Abstract:
Allelopathic effects of aqueous leaf extracts of Jatropha curcas on seed germination and early seedling growth of wheat cv. Inqlab-91 were investigated. The extracts were applied at 50%, 25%, 12.5%, 6.25% and 3.12% as seed soaking for 5h prior to sowing of seeds in the pots. The J. curcas leaf characterized for composition of macronutrients showed Na (304 μg/G), K (267 μg/G), Mg (92 μg/G) and Ca (12 μg/G). Among micronutrients Fe (92 μg/G), Cr (92 μg/G), Ni (48 μg/G), Co (38 μg/G), Cu (23 μg/G, Mn (12 μg/G) and Zn (15.22 μg/G) were found. Phenolic compounds were detected in the extracts and were found maximum (8.12 mg gallic acid/G extract) in 50% extract. Lower concentrations (6.25%, 3.25%) of the extracts significantly improved seed germination (%), germination index, shoot length, shoot fresh weight, shoot dry weight, root fresh weight, root dry weight and root area of wheat plants (p
