Influence of Pre-sowed Biochemical, Chemical and Organic Treatments to the Germination, Vigor and Morphological Growth of Tamarindus indica L
Year: 2025
Type: article
Abstract: This study evaluated the effects of pre-sowing biochemical and organic treatments on the germination and early growth of Tamarindusindica L., a species with hard seed dormancy. Conducted during the 2024–2025 Kharif season in Bemetara, Chhattisgarh, the experiment tested 11 treatments including gibberellic acid (GA₃), potassium nitrate (KNO₃), cow urine, and cow dung slurry under a Completely Randomized Design.Gibberellic acid at 150 ppm (T₇) was the most effective, significantly enhancing all growth parameters: fastest germination (4 days), highest germination rate (96%), tallest seedlings (72 cm), and highest vigour index (7258). Organic and nitrate treatments also improved performance over the control but were less effective than GA₃.The results support GA₃ @150 ppm as a highly effective dormancy-breaking treatment for tamarind seeds and recommend its use in nursery and while suggesting organic alternatives as eco-friendly, cost-effective options.
