    Studies on insect pest complex in pulses, biology and management of spotted pod borer, Maruca vitrata (Fabricius) in green gram, Vigna radiata (L. Wilczek)
    (CCSHAU Hisar, 2022-07) Sonu Kumari; Balbir Singh
    The current studies entitled “Studies on insect pest complex in pulses, biology and management of spotted pod borer, Maruca vitrata(Fabricius) in green gram, Vigna radiata (L. Wilczek)” was carried out at CCSHAU Regional Research Station, Bawal and oilseed section, Deparment of Genetics and Plant Breeding during Kharif 2020 and 2021. Survey revealed that the population of leafhopper (6.96 leafhopper/plant), hairy caterpillar (0.85 larvae/plant), aphid (12.04 aphid/plant), whitefly (7.71 whitefly/plant), spotted pod borer (2.75 larvae/plant), blister beetle (13.24 adults/plant) and tur pod bug (6.63 bugs/plant) was more abundant in Gurugram district as compared to Mahendragarh and Rewari. The seasonal incidence revealed that the larval population of spotted pod borer increased significantly with maximum temperature (r=0.956 and 0.761) and showed significant negative correlation with rainfall (r=-0.823 and -0.911) during Kharif 2020 and 2021, respectively. The biology of spotted pod borer, M. vitrata showed that total developmental period (egg to adult) was 34.35±1.62 days. The fecundity of female moth was on an average 47±5.48 eggs/female. The treatment azadirachtin (0.03%) was found most effective protectants resulted in reduction larval population (4.32 larvae /m2), per cent pod damage (12.94%) and highest grain yield (13.01 q/ha) as well as per cent increase yield over control (35.69%) followed by neem oil (20 ml/l) and neem seed kernel extract 5 per cent (50 ml/l). The trichome density on leaves and pods and pod breadth was responsible for the resistance to spotted pod borer. Whereas, pod size, number of grains per pod and pod wall thickness were associated with the susceptibility to M. vitrata. Expression of resistance to spotted pod borer infestation was associated with higher amount of phenol content, low amount of soluble sugar and crude protein in pods as well as grains of pulses crop.

    Developmental Status of Urban Preschoolers in Relation to Food Intake
    (CCSHAU, Hisar, 2021-01) Sonu Kumari; Duhan, Krishna
    The present study was conducted in Hisar district of Haryana state to assess the developmental status and food intake of urban pre-schoolers and to determine the impact of food intake and sociopersonal variables on developmental status. Hundred preschool children of 3-6 years age (55 boys and 45 girls) from four preschools i.e. preschool laboratory I.C. College of Home Science, Little angel play school, Small wonder public school and Kids care play school of Hisar district were selected randomly. Developmental status of preschool children was assessed by using checklist of various developments designed by UNICEF India and Centre for Early Childhood Education and Development (CECED) Ambedkar University, Delhi. Nutritional status of children was assessed in terms of dietary assessment, 24 hour recall method was used and anthropometric measurement (height and weight) were taken. Results indicated that majority of respondents belonged to general caste (51.00%) category followed by backward (30.00%) and scheduled caste (19.00%). Majority of respondents (48.00%) belonged to small size families. Majority of respondent’s mothers and fathers were educated up to graduate/PG. Majority of respondent’s fathers (54.00%) were engaged in service. More percentage of the respondents (49.00%) had monthly income above 3 lacs. Mean daily intake of cereals, pulses, milk and milk products, roots and tubers, green leafy vegetables and fruits were found significantly lower than their respective RDIs. Mean daily intake of energy, protein, fat, calcium and iron were also found significantly lower than their respective RDAs. Gender wise comparison showed that mean daily intake of foods and nutrients were found higher in boys than girls. Socio-economic variables such as family type, family income, mother’s education and father’s occupation had significant effect on food and nutrient intakes of school children. Mean height and weight of boys and girls were found significantly lower than reference values. Boys had higher mean values of all anthropometric measurements than girls. As per weight for age, 51.00 percent of urban preschool children were found in grade-1 malnutrition and 20 per cent in Grade-II malnutrition and no one was found in Grade-III malnutrition. Results revealed a significant association of developmental status with mother’s education, father’s education, father’s occupation, gender, family size, family type and family income. Results revealed that dietary intake of preschool children were positively and significantly associated with developmental status of preschool children. Therefore, there is an urgent need to educate mothers of urban preschool children about the importance of balanced diet and promote the consumption of micronutrients rich food stuffs in daily diet of the school children to improve their nutritionally status.
