Abstract: Field experiment was conducted at the Research Farm of the Department of Crop Production and Horticulture, Modibbo Adama University of Technology, Yola during 2010 and 2011 raining seasons to study rates of propanil for weed control in rice (Oriza sativa (L.)) at Yola Northern Guinea Savanna of Nigeria. The experimental design used was split plot. The treatments were five propanil rates (0 kg a. i. /ha, 2 kg a. i. /ha, 4 kg a. i. /ha, 6 kg a. i. /ha and 8 kg a. i. /ha) assigned to sub plots and were replicated four times. Data collected were establishment count, crop vigour, plant height, weed count, weed dry weight, number of productive tillers, number of grains per panicle, grain yield (kg/ha) and 1000-grains weight. The data collected was subjected to analysis of variance (ANOVA) appropriate to split plot design as described by Gomez and Gomez (1984). Means were separated using least significance difference (LSD) at 5% probability level. The result revealed that all the parameters measured (establishment count, crop vigour, plant height, wed count, weed cover, wed dry weight, number of productive tillers, number of grains per panicle, 1000-grains weight and yield (kg/ha)) were significantly affected. Effect of propanil rates on establishment count, crop vigour, plant height, at 30 DAS, weed count and weed dry weight revealed that 0 kg a. i. /ha proved the best while yield parameters measured revealed that 4 kg a. i. /ha proved the best in two years raining season followed by 6 kg a. i. /ha. Effect of propanil rates on yield parameters revealed that propanil rate of 4 kg a. i. /ha proved the best. Based on the result obtained, it can be concluded that propanil rate of 4 kg a. i. /ha should be adopted in rice fields in Yola and its surrounding environs within the same ecological zone.
Keywords: Evaluation, rates of propanil, and weed control.
