    Nutrient management of mustard varieties under saline water irrigation
    (CCSHAU, 2019) Priyanka; Ram Prakash
    Several 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.

    Self-esteem, achievement motivation and academic performance of high school children
    (CCSHAU, 2018) Priyanka; Balda, Shanti
    Self-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.

    Assessment of nutritional status of anaemic pregnant women of Hisar and Fatehabad districts of Haryana
    (CCSHAU, 2017) Priyanka; Boora, Pinky
    Eight hundred fifty pregnant women were selected from the 6 villages (Bhojraj, Dahima, Kaimiri, Mirkan, Gunjar, Ladwa) of Hisar-I block and 6 villages (Chodhrywas, Kalwas, Balasmand, Bheria, Aryanagar, Dobhi) of Hisar-II block of Hisar district and 6 villages (Badopal, Chinder, Bhodia Khera, Kumharia, Dhanger, Kharakheri) of Fatehabad block and 6 villages (Kirdhan, Pilimandori, Bhattu Kalan, Bhattu Mandi, Thulan, Dhand) of Bhattu block of Fatehabad district of Haryana. Out of 850 pregnant women, screened for Hb level, 602 (70.82%) were found to be anaemic (<11g/100ml) 46.70 per cent from Hisar district and 53.29 per cent from Fatehabad district. Thus overall 70 per cent of the pregnant women were anaemic in four blocks of Hisar and Fatehabad districts. Results indicated significantly high prevalence of anaemia among pregnant women in rural areas of Haryana. Nutritional status of anaemic pregnant women was assessed using dietary survey (24h recall method), anthropometric measurements and clinical assessment which revealed that the food and nutrient intake was lower than the SDI and RDA among rural areas. Intake of cereals, pulses, fats and edible oils, green leafy vegetables, roots and tubers, other vegetables and fruits by respondents belonging to nuclear families was higher than those of respondents of joint families. The intake of cereals, milk and milk products was found to be increased with increased income of the family. Education of respondent influences the intake of food groups. Intake of energy and protein was higher by respondents of nuclear families. Intake of energy, fat, calcium, iron, β-carotene, thiamine, niacin, folic acid and vitamin B12 was found to be higher in the respondents whose average family income was Rs 18,000-27.000/month as the intake of pulses and milk products was higher by the respondents of nuclear families as compared to the respondents of joint families. The intake of food groups was higher among the respondents whose husband was engaged in service. Mean daily food and nutrient intake by respondents of Hisar district were found significantly (p≤0.01) lower as compared to Fatehabad district. Out of 300 hundred respondents, 200 respondents, 100 from Hisar and 100 from Fatehabad district were selected for imparting nutrition education and to assess food and nutrient intake. Nutrition education was imparted for a period of three months and gain in nutritional knowledge was assesed. The foods and nutrients intake of the respondents was increased significantly (p≤0.01) after imparting nutrition education. There is an urgent need to impart nutrition education to the pregnant mothers so that they can take balanced diet and improve health and nutritional status of future generation of country.

    Assessment of multiple Intelligence of school going boys
    (CCSHAU, 2017) Priyanka; Chhikara, Sudha
    A 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.

    Identification of molecular markers for Karnal bunt resistance in wheat (Triticum aestivum L. em. Thell)
    (CCSHAU, 2014) Priyanka; Redhu, A.S.
    Present study was carried out to screen 104 recombinant inbred lines (RILs) of cross H 567.71 (resistant) x WH 542 (susceptible) for Karnal bunt resistance and to identify SRAP and RGAP markers associated with Karnal bunt resistance in wheat. There was significant variation among all the recombinant inbred lines for percentage and coefficient of infection to Karnal bunt. Most of the RILs (68) and (71) showed up to 5% infection during the year 2011-12 and 2012-13 and thus were resistant. The percentage of infected grains or percent infection (PI) in the susceptible RILs was up to 37.14 % in the year 2011-12 and up to 31.57 % in the year 2012-13 respectively, whereas, range of coefficient of infection (CI) in the RILs was 0 to 14.21 % in the year 2011-12 and 0 to 13.81 % in the year 2012-13, respectively. Significant variations were also observed for different morphological traits such as, plant height (cm), days to flowering, days to maturity, number of tillers/meter length, spike length (cm), no. of grains/spike, 1000 grain weight, grain yield/meter length (g) and biological yield (g). A total of 80 SRAP and 121 RGAP primer combinations were used to screen parental genotypes. In SRAP, a total of 287 unambiguous bands were amplified by the 20 SRAP of 80 SRAP primer combinations, of which 123 bands were polymorphic (42.85 %). The cluster analysis led to distribution of parents and their RILs in to two major groups at the similarity coefficient value of 0.55. Major cluster I, included resistant parent H 567.71 with resistant lines and major cluster II had susceptible parent WH 542 and susceptible lines, these two groups further subdivided at similarity coefficient of 0.67 into four different clusters. In RGAP, a total of 89 unambiguous bands were amplified by the 9 of 121 RGAP primer combinations, of which 46 bands were polymorphic (51.68 %). Genetic similarity by RGAP analysis showed that parental genotypes were quite distinct from each other. The cluster analysis led to distribution of parents and their RILs in to two groups at the similarity coefficient value of 0.42. Major cluster I, included resistant parent H 567.71 with resistant lines and major cluster II had susceptible parent WH 542 and susceptible lines. These two groups further subdivided into six different clusters at similarity coefficient of 0.56. By single marker analysis, RGAP 7, RGAP 8 and RGAP 9 were directly linked with resistance genes which provide resistance against Karnal bunt. Hence, selection of Karnal bunt resistant genotypes on the basis of these three markers in early generations can be done through marker assisted selection and could be useful in future development of Karnal bunt resistant varieties.

    Isolation and evaluation of nodule endophytes for growth promotion in chickpea (Cicer arietinum L.)
    (CCSHAU, 2016) Priyanka; Leela Wati
    Legumes are among the World's most important crops. The family Fabaceae comprises of around 20,000 plant species in 650 different genera. Chickpea belongs to the Papilionoideae family, order Leguminosae and botanically recognized as Cicer arietinum L. As a leguminous plant, chickpea could be nodulated by rhizobial and nonrhizobial endophytic bacteria that exert several beneficial effects on host plant such as stimulation of plant growth, nitrogen fixation and induction of resistance to plant pathogen. The use of endophytes offers an attractive way to replace chemical fertilizers, pesticides and supplements. In the present investigation, a total of 107 bacterial endophytes including mesorhizobial and nonrhizobial, were isolated from healthy pink nodules of chickpea plants, collected from different districts of Haryana. Out of 107 endophytic isolates, 75% showed indole acetic acid production activity, which ranged between 0.33-19.56 µg/ml. P-solubilization activity of endophytic isolates on solid as well as liquid medium was restricted to 52% of the isolates only and their Psolubilization index (P-SI) varied from 1.0 to 3.4. Siderophore production was observed in 14% of the endophytic isolates. Twenty one of mesorhizobial endophytes out of 24, showed positive nodulation of chickpea variety HC5 under sterilized conditions. Six endophytic isolates including five nonrhizobial BE13, RE6, HE5, HE7 and ME3 and one mesorhizobial HM2, showing all the three plant growth promoting traits were further assessed for more plant growth promoting traits viz. A CC utilization, salt tolerance and potassium solubilisation. All the six endophytes showed ACC utilization activity and salt tolerance upto 4 % concentration while only endophyte, RE-6 showed potassium solubilisation activity.Three promising endophytes including two nonrhizobial RE6 and BE13 and one mesorhizobial HM2 were selected for evaluation of nodulation efficiency and plant growth parameters of chickpea under pot house conditions. Nodulation efficiency of endophyte RE-6 when coinoculated with rhizobial endophytes HM2 and phosphate solubiliser P-36 was better on the basis of nodule number, fresh wt. and dry wt. at 75 days of sowing. More seed weight, shoot dry weight and N and P content were also observed in coinoculation treatment of RE6 with HM2 and P36 while the isolate BE-13 when coinoculated with standard Rhizobium MSD-26 and phosphate solubiliser P-36 showed higher root dry weight at 75 days as well as at harvesting. Sequence analysis of 16S rDNA of endophyte BE13 showed 98% similarity with Bacillus boroniphillus and isolate RE-6 showed 99% similarity with Pseudomonas fluorescence.
