Main Article Content
Abstract
In present study field experiments were conducted at the Research Farm Adhartal, Department of Plant Breeding and Genetics, JNKVV, Jabalpur (M.P.) during Kharif season of 2015-2016. The research experiment was laid out in a Randomized block design with thirteen replications and two treatments i.e T1- control (untreated) and, T2-Treated amino acid complex T2-Treated amino acid complex @3ml/kg seed (seed coating with 5-7ml water) comprised of soybean genotype JS 97-52. Five plants were randomly selected from each treatment and replications for Phenological and Physiological Parameters. The phenological observation showed the impact of amino acid seed treatment on various phenophasic developments. Treated plants (37.00 days) took shortest time for flower initiation whereas control plants had the late appearance of flower initiation (46.92 days) in soybean plants. Treated plants (53.61 days) took shortest time for 50% flowering whereas control plants had the late appearance of 50% flowering (56.38 days) in plants. Control (50.92) took higher days to pod formation, whereas treated plants (48.92) took the minimum time to pod formation. Days to maturity was also varied significantly for soybean. Maximum and minimum value was recorded in control (97.77) and treated plants (92.75).Maximum photosynthetic rate was recorded in treated plants (18.37 μmol/m2/s) followed by control plants (17.74 μmol/m2/s), water use efficiency in treated soybean plants (24.54 μmol/mmol) was measured followed by control plants (23.54 μ mol/mmol), stomatal conductance was recorded higher in treated plants (0.749 mol/m2/s) followed by control plants (0.713 mol/m2/s). Transpiration rate was recorded lower in treated soybean (6.56mmol/m2/s) as against control (7.07mmol/m2/s) and relative water content was recorded maximum in treated plants (74.23%) followed by control soybean plants (70.31%).
