Type: article
Abstract: An experiment was conducted to evaluate the effect of biostimulants under different application methods in grow bag cultivation of organic amaranthus. Foliar application and wick fertigation were the two methods of application under the study for which wick fertigation were installed using pvc pipes and glass wool wicks were used. Biostimulants such as humic acid (3%), humic acid fulvic acid mixture (3%), moringa leaf extract (3%), vermiwash (3%), cow urine (ten times diluted), salicylic acid (50 mgL-1) were compared with RDF (0.22:0.11:0.11 g/plant) and distilled water (control) at weekly intervals. Observations were recorded on different biometric characters viz. plant height (cm), leaves per plant, leaf length (cm), leaf width (cm), stem girth (cm), branches per plant, root length (cm), days to flowering, leaf/stem ratio, fresh weight of leaves per plant (g), yield per cutting (g) and yield per plant (g). Among the biostimulants, humic – fulvic acid mixture @ 3% produced the highest plant height (85.83 cm), leaf length (15.08 cm), leaf width, branches per plant, fresh weight of leaves (225.85 g) and yield per plant (646.01g).
