Abstract
The Laboratory experiment was performed at Seed Testing Laboratory, Department of Agronomy, Sindh Agriculture University, Tandojam during Spring 2016 to observe “germination and seedling growth of soybean under the impact of seed soaking with FertigrainStart (amino acid product) and water for different periods. The experiment was laid out in completely randomized design with three replications. The seed of soybean variety Rawal was used throughout the experiment. The treatments included untreated (Control),Fertigrain Start @ 2 ml kg-1 seed, Fertigrain Start @ 4 ml kg-1 seed, Water Soaking (1 hour),Water Soaking (2 hour),Fertigrain Start @ 2 ml kg-1 seed+Water Soaking (1 hour),Fertigrain Start @ 2 ml kg-1seed+Water Soaking (2 hour),Fertigrain Start @ 4 ml kg-1 seed+Water Soaking (1 hour) and Fertigrain Start @ 4 ml kg-1 seed+Water Soaking (2 hour). The statistical analysis of data showed that germination and growth of soybean were significantly (P<0.05) affected by Fertigrain Start and water soaking. The results indicated that the maximum germination (%), root length, shoot length, leaves seedling-1,root fresh weight and shoot fresh weight were observed in Fertigrain Start @ 4 ml kg-1 seed+Water Soaking (2 hour)followed by Fertigrain Start @ 4 ml kg-1 seed+Water Soaking (1hour), Fertigrain Start @ 2 ml kg-1 seed+ Water Soaking (2 hour) and Fertigrain Start @ 2 ml kg-1 seed+Water Soaking (1 hour) with non-significant (P>0.05) statistical differences. However, application of Water Soaking (2 hours), Fertigrain Start @ 2 ml kg-1 seed, FertigrainStart @ 4 ml kg-1 seed and Water Soaking (1 hour) ranked 2nd, 3rd, 4th and 5th in almost all traits studied. However, minimum germination (%), root length, shoot length, leaves seedling-1, root fresh weight and shoot fresh weight were noted under control. Hereafter, it is concluded from the results that application of Fertigrain Start @ 2ml kg-1 seed+Water soaking (1 hour) proved appropriate for obtaining optimum germination and subsequent growth of soybean.
