (39.9 ± 3.3) in protocol with 50 °C/min in -15 to -60 °C temperature range was significantly higher than protocol with 20 °C/min (25.10 ± 3.35) within same temperature range and also percent progressive forward motility (34.2 ± 3.2) former protocol was significantly higher than later protocol (19.80 ± 3.24). Percent HOS reactive spermatozoa in protocol with 50 °C/min (25.0 ± 1.9) in -15 to -60 °C temperature range was different significantly (P < 0.05) higher than other protocols except protocol with 40 °C/min within same temperature range. Buffalo bull, semen freezing curve will be showing 30 °C/min cooling rate from 4 to -15 °C temperature range, 40 or 50 °C/min from -15 to -60 °C temperature range and 50 °C/min from -60 to -140 °C temperature range. Another way to improve the post thaw semen quality was supplementation of semen extender with caspase inhibitors (Z-DEVD-FMK, Z-LEHD-FMK and Z-IETD-FMK @ 2, 4, 6, 10, 20 µM) and Bcl-2 proteins (@ 5, 10, 15 µM). We found that supplementation of Z-DEVD-FMK and Z- LEHD-FMK to the semen minimize the apoptotic like changes that developed during cryopreservation in a dose dependent manner by maintaining mitochondrial membrane potential and prevent externalization of phosphatidylserine by keeping low phospholipase (PLA) A1 and A2 activity. Z- LEHD-FMK @ 2 µM resulted in significantly (P < 0.05) higher % individual motility as compared to other supplementation doses. Z-DEVD-FMK and Z-IETD-FMK to the semen extender did not enhance % individual motility @ all supplementation doses. We found that Bcl-2 protein supplementation @ 5 µM dose improved post thaw semen quality indicated by increase in the % sperms with low PLA activity (non apoptotic sperms) as compare to controlThesisItem Open Access Exchange equilibria of zinc and nickel in soils varying in texture, organic matter and CaCO3(College of Agriculture Chaudhary Charan Singh Haryana Agricultural University Hisar, 2000) Mann, Harmandeep Singh; Sharma, Manoj KumarThesisItem Open Access Exchange Equilibria of Zn and Cd in Soils in Relation to FYM and City Sewage Application(College of Basic Sciences and Humanities Chaudhary Charan Singh Haryana Agricultural University Hisar, 1988) Sharma, Manoj Kumar; Mundra, M. CThesisItem Open Access Freezing time estimation of peas by experimental and numerical methods(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2016-07) Sharma, Manoj Kumar; Pratihar, A.K.Freezing temperature-time variation of peas has been studied both by numerical as well as experimental methods in the present work. Various thermo-physical properties of peas, viz. density, moisture content and specific heat were experimentally determined. Further, effect of different parameters, viz. cooling air temperature, cooling air velocity and initial temperature, on freezing times has also been studied. Numerical models were developed for two cases; (a) freezing at constant temperature and (b) freezing with successive depression in freezing point. Crank Nicolson method was used for the formulation of mathematical models and is solved using MATLAB. The numerical models have been duly validated. Numerical models predict the experimental data with a minimum and maximum error of 0.4% and 8.1% respectively. An experimental setup was also designed and fabricated for determination of freezing time. One hundred twenty six samples of peas were frozen under different operating conditions and time-temperature behaviour of every sample was recorded using data logger. Freezing time calculated by numerical model agrees very well with experimental data. Based on the experimental results, an empirical relation of freezing time as a function of cooling air temperature, cooling air velocity and initial temperature, was developed. The empirical relation predicts the experimental data with a minimum and maximum error of 0.43% and 7.2% respectively which shows that Freezing times predicted by empirical relation are in good agreement with experimental data.ThesisItem Open Access Impact of brackish water on chickpea (Cicer arietinum L.) cultivars(CCSHAU, 2019) Sonia Rani; Sharma, Manoj KumarThe present study was carried out with the two chickpea (Cicer aritinum L.) cultivars viz. HC- 3 and CSG-8962 with differ in their sensitivity to tolerance in the screen house, in which two experiments were conducted. In first experiment, the treatment consisted of two types (Cl- and SO4 2- dominated) with the three levels 2, 4 and 6 dS m-1 of salinity. In the second experiment, the treatment consisted of three RSC level (0, 2.5 and 5.0 me L-1) with fixed ECiw 2.0 dS m-1 and constant SAR 20 (mmol L-1)1/2 along with the control or untreated. Both the experiments were replicated thrice in a factorial completely randomized design and the desired types of salinity and RSC levels were created using salts of the Na+, Ca+ and Mg2+. Germination of chickpea decreased and delayed with increased level of chloride and sulphate dominated salinity from control to 6 dS m-1 and in RSC dominated irrigation water from control to 5.0 me L-1. With the increasing level of salinity and RSC there was a reduction in the biomass, grain and straw yield of chickpea cultivars. However, the magnitude of adverse effect increased with increased the salt stress. The water potential (Ψw) of leaves and osmotic potential (Ψs) of leaves and roots became more negative with increasing in salt stress through salinity and RSC. HC-3 showed significantly higher accumulation in proline, glycine betaine and TSC contents than CSG-8962 at higher levels of salinity and RSC of 6 dS m-1 and 5.0 me L-1, respectively, as compared to control. Quantum yield, total chlorophyll and anthocyanin content was more decrease in CSG-8962 than HC-3 with increasing levels from control to 6.0 dS m-1 in both types of salinity and and 5.0 me L-1 in RSC dominated soils. Accumulation of MDA content, higher rate of lipid peroxidation was also higher in CSG-8962 than HC-3 at higher level of salt stress. The leakage of the ions which is measured as relative stress injury increased with increasing levels of both type of salinity and RSC. Relative stress injury was found to be more in CSG-8962 as compared to HC-3 in the leaves and roots at higher level of salt stress through salinity and RSC. pH of soil increased with increased in salinity and RSC levels. ECe increased with increasing level of salinity and decreased with increasing level of RSC. Na+, Ca2++Mg2+, Cl-, SO4 2- in shoots and roots markedly increased with increased levels of chloride and sulphate dominated salinity and RSC on the irrigation water applied to soil, K+ content decreased under salinity and RSC dominated soils. This experiment showed that there was no out flow of the effluent occurred in case of the soil column irrigated with high bicarbonate dominated water due to the reduction in the hydraulic conductivity. By increase in the level of irrigation (dominated in chloride, sulphate and bicarbonates), large amount of water was needed for the leaching of the salts from the root zone, so as reach to the desired level of salt concentration of the effluents.ThesisItem Open Access Impact of long-term zero tillage induced changes in soil properties on persistence of pendimethalin in different cropping systems(CCSHAU,HiSAR, 2020-05) Babal, Bhawna; Sharma, Manoj KumarA field study on the ‘Impact of long-term zero tillage induced changes in soil properties on persistence of pendimethalin in different cropping systems’ was carried out during kharif 2019 in an ongoing experiment on conservation agriculture (CA) laid out in 2006 at Soil Research Farm, CCS HAU, Hisar, on an alluvial sandy loam soil. The experiment was laid out in split-plot design having three tillage practices i.e. zero tillage in both kharif and rabi seasons (ZT-ZT), conventional in kharif and zero tillage in rabi (CT-ZT) and conventional tillage in both the seasons (CT-CT), and two cropping systems i.e. mungbean-wheat (M-W) and sorghum-wheat (S-W). Pendimethalin available as Penda (30 EC) was applied @ 1.0 kg a.i. ha-1 immediately after sowing. Soil samples collected from different depths and times were analysed for soil properties and herbicide residues. Residues were extracted using column chromatography and analyzed on GLC. The results revealed that the ZT-ZT improved soil properties over CT-ZT and CT-CT practices, subsequently led to increase in half-life by 1.17 days over CT-CT in surface 5 cm soil. The ZT-ZT led to leaching of the herbicide beyond 15 cm upon 78.3 mm of rainfall after 5-6 days of its application. The cropping systems did not significantly influence the persistence. No residues were observed in grain of mungbean and straw of sorghum. A reversible change in the equilibrium of the population of soil microorganisms took place under different treatments, largely within 15 days of herbicide application. These microorganisms were significantly higher under ZT-ZT compared to other practices. Bacteria were sensitive to pendimethalin while fungi and actinomycetes showed moderate toxicity to the herbicide but actinomycetes grew exceptionally faster than bacteria and fungi during the season. Azotobacter and PSB experienced a moderate initial stimulation but higher simulation of Azotobacter under CT-CT accentuated them for efficient in utilizing easily available pendimethalin while steady growth of PSB towards harvest demonstrated their capability to utilize molecules that are adsorbed strongly to soil colloids. Herbicide under the two cropping systems had no significant influence on bacteria, actinomycetes and fungi but the population largely remained numerically higher under S-W during the season. Azotobacter and PSB, however, increased significantly at harvest in surface 5 cm and throughout the season in 5-15 cm soil depth under M-W. The study illustrated that the induced changes in soil properties under CA, though enhanced persistence but increased leaching emphasizing on potential risk of the herbicide for groundwater contamination, particulary, under shallow water-table conditions when applied during rainy season in light textured soils of semi-arid regions. The information concerning the toxic effect of the herbicide on agriculturally important soil microorganisms under long-term CA as a whole generated in present investigation has a greater significance under field conditions as the literature available is largely based either on laboratory or short-term field experiments.ThesisItem Open Access Long term effect of FYM and nitrogen application on N, P, K fractions and distribution pattern of available nutrients in soil under pearl millet-wheat cropping system(CCSHAU, 2019) Deepika; Sharma, Manoj KumarAn ongoing long-term field experiment on Integrated nutrient management (FYM and fertilizer N) under Pearl millet wheat cropping sequences, established in October 1967, at research farm, department of soil science, CCS HAU, Hisar, India was selected to study “Long term effect of FYM and nitrogen application on N, P, K fractions and distribution pattern of available nutrients in soil under pearl millet-wheat cropping system”. The experimental treatment consisted of three level of FYM (15, 30 and 45 Mg/ha) till 2007-08 and 5, 10 and 15 ton per hectare from 2008-09 onwards. There mode of application: every Kharif crop (summer season), in every Rabi crop (winter season) and in both (Kharif and Rabi) the crop. An absolute control without application of FYM in any of the seasons was maintained as a control. These 10 treatments( 3 FYM level x 3 modes of application+ I FYM control) were allocated in the main plots and each main plot was subdivided into three subplots receiving fertilizer N at 0, 60 and 120 kg N/ hectare in each season through urea using split plot design. All the treatments were replicated three times, each subplot measuring 10 x 5 m FYM was incorporated in top 15-20 cm layers 3 to 4 weeks before sowing the crops. Significant increase in electrical conductivity, Soil organic carbon, Dissolved organic carbon, Calcium and Magnesium, all macro nutrients and micronutrients (Zn, Mn, Cu, Fe), Total nitrogen and Nitrogen fraction, Total Phosphorus and Phosphorus fractions and Potassium and Potassium fractions was observed when FYM applied at 15 Mg/ha, followed by 10 and 5 Mg/ha, however decrease trend observed for pH of soil at all the depth. The changes in all organic nitrogen fractions (Acid insoluble N, Total hydrolysable N, hydrolysable NH3-N, amino sugar N, amino acid N, hydrolysable unknown N) were more dynamic in various treatment combination consisting of modes and levels of FYM and N fertilizer. Increase in EC, SOC, DOC, macro(N, P, S, Ca, Mg) and micronutrient of soil, Total N and its fractions, Total P and its fractions and was noticed when increase in amount of N application at all the modes and level of application from control to 120 kg/ha, but pH, Total K and its fractions shows reverse trend. Continuous application of organic manure (FYM) along with N fertilizer for 50 years led to resulted in increase in content of protein, chlorophyll content, Grain and straw yield , Nutrient concentration and uptake (macro and micro nutrients),Leaf area index, Crop growth rate, Relative growth rate, C in seeds of wheat crop.ThesisItem Open Access Long-term effects of organic manures and fertilizers application on soil phosphorus dynamics and wheat yield(CCSHAU, Hisar, 2022-11) Rakesh Kumar; Sharma, Manoj KumarAn on-going long-term field experiment started since 1995 (Rabi) under pearl millet-wheat cropping system at research farm of department of Soil Science, CCS HAU was selected to study the effects of various combinations of organic manures and fertilizers on phosphorus dynamics and wheat yield. The plant and soil samples were collected after 24 cycles of pearl millet-wheat cropping system after the harvest of wheat crop. Irrespective of the treatments, soil EC, SOC, N, P and K. were higher in surface soils as compared to lower depth soils. Continuous addition of organic manures alone or in combination with chemical fertilizers for 24 years decreased the soil pH as compared to initial value. A significantly increase in SOC, available N, P and K content was observed with integrated nutrient management practices as compared to organic manures or chemical fertilizers applied alone. The highest SOC content (1.18 and 0.70 in 0-15 and 15-30 cm soil depths, respectively) was observed in plot receiving FYM along with recommended dose of N and half of recommended dose of P fertilizer. Application of organic manures alone or in combination with recommended dose of N and half of recommended dose of P fertilizer resulted in decrease in N as compared to initial status of N at the start of experiment. The amount of P adsorption by different treatments followed the order N150P60 > poultry manure5 > pressmud7.5 > FYM15 >Poultry manure5N150P30 > Pressmud7.5N150P30 > FYM15N150P30. The trend of adsorption suggests that the use of organic manures along with fertilizer reduces P adsorption. The soil that adsorbed a large amount of applied P during adsorption study, tended to desorbs a lower amount of adsorbed P in desorption study and vise-versa. A rise in P was observed up to 30th day of incubation and then a decrease was noticed. Combined application of organic manures along with recommended dose of N and half of recommended dose of P fertilizer i.e. FYM15N150P30 and Pressmud7.5N150P30 recorded 18 and 21%, respectively higher grain yield as compared to recommended dose of NP fertilizers. The higher N, P and K content in wheat grain and straw was observed with the conjunctive use of organic manures along with recommended dose of N and half of recommended dose of P fertilizer. The integrated use of organic manures and fertilizers resulted in higher productivity, improved soil health.ThesisItem Open Access Studies On Transformation Of Micronutrients In Dominant Soil Orders Of Rajasthan(Maharana Pratap University of Agriculture and Technology ;Udaipur, 2002) Sharma, Manoj Kumar; Swami, B.N.ThesisItem Open Access A Study of market Acceptance, Potential and Preference for Hybrid Rice Seeds in Navsari And Valsad District of Gujarat(ASPEE of Agribusiness Management Navsari Agricultural University, 2012-06) Sharma, Manoj Kumar; Dhaduk, B.
