dc.description.abstractAbstract: A field experiment entitled “Alleviation of moisture stress in soybean (Glycine max L.) through exogenous application of gibberellic acid and potassium nitrate” was conducted at Integrated farming research unit , Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during Kharif season of 2018-19. The soil of experimental plot was clay in texture. Soil was slightly alkaline in reaction. As regards to fertility status, the soil was low in available Nitrogen (206.98 kg ha-1), available Phosphorus (16.32 kg ha-1), high in available Potassium (350.2 kg ha-1) and medium in organic carbon (0.57%). The experiment was laid out in Randomized Block Design (RBD) with ten treatments and replicated thrice. The treatment comprised of control (water spray), 15 ppm GA3 at flower initiation stage (T2), 30 ppm GA3 at flower initiation stage (T3), 1% KNO3 at flower initiation stage (T4), 15 ppm GA3 at pod formation stage (T5), 30 ppm GA3 at pod formation stage (T6), 1% KNO3 at pod formation stage (T7) ,15 ppm GA3 at flower initiation and pod formation stage (T8), 30 ppm GA3 at flower initiation and pod formation stage (T9) and 1% KNO3 at flower initiation and pod formation stage (T10). Growth characters viz.,number of branches, number of functional trifoliate leaves, leaf area,chlorophyll content, dry matter were found significantly maximum with treatment 30 ppm GA3 at flower initiation and pod formation stage. Yield attributes and yield viz., number of pods per plant, seed yield plant-1, seed index (g), protein yield (kg ha-1) and seed yield (kg ha-1) were recorded significantly superior in treatment 30 ppm GA3 at flower initiation and pod formation stage. Whereas, straw yield was higher in treatment of 30 ppm GA3 at flower initiation and pod formation stage. Maximum harvest index was observed in 15 ppm GA3 at flower initiation and pod formation stage. Total uptake of nitrogen, phosphorus and potassium was significantly maximum in 30 ppm GA3 at flower initiation and pod formation stage. Gross monetary returns were found significantly maximum in 30 ppm GA3 at flower initiation and pod formation stage. Net monetary returns were found significantly maximum in 15 ppm GA3 at flower initiation and pod formation stage. Maximum B:C ratio was observed in 15 ppm GA3 at flower initiation and pod formation stage.en_US
