dc.description.abstract | One soil less petri plate bioassay and a green house experiment in germination trays was carried out at College of Forestry, Ranichauri, Tehri Garhwal, Uttarakhand during 2019-2020 to investigate the effect of NaCl seed priming on germination and seedling growth of legumes under soil application of pine needle biochar. The study consisted of twelve treatments in viz; control (T1), 4% NaCl priming (T2), 6% NaCl priming (T3), 10 t/ha biochar (T4), 30t/ha biochar (T5), 50t/ha biochar (T6), 4% NaCl priming + 10t/ha biochar (T7), 4% NaCl priming + 30t/ha biochar (T8), 4% NaCl priming + 50t/ha biochar (T9), 6% NaCl priming +10t/ha (T10), 6% NaCl priming + 30t/ha biochar (T11) and 6% NaCl priming + 50t/ha biochar (T12). Complete Randomized Design was applied for analysis of data under lab and green house experiments. In the preliminary investigation under soil less petri plate bioassay, the growth parameters i.e germination %, first count, speed of germination, relative growth index and mean daily germination in ricebean, and faba bean whereas, highest speed of germination was recorded in lentil which showed significantly higher values with the treatment containing 4% NaCl priming (T2). The combination of pine needle biochar @ 10 t/ha with 4 % NaCl (T7) seed priming under soil less bioassay in petri plates showed significantly higher root length, shoot length, seedling length, fresh weight of seedlings, dry weight of seedlings, vigour index I and vigour index II in ricebean and lentil. In faba bean the NaCl seed priming with 6 % solution along with 10 t/ha pine needle biochar (T10) recorded significantly higher root length, shoot length, seedling length, fresh weight of seedlings, dry weight of seedlings, vigour index I and vigour index II in faba bean. In green house experiment under germination trays, 4% NaCl priming with 10 t/ha biochar (T7) recorded significantly higher germination percentage, root length, shoot length, seedling length, fresh and dry weight, vigour index I, vigour index II, NPK concentration and their uptake at 20 DAS in ricebean. Similar results were obtained for lentil with the exception of germination percentage which did not show significant variation among the values for different treatments. In case of faba bean, 4% NaCl priming with 50 t/ha pine needle biochar (T9) recorded higher root length, seedling length, fresh and dry weight, vigour index I & II and NPK content and their uptake at 20 DAS whereas, highest germination percentage was recorded with application of 4% NaCl priming under 30 t/ha pine needle biochar (T8). The results obtained in the present study concluded that the NaCl seed priming at lower concentration i.e 4 % solution improved the germination and seedling development of legumes viz. ricebean and lentil when used with application of 10 t/ha pine needle biochar whereas 4 % NaCl seed priming with 50 t/ha biochar has improved most of the seedling growth parameters in faba bean. However; for the conformity of these results and standardization of priming doses with pine needle biochar, long term field experiments are required to be conducted. | en_US |
