ThesisItem Unknown Effect of biostimulants and biofertilizers on growth, flowering and physio-chemical properties of rose cv. Laher(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2009-01) Rana, Manju; Santosh KumarThe present studies entitled “Effect of Biostimulants and Biofertilizers on Growth, Flowering and Physio-chemical properties of rose cv. Laher” was carried out during October 2006 to November 2008 at Model Floriculture Centre, Department of Horticulture, G.B. Pant University of Agriculture and Technology, Pantnagar. The experiment was laid out in a completely randomized block design with 18 treatments replicated thrice with sixteen plants per replication. The treatments combinations consisting of inorganic fertilizers, biofertilizers (Common basal dose) and biostimulants (namely, Manchurian mushroom tea and Panchgavya). Plants grown in Common basal dose + vermicompost (500 g/m2) + 3% Panchgavya + 3% Manchurian mushroom tea recorded maximum diameter of rootstock, number of flowering shoots per plant, number of flowers per plant, leaf area per plant, number of leaves per plant, flower longevity and soil organic carbon content. Treatment consisting of 50% recommended dose of fertilizers + vermicompost (500 g/m2) + 3% Panchgavya + 3% Manchurian mushroom tea was effective in increasing plant height, bud diameter, bud length, flower stem length, flower size, average fresh and dry weight of flower and duration of flowering. Maximum soil NPK was observed in media containing recommended dose of NPK (T1). Treatment consisting of Common basal dose + vermicompost (500 g/m2) + 3 % Panchgavya + 3 % Manchurian mushroom tea was effective in increasing leaf NPK content.ThesisItem Open Access Effect of pre-harvest application of antioxidants on storage life and quality of plum (Prunus salicina Lindl.) cv. Satluj Purple(Punjab Agricultural University, Ludhiana, 2019) Rana, Manju; Jawandha, S.K.The aim of present investigation entitled “Effect of pre-harvest application of antioxidants on storage life and quality of plum (Prunus salicina Lindl.) cv. Satluj Purple” was to extend the post-harvest life and maintenance of quality of plum fruits under cold storage conditions. The research was conducted in Department of Fruit Science, Punjab Agricultural University, Ludhiana. The healthy plum trees were sprayed with sodium nitroprusside (SNP) @ 50, 100 and 150 μmolL-1 and salicylic acid (SA) @ 1, 2 and 3 mmolL-1 before 7 and 14 days of harvest. The fruits were harvested at colour break stage, packed in corrugated fibre board (CFB) boxes and stored at low temperature (0-1ºC and 90-95% RH).The various physicochemical observations were recorded after 7, 14, 21, 28 and 35 days of storage. The results revealed that the fruits treated with 100 μmolL-1 sodium nitroprusside (SNP) and 150 μmolL-1 sodium nitroprusside (SNP) 14 days before harvest effectively prolonged the storage life of fruits by minimizing the physiological loss in weight, spoilage, the actitvities of fruit softening enzymes (pectin methyl esterase and cellulase) and maintaining higher firmness, sensory quality, all sugars (total sugars, reducing sugars and non-reducing sugars), titratable acidity, total soluble solids (TSS), total antioxidant activity, total phenols and flavonols content under low temperature storage conditions.ThesisItem Open Access Field Applicability Of Child Development Practices Package Of Practices For Haryana(I.C College Of Home Science Chaudhary Charan Singh Haryana Agricultural University Hisar, 1988) Rana, Manju; Verma, T.
