| dc.description.abstract | The field and laboratory experiments were conducted at Agricultural Research Station, Hagari and Department of Seed Science and Technology, College of Agriculture, University of Agricultural Sciences, Raichur during rabi 2019-20. The first experiment was laid down in Completely Randomized Design (CRD) with four replications to standardize the hydro-priming duration where the seeds were soaked at different durations from 0 to 24 h with 4 h interval for three varieties viz., SPV-2217, GS-23 and M 35-1. The results recorded significantly highest germination (89.55, 86.71 and 91.33 %, ), shoot length (17.10, 14.66 and 17.60 cm), root length (18.31, 14.02 and 19.03 cm), seedling length (35.41, 28.69 and 36.63 cm), seedling dry weight (302.66, 239.14 and 349.00 mg) and seedling vigour index I (3174, 2500 and 3346) and seedling vigour index II (27205, 20883 and 31890) for seeds soaked in 12 h (T3) duration in variety GS-23 (V2) and in combination of seeds soaked in 12 h in cv. GS-23 (T3V2). The second experiment was carried out to study the effect of seed bio priming on plant growth, yield and quality attributes in sorghum varieties. In the present study, the experiment consists of nine priming treatments viz., Hydro priming, Azospirillum brasilense (20 %), Pseudomonas fluorescence (20 %), Phosphobacteria (20 %), Trichoderma harzianum (1 %), Beejamrutha (50 %), Vermiwash (2 %), Vihaan (5 %) , Waste decomposer (20 %) with three cultivars viz., SPV-2217, GS-23 and M 35-1. Significantly higher plant height at 30 DAS (68.13, 60.56 and 70.30 cm), 60 DAS (202.83, 191.05 and 209.50 cm), 90 DAS (249.50, 244.64 and 253.70 cm) and at harvest (253.00, 246.81 and 257.00 cm), panicle length (20.28, 19.05 and 23.15 cm), panicle weight ( 35.36, 29.42 and 37.30 g), test weight (31.89, 32.97 and 34.30 g), seed yield (2318.82, 2116.41 and 2540.53 kg ha-1), fodder yield (8673.77, 7523.37 and 9243.56 kg ha-1) and BC ratio (1.84, 1.67 and 2.01) were recorded in seed priming with Pseudomonas fluorescence (20 %) (T2), cv. GS-23 (V2) and in combination of seed priming with Pseudomonas fluorescence (20 %) in cv. GS-23 (T2V2). Similarly, the seed quality parameters viz., germination (91.44, 89.37 and 93.33 %), shoot length (19.33, 17.71 and 20.20 cm), root length (17.59, 15.80 and 18.70 cm), seedling length (36.92, 33.52 and 38.90 cm), seedling dry weight (307.33, 282.55 and 347.00 mg), seedling vigour index I (3379, 3005 and 3631) and seedling vigour index II (28174, 25390 and 32381) recorded significantly higher in seed priming with Pseudomonas fluorescence (20 %) (T2), cv. GS-23 (V2) and in combination of seed priming with Pseudomonas fluorescence (20 %) in cv. GS-23 (T2V2) respectively. | |
