ABSTRACT

Field experiments were carried out during kharif (wet season) and rabi (dry season) seasons of
1998 and 1999 to study the impact of multiple pest injuries on rice yields. Observations were
recorded on injuries due to different pests on 200 randomly selected hills over an area of 1ha at
weekly intervals starting from 15 DAT throughout the crop growth and hill-wise yield was recorded
at harvest. Regression analysis of the data based on extent of injuries due to major pests revealed
that there was significant reduction in yield due to per cent white ears by the stem borer while silver shoots produced due to gall midge infestation did not have significant effect. Though, the injuries due to rice tungro disease and rats were observed in limited number of hills, they also had adverse impact on rice yields.
