ThesisItem Open Access A study on simulation techniques for queuing problems(CCSHAU, Hisar, 2022-12-07) Monika; Poonia, HemantAn important branch of Operations Research (OR) is Queuing Theory is also known as theory of waiting lines. The waiting time management plays a crucial role in today‟s competitive arena for optimizing the resources of an organization. The study on “A Study on Simulation Techniques for Queuing Problems” was planned to develop a Monte Carlo queuing model for assessment of queues and to analyze the waiting time in the warehouse. The arrival and service data for a season was gathered from a Warehouse in Tohana, Haryana. The model was used to analyze the queue characteristics like average arrival rate, average waiting time in queue, time spends in system and queue length or average number of conveyors in queue. It was found that the average number of arrivals was 2.6 conveyors/hr, number of customers waiting to be served in the queue were 14, the waiting time of the conveyors in the queue was 5.4 hrs and average time spends in the system was 5.8 hrs. The adequacy of developed model was tested using Little‟s law and it was found that the arrival rate obtained from the warehouse data is approximately same as the arrival rate achieved from the simulation.ThesisItem Open Access Effect of foliar application of chemicals on yield, quality and shelf life of ber (Zizyphus mauritiana lamk.) cv. Apple ber(CCSHAU, Hisar, 2023-05) Monika; Baloda, SatpalThe investigation entitled “Effect of foliar application of chemicals on yield, quality and shelf life of ber (Zizyphus mauritiana Lamk.)” was conducted at Experimental Orchard of Department of Horticulture, CCS Haryana Agricultural University, Hisar during the year 2022-23. Thirty nine uniform trees of ber cv. Apple ber were selected and foliar application of different concentrations of potassium sulphate, calcium nitrate and ethephon were sprayed in the last week of december and first week of january. The yield and quality parameters demonstrated a significant improvement. The fruits that were harvested from the trees treated with potassium sulphate @ 2.5% showed the greatest improvements in the yield parameters, including the number of fruits per tree, fruit length, fruit breadth, weight, and total yield per tree. Significantly improvement in quality parameters i.e. TSS, TSS/acid ratio, ascorbic acid and total sugar was observed in the fruits harvested from the trees treated with potassium sulphate @ 2.5 % which was statistically at par with potassium sulphate @ 2.0 %. while the minimum acidity was reported from the plants which were applied with potassium sulphate @ 2.5 % and potassium sulphate @ 2.0%. Pre-harvest application of different chemicals significantly influenced the quality parameters except specific gravity and stone weight. The nutrient content was also significantly affected with the application of various chemicals. The highest concentration of N and Ca content were found with the foliar spray of calcium nitrate @ 2.0 % while highest phosphorous and potassium content was found from the trees which were sprayed with ethephon @ 600 ppm and potassium sulphate @ 2.5% respectively. The application of potassium sulphate, calcium nitrate, and ethephon did not significantly affect the zinc content, but potassium sulphate @ 0.5% applied as a foliar spray resulted in the highest zinc content. The physiological loss in weight and spoilage percentage, which are indicators of shelf life, were also observed. Calcium nitrate @ 2.0%, caused the least physiological loss in weight, while ethephon, @ 600 ppm, caused the greatest physiological loss in weight and spoilage percentage in trees.ThesisItem Open Access Ameliorating effect of mepiquat chloride and gibberellic acid on Sorghum bicolor L. under salt stress(CCSHAU, Hisar, 2023-06) Monika; Sarita DeviThe present study entitled “Ameliorating effect of mepiquat chloride and gibberellic acid on Sorghum bicolor L. under salt stress.” was investigated in the screen house during the kharif season of 2022. Before sowing the pots were saturated to maintain desired levels of salt stress (control, 4, 6 and 8 dS m-1). On 16th August 2022, Sorghum bicolor L. seeds were sown in pots under controlled condition. After 50 days from sowing (DAS), exogenous application of mepiquat chloride (200 and 300 ppm) and gibberellic acid (200 and 400 ppm) under stressed and non-stressed plants of CSV 32F and CSV 35F genotypes. Sampling was done at 30 and 60 DAS. Increasing levels of salt stress led to a decrease in the growth parameters, while the application of mepiquat chloride and gibberellic acid resulted in enhanced plant growth. After the application of mepiquat chloride and gibberellic acid, the physiological characteristics were improved, counteracting the negative effects of salt stress. Parameters such as gaseous exchange, chlorophyll index and photochemical quantum yield exhibited a gradual decline from the control to 8 dS m-1 of salt stress in both genotypes. However, a higher percentage decrease was observed at the 8 dS m-1 salt stress level in CSV 35F over the respective control. For instance, there was a 20.29% decrease in RWC, a 42.36% decrease in assimilation rate, a 69.21% decrease in transpiration rate and a 79.35% decrease in stomatal conductance. The application of mepiquat chloride and gibberellic acid improving gas exchange and chlorophyll index, regardless of salt stress in both sorghum genotypes. On the other hand, the negative effects of salt stress, such as electrolyte leakage and ash content, increased with higher salt levels. However, the application of mepiquat chloride and gibberellic acid partially mitigated these adverse effects of salt stress. Specific activity of enzymes increases in salt stress as well as after application of mepiquat chloride and gibberellic acid. Salt stress enhanced the Na+ content but a decrease in K+ and Ca2+ content. Conversely, after applying mepiquat chloride and gibberellic acid, there was a reversal of this trend. Conclusively, sorghum genotype CSV 32F exhibited slightly better performance under salt stress and showed a more favorable response in mitigating salt stress when mepiquat chloride and gibberellic acid was applied exogenously.ThesisItem Open Access Teachers’ occupational aspiration and job satisfaction in relation to their emotional intelligence(CCSHAU, Hisar, 2021-09) Monika; Duhan, KrishnaThe present study was an effort to study Teacher’s Occupational Aspiration and Job Satisfaction in relation to their Emotional Intelligence. It was conducted in Hisar and Rewari district of Haryana state. A total combination of 160 teachers was selected from both the districts in which half of the sample population were belonged to Hisar district and other half were from Rewari district. To delineate personal and socio-economic variables, a self-constructed questionnaire was used. Teacher’s emotional intelligence level was assessed by Emotional intelligence test developed by Duhan (2005). Teacher’s occupational aspiration questionnaire by Nasrin and Anees (2013) was used to examine occupational aspiration of teachers and job satisfaction scale by Singh and Sharma (1990) was used to observe job satisfaction of teachers. The present study has come out with the results stated that medium level of emotional intelligence was reported in school teachers. Associations of emotional intelligence with personal and socio-economic factors of teachers showed significant associations with age, education, area of living, annual income, experience and type of school. The findings of the study revealed that teachers from both the districts were highly aspired regarding their profession and moderately satisfied with their job. Significant associations were found between occupational aspiration and job satisfaction with emotional intelligence of teachers. The study concluded that teachers working in government school had better emotional intelligence, occupational aspiration and highly satisfied with their job as compared to private school teachers.ThesisItem Open Access Studies on the effect of manure and biofertilizers on seed production of carrot (Daucus carota var. atrorubens)(CCSHAU, Hisar, 2021-07) Monika; Makhan LalCarrot (Daucus carota var. atrorubens) belonging to family Umbelliferae with chromosome number 2n=18 is a popular cool season vegetable and is one of the important root vegetable crops. The inflorescence, typical of the Umbelliferae, is a compound umbel. In India, root to seed is the standard method used for the production of high quality seed as this method allows the selection of healthy and true to type roots for the planting of stecklings. Organic seed production includes growing of seed crops by a collection of guidelines that prohibit the use of synthetic products/ chemicals. The present study was conducted at Seed Research Area of Department of Vegetable Science, Chaudhary Charan Singh Haryana Agricultural University, Hisar during spring-summer season of 2018-19. The objectives of the investigation were to study the effect of manure and biofertilizers on growth, seed yield and quality parameters of carrot seed crop.
