Effect of bioagent and seed coating on seed quality parameters in soybean (Glycine max (L.) Merrill.)

Seed coating especially film coating, is one such technique which has gained commercial importance owning to its practical utility as an effective delivery system as seed protectant and fortifying chemicals which maintain good germinability and vigour in field as well as laboratory viz.,strong seedlings grow faster than less vigorous ones, are more tolerant to adverse conditions in the seedbed and are better to resist diseases. Seeds of soybean cv. JS-335 were coated with polymer ((DISCO AG SP RED L-200), protectant (thiram and carboxin), bioagent (Mycorrhiza) and polymer untreated seeds as control. It was observed that, irrespective of the treatments, the seed quality parameters declined progressively with the increase in storage period (12 months). Under field conditions, higher vigour (2348) was noticed in seed treated with polymer (DISCO AG SP RED L-200) + Thiram + Quick roots **/ Mycorrhiza and lower vigour was seen inno polymer treatment or water + thiram. The field emergence (%) revealed that all the three polymer seed coating treatments were on par at 30 DAS (78.07 %, 77.19 % and 77.19 %) and 50 DAS (80.99 %, 80.11 % and 79.56 %) when compared to control treatment i.e., no polymer treatment or water + thiram at 30 DAS (71.68 %) and 50 DAS (71.30 %), respectively. Among the yield attributes, significant difference was observed in seed yield/plant with treatment polymer (DISCO AG SP RED L-200) + Thiram + Quick roots **/ mycorrhiza registering highest (22.20 g) yield, while the lowest (18.40 g) yield was observed in polymer untreated or water + thiram.

An investigation on effect of seed coating on seed quality and yield of soybean [Glycine max (L).Merrill] was conducted during Kharif 2018 at Instructional Farm, Department of Agriculture Botany, Vasantrao Naik Marathwada Agriculture University, Parbhani. The experiment was laid out inRandomized BlockDesign with three replications and seven treatments viz., T1-Untreated seeds,T2-Polymer coating, T3-T2+Vitavax, T4-T3+GA3 100ppm, T5-T3+CCC 100ppm, T6-T3+, NAA 50ppm, T7- T3+IAA 50ppm. The experiment was conducted to study effect of different seed coating treatments such as seed on quality and yield of soybean. From the present investigation it was observed that T4 (T3+GA3) 100ppm followed by T6- (T3+, NAA50ppm) and T7 - (T3+IAA) 50ppm, recorded higher seed quality and yield contributing traits. Mean days for 50 per cent flowering and mean days to harvest found non-significant. Treatment T4- (T3+GA3 100ppm) found superior in increasing plant height over treatment T5- (T3+CCC100ppm).In treatment T4-(T3+GA3) 100ppm was found superior for number of branches, leaf area content, chlorophyll content, number of pods per plant, number of seed per pod. Yield per plot and per ha., test weight, harvest index followed by treatments T6- (T3+NAA50ppm) and T7-(T3+IAA 50ppm than all other seed coating treatments over the control. Biochemical studies found that, oil content and protein content higher in T7-(T3+IAA50ppm) followed by treatments T6-(T3+,NAA50ppm) and T5-(T3+CCC100ppm) than all other coating treatments over the control. Seed germination (%), seed moisture (%), plant total dry weight, was significantly in treatment T4- (T3 + GA3100ppm) followed by treatments T6-(T3+ NAA50ppm) and T7-(T3+IAA50ppm) than all other seed coating treatments over the untreated seed.

Diaporthe seed decay can compromise seed quality in soybean [Glycine max (L.) Merr.] in the warm and humid production areas of the United States during crop maturation. In the current study, 45 isolates of Diaporthe were recovered from seed sampled from soybean fields affected by Diaporthe-associated diseases in eight U.S. states in 2017. The isolates obtained belonged to 10 species of Diaporthe based on morphology and phylogenetic analyses of the internal transcribed spacer, the partial translation elongation factor 1-alpha, and beta-tubulin gene sequences. The associated species included D. aspalathi, D. caulivora, D. kongii, D. longicolla, D. sojae, D. ueckerae, D. unshiuensis and three novel fungi, D. bacilloides, D. flavescens and D. insulistroma. One isolate each of the 10 species was examined for pathogenicity on seed of cv. ‘Sava’ under controlled conditions. Seven days post-inoculation, significant differences in the percentages of decayed seeds and seedling necrosis were observed among the isolates and the non-inoculated control (p<0.0001). While the isolates of D. bacilloides, D. longicolla, and D. ueckerae caused significantly greater percentage of decayed seeds (p<0.0001), the isolate of D. aspalathi caused the greatest seedling necrosis (p<0.0001) when compared to the non-inoculated control. The observation of new fungi causing Diaporthe seed decay suggests the need for a more comprehensive survey in the U.S. soybean producing areas since members of the genus Diaporthe appear to form a complex that causes seed decay.
