Effect of Priming on Seed Germination Characteristics of Spring Rice (Oryza sativa cv. Hardinath Hybrid-1) in Chandrapur, Rautahat, NEPAL

Abstract

To determine the effects of different priming on Germination and Seedling Characteristics of Spring rice (Oryza Sativa L.), an experiment was carried out at Chandrapur municipality-4, Rautahat during March of 2022 with Seven different treatments viz. T1 Potash (3% Solution), T2 Urea (3% Solution), T3 DAP (3% Solution), T4 Halo (1Mole Nacl/Litre), T5 Zinc (3% Solution), T6 Hydro and T7 Control. The experiment was laid out in simple CRD design with three replications. Hardinath Hybrid-1 Variety was used for the experiment. Observations on Germination %, Germination Energy (%), Speed of Germination (%), Vigor Index, Root and Shoot Length, Fresh Weight of Seedlings and Dry Weight of Seedlings were considered. Data was entered and tabulated using MS-Excel, while Analysis of variation and mean separation was done using R-Studio. Biometrical Observation like germination Energy was found highest under the treatment DAP (82.67). The germination percentage (93.00) and vigor index (161.4) was found highest in DAP (3%) Priming and speed of germination (86.84) was found highest in Potash Priming. Similarly, root length (6.14cm) and shoot length (6.23cm) was found to be highest in DAP treatment followed by Halo treatment with root length (5.30cm) and shoot length (5.44 cm). At 10th and 15th Day, there is significant effect on root length while there are no significant differences/effect on Shoot length, fresh weight and Dry Weight. Among these priming treatments, the highest root length was found in priming of DAP; 7.84 cm and 8.07 cm.
