Abstract: The experiment to study the effect of biostimulants and growth regulators on herbage and quality in coriander var CO (CR) 4 was conducted at College Orchard, Department of Spices and Plantation Crops, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore (Tamil nadu), India during 2015- 2016. The objective of the this study is to find out the influence of bio-stimulants and growth regulators (Panchagavya @ 3 per cent, Vermiwash @ 3 per cent, Moringa leaf extract @ 3 per cent, PPFM @ 1 per cent, Cytozyme @ 1000 ppm, Tricontanol @ 5ppm, Humic acid @ 1000 ppm and Brassinosteroid @ 0.5 ppm) on plant growth, physiological parameters, yield, quality and cost economics of leafy coriander var CO (CR) 4. The experiment was laid out in a randomized block design with nine treatments replicated thrice and data was recorded during 2015 - 2016 and mean data presented Among the different treatments, foliar application of 1 per cent PPFM (T4) recorded the maximum plant height of 46.26 cm while growth parameters like average number of primary branches (10.41) and number of leaves (41.90) were highest in foliar application of humic acid @ 1000 ppm (T7). The physiological parameters viz., leaf area (41.79 cm2), total chlorophyll (2.74 mg g-1) and nitrate reductase activity (348.28 µg of No2 g ha -1) were found to be highest in 1000 ppm humic acid. Humic acid @ 1000 ppm enhanced the physiological and biochemical parameters and resulted in higher cumulative herbage yield of 4679.73kg ha -1 The quality parameters like leaf ascorbic acid (141.71 g 100 g -1) and leaf protein (2.81 g 100 g -1) were highest in the humic acid @ 1000 ppm. The higest benefit cost ratio (3.0) was registered in foliar application of humic acid @ 1000 ppm (T7) compared to other treatments.
