Effect of seed enhancement treatment using leaf extract on physiological and morphological characteristics of green Gram (Vigna Radiate L.) seed adt 3

Green gram (Vigna radiate L.) is also known as mung bean or golden bean belongs to the Family Leguminosae. Green gram is a short duration crop and mainly cultivated as a rainfed crop under Rice fallow condition and irrigated crop. The low productivity under rainfed condition is due to soil moisture deficit, uneven rainfall, low soil fertility and poor crop management. To overcome this problem, seed researchers like Henckel as early as 1964 recommended the seed hardening techniques to alleviate the moisture stress condition. The present study will emphasize on the effect of seed hardening using various leaf extract like prosopis, pungam, nochi, neem,umathai, aduthoda, nerium, papaya, bittergourd etc. on seed and seedling characteristics like germination per cent, speed of germination, accumulated speed of germination, mean daily germination, root length, shoot length, seedling length, DMP, SV-I and SV-II of green gram ADT3. From the present study, it could be concluded that green gram seeds should be hardened with 1% prosopis leaf extract for 3 hours @ 1/3 rd volume of solution to enhance the seed and seedling quality characteristics under adverse environment conditions. In addition, green gram seeds may also be hardened with 1% pungam leaf extract to get the similar results.
