    Differential responses of various amino acid based growth substances on physiological parameters, dry matter partitioning, productivity and quality of soybean (Glycine max (L.) merrill)
    (JNKVV, 2016) Sahu, Bhojendra; Samaiya, R.K.
    The present research experiment entitled “Differential responses of various amino acid based growth substances on physiological parameters, dry matter partitioning, productivity and quality of soybean (Glycine max (L.) Merrill)” was conducted during Kharif season of 2015- 16 at the Research Farm Adhartal, Department of plant Breeding and Genetics, JNKVV, Jabalpur (M.P). The research experiment was laid out in a Randomized block design with thirteen replications and two treatments comprised of soybean genotype JS- 97-52. Study of seedling vigour traits indicated that treated plants had maximum germination (79.77%) as compared to control plants (74.77%). Treated plants attained the maximum seedling length (2 5.02 cm) and seedling dry wt. (0.719 g) followed by control plants (22.16 cm) and (0.625 g). Treated plants possessed an average higher vigour index-I (3716.74) and vigour index-II (114.51). Minimum were recorded in control plants (1672.09) and (86.46). 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 (92.75) plants. Among growth analytical parameters the treated plants attained the maximum LAI at 90 DAS thereafter, it declined. Treated plants indicated an average higher LAI (5.24). Leaf area duration was found to be increased with advancement of crop age upto 75-90 DAS, afterwards it declined. Treated soybean crop with amino acid possessed an average higher LAD (9869.15cm2.days). RGR attained higher magnitudes in the very early growth span thereafter it declined. Treated with amino acid soybean had an average higher RGR (0.0586 g/g/day). CGR had higher magnitudes at 75-90 DAS followed by a decline pattern. Treated plants had an average higher (0.245 g/cm2/day) CGR. Quantification of various other physiological traits indicated that the treated soybean (45.61 %) showed the higher content chlorophyll index whereas; minimum chlorophyll content index was recorded in control plants (39.69 %). 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 higher 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%). Among morpho-physiological traits treated plants possessed the maximum plant height (51.52 cm) at matutity, maximum number of branches/plant (4.95), maximum number of nodules/plant (50.18), dry wt. of nodules (0.234 mg), effective nodes/plant (19.73) ,no. of pods/plant (46.33) and no. of seeds/plant (95.66). However, control soybean plants had the minimum plant height (47.99 cm) at matutity, minimum number of branches/plant (4.37), minimum number of nodules/plant (47.35), dry wt. of nodule (0.196 mg), effective nodes/plant (19.29), no. of pods/plant (40.87) and no. of seeds/plant (90.45). Among yield and yield components viz., treated plants registered the maximum seed yield (11.06 g/plant and 1317 kg/ha). Minimum was recorded in control plants (9.69 g/plant and 1274 kg/ha) of soybean variety JS-97-52. Seed treatment with amino acid in soybean produced maximum biological yield (23.37 g/plant and 3008.59 kg/ha). Treated plants (48.39%) and control plants (465.47%) were found to be associated with maximum and minimum harvest Index, respectively. A maximum magnitude of 100 grain weight was recorded in treated plants (7.70 g). The quantification of seed quality characteristics by biochemical estimations indicated variable response. Maximum protein content was registered in treated soybean (38.40%) followed by control plants (38.05%). Fat was found to be maximum in treated soybean (18.71%). Maximum fibre was noted in treated plants (4.13%) followed by control plants (3.94). Maximum carbohydrate was registered in treated soybean (28.27%) and minimum in control plants (28.03%). It is concluded from the study that seed treatment with amino acid (HYT ‘D’) @ 3ml/kg of seed improved the seedling quality, phonological events, morpho-physiological parameters, protein (%), fat (%), fibre (%) and carbohydrate (%) in soybean variety JS-97-52.
