Effects of Seed Invigoration Treatments with Bio-priming on Germination, Vigour and Seedling Growth in Black Gram (Vigna mungo L.)

A study had been conducted in black gram to observe the effect of different seed invigoration treatments with bio-priming for germination, seedling growing and vigour. The variety i.e., Uttara, was selected treated control (T1); Seeds soaked distilled water/ hydropriming (T2); Rhizobium leguminosarum 10% (T3); 15% (T4); 20% (T5); 25% (T6); 30% (T7) respectively. Treated seeds were grown glass plate patri at Seed Testing Laboratory, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal, India. followed by T4 found very effective germination vigorous seedlings. Higher percentage (82.60), shoot length (17.89 cm), root (12.99 fresh weight (1.87 g), dry (0.19 vigour index I (2393.62) II (15.96) results observed bioprimed 20%. treatment recorded better performance than rest all characters observed. present investigation clearly depicted that growth revalidated lots can be improved pre-sowing treatments.
