Blackgram (Vigna mungo L.) is one of the most important legume crops, grown all around the world. It is used as a vegetable, feed, food and fodder purpose. Blackgram has lower germination and production because of its hard outer covering. To improve germination and seedling vigour, priming alters the physiological state of the seed. This change may improve germination uniformity, increasing seed vigour or physiology. Primed seeds generate seedlings that germinate faster and more uniformed than unprimed seeds and these early seedlings are frequently more robust and resistant to biotic and abiotic stresses. This is a time-saving and low-cost strategy that farmers may employ to improve crop stand and productivity while reducing cost.
The experiment was carried out in 2016-2017 at Department of Genetics and Plant Breeding, SHUATS, Prayagraj. Blackgram (var. PU-31) seeds were primed with Hydro, Halo, Osmo and Organic priming at 12 hours. Then, four replications of the Complete Randomized Block Design were used to test seeds for germination and vigour.
The experimental results indicated that seed primed with PEG6000@ 20% had the highest germination, seedling length and vigour indices, followed by CaCl2@ 1%, when compared to control and other treatments.
