YIELD ASSESSMENT AND ECO-FRIENDLY MANAGEMENT APPROACHES AGAINST TURCICUM LEAF BLIGHT (EXSEROHILUM TURCICUM) OF MAIZE IN MID-HILL CONDITIONS OF MEGHALAYAL. Sanajaoba Singh, Ram Dutta2 and A. Ratankumar Singh
The investigation was carried out to find out the yield assessment and eco-friendly management against turcicum leaf blight (Exserohilum turcicum) of maize in mid-hill conditions of Meghalaya. The yield loss was observed to the tune of 28.17 %. The per cent losses in parameters such as test weight (g), cob length (cm) and number of cobs/plant observed were 43.45, 36.00 and 34.09 % respectively. Area under disease progress curve and apparent infection rate was estimates from set of six observations. Results showed least PDI (18.44), least AUDPC (33.33) and least (0.05) r value from plots sprayed with Mancozeb 75% WP @ 2.5 g l-1. There was no significant difference between yield attributes such as number of plants per plots and number of cobs per plant. Maximum 100 seeds weight was recorded from plots sprayed with Mancozeb 75% WP @ 2.5 g l-1. Maximum cob length was recorded from plots sprayed with K2HPO4 @ 17.4 g l1+ZnSO4 @ 10g l1 (13.37) followed by Mancozeb 75% WP @ 2.5 g l-1(12.96 cm).
