    An exploratory study on stress level among adolescents and coping mechanism
    (CCSHAU, 2019) Monika; Mehta, Manju
    Adolescence period begin between ages 13 and 19 years and it is the transitional phase from childhood to adulthood. Stress has become a predictable word in the fast turning technical word. Stress has been experienced by almost everyone in all segment of life. The stress was ominous in earlier period now it becomes a normal part of life. The objectives of study were to assess the level of stress among adolescents, to delineate the factors causing stress among the adolescents, to identify the coping mechanism adopted by the adolescents. The present study was conducted in Hisar city of Haryana state. Two government senior secondary schools and two private schools were randomly selected. The two government senior secondary schools were Government Senior Secondary School, Model Town and Government Senior Secondary School, Patel Nagar. The two private schools were New Yashoda Public School, Siddharth International School. 200 adolescents (25 girls and 25 boys) in the age group of 15 to 19 years were selected random from each school. Total sample comprised of 200 adolescents (100 girls and 100 boys). Level of stress was assessed by using the Student Stress Scale by Zaki Akthar (2011). Results revealed that in adolescent girls and boy's main reason of stress was way of living and academic factors. Girls were more stressed due to academic factors whereas cognitive stress was found more among boys. Adolescent's girls and boys experienced moderate level of stress due to stress causing factors. As per the student stress scale level of stress was below average in girls and moderate level in boys of government schools whereas in private school both girls and boys were having moderate level of stress. Adolescent boys experienced more stress as compared to girls. Confusion was the main stress symptoms among adolescents. Adolescents adopted the relaxation technique in the form of listening music and self distraction technique in the form of playing games, watching T.V.

    Persistence and leaching behaviour of premix formulation of flubendiamide and buprofezin in soil
    (CCSHAU, 2018) Monika; Duhan, Anil
    In Agrochemicals Residues Testing Laboratory, Department of Agronomy, Chaudhary Charan Singh Haryana Agricultural University a laboratory experiment was conducted to study the persistence behaviour and leaching potential of flubendiamide and buprofezin residues in sandy loam and clay loam soil. To study the persistence behaviour of flubendiamide and buprofezin at single and double dose, i.e., 210 and 420 g a.i./ha, was applied in soil taken in plastic pots. Soil samples were collected periodically on 0 (1h), 1, 3, 7, 10, 15, 30, 45 and 90 days after treatments. In leaching experiment, flubendiamide and buprofezin was applied at 50 (single dose) and 100 μg (double dose) in both soils packed in plexi glass columns. Residues of flubendiamide and buprofezin were estimated by HPLC coupled with Quadrupole Dalton Mass Detector (QDa) and GC-MS-tandem mass spectrometry equipped with capillary column. For both insecticides limit of detection and quantification were 0.001 and 0.005 μg/g, respectively. Dissipation followed a first order kinetics in case of both flubendiamide and buprofezin. Half-life of flubendiamide was found to be 25.1 and 26.6 days in clay loam soil and in case of sandy loam, 27.3 and 31.3 days at both the doses, respectively. For buprofezin, half-life was 12.4 and 12.6 days in clay loam and 19.1 and 20.2 days in sandy loam at both the doses, respectively. The residues were below detectable limit after 45 days in case of flubendiamide for both the treatments however buprofezin residues reached below detectable limit after 60 days. Leaching experiment was carried out in laboratory under continuous flow conditions. The residues of flubendiamide and buprofezin were retained up to soil depth of 30-35 cm but maximum retention was found upto 15 cm in flubendiammide and upto 20 cm in buprofezin. There were no fractions of flubendiamide and buprofezin residues in leachate indicating about poor leaching potential of both insecticides.

    Effect of cutting management and phosphorus fertilization on forage yield, quality and seed yield of multicut oat (Avena sativa L.)
    (CCSHAU, 2017) Monika; Sheoran, R.S.
    The field experiment entitled “Effect of cutting management and phosphorus fertilization on forage yield, quality and seed yield of multicut oat (Avena sativa L.)” was conducted during the rabi season of 2016-17 at the Forage Research Farm of Chaudhary Charan Singh Haryana Agricultural University, Hisar with the objective to study the effect of cutting management and phosphorus fertilization on forage yield, seed production, quality and economics of different treatments for oat. Treatment combinations comprised of eight cutting management treatments i.e. C1 (Seed to Seed), C2 (Fodder at 50% flowering), C3 (Fodder 60 DAS- Seed), C4 (Fodder 70 DAS- Seed), C5 (Fodder at 80 DAS- Seed), C6 (Fodder 60 DAS- Fodder at 50% flowering), C7 (Fodder at 70 DAS- Fodder at 50% flowering), C8 (Fodder 80 DAS- Fodder at 50% flowering) and four levels of phosphorus i.e. control, 20, 40 and 60 kg P2O5/ha. The experiment was laid out in split plot design and replicated thrice. The soil of the experimental field low in available nitrogen (161 kg N/ha, medium in available), phosphorus (12 kg/ha, medium in availibity), K (252 kg/ha, slightly alkaline in reaction having pH 7.8). The results indicated that the highest fodder and dry matter yield was obtained when only one cut of fodder was taken at 50% flowering stage and it was statistically at par for green fodder yield with treatment where first cut for fodder was taken at 80 DAS and second cut at 50% flowering stage. Harvesting of fodder at 80 DAS gave significantly higher forage yield and seed yield than the harvesting at 60 or 70 DAS. Contrary to this, the straw yield and biological yield were significantly higher in the treatment when the crop was raised purely for seed purpose. Under dual system, delay in first cut i.e. from 60 to 80 DAS resulted in a significant increase in fodder yield, seed yield, crude protein yield and net returns over the earlier cuttings. Every incremental dose of applied phosphorus resulted in a significant improvement in forage, seed and straw yield as well as the quality parameters and nutrient uptake over the lower doses. Harvesting of fodder at 50% flowering stage only gave the highest net returns and B: C ratio, whereas, under dual system, maximum net returns as well as B: C ratio was realized when first cut was taken at 80 DAS and then the crop was left for seed purpose. Application of 40 kg P2O5/ha also resulted in the higher forage and seed yield along with maximum net returns.

    Studies on development of instant rajmash and rice convenient mix
    (CCSHAU, 2017) Monika; Siddiqui, Saleem
    The present investigation ―Studies on development of instant rajmash and rice convenient mix‖ was conducted with the objectives to develop instant rajmash - rice convenient mix and to study its shelf life. The instant rajmash was prepared from var. Chitra and instant rice was prepared from var. Basmati. The instant spice m ix was also prepared. For instantization of rajmash and rice, grains were soaked, cooked, frozen and then to ~ 5% moisture level either by cabinet dryer (40-45oC) or freeze dryer. The instant products were packed in LDPE and metalized polypropylene pouches, stored for three months at room temperature and analysed at monthly intervals for various physical characteristics, nutritional quality and sensory attributes. It was observed that grain hardness, rehydration ratio, volume expansion ration, moisture content and total protein decreased, while total sugars, non enzymatic browning, peroxide value and free fatty acids increased in reconstituted rajmash-rice with increase in storage period of convenient rajmash-rice mix. However, the reconstituted rajmash-rice prepared from stored convenient rajmash-rice mix did not show any detectable microbial growth. The overall acceptability scores of reconstituted rajmash-rice mix were lower for cabinet dried than freeze dried reconstituted rajmash-rice mix. The freeze dried convenient mix packed in metalized polypropylene was better than polypropylene bags. The convenient mix prepared by freeze drying can be reconstituted to sumptuous rice-rajmash by soaking in hot water for 10 min, while for cabinet dried convenient mix it took 15 minutes. However, the acceptability of reconstituted rajmash-rice was highly acceptable even when prepared from three months stored rice-rajmash convenient mix. The cost of production was recorded approximately Rs 29 for per 250 g pack of cabinet dried instant rajmash-rice mix and approximately Rs 38 for per 250 g pack of freeze dried instant rajmash-rice mix.
