Abstract: The present investigation on the "Effect of bioregulators and FeSo 4 on growth, yield and quality of crossandra (Crossandra infundibuliformis L.)" was carried out in the Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalainagar during 2011-2013 in RBD with fourteen treatments and three replications.Fourteen treatment combinations were formed by foliar application of bioregulators viz., triacontanol (10 and 20ppm), brassinosteroid (0.5 and 1.0 ppm), maleic hydrazide (500 ppm and 1000 ppm) and FeSo 4 (0.5%), individually and in combination with FeSo 4 0.5% on 3 rd , 6 th and 12 th MAP.The control was maintained with water spray.The biometric observations like plant height, stem girth, number of branches and leaves per plant, plant spread, leaf area, chlorophyll content, dry matter production, number of spikes per plant, spike length, number of flowers per spike, individual flower length, ten flowers weight, carotenoid and xanthophylls content, visual scoring, flower yield per plant and hectare and shelf life were recorded.The results revealed that the treatment combination of maleic hydrazide (MH) 500ppm+Ferrous sulphate 0.5% (T 8 ) was found to be the best in growth, yield and quality attributes followed by maleic hydrazide (MH) 500ppm (T 6 ).
