The response of morphological characteristics of some Soybean Varieties (Glycine max (L.) Merill) a vegetative phase in waterlogging condition

Indonesia's microclimate change issues base the big impending for inundation to happen when precipitation is too extraordinary in area of soybean farming, which can give an influence production. Inundation a major difficulty many parts entire world and soybeans are delicate inundation. The use plant growth regulators (PGR) respond alteration stresses. This research was conducted from June September 2020 irrigated rice fields Kwala Sememe Deli Tua, Serdang District, using Randomized Block Design (RBD) one factor consisting Anjasmoro, Grobongan, Deja 1, Devon 1 varieties with 96 h inundation, application PGR GA3 Salicylic Acid. parameters observed were height, number leaves, adventitious roots. results showed that had effect on cultivar used. Anjasmoro best response height variables while Grobogan opposite response.
