Abstract:
This research was conducted to determine the effects of TSP polymer and with different biostimulants at various concentrations (such as panchagavya - 0.3, 0.6, 1.2 ml, vermiwash - 0.3, 0.6, 1.2 ml and humic acid – 0.12, 0.3, 0.6 g per 6g of polymer) on seed germination and seedling growth of black gram during 2021, under laboratory condition at department of seed science and technology, Tamil Nadu Agricultural University. The seeds of black gram var. VBN 8 were treated with TSP polymer (6g/kg of seeds), TSP polymer (6g) + panchagavya (0.3 or 0.6 or 1.2 ml), TSP polymer (6g) + vermiwash (0.3 or 0.6 or 1.2 ml) and TSP polymer (6g) + humic acid (0.12 or 0.3 or 0.6 g). Untreated seeds were served as control. The results showed non-significant difference for 1000 seed weight and seed moisture content. Seeds coated with TSP polymer + 0.3 g humic acid significantly increased the seed germination (90%) and seedling growth parameters compared to other treatments. It significantly reduced the abnormal seedling (4%) and dead seed (6%) percentage, besides it favours the uniform germination. The results concluded that black gram seeds (one kg) coated with TSP polymer (6g) + 0.3g humic acid performed better seedling establishment and could be recommended as pre sowing seed treatment.
