Abstract

The experiment was conducted at Jimma University College of Agricultures and Veterinary Medicine (JUCAVM) under field condition to determine the effects of different weeding time of Ryegrass on growth and yield components of Wheat (Triticum spp.) The experimental design used was randomized complete block design (RCBD) and each of the experimental treatment was replicated three times. A Wheat cultivar, Digalu was grown with Ryegrass and different weeding time of Ryegrass T1 (weeding 15-45 DAS), T2 (weeding 30-60 DAS), T3 (weeding 45-75 DAS), T4 (weed free) and T5 (no weeding) were used as a treatment. Data were recorded on Wheat Plant height, Stem thickness, Number of tillers; Spike length and Spike number. The result revealed that various weeding time of Ryegrass statistically (p≤0.05) affected Plant height, Stem thickness, Number of tillers; Spike length and Spike number. The maximum values of all the parameters were recorded in the (15-45 DAS) except for Plant height and Stem thickness. Whereas, the minimum values of these parameters were recorded from (45-75 DAS) except for Plant height. It is advisable for growers to remove the Ryegrass before the critical weed-crop competition period which is most probably (15-45 DAS) to keep the crop weed free at this period.

Highlights

Wheat (Triticum spp.) is a cereal grain, originally from the Levant region of the Near East but cultivated worldwide (Peter, 2009) [12]
Most of the wheat grown in Ethiopia is bread Wheat, there is some durum wheat which is often grown mixed with bread Wheat
Data was collected from five central rows of each plot using the following parameters: Plant height, Stem thickness, Number of tillers, Spike length and Spike number every week fifteen days after planting

Summary

Introduction

Wheat (Triticum spp.) is a cereal grain, originally from the Levant region of the Near East but cultivated worldwide (Peter, 2009) [12]. In 2013, world production of Wheat was 713 million tons, making it the third most-produced cereal after maize (1,016 million tons) and rice Million tons) (FAO Stat, 2015) [4].Average yield of wheat in Ethiopia(1.3 t/ha) Hailu (2003), [7]. Is very low compared to New Zealand, Netherlands, Ecuador and France (8.9, 8.6, 8.0 and 7.6 t/ha) (FAO, 2013) [5].Ethiopia is the second largest wheat producer in sub-Saharan Africa, after South Africa. Wheat is among the most important crops in Ethiopia, ranking fourth in total cereals production next to Maize, Sorghum and Teff (CSA, 2009) [2]. Unchecked weed growth reduces crop yield up to 57% (Singh et al.,1997) [16].Weed infestation may reduce yield by 45.5 to 63.9% (Reddy and Reddi, 2002) [14], in Wheat while reduced up to 92% by competition from Ryegrass (Dickson et al, 2011) [3]
