ThesisItem Open Access Impact of nutrient management practices on soil organic carbon fractions under cereal based cropping systems(CCSHAU, Hisar, 2023-07) Priyanka; Dhram PrakashAn on-going field experiment started in Kharif 2020 at Research Farm, Department of Soil Science, CCS HAU, Hisar (India) was selected for present study. The soil samples were collected after harvest of moong in the month of July, 2022. Irrespective of the nutrient management practices, soil organic carbon (SOC) fractions i.e. SOC (7.3 mg kg-1), hot water soluble C (HWSC: 209.25 mg kg-1), dissolved OC (DOC: 41.85 mg kg-1), total OC (TOC: 8.5 mg kg-1), microbial biomass C (MBC: 395.42 mg kg-1), MB nitrogen (MBN: 41.45 mg kg-1), available N, P, K and micronutrients were higher in soils under maize-potato-moong cropping system. Soil electrical conductivity (EC) and available S were higher in soils under pearl millet-wheat cropping system. Soil pH and less labile C were highest in soils under maize-potato cropping system. Plots under pearl millet-chickpea cropping system exhibited significantly higher very labile C, labile C and recalcitrant C content. The results showed that application of organic nutrient source (FYM) + residue retention (RR) relatively reduced soil pH (7.86) as compared to inorganic sources applied alone or in combination with RR and, a reverse trend was obtained for soil EC. Significantly higher soil EC (0.40 dSm-1), HWSC (254.16 mg kg-1), DOC (50.84 mg kg-1), SOC (7.5 mg kg-1), TOC (8.9 mg kg-1), MBC(448.91 mg kg-1) and available Fe (20.50 mg kg-1), Mn (9.70 mg kg-1), Cu (1.35 mg kg-1) and Zn (1.83 mg kg-1) were found under treatment received organic nutrient source + RR over the other nutrient management practices. Combined use of inorganic nutrient sources and RR showed higher availability of P (20.97 kg ha-1) and K(426.00 kg ha-1) followed by sole application of inorganic nutrient sources (available P: 19.96 and available K: 417.7 kg ha-1). Application of inorganic nutrient sources coupled with RR showed beneficial impacts on availability of N (173.25 kg ha-1) and MBN (46.70 mg kg-1) as compared to sole application of organic nutrient source. Application of organic or inorganic nutrient sources along with RR helped to improve soil physico-chemical and microbial properties. Inclusion of nitrogen fixing legume i.e. moong has enhanced the soil OC fractions and improved nutrient availability. Therefore, nutrient management practices and choice of crops under intensive cropping systems could lead to improve the soil health.ThesisItem Open Access Development and Evaluation of Value Added Products incorporating Khejri (Prosopis cineraria) Pod Powder(CCSHAU,HiSAR, 2021-07) Priyanka; Sindhu, Sangeeta CThe present investigation was carried out to study the nutrient composition of Prosopis cineraria pod powder, development of products using Prosopis pod powder, their sensory and nutritional evaluation and studying the shelf life of the developed products. Ripe pods of Prosopis cineraria were subjected to oven drying and made into powder. Prosopis pod powder was analyzed for physico-chemical properties and nutritional composition. Four products namely biscuits, cake, sev and laddoo were prepared by substituting control flour with Prosopis pod powder at 10, 20 and 30% level of incorporation. Developed products were subjected to sensory evaluation and most acceptable products were analyzed for nutritional composition. Most acceptable biscuits and sev were also subjected to shelf-life evaluation during one month of storage period. Data was statistically analysed using SPSS and OPSTAT software. The water absorption capacity, oil absorption capacity and swelling power of Prosopis pod powder were observed as 2.24, 1.47 and 4.2g/g, respectively. The sedimentation value of Prosopis pod powder was observed to be 10.23ml/g.Prosopis pod powder contained 3.83, 19.64, 2.75, 17.35, 5.22 and 55.04 per cent of moisture, crude protein, crude fat, crude fibre, ash and total carbohydrates, respectively. Soluble, insoluble and total dietary fibre in Prosopis pod powder were found to be 9.47, 17.91 and 27.38 per cent, respectively. Total soluble sugars, reducing sugars and strach of Prosopis pod powder were noticed as 28.94, 3.67 and 13.25 per cent, respectively. Antioxidant activity (DPPH) and phytic acid content of Prosopis pod powder were observed as 64.94 mgTE/100g and 71.49 mg/100g, respectively. Prosopis pod powder contained 351.9, 519.3, 95.67, 897.97, 24.53 and 2.19 mg/100g of total calcium, phosphorus, magnesium, potassium, iron and zinc, respectively. The HCL extractable contents of calcium, phosphorus, magnesium, potassium, iron and zinc in Prosopis pod powder were observed to be 104.47, 179.46, 28.83, 351.35, 6.37 and 2.19 mg/100g, respectively. It was found that potassium had significantly highest per cent extractability (39.13%) among all the minerals. The organoleptic scores showed that biscuits, sev and laddoo were found most acceptable at 10% level of incorporation of the pod powder while the incorporation level 20% was found to be most acceptable for cake. The value added products had significantly higher protein, crude fibre, mineral content and antioxidant activity than control. Shelf life study of most acceptable products (biscuits and sev) was done. Significant (p≤0.05) differences were observed between control and Prosopis pod powder supplemented products in terms of lipase activity, peroxide value and total plate count during one month of storage period. Shelf-life study indicated that products could be stored well and microbiologically safe throughout the storage period. From the present study it is concluded that all the Prosopis pod powder supplemented products were found to have better nutritive value and shelf life than their controls. Commercialization and promotion such functional food commodities helps to tackle malnutrition and hidden hunger among the population.ThesisItem Open Access Nutrient management of mustard varieties under saline water irrigation(CCSHAU, 2019) Priyanka; Ram PrakashSeveral studies have been conducted on different varieties of mustard under the effect of mineral fertilizers and saline irrigation conditions. The experiment on “Nutrient management of mustard varieties under saline water irrigation” was carried out in rabi season of 2017-18 at Research farm, Soil Science Department, CCS HAU, Hisar. The experiment was laid out in a split plot design with three replications, with four mustard varieties in main plots (Kranti, Giriraj, CS-54 and CS-58) and three fertilizer doses in sub-plots [RDF (N, P and K @60:20:20 kg ha -1), 125% and 150% RDF] with application of saline water for irrigation (7 dSm-1). The results showed that the plant parameters like plant height, primary and secondary branches per plant, number of siliqua and seeds per siliqua showed significant increase up to application of 150% RDF under saline water irrigation. 1000-seed weight reported non-significant increase with increased fertilizer doses and recorded maximum in variety CS-58 (5.90 g) at 150% RDF. Oil content decreased non-significantly from RDF to 150% RDF and reported maximum under variety CS-58 (40.17% at RDF). Among four mustard varieties CS-58 recorded maximum seed and straw yield (22.89 and 88.33 q ha-1) at 150% RDF followed by CS-54, Giriraj and Kranti. Nutrient content (N, P and K) in straw increased significantly up to 125% RDF and remained at par with 150% RDF being highest in variety CS-58 followed by variety CS-54, Giriraj and Kranti, respectively. Na+: K+ decreased non-significantly from RDF to 150% RDF and mean significantly higher ratio was recorded in variety Kranti (2.85). Soil properties like pH, ECe and organic carbon reported no significant changes with respect to different varieties and fertilizer doses. Available N, P, K and S of soil after crop harvest increased significantly up to the application of 150% RDF and observed maximum under variety Kranti. The cationic composition of soil extract was observed in order Na⁺> Mg²⁺ > Ca²⁺> K+ likewise the anionic composition of soil extract was observed in order Cl-> HCO3-> SO42-> CO32-, respectively. Therefore, variety CS-58 reported better results with the application of 150% RDF under saline water irrigation.ThesisItem Open Access Development of processing technology for instant mango shake powder(CCSHAU, 2018) Priyanka; RekhaThe present investigation ―Development of processing technology for instant mango shake powder‖ was conducted with the objectives to optimize processing technology for development of instant mango shake (IMS).

After blanching, the product was either freez dried, tray dried or microwave assisted tray dried. After drying, dried mango pulp was ground to powder, mixed with skim milk powder (SMP) and sugar in 32:26:42 ratio, packed in aluminum laminated and polypropylene pouches and stored for three months at room temperature. IMS1 (prepared from mango pulp, mixed with skim milk powder and freeze dried) and IMS2 (prepared from microwave assisted tray dried mango pulp) had moisture content (4.60 and 4.15%), crude protein (0.82 and 0.77%), crude fat (0.42 and 0.46%), crude fibre (0.93 and 0.89%), ash (1.47 and 1.45%), carbohydrates (96.27 and 96.42%), energy (393.93 and 393.93 Kcal), calcium (262.67 and 252.33 mg/100 g), ascorbic acid (5.75 and 5.01 mg/100 g), carotenoids (1.14 and 1.09 mg/100 g), total phenols (39.19 and 34.17 mg/100 g), bulk density (0.94 and 0.89 g/cm3)and dispersibility (86.87 and 82.93%) The most acceptable instant mango shake powder i.e., mango pulp mixed with skim milk powder and freeze dried had moisture (4.60%), protein (0.82%), fat (0.42%), crude fibre (0.93%), ash (1.47%), carbohydrates (96.27%), energy 392.90 Kcal and calcium (262.67 mg/100 g), ascorbic acid (5.75 mg/100 g), total Carotenoids (1.14 mg/100 g) and total phenols (39.19 mg/100 g) Moisture content, water activity, acidity, non enzymatic browning, total soluble solids, solubility index and microbial load increased while, pH and ascorbic acid of the all three instant mango shake powder variants decreased significantly during three month of storage. Cost of IMS powder ranged from `247.54 to 46.72/100 g. All the instant mango shake powder variants were found acceptable even after three months storage.ThesisItem Open Access Self-esteem, achievement motivation and academic performance of high school children(CCSHAU, 2018) Priyanka; Balda, ShantiSelf-esteem refers to person's beliefs about his or her worth and value. Self-esteem is important because it influences individual's decisions. Achievement motivation is described as the need for performing well or the motivated for success and evidence by persistence or effort in the facing the difficulties. Academic performance as well as achievement both is the outcomes of education and the extent from which a student, teacher and the institution has accomplished their educational goals. The present study examines the relationship between self-esteem, achievement motivation and academic performance of high school children. The study was conducted in Hisar city and rural area of Hisar district. Total sample constituted of 240 adolescents, 120 from rural area and 120 from urban area, representing both the sexes in equal number. Self-prepared interview schedule was used to collect information on personal and socio-economic variables. Self- Esteem Inventory (Prasad and Thakur, 1977) was used to assess self-esteem of children. Rao‟s Achievement Motivation Test (Rao, 1974) was used to assess achievement motivation of children. For academic performance, percentage of marks secured in previous three examinations was obtained from school records. The results revealed that maximum percentage of high school children belonged to moderate category of personally perceived and socially perceived self-esteem. Irrespective of area of residence and sex of children, self-esteem of majority of high school children was high followed by negative and balanced. Majority of children had moderate level of achievement motivation. Majority of children from both the areas belonged to above average category of academic performance. There existed significant positive correlations between self-esteem (personally perceived and socially perceived) and achievement motivation and academic performance of children. Children with balanced and high self-esteem had high achievement motivation and performed better in academics than those with negative self-esteem. Results further revealed that socio-economic status of family was strong predictor of self-esteem and achievement motivation of children.ThesisItem Open Access Assessment of multiple Intelligence of school going boys(CCSHAU, 2017) Priyanka; Chhikara, SudhaA person can be most successful in a profession when the same is according to his or her abilities and interest. The different domains and disciplines valued by different cultures exert a tremendous influence over how one's intelligences develop, and to what extent they are mobilized. Focus these days is on designing educational experiences for students that demonstrate and explore how they are smart in the synergistic environment of a community of learners. The present study was accompanied with the aim of assessing the multiple intelligence levels of school going boys and to study the cultural differences in the levels. For this, 200 boys in age group of 6-8 years from rural and urban areas of Fatehabad district of Haryana state were selected. The data were collected with the help of standardized Multiple Intelligence Tool and a questionnaire for human ecological factors by Dabas, R. 2000. The results of the investigation elucidated that majority of the respondents were found to be having average levels of intelligence for all the nine components of multiple intelligence. Significant differences were observed in the mean scores of boys from urban area for linguistic, logical-mathematical, intrapersonal, naturalistic and existential intelligences whereas in rest of the intelligences i.e. Musical, Bodily Kinesthetic, Spatial, Interpersonal, no significant variations across rural and urban setting emerged. The results explained that all the aspects of multiple intelligence were significantly associated with human ecological factors of the respondents.ThesisItem Open Access Effect of biopolymer treatments on biochemical changes in ber (Ziziphus mauritiana L.) fruit during storage(CCSHAU, 2016) Priyanka; Jain, VeenaDuring present investigations, ber fruits of variety Kaithali (shelf -life 4-5 days) at mature green stage were harvested and were analyzed for various physico-chemical and biochemical parameters during storage. PLW, TSS content and sugars (total and reducing) of ber fruits with increasing storage period while fruit firmness and tittratable acidity exhibited continuous decrease throughout storage. The oxidative stress which is indicated by H2O2 content, MDA content and LOX activity, increased significantly during storage while the activities of ROS scavenging enzymes viz. SOD, CAT, POX, PPO and GR were invariably low at the later stages during storage. ROS scavenging metabolite viz. ascorbic acid, total phenolics, total flavonoids and antioxidative activity increased upto 8 th DOS and thereafter decreased at 10 th days of storage. However β-carotene decreased continuously throughout storage period. Pretreatment of chitosan and CaCl2 delayed PLW, decreased TSS content and sugars content and retained fruit firmness and acidity significantly during storage. Fruits treated with CaCl2 (2%) and chitosan (1%) alone and in combination could help them to retain higher antioxidative activity and ROS scavenging metabolites and the combined treatment of 2% CaCl2 and 1% chitosan was the most effective in enhancing storage ability of fruits.ThesisItem Open Access Studies on chemical weed control in berseem (Trifolium alexandrinum L.)(CCSHAU, 2015) Priyanka; Sheoran, R.S.The present investigation entitled, “Studies on chemical weed control in berseem (Trifolium alexandrinum L.) was conducted at Research Farm of Department of Agronomy, Chaudhary Charan Singh Haryana Agricultural University, Hisar during winter (rabi) season of 2013-14 to find out suitable herbicides for productivity enhancement by suppression of associated weeds like Coronopus didymus L. along with other weed flora in berseem (Trifolium alexandrinum L.). Fifteen herbicide combinations namely butachlor at 1000 and 1500 g/ha, pendimethalin at 750 and 1000 g/ha as PRE, imazethapyr at 50, 75 and 100 g/ha as PPI, PRE and 3 WAS and oxadiargyl at 75 and 100 g/ha as PRE were tested along with unweeded control (weedy check). All herbicide combinations along with weedy check were tested in randomized block design replicated thrice in the plots measuring 5×4 m 2 . Among herbicides, imazethapyr at 100 g/ha at 3 WAS scaled down the population of the entire weed flora including their dry weight appreciably in comparison to other treatments, whereas, the effect of pendimethalin against dominant weeds was not to the desirable level when applied at 750 and 1000 g/ha as PRE and caused phyto-toxicity on berseem plants. The application of imazethapyr at 100 g/ha applied as post-emergence resulted in the increased yield attributes viz. plant height and number of tillers as compared to the remaining herbicidal treatments as well as the weedy check. Significantly higher green fodder yield (859.8 q/ha) and dry matter yield (117.0 q/ha) were obtained with the use of imazethapyr at 100 g/ha as post-emergence than the other treatments except the lower doses of imazethapyr i.e. 50 and 75 g/ha as post-emergence, where the differences were non-significant. However, the quality parameters viz. crude protein content (%) and IVDMD (%) were not significantly influenced by the various treatments. The crude protein yield (24.3 q/ha) and DDM yield (68.4 q/ha) was significantly improved with the application of imazethapyr at 100 g/ha at 3 WAS over other herbicidal treatments and weedy check. The highest net returns (Rs. 55971/ha) and B:C ratio (1.77) was realized with the post-emergence application of imazethapyr at 100 g/ha.
