K.ThesisItem Open Access Effect of spacing and nitrogen on growth, flowering and yield of french marigold (Tagetes patula L.)(CCSHAU, 2006) Satyawan Singh; Dudi, O.P.The present study was carried out during the year 2004-2005 with a view to standardize the effect of spacing and nitrogen in French marigold (Tagetes patula L.) on growth, flowering, flower yield, seed quality and seed yield under agro climatic conditions of Haryana. To achieve these objectives an experiment was conducted with three levels of spacing (30 cm x 30 cm, 30 cm x 45 cm and 30 cm x 60 cm) and four levels of nitrogen (0, 10, 20 and 30 g m-2). The experiment on spacing and nitrogen requirement of French marigold revealed that maximum plant spread, number of branches per plant, days to bud initiation, number of buds per plant, duration of flowering, number of flowers per plant, flower yield per plant and seed yield per plant were found maximum at the spacing level of 30 cm x 60 cm in combination with a nitrogen dose of 20 g m-2 whereas, flower size, flower weight, 1000 seed weight, standard germination, vigour index-I and vigour index-II was found maximum at a spacing of 30 cm x 45 cm in combination with a nitrogen dose of 20 g m-2.ThesisItem Open Access Studies on preservation of mango products(CCSHAU, 2006) Saroj; Ashwani KumarThe present investigation was carried out at CCS Haryana Agriculural University during the year 2003-04 with the objective to find out best recipe for mango pickle and chutney and to standardized the best method for preservation of mango pickle and chutney. Four recipes were standardize for preparation of mango pickle and four recipes were tried for preservation of mango chutney. The product were assessed for the nutritional and organoleptically properties at monthly intervals for 90 days. Studies on keeping quality of mango pickles and chutney indicated significant decline in pH with corresponding rise in titrable acidity. As the storage period advanced total sugar and reducings sugar increase in both mango pickle and mango chutney. In both the mango products ascorbic acid content showed a decreasing trend throughout the storage period. Upon storage for 90 days mango pickle showed decrease in moisture content whereas mango chutney showed increasing trend in moisture content due to its hygroscopic nature. As the storage period advanced browning also increase in both the products. Mean scores for organoleptic characterstics of sweet mango pickle showed highest score and all pickles showed improvement in organoleptic acceptability with increase in storage period. Among cutneys spicy grated chutney had the highest score than that of others due to its higher acidity, total sugar, reducing sugar and overall acceptability and the mean score for organoleptic acceptability of mango chutney decreased with an increase in storage period. Both the mango products i.e. mango pickle and mango chutney were organolpetically acceptable even after 90 days of storage period and were in the category of “liking above moderate”.ThesisItem Open Access Germination and transplanting studies in aonla (Emblica officinalis gaertn.)(CCSHAU, 2006) Rashmi Kumari; Sindhu, S.S.The present investigation was carried out at the experimental orchard of Department of Horticulture CCS Haryana Agricultural University, Hisar. In the experiment, the effect of sowing time (3rd week of March and 3rd week of April) and chemicals (GA3 – 250, 500, 750 ppm; Thiourea 0.5, 1.0, 1.5% and KNO3 – 0.5, 1.0, 1.5%) on seed germination in aonla and the transplanting of budded aonla plants with earth ball and without ball during 1st week of July, August, September, January, February and March were studied During the present investigation 500 ppm GA3 was found to be the most effective treatment resulting in significant increase in seed germination (75.50%), survival percentage (83.37%), seedling height (72.94 cm), seedling girth (0.63 cm), number of branches per plant (3.13 cm), percent buddable seedling (80.44%) and early germination (8.0 days) followed by 1.0% thiourea. The seeds soaked in water also gave better performance as compared to untreated seeds. The 3rd week of March was found to be the best time of sowing of seeds as compared to 3rd week of April sowing. The transplanting of budded aonla plants with earth ball was found to be the best treatment as compared to plants without earth ball in all the months. The maximum survival percentage was obtained in plants with earth ball transplanted during 1st week of February (80.00%) followed by 1st week of July (73.30%), whereas, plants without earth ball gave maximum survival percentage when transplanted was done during 1st week of February (73.30%).
