Abstract: -To evaluate the effect of planting date and spatial pattern on common bean yield under weed-free and weed-infested conditions, an experiment was conducted in Kelachay, Northern Iran, in 2013. The experimental design was a randomized complete block in a factorial arrangement with three replicates. Factors were planting date (10 August and 20 August), spatial pattern (square and rectangular planting pattern, with a planting distance of 30 x 30 cm and 45 x 20 cm, respectively), and weed management regime (weed-f… Show more

“…In case of B:C ratio; the interaction of 30 cm x 10 cm (S 1 ) and Imazethapyr 35% WG + Imazamox 35% WG (Pre-mix) @ 40 g a.i./ha (W 4 ) achieved significantly maximum B:C ratio (4.52); while lowest was recorded under interaction of 45 cm x 6.5 cm (S 2 ) with weedy situation (W 6 ) (-0.16). Results were also confirmed by findings of Esmaeilzadeh and Aminpanah (2015), Kebede et al (2015) and Pulok et al (2015).…”

“…To achieve high yields in common bean crop, weed control is important because crop-weed competition can result in production losses ranging from 12 to 80% [223][224][225][226] and a deterioration in yield qualities too [227]. Not all weeds are equally perncious to yield; nevertheless, the broad-leaved weed species Amaranthus retroflexus L., Chenopodium album L. (Amaranthaceae), Portulaca oleracea L. (Portulacaceae), Datura stramonium L. (Solanaceae), Convolvulus arvensis L. (Convolvulaceae), the sedge species Cyperus esculentus L., Cyperus rotundus L. (Cyperaceae), and the grass weeds Cynodon dactylon (L.) Pers., Sorghum halepense (L.) Pers., Echinochloa crus-galli (L.) Beauv., Eleusine indica (L.) Gaertn., Setaria viridis (L.) P.…”

“…The reduction in grain yield due to weed interference throughout the cowpea cycle is quite variable in several studies, with values of 64% (Yadav et al, 2018), 66% (Gonzaga et al, 2018), 68% (Adigun et al, 2014) and up to 90% (Freitas et al, 2009). For phaseolus species, this same trend in reducing yield happens (Frenda et al, 2013;Esmaeilzadeh & Aminpanah, 2015;Odero & Wright, 2018). Therefore, the results of the present study show the importance of adjustments to local specificities, as the reduction in yield is dependent on several factors, such as weed community, cultivar, cultivation conditions and edaphoclimatic characteristics of each region.…”
