Description A field experiment was conducted during kharif 2010 at Main Agricultural
Research Station, University of Agricultural Sciences, Dharwad, to study the effect of
strobilurin on growth, physiology and productivity in soybean using factorial
randomized block design with three replications. The experiment consisted of four
genotypes (JS-335, KHSb-2, DSb-1 and DSb-11) and three foliar applications of
strobilurin (150 g/ac, 175 g/ac and 200 g/ac) and a control. In all there were 16
treatment combinations.
Significant differences were observed in morphological, growth,
physiological, biochemical, yield and yield parameters with application of Strobilurin.
Among the treatments, strobilurin @ 200 g/ac exhibited superiority over rest of the
treatments, while giving a better response to most of the yield contributing characters
such as more number of branches, more number of nodes, more leaf area, more TDM,
higher percentage of drymatter partitioning into economically useful parts,higher
AGR,CGR,SLW, LAI, LAD, BMD, higher photosynthetic rate,higher chlorophyll
content, higher SOD activity, higher Ascorbic acidl content, higher Phenol content,
more NRA, and more protein, ultimately resulting into more number of pods per
plant, more number of seeds per pod , 100 seed weight and thus resulting in higher
seed yield.
Among the genotypes, DSb-11 gave highest seed yield (37.14 q/ha), followed
by JS-335 (35.22 q/ha) with application of strobilurin @ 200 g/ac compared to
control (30.73 q/ha). The application of strobilurin improved the morphological,
growth, physiological, biochemical and yield parameters. Irrespective of the
treatments the yield increase was to the tune of 12.50 per cent. Thus, it is inferred
from the above study that the foliar application of the fungicide strobilurin is quite
effective and can be used in increasing the seed yiend in soybean.
