Impact of Storage Material on Seed Quality and Seed Health Parameters of Treated Seeds of Soybean [Glycine maxL Merill]

Soybean [Glycine max L Merill] is an important oil seed crops known for its richest protein
source and is a miracle crop of twenty century as it plays a pivotal role in agriculture, industry
and export trade of India. Maintenance of seed viability from harvest to next planting season is a
major constraint in soybean production. Among the three storage materials viz., gunny bag,
polylined gunny bag and Purdue Improved Crop storage (PICS) bag evaluated with the seeds
treated with carboxin+thiram @3g/kg, pyraclostrobin+ metiram @ 2g/kg and carbendazim
+mancozeb @ 2g/kg with untreated control for seed viability, soybean seeds when treated with
carboxin 37.5% +thiram 37.5% @3g/kg and stored in polylined gunny bag was found
significantly superior in maintaining germination (77.17%) at above IMSCS with highest
seedling vigour (1871) and absolutely nil seed infections up to eight months of storage followed
by seeds treated with pyraclostrobin+ metiram @ 2g/kg and stored in polylined gunny bag under
ambient conditions. Similarly, in case of untreated soybean seeds the polylined gunny bag
exhibited improved germination (14.01%) and seedling vigour (19.77%) with reduced seed
infections (46.5%) when compared to gunny bags at six months after storage.The present
research findings revealed that of the storage materials, the polylined gunny bag was found
effective to maintain the seed health and quality of soybean seeds during storage.
