Online published on 20 July, 2019. Abstract The field trials were conducted during 2015–2017, to determined individual and additive effect of two fungicides viz. Propiconazole and Carbendazim 12% and Manzozeb 63%, three bioagents viz. Trichoderma viride, T. harzianum & T. virens) and one organic manure i.e. neem cake on the growth, yield, leaf and rhizome pigments of turmeric against Colletotrichum gloeosporiodes causing leaf spot disease. Among all the foliar treatments, significant result (P 0.05) was recorded with propiconazole + Trichoderma viride + neem cake with growth parameters viz., plant height and rhizome girth (81.03 cm & 19.87 cm) and yield viz. fresh rhizome weight kg/plot and dry rhizome weight kg/plot (4.18 & 2.27) and chlorophyll 26.67mg/g of fresh leaf, carotenoid 0.850 mg/g of fresh leaf and % of curcumin 0.158 mg/g of fresh rhizome and with lower leaf spot incidence. The average of disease severity (17.65) over control (29.30). Neem cake gave least significant result at same parameters over the control. The results showed the significant increase in growth and yield with reduction of both leaf spot severity and incidence of turmeric over the control.
