| dc.description.abstract | ABSTRACT The present investigation titled, “Effect of nanoparticles treatment on seed quality, storability and field performance in tomato (Solanum lycopersicum L.)” was carried out as three separate experiments at experimental farm and laboratory of the Department of Seed Science and Technology, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan, HP during 2022-2023. The seeds of tomato cv. Solan Lalima were treated with three different nanoparticles (Fe2O3, MgO and ZnO) at three concentrations (10, 20 and 30 ppm) for three durations (12, 18 and 24 hrs) along with untreated seeds as control and stored in polythene bags at room temperature for 9 months. The first experiment was carried out in the laboratory to standardize the doses and duration of nanoparticle (NPs) seed treatments on seed quality parameters in tomato. In case of seeds treated with Fe2O3 nanoparticles, treatment T2, where seeds were primed with 10 ppm Fe2O3 for 18 hours, the highest germination (88.25 %), seedling length (19.85 cm), seedling dry weight (1.94 mg), seed vigour index-I (1719.00), seed vigour index-II (170.94), speed of germination (20.27) and lowest electrical conductivity (3.03 μS cm-1) were observed. In case of seeds treated with MgO nanoparticles, treatment T2, where seeds were primed with 10 ppm MgO for 18 hours, the highest germination (84.50 %), seedling length (19.45 cm), seedling dry weight (1.89 mg), seed vigour index-I (1551.10), seed vigour index-II (152.51), speed of germination (19.78) and lowest electrical conductivity (3.21 μS cm-1) were recorded. In ZnO nanoparticles treated seeds, treatment T2, where seeds were treated with 10 ppm ZnO for 18 hours, the highest germination (90.25 %), seedling length (20.43 cm), seedling dry weight (1.86 mg), seed vigour index-I (1807.23), seed vigour index-II (166.43), speed of germination (20.87) and lowest electrical conductivity (2.93 μS cm-1) values were observed. The second experiment was aimed to assess the efficiency of nanoparticle treatments in improving the storage potential of tomato seed, in which seed quality parameters were studied at different storage intervals i.e., after 0, 3, 6 and 9 month (s) of storage. In treatment T8, where seeds were treated with 10 ppm ZnO for 18 hours, the highest germination (86.94 %), seedling length (19.55 cm), seedling dry weight (1.83 mg), seed vigour index-I (1692.03), seed vigour index-II (157.26), speed of germination (20.36) and lowest electrical conductivity (3.08 μS cm-1) were noticed. Primed seeds at zero month of storage had the highest germination (84.58 %), seedling length (19.22 cm), seedling dry weight (1.81 mg), seed vigour index-I (1616.26), seed vigour index-II (153.22), speed of germination (19.00) and the lowest electrical conductivity value (3.48 μS cm-1). The third experiment which was conducted in field, seeds treated with 10 ppm ZnO for 18 hours (T8) showed maximum values with respect to plant height (162.25 cm), number of fruits cluster-1 (5.45), number of fruits plant-1 (35.8), fruit length (4.93 cm), fruit diameter (5.59 cm), fruit weight (90.67 g), fruit yield plant-1 (2.39 kg), fruit yield plot-1 (35.86 kg), fruit yield ha-1 (708.35 q) and a minimum value for days to first picking (70.33) along with maximum cost-benefit ratio (3.23). Therefore, based on above findings, nanoparticles seed treatment in tomato with ZnO @ 10 ppm for 18 hours can be recommended for better seed storability along with field performance after multilocation testing under mid-hill conditions of Himachal Pradesh. | |
