Evaluation Of Weed Control Methods For Sweetpotato Production On An Ultisol Infested With Panicum Maximum And Mimosa Species
ABSTRACT
Field experiments were conducted at the eastern farm of the Michael
University of Agriculture, Umudike and in a farm at Uyo central in 2007 rainy
evaluate the effect of sweetpotatO varieties and different weed control methods
c density, weed dry weight, crop leaf area index, photosyntheticallY active
radiatio tuber yield. The study was established as a split-plot treatment with
swectpotatO varic (T1S86/0356, T1S87/0087, Ex-lgbariam and OP/TI S2532. 1. SP.
13), as main p treatments. The subplot treatments comprised six weed control
methods: three rates Primextra(at 1 .3 kg a.i had , 1 .98 kg a.i ha ,and 2.64
kg a.i had ), manual weeding carrR out once and twice, and an untreated
control. Results obtained indicate that seetpotal varieties and weed control
methods had significant influence on weed density and dr• matter. In Umudike,
OP/T1S2532.I.SP. 13 followed by TI S87/0087 significantly reduced total weed
density better than other varieties. In Uyo, lowest total weed density was
obtained from plots planted to Ex-lgbariam, though not significant when
compared with other varieties. In Umudike, Primextra at 2.64 kg a. i ha', and
1.98kg a i ha',followed by plots weeded twice controlled weeds better than the
other treatments
