ThesisItem Open Access Dissipation and decontamination studies of cyantraniliprole in cabbage and soil(CCSHAU, Hisar, 2020) Poonam Rani; SushilDissipation and decontamination studies of cyantraniliprole (Benevia 10.26% OD) in cabbage and soil was carried out following spray of cyantraniliprole at fruit setting stage on cabbage crop grown in plots of 5 x5 m size at recommended (60 g a.i. ha-1) and double of recommended dose (120 g a.i. ha-1) by Central Insecticide Board (CIB). Samples of cabbage were processed using modified QuEChERS method and analyzed using HPLC with retention time of 15.351 minutes. Recovery experiments were performed on cabbage heads and soil sample fortified @ 0.05, 0.50 and 1.00 mg kg-1 and the recoveries obtained were in the range of 86.11 – 89.54% and 85.60 – 88.05% respectively. Initial deposit of cyantraniliprole residue in cabbage heads was 0.449 mg kg-1 and 0.576 mg kg-1 for single (T1) and double (T2) dose respectively. These residues dissipated following first order degradation kinetics with half- life of 1.91 and 2.29 days respectively and reached below limit of quantification (LOQ i.e. 0.05 mg kg-1) on 7th and 10th day for single (T1) and double (T2) dose respectively. Level of residues in soil were < LOQ for both single (T1) and double dose (T2) on 0 day of spray. Washing followed by boiling was found most effective (100%) in dislodging residues of cyantraniliprole than washing with 5% NaCl solution and washing alone.ThesisItem Open Access Genetic and environmental Influences on the personality of preschool twins(CCSHAU, 2016) Poonam Rani; Dhanda, BimlaGenetic and environmental influences on personalitytraits of twins from five cultural of state Haryana were assessed. A sample of 200 pairs of twins in the age groups of 3-6 years were shorted out from already identified twins from five cultural zones. Personality traits were assessed with the helpof Five Factor Personality Questionnaire (Cathy, 2011). Regarding personal profile of the respondents, the results revealed that most of the twins were boys having one sibling and second ordinal position. Majority of the twins were living in joint family with large family size. With regard to parental education, highest percentage of twins were having their fathers educated above matriculation but were farmers. Where as mothers were educated upto middle school that was the reason they were homemakers. Result on the twins indicated that all the traits, namely, agreeableness, extraversion, neuroroticism, conscientiousness and openness were found to make significant difference in personality traits of twins on the basis of standard calculation. The heritability estimates shown a great role of genes in framing the overall personality of monozygotic twins.The associations of personality traits were significantly related to mother education, father education, and family income in Mewat zones. Preschool and home were also leading factors for personality differences in twins of all cultural zones.ThesisItem Open Access Genetic variability among the accessions of Sesbania species for morphological and biochemical markers(CCSHAU, 2005) Poonam Rani; SubhadraField experiment and isozymic analysis on 40 accessions of Sesbania were carried out with the objectives: (i) to estimate variability among accessions of Sesbania using various isozymes and morphological markers and (ii) to establish relationship among accessions using these parameters. The accessions were grown in randomized block design with three replications. The observations were recorded on 15 variables viz., plant height (at 20 and 60 days after sowing, and at maturity), green biomass, dry weight, number of root nodules, fresh weight of root nodules, leaf length, leaves per plant, leaflets per leaf, number of pods per plant , pod length, number of seeds per pod, 100-seed weight and seed yield per plant. Significant genotypic differences were observed for all the 15 morphological characters. Accession EC 493668 (T21) from Australia was identified for its direct exploitation as a cultivar. Seed yield showed positive correlation with number of pods, number of seeds per pod, pod length, leaf length and plant height at maturity. Weight of root nodules, number of pods and pod length showed high positive direct and indirect effects contribution towards their correlation with seed yield. Seed yield and its components showed medium to high heritability and genetic advance. UPGMA method with Euclidean distances based on agromorphological traits grouped accessions into seven clusters. Accessions T3 from cluster 1 and T24 from cluster 7 were recommended for hybridization programme for improvement of grain yield. Cluster 7 showed high inter cluster distance from clusters namely cluster 2, 3 and 4. The accessions were fingerprinted for 6 isozyme systems (acid phosphatase, amylase, catalase, glutamate dehydrogenase, peroxidase and malate dehydrogenase) and grouped the accessions into 11 clusters. Malate dehydrogenase and glutamate dehydrogenase exhibited maximum unique isozymic patterns i.e. 38 and 31, respectively followed by acid phosphatase, amylase, peroxidase and catalase. None of the enzyme system could alone distinguish all the accessions individually, however, a combination of any of the two enzyme systems may be used to distinguish all 40 accessions uniquely. Majority of accessions of S. rostrata were grouped together in one cluster in both agromorphological and isozymic data analysis. Both analyses indicated that geographical diversity is important but not the sole factor determining the genetic diversity.ThesisItem Open Access Isolation and characterization of rhizobia infecting fenugreek (Trigonella foenumgraecum L.)(CCSHAU, 2014) Poonam Rani; Kukreja, KamleshNutrient enrichment of soil by nitrogen fixing symbiotic bacteria present in legumes has been known for centuries. Fenugreek (Trigonella foenumgraecum L.) is one of the oldest herbs and annual plant in the family Fabaceae and is cultivated worldwide as a semi-arid crop. The largest producer of fenugreek in the world is India. Rajasthan produces the lion's share of India's production, accounting for over 80% of the nation's total fenugreek output. The most common nodule forming bacteria associated with fenugreek is the Gram negative, aerobic, nonsporulating, rod shaped bacterium, Rhizobium meliloti. In the present study, a total of 48 rhizobial isolates were obtained from nodule samples of fenugreek crop collected from farmer’s field of different districts (Sirsa, Hisar and Karnal) of Haryana state. Authenticity of rhizobia was done by plant infection test under sterilized conditions. All the rhizobial isolates formed nodules. On the basis of nodulation in sterilized cups, 31 fenugreek rhizobial isolates were characterized for IAA production, siderophore production, P- solubilization, temperature tolerance and bacteriocinogenicity. Out of 31 rhizobial isolates, 22 were IAA producers. IAA production ranged from 24.0 to 62.6 μg ml-1. Eleven were siderophore producers and their relative siderophore production ability varied from 1.25 to 1.87. Two rhizobial isolates were phosphate solubilizers and six rhizobial isolates produced bacteriocin. All the isolates were able to grow at 20, 25, 30oC; however few isolates showed diminished growth at 20oC. Plant growth promoting efficiency of these rhizobial isolates was assessed under pot house conditions and it was found that all the inoculated treatments were better than the uninoculated control. Nodule fresh weight, plant height, plant biomass and shoot nitrogen in plants increased significantly with the inoculation of FS12, FS15, FH36, FK23 and FK35 rhizobial isolates. Nodule fresh weight was recorded highest in FS12 (284 mg plant-1) followed by FS15 (282 mg plant-1) and FK36 (247 mg plant-1). Shoot dry weight was observed highest in FK35 (2.52 g plant-1) followed by FH36 (2.46 g plant-1) and FK23 (2.28 g plant-1). Shoot nitrogen content was observed highest in FK35 (84.19 mg plant-1) followed by FH36 (83.72 mg plant-1) and FK23 (75.20 mg plant-1). Based on characterization and pot house study, best fenugreek rhizobial isolates were FS12, FS15, FH36, FK23 and FK35.ThesisItem Open Access A study on soft skills of rural and urban preschoolers(CCSHAU, 2012) Poonam Rani; Dhanda, BimlaThe study was conducted in rural and urban areas of district Hisar. Two villages namely Balsmand and Kharia were taken as rural location and for urban the Hisar city was selected for collection of data.A total number of 200 children of age group of 3+,4+and 5+ years were taken ,out of which 100 children were found from urban and 100 from rural areas. Vineland Adaptive Behaviour Scale by Sparrow et al. (1935) was used to test the communicational and adaptive skills of children. Socio-economic status was assessed with self structured interview schedule. Home inventory by Bradley and Caldwell (1984) was used to judge the environmental conditions of children in their home. Social Attributes Checklist by Katz and McClellan (1997) was used to assess the social skills of children. Preschool Programme Evalution Sheet by Verna Hildrebrand (1981) was used to assess the preschool programme of children. Result revealed that children had increasing trend for soft and social skills with increase their age. Comparison over location shown that mean performance of children on soft and social skills were significantly different over the locations of boys and girls during the age 3+ to 5+ years. The further study revealed that aspects of home environment such as academic achievement was significantly associated with soft skills of urban children. Home environment such as modelling was significantly associated with social skills of urban children. Home environment such as learning stimulation and Physical stimulation were significantly associated with soft skills of rural children. Home environment such as language stimulation, physical stimulation, modeling and acceptance were significantly associated with social skills of rural children. The total home environment was also significantly associated with soft and social skills of rural children.
