Abstract:

A field experiment was conducted in the wet season of 2015 to study the effect of some weed control methods on the performance of upland rice at Kafanchan, Kaduna State, in the Southern Guinea Savanna of Nigeria. There were eight treatments as follows: 1) 3.0 kg ai/ha glyphosate followed by 3.0 kg ai/ha propanil +0.6 kg ai/ha trichlopir, 2) 3.0 kg ai/ha propanil + 1.6 kg ai/ha 2,4-D at 3 weeks after sowing (WAS), 3) 3.0 kg ai/ha propanil + 1.6 kg ai/ha 2,4-D at 3 and 6 WAS, 4) 3.0 kg ai/ha propanil + 0.6 kg ai/ha trichlopir at 3 WAS, 5) 3.0 kg ai/ha propoanil + 0.6 kg ai/ha trichlopir at 3 and 6 WAS, 6) hoe weeding at 3 and 6 WAS, 7) hoe weeding at 3, 6, and 9 WAS and 8) a weedy check. The treatments were laid out in a randomized complete block design (RCBD) and replicated three times. Grasses especially Cynodon dactylon (L) Pers, Dactyloctenium aegyptium (L) Wild, Digitaria ciliaris (Retz.) Koel, Echinochloa colona (L) Link, Ischaemum rugosum Salisb and Panicum repens L constituted 73% of weed infestation in the study area. Sedges (Fimbristylis miliacea (L) Vahl, Fimbristylis dichotoma (L) Vahl, Cyperus rotundus L and Cyperus iria L constituted 18% while the broad leaves Polygonum hydropiper L and Alternanthera sessilis (L.) R. Br. ex DC constituted 9% of weed infestation. All the herbicides were similar in their effects on the grain yield and were comparable with the hoe weeding treatments and significantly higher than the weedy check. There is, however, the need for gross margin and cost-benefit analysis to determine the profitability of each of the weed control treatments.
