Bio-stimulants are the substances which contain organic and inorganic compounds that stimulate plant growth and productivity. The present study was conducted to study the influence of different microbial stimulants, humic substance and amino acid mediated bio-stimulants on the morphological, physiological and yield traits of tomato. Treatment includes T1 - Control, T2 - Hyoroplus L (1.25 L ha-1), T3 - Heiko Root (3 capsules plant-1) localized in root zone, T4 - Heiko Root (3 capsules plant-1) drenched in root zone, T5 - Heiko Seed (750 g ha-1), T6 - Hyoroplus G (20 kg ha-1), T7 - Hyoro My+ (20 kg ha-1) and T8 - Viva (10 L ha-1). Bio-stimulant treatments were given as either soil or foliar application at different growth stages. Observations were recorded at three stages viz., 30 Days after Transplanting (DAT), 60 DAT and 90 DAT. Better performance was observed in bio-stimulants treated plants than the untreated plants. Significant increase in shoot length, root length, total chlorophyll content, soluble protein, nitrate Reductase activity and yield traits like number of fruits per plant, fruit weight and total fruit yield were observed in bio-stimulants treated plants. Among the treatments, morpho-physiological and yield traits of T7 - Hyoro My+ (20 kg ha-1) and T8 - Viva (10 L ha-1) applied tomato plants were markedly influenced. Bio-stimulants proved to be an effective tool to boost up the plant growth and productivity.
