The impact of insect pollinators on the yield of two canola varieties (‘Ganyou’ in which pollen viability and germination are adversely affected by soil salinity, and ‘Oscar’ that is more tolerant of soil salinity) was studied at the Research Farm of the Khyber Pakhtunkhwa Agricultural University, Peshawar, Pakistan in 2009 and 2010. Yields were similar between the two cultivars. Significant differences were observed between pollinated and covered plants for three yield parameters (i.e., total yield, number of seeds per sliquae, and weight of 100 seeds). Average yields were 189.3 ± 1.7 pods/plant in the pollinated plots and 142.2 ± 2.4 pods/plant in the covered plots. There was an average of 15.0 ± 0.9 seeds/siliquae in pollinated plots and 11.0 ± 0.8 seeds/siliquae in covered plots. The weight of 100 seeds was 0.55 ± 0.02 g in pollinated plots and 0.37 ± 0.01 g in covered plots.
