Effect of Organic Nutrients and Growth Regulators on Yield and Quality of Goldenrod (Solidago canadensis L)

An Investigation was conducted to study the effect of organic inputs and growth regulators on yield and quality of goldenrod (Solidago canadensis) was conducted at the floricultural unit, Department of Horticulture, Faculty of Agriculture, Annamalai University during 2018. The experiment was laid out in randomized block design with twelve treatments, various organic inputs and growth regulators including panchagavya @ 3%, vermiwash 1:5 dilutions, humic acid @ 0.2%, GA3 @ 250 ppm, NAA @ 250 ppm were applied. The yield and quality characters were studied at different stages. The observations recorded viz., yield of flower stalks/ha, days to first flowering, length of flower stalks and weight of individual flower stalks. The results revealed that plants treated with NAA @ 250 ppm + panchagavya @ 3% (T9) was observed highest flower stalk yield (1140.02 flower stalks/ha), No. of flower stalks/plant (24.48), weight of individual flower stalks, days to first flowering. Considering the overall performance, it was found that the plants treated with NAA @ 250ppm + Panchagavya @ 3% recorded better performance with regard to growth, yield and quality characters.
