Abstract:

Seed coating formulations developed in Department of Seed Science and Technology, was studied for their effect on seed germination and seedling vigour of ribbed gourd seeds. The seeds   were subjected to seed coating with newly developed seed coating polymer formulations (I & II), in varied dosages and subjected to seed germination and seedling growth test in paper media and raised bed conditions. The seeds were also subjected to storage in ambient conditions along with control and assessed for effect on shelf life of seeds after six months of storage. The seeds coated with the recommended dosage of newly developed seed coating polymer formulation were subjected to sowing in sand media with a sub-optimal moisture level of (40 % WHC). In raised bed conditions, a per cent improvement of 15 per cent was recorded in formulation I @ 4g kg-1, over control. The speed of germination, root length, shoot length, dry matter production and vigour index were found to record a per cent improvement of 33, 42, 29, 15 and 32 respectively, over control. The same treatment was found to record 92 per cent germination after 6 months of storage while the control recorded only 66 per cent. The seedling vigour was also concomitantly higher in coated seeds. Under moisture stress conditions (40 per cent WHC),   ribbed gourd seeds recorded 34 per cent improvement  in formulation I @ 4g kg-1, over control seeds. The vigour of the seedlings as measured by the dry matter production (mg seedling-10), was found to record 7 per cent improvement   in coated seeds of ribbed gourd crops. In the light of the results of the present study, it was concluded that seed coating formulation (I) was more effective in improving the seed germination, seedling growth parameters, seed storage potential, and seed performance in moisture stress, in ribbed gourd.
