ThesisItem Open Access Effect of different levels of salinity on young plants of guava(CCSHAU, Hisar, 2023-03) Anil; Goyal, R.K.The experiment entitled "Effect of different levels of salinity on young plants of guava" was carried out in pots at screen house, Department of Horticulture CCS HAU, Hisar during the year 2020 to 2021. The experiment was conducted in Factorial Completely Randomized Block Design (FCRD) i.e., factor A as four guava cultivars were selected i.e., Hisar Safeda, Hisar Surkha, Allahabad Safeda and Lucknow 49; and factor B as nine different chloride salinity (EC) levels (dSm-1) -(Control 0.07 dSm-1, 1.0 dSm-1, 2.0 dSm-1, 3.0 dSm-1, 4.0 dSm-1, 5.0 dSm-1, 6.0 dSm-1, 7.0 dSm-1 and 8.0 dSm-1) and replicated 5 times with one plant per replicationof each cultivar. The leaf number, plant height (cm), stem diameter (cm), internodal distance (mm) and root length (cm) (63.96, 107.92, 14.39, 33.73 and 18.90, respectively) were recorded significant under L-49 cultivar at 31st December among all the 4 cultivars. The significantly lower number of affected leaves per plant and number of dead leaves per plant as compared to other cultivars (42.31 and 5.56) was recorded in L-49. Among different salinity levels at 31st December control 0.07 dSm-1 recorded significantly more leaf number, plant height (cm), root length (cm), shoot length (cm) and dry weight of plant (g) (81.20, 116.28, 19.32, 97.29 and 34.36, respectively). Similarly, significantly lower number of affected leaves per plant and number of dead leaves per plant were in control 0.07 dSm-1 as compared to other salinity levels (25.40 and 2.25). The higher nitrogen, phosphorous, potassium contents in plant and soil were recorded in L-49 cultivar and control 0.07dSm-1 as compared to other treatments.Hence it could be concluded that L-49 cultivar expressed better tolerance at various chloride salinity levels as compared to other varieties whereas, control 0.07 dSm-1 treatment showed better results for different characters observed.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 Effect of organic source of nutrients on growth, yield and quality of strawberry (Fragaria x ananassa)(CCSHAU, Hisar, 2023-07) Modi, Nanak; Suresh KumarAn experiment was conducted to study the “Effect of organic source of nutrients on growth, yield and quality of strawberry (Fragaria x ananassa)” at Deendayal Upadhyay Centre of Excellence for Organic Farming, Chaudhary Charan Singh Haryana Agricultural University, Hisar during 2022-2023. The experiment was laid out according to Randomized Blocks Design with fourteen treatment replicated thrice. The result reveals that the maximum plant height (21.06 cm), plant spread (23.89 cm), number of leaves (18.69), leaf area (78.45 cm2), crown diameter (1.40 cm), internodal length (7.09 cm), number of flowers/plant (19.58), number of fruits/plant (17.71), number of fruits/truss (4.89), berry length (3.85 cm), berry breadth (2.84 cm), berry weight (14.74 g), marketable fruit (83.04%), number of harvest (5.73), yield/plant (260.93 g), TSS (9.16 oBrix), TSS/acid ratio (14.77), ascorbic acid (58.30 mg/100 gm), anthocyanin (63.72 mg/100 gm), leaf nitrogen content (3.20%), phosphorus content (1.20%) and potassium content (3.07%) were recorded in plants treated with treatment T9 (Vermicompost + Azotobacter + PSB). The minimum days taken in flowering (54.77 days) and minimum titratable acidity (0.62%) were also recorded in treatment T9 (Vermicompost + Azotobacter + PSB). Considering overall performances, the study revealed that the combined application of Vermicompost and biofertilizer could be a good source of plant nutrients for organic strawberry cultivation.ThesisItem Open Access Effect of pre harvest sprays of calcium on yield, quality and shelf life of guava(CCSHAU, Hisar, 2023-08) Rajat; Sharma, Jeet RamThe present investigation entitled “Effect of pre harvest sprays of calcium on yield, quality and shelf life of guava” was carried out at the experimental orchard and PG lab of the Department of Horticulture, CCS Haryana Agricultural University, Hisar during rainy and winter season of 2022-23. A Randomized Block Design (RBD) with ten treatments, each replicated three times, was employed to examine the influence of different calcium compounds on guava cv. Hisar Safeda. Thirty uniform plants were selected for data collection and subjected to sprays of varying concentrations of CaCl2 (0.5%, 1.0%, and 1.5%), Ca(NO3)2 (0.5%, 1.0%, and 1.5%), and CaSO4 (0.5%, 1.0%, and 1.5%) one month prior to harvesting. The study revealed that different treatments had a significant impact on all measured parameters in terms of both quantitative and qualitative assessment of the fruits. It was observed that there was increase in decay loss, PLW and specific gravity with the advancement of storage period, during both the seasons, independent of the treatments applied. On the other hand, moisture content and fruit firmness were found to decrease with passage of storage time, regardless of treatments during both the seasons. The organoleptic ratings also decreased as the storage period progressed in all treatments. Notably, the change in colour from yellowish-green to yellow during storage was relatively gradual in the trees treated with calcium nitrate (1.5%). Among treatments, calcium nitrate (1.5%) exhibited highest number of fruits per tree, maximum fruit weight, maximum yield, TSS, TSS: Acid ratio, reducing sugars, non-reducing sugars, total sugars, moisture content, specific gravity, physiological loss in weight, decay loss and maximum organoleptic ratings in both the seasons while, fruit firmness, ascorbic acid, pectin and phenol content were found to be maximum in the calcium chloride (1.5%) treatment. It was also observed that winter season fruits of all the treatments were much more superior to rainy season fruits.ThesisItem Open Access Effect of integrated nutrient management on growth, yield and quality of guava (Psidium guajava L.) cv. Hisar Safeda(CCS HAU, Hisar, 2023-07) Kuldeep Kumar; Manender SinghThe present investigation was carried out to study the “Effect of integrated nutrient management on growth, yield and quality of guava (Psidium guajava L.) cv. Hisar Safeda” in the Department of Horticulture, CCS Haryana Agricultural University, Hisar during 2022-23. The experiment comprised of twelve different treatments with three replications and were laid out in randomized block design (RBD) to assessed the effect of integrated nutrient management on growth, yield and quality of guava. The results revealed that all the integrated nutrient treatments at different doses had significantly influenced growth, yield, physical and quality parameters over absolute control. Among different treatments, for yield parameters, T7 (100 % NPK (RDF) + ZnSO4 (0.5 %) + B (0.2 %) + Fe (0.5 %) as foliar spray + bio-fertilizer) performed better in terms of number of fruit/plant (256.5), average fruit yield (42.45 kg/plant). Furthermore, physical parameters, T7 (100 % NPK (RDF) + ZnSO4 (0.5 %) + B (0.2 %) + Fe (0.5 %) as foliar spray + bio-fertilizer) was found better in terms of diameter of fruit (7.08 cm), length of fruit (6.99 cm), average seed weight (1.95 g), fruit volume (168.6 cc). Moreover, for quality parameters, T7 performed better in terms of TSS (12.98 oB), acidity (0.36 %), TSS/Acid ratio (36.06) and sugar content i.e. total sugar (7.74 %), reducing sugar (4.62 %) and non reducing sugar (3.12 %), pectin content (0.97 %), and ascorbic acid content (200 mg/100 g pulp). However, parameters i.e. specific gravity were observed non-significant means all the treatments at different doses were not significantly influenced this traitsThesisItem Open Access Effect of different planting time and mulching on growth and flowering of tuberose(CCSHAU, Hisar, 2023-07) Raju; Chahal, DevenderThe present investigation entitled, “Effect of different planting time and mulching on growth and flowering of tuberose (Polianthes tuberosa L.)” was conducted during 2022-2023 at the Research Farm of Agri-tourism Centre of CCS HAU Hisar (Haryana). The experiment was laid out in split plot design with four planting dates viz. 15th April, 27th April, 10th May, and 25th May and five mulch treatments viz. wheat straw mulch, silver- black plastic mulch, white polyethylene mulch, newspaper mulch and no mulch (control). In the present study, most of the growth, floral and bulb parameters were significantly influenced by the dates of planting and application of mulch materials, but their interaction was observed non-significant. Among different planting dates, crop planted on 15th April performed better in terms of most of the growth, development, flowering and bulb parameters and it was closely followed by crop planted on 27th April in qualitative parameters as compared to later dates of planting. In general, mulching improved the production and quality of spikes, bulbs as well as bulblets, but the higher net returns over un-mulched was observed with wheat straw mulch and silver-black plastic mulch. Further, the silver-black plastic mulch was found most effective in reducing the population of weeds, the mulching of wheat straw (3‟‟ thick) was observed most effective in the production of marketable spikes, sizeable bulbs, bulblets and the higher net return and B:C ratio. Earlier sprouting, earlier flowering, longest spike and highest number of florets on spike were the additional benefit of wheat straw mulch.ThesisItem Open Access Impact of plant growth regulators on growth, yield and quality of guava (Psidium guajava L.) cv. Hisar Safeda in winter season(CCS HAU, Hisar, 2022-07-15) Pravesh Kumar; Manender SinghThe present investigation was carried out to study the “Impact of plant growth regulators on growth, yield and quality of guava (Psidium guajava L.) cv. Hisar Safeda in winter season” in the Department of Horticulture, CCS Haryana Agricultural University, Hisar during 2021-22. The experiment comprised of ten different foliar treatments with three replications and were laid out in randomized block design (RBD) to assessed the effect of plant growth regulators on growth, yield and quality of guava. The results revealed that all the plant growth regulator treatments at different concentrations had significantly influenced yield, fruit development and quality parameters over absolute control. Among different treatments, for yield parameters, T6 (NAA at 100 ppm) performed better in terms of fruit set (56.73 %) whereas, T9 (GA3 at 100 ppm) observed better for fruit retention (59.85 %), fruit drop (40.17 %), no. of fruits per plant (364.52) and yield (65.49 kg/plant). Furthermore, for fruit development parameters, T9 (GA3 at 100 ppm) was found better in terms of diameter of fruit (7.23 cm), length of fruit (7.20 cm), average fruit weight (179.67 cm), average seed weight (3.21 g), fruit volume (179.22 cc). Moreover, for quality parameters, T6 (NAA at 100 ppm) performed better in terms of TSS (14.53 oB), acidity (0.31 %), TSS/Acid ratio (46.87) and sugar content i.e. total sugar (7.84 %), reducing sugar (4.63 %) and non-reducing sugar (3.21 %) while, T9 (GA3 at 100 ppm ) recorded better for pectin content (0.98 %), firmness of fruit (6.08 kg/inch) and ascorbic acid content (196.59 mg/100g pulp). However, parameters i.e. specific gravity and days to maturity were observed non-significant means all the treatments at different concentration were not significantly influenced these traits.ThesisItem Open Access Effect of floral preservatives and growth regulators on post harvest quality and vase life of tuberose(CCSHAU Hisar, 2022-08) Nasima; Sonu KumariThe present investigation entitled "Effect of floral preservatives and growth regulators on post harvest quality and vase life of tuberose” was carried out at laboratory of Department of Horticulture, CCS Haryana Agricultural University, Hisar during the year of 2022. Fifteen treatment combinations consisting of seven chemicals viz., sucrose (2% and 4%), citric acid (250 mg/l and 350 mg/l), silver nitrate (25 mg/l and 50 mg/l), aluminium sulfate (150 mg/l and 300 mg/l), gibberellic acid (100 mg/l and 150 mg/l), benzyal adenine (100 mg/l and 150 mg/l) and salicylic acid (100 mg/l and 150 mg/l) along with control (distilled water) were used in Completely Randomized Design with three replications. The vase solution of 4% sucrose + 150 mg/l salicylic acid (SA) was found promising in terms of number of opened florets per spike, percentage of opened florets per spike, freshness index, spike weight at wilting of 3rd floret, floret diameter, vase life and water uptake. This treatment was also found significant in reducing number of unopened florets per spike, water loss/water uptake ratio, physiological loss in weight and proximal end browning. However, the minimum days to opening of 3rd floret and number of florets open at a time was recorded in 4% sucrose +300 mg/l aluminium sulfate treatment.ThesisItem Open Access Influence of bio- inoculents in combination with organic manures on fresh on seed germination and seedling growth of fresh and aged seeds of guava(Chaudhary Charan Singh Haryana Agricultural University hisar, 2022-09) Reenu devi; Reenu devi; Sharma, Jeet Ram; Sharma, Jeet RamThe present investigation was carried out to study the effect of pre-sowing treatments on seed germination and seedling growth of guava (Psidium guajava L.) in the Department of Horticulture, CCS Haryana Agricultural University, Hisar during 2021-22.
