Management of Striga (Striga hermonthica) in Sorghum (Sorghum bicolor) at Jeldu District

Abstract

Afield experiment was conducted from 2017 to 2018 to evaluate herbicides which can best perform against Striga in sorghum fields of Jeldu district West Shoa Zone. The experiment was carried out in randomized complete block design with three replications. Data was collected on crop and weed related parameters. Result obtained indicted that, Sorghum plant height, stock biomass, grain yield and thousand seed weight showed significant (P<0.05) difference due to treatments. The highest mean plant height (240.92 cm), Stock biomass (13967 kg/ha), grain yield (886.2 kg/ha) and thousand seed weight (24.3 gram) were recorded from the sequential application of Dual gold+ 2, 4-D as compared to weedy check. The lowest Striga height (31.917 cm) was recorded from sequential application of Dual gold+ 2, 4-D. Similarly, the lowest Striga biomass was recorded from farmers practice followed by Kerosene (for seed dressing) and sequential application of Dual gold+ 2, 4-D. Therefore, sequential application of Dual gold+ 2, 4-D was found effective against Striga weed in sorghum. hence, sequential application of Dual gold+ 2, 4-D can be recommended as one component of integrated Striga management in sorghum field.
