Abstract:
A field experiment was planned and conducted during 2021-22 at Horticulture Research Block, School of Agriculture Sciences, SGRR University, Dehradun, Uttarakhand to investigate the “Effect of various organic growing media on growth and yield of Gaillardia (Gaillardia pulchella Foug) at Dehradun valley of Uttarakhand”. The experiment was laid out in randomized block design with three replications and ten treatments. The treatments comprised following levels of different growing media with different concentrations viz. T₁ (Control), T₂ (vermicompost + soil @3:1), T₃ (FYM + soil @3:1), T₄ (cocopeat + soil @3:1), T₅ (leave manure + soil @3:1) T₆ (cow urine + soil @20%:1), T₇ (Vermicompost + Farmyard Manure + Cocopeat + Soil @1:1:1:1), T₈ (Vermicompost + Farmyard Manure + Cow Urine + Soil @1:1:20%:1) and T₉ (Vermicompost + FYM + leave manure + soil @1:1:1:1) and T₁₀ (Vermicompost + Farmyard Manure + Cocopeat + Cow Urine + Leaf Manure + Soil @1:1:1:20%:1:1). The observations on various attributes viz. growth and yield were recorded at different harvest intervals. The results showed that treatment T₂ (Soil + vermicompost @3:1) found to be most effective in terms of growth characters such as Plant height (33.35cm), Leaf Length (14.59cm), Leaf Width (4.39cm), Stem diameter (2.21cm), Plant spread N-S (35.86cm) and W-E (41.62cm). The maximum flower yield (0.574 kg/plot) and (57.4q/ha^-1) was noted in the treatment T_10.
