Comparison of Near Nano Size and Commercial Grade Botanicals with Shaking and without Shaking on Seed Quality Attributes of Soybean (Glycine max L.) cv. CO 3 Seeds

Background: Soybean is important oil seed crop. Poor seed germination is a major constraint for increasing the productivity of soybean. Seed quality enhancement will enhance the germination. Treating the seeds with chemicals may cause harmful effects to ecosystems and also to human beings. Using botanicals for seed treatment is safe. The present study was taken with a view to assess the seed quality of soybean by using different botanicals treatments (ball milled and commercial grade) along with shaking and without shaking.
Methods: Experiment was conducted to evaluate the effect of seed treatment with different ball milled botanicals and commercial grade along with shaking (60 min) and without shaking of soybean seeds on quality attributes. Botanical powders of fenugreek (Trigonella foenum-graecum L.) seed, leafs of ashwagandha (Withania somnifera), tea (Camellia sinensis) and noni (Morinda citrifolia) were ball milled for 1 h to bring into near nano size and treated with seeds @ 2 g kg-1 for 60 min. Without ball milling was served as commercial grade. Among these two methods (commercial grade and near nano size) highest values were observed in seeds treated with near nano size powder. Generally shaking of seeds with botanicals was performed better than without shaking. Result: In this experiment, botanical fenugreek seed powder perfrmed well. In interaction, soybean seeds treated with near nano size fenugreek seed powder @ 2 g kg-1 with shaking of 60 min showed highest seed quality parameters. The per cent increase over control for germination, shoot length, root length, dry matter production and vigour index were 17.8, 27.7, 43.9, 47.6 and 45.3%, respectively.
