A field experiment on hybrid maize was carried out at the Research field of Bangladesh Agricultural Research Institute, Joydebpur, RARS Jamalpur and Jessore during rabi season of 2012-13 to evaluate leaf clipping effect on grain and fodder yield of hybrid maize. Six treatments namely; T1 = no leaf clipping (control), T2 = all leaves clipping above cob, T3 = all leaves clipping below cob, T4 = T2 + stem clipping above cob, T5 = all leaves clipping, T6 = keeping only ear leaf but other leaves clipping were used as treatments variable in the present study. Leaves clipping were done at 20 days after silking. Leaf clipping provided a remarkable amount of fodder yield but it reduced total dry matter production as well as cob dry weight which ultimately reduced grain yield. In all the locations, the highest grain yields (11.66, 10.15 and 10.75 t ha-1) were recorded in no leaf clipping treatment (control) while the lowest (5.59, 5.22 and 4.90 t ha-1) in all leaves clipping treatment. Over the locations, the highest fodder yields (10.71, 9.95 and 9.07 t ha-1) were recorded in all leaves clipping treatment but it reduced grain yield drastically (49 to 54%). The lowest fodder yields (3.47, 4.40 and 5.06 t ha-1) were recorded in all leaves clipping above cob treatment. Grain yields were less affected (6.09 to 14.28 % reduction) by all leaves clipping below cob treatment, which provided about 6 ton fodders ha-1 in addition to grain yield. Therefore, all leaves clipping below cob at 20 days after silking would be an option for the farmers who usually practice leaf clipping in maize for fodder purpose.

Key words: Leaf clipping, fodder yield and grain yield.
