Abstract

Among the biotic factors, weeds caused significant effects on the yield of roselle and play the greatest role in the production system. With this in mind, the study was carried out at Wondo Genet Rift Valley of Ethiopia to determine the critical weed competition period for growth, yield, and yield components of roselle under rainfed conditions. The experimental treatments consisted of a quantitative series of both the increasing duration of weedy periods and the length of the weed-free periods using Randomized Complete Block Design (RCBD) with three replications. Data of growth and yield-related parameters were timely collected following their respective standard methods and procedures and further subjected to analysis of variance (ANOVA) using SAS computer software version 9.4. The results analyzed showed that the weed competition duration had a significant influence on the number of primary branches per plant, the number of capsules /plants, fresh and dry calyx yield/plant, thousand seed weight, and seed yield kg ha-1. The highest fresh and dry calyx yield was recorded from the weed-free check (15348.60kg ha-1) and (1389.42 kg ha-1) whereas the lowest was from the weedy-check (1009.70 kg ha-1) and weedy for 75DACE (Days After Crop Emergence) (242.57 kg ha-1), respectively. The highest seed yield was recorded from the weed-free check (39.03 kg ha-1) whereas the lowest was from the weedy check (4.76 kg ha-1). The yield losses of roselle were estimated based on fresh and dry calyx yield. Thus, the highest yield loss of fresh and dry calyx yield was recorded in the weedy-check (93.42%) and weedy for 90 (82.54%) DACE whereas the lowest was in the weed-free check (0.00%), respectively. To determine the beginning and the end of the critical period of crop-weed competition 5 and 10% acceptable yield loss levels were used. Therefore, to reduce the yield losses by more than 10% and higher economic return, plants must be kept weeds-free within 60 to 90DACE to reduce the risk of economic yield losses as it is the critical period of weed-crop competition in roselle plants.
