ThesisItem Open Access EFFECT OF FOLIAR APPLICATION OF KINETIN ON GROWTH, LEAF YIELD, SEED YIELD AND QUALITY ATTRIBUTES IN FENUGREEK(UHF,NAUNI, 2023-06) KULDEEP SINGH; SHARMA, RAJINDERABSTRACT The present investigation titled, “Effect of foliar application of kinetin on growth, leaf yield, seed yield and quality attributes in fenugreek” was carried out on cv. Pusa Early Bunching. Field trial was laid out in Randomized Complete Block Design (Factorial) with three replications of each treatment combination at Pandah Experimental Farm of the Department of Seed Science and Technology, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during rabi 2021-22. The treatments comprised of three stages of application viz. S1 (45 DAS), S2 (60 DAS) and S3 (75 DAS) and three kinetin doses (D) i.e., D1 (25 ppm), D2 (50 ppm) and D3 (75 ppm), thus, making nine treatment combinations along with control. Observations were recorded on different aspects of growth, seed yield and quality. From the present study, it was concluded that treatment combination D3S1 (6-BA @ 75 ppm 45 DAS) was highly significant recording minimum days ( 82.00) to first leaf cut after sowing, maxima for branches plant-1 (8.03), leaf yield at first cut (0.807 kg plot-1) and total leaf yield (1.71 kg plot-1 and 84.41q ha-1), minimum days to 50 % flowering (105.67), maximum values for plant height (47.24 cm) at harvesting stage, pods plant -1 (24.04 ), pod length ( 10.36cm), number of seeds pod-1 ( 13.06), weight of 25 pods (7.35g), seed yield (0.24 kg plot-1 and 11.85q ha-1), test weight (11.31g), nodules plant-1 (4.84 ) after pod harvest, dry matter (15.11g) plant-1, harvest index (29.05%) and biological yield ( 40.78q ha-1). Under laboratory conditions, maxima were recorded for germination of harvested seed (94.18%), seedling length (23.37cm), seedling dry weight (43.63 mg), seed vigour index-I (2200.75), seed vigour index-II (4108.91 and minimum seed electrical conductivity (0.086 dS m-1) assessed using CRD being significantly superior over all other treatment combinations. This treatment combination also ensured highest B: C ratio (3.74: 1) for leaf and (0.74: 1) for seed production. Hence, treatment combination D3S1 (6-BA @ 75 ppm 45 DAS) can be recommended for production of green leaves and higher yield of quality seed after multi-location testing under mid-hill conditions of Himachal Pradesh.ThesisItem Open Access STUDIES ON THE EFFECT OF MICRONUTRIENTS ON SEED YIELD, QUALITY AND NUTRIENT UPTAKE IN TURNIP(UHF,NAUNI, 2023-01) PANGHAL, PRASHANT; SHARMA, RAJINDERABSTRACT The present investigation titled, “Studies on the effect of micronutrients on seed yield, quality and nutrient uptake in turnip” was undertaken at Pandah Experimental Farm of the Department of Seed Science and Technology, Dr Y S Parmar University of Horticulture and Forestry Nauni, Solan HP during rabi season of 2021-2022 using turnip cv. Purple Top White Globe. There were eighteen treatment combinations which included three levels each of zinc (0, 300 and 400 ppm ZnSO4) and manganese (0, 100 and 200 ppm MnSO4) along with two stages of application (45 and 60 DAT) replicated thrice in RBD. Each plot of size 1.8 × 1.8 m accommodated twenty four plants at a spacing of 45 × 30 cm. The results revealed that out of 18 treatment combinations, ZnSO4 @ 400 ppm + MnSO4 @ 200 ppm at 45 DAT was best for growth parameters resulting in maximum plant height (155.65 cm) and plant spread (82.17 cm). On the other hand, treatment combination ZnSO4 @ 400 ppm + MnSO4 @ 200 ppm at 60 DAT outperformed rest of the interactions by registering maxima for number of siliquae plant-1 (1238.07), siliqua length (8.28 cm), number of seeds siliqua-1 (22.63), seed yield (21.19 g plant-1, 341.29 g plot-1 and 842.68 kg ha-1), plant biomass (45.87 q ha-1), 1000 seed weight (1.82 g), speed of germination (12.58), germination (94.86 %), seedling length (18.90 cm), seedling dry weight (11.57 mg), seed vigour index-I (1792.54), seed vigour index-II (1088.61) along with lowest figures for seed electrical conductivity (0.025 dS m-1) and days to seed maturity (120.46). This treatment combination also ensured highest B: C ratio (2.49: 1). Similarly, highest levels of both the micronutrients tested recorded significantly higher leaf and seed nutrient content (Zn and Mn); though there interaction could not influence these traits. Hence, foliar spray of ZnSO4 @ 400 ppm + MnSO4 @ 200 ppm at 60 DAT can be recommended for higher seed yield and quality of turnip under mid-hill situation of Himachal Pradesh after multi-location testing.
