The study was administered to research the consequences of Sulphuric acid concentration treatment and therefore the predicament treatments on the germination pattern of breaking of seed dormancy in Macrotyloma uniflorum (Lam.) Verdc. (Horse gram), Cicer arietinum (L.) (Chick pea) and Vigna radiata (L.) Wilczek. (Green gram). Twelve (12) seeds of Macrotyloma uniflorum (Lam.) Verdc (Horse gram), Cicer arietinum (L. ) (Chick pea) and Vigna radiata (L.) Wilczek., (Green gram) are taken in a clean petri-dish and that they were used. The germination percentage was noted in seeds treated with fifty (50%) percent Sulphuric acid (vitriol) within a sixty (60) minutes soaking period. Germination was observed to be enhanced by the effect of vitriol on disrupting the seed coats of, Macrotyloma uniflorum (Lam.) Verdc (Horse gram), Cicer arietinum (L.) (Chick pea) and Vigna radiata (L.) Wilczek., (Green gram) followed by hot water (predicament) treatment too. Determine the breaking dormancy from the first (1st) day up to fifth (5th) day. Note the breaking of seeds during every day and tabulate it. Results of this research may function as useful information within the production and improvement of the species, as knowledge on seed germination requirements may be a critical factor about seedlings production. As a result of this project, on the 5 th day, the seeds of Vigna radiata (L.)Wilczek.,. shows higher germination percentage in both hot water treatment and Sulphuric acid treatment. Rest of the seedsshow the minimum germination percentage on the 5thday. Keywords: Seed dormancy, Hot water treatment and Sulphuric acid conc. treatment. ABSTRACT RESEARCH ARTICLE
