Abstract
| The experiment was carried out to highlight the outcome of planting date on the emergence of aphids in different species of brassica at Agricultural College of Bahauddin Zakariya University Multan, Punjab (Pakistan) during 2014-2015 and 2015-2016. Four brassica species (B. carinata, B. rapa, B. napus and B. juncea) were seeded from October to November at different dates (Octo 20, Nov 05, Nov 20) in RCBD design (Randomized Complete Block Design) with standard cultivation procedures to detect the effect of sowing date on Brevicoryne brassicae population. Data were noted weekly and evaluated statistically. The ANOVA revealed highly significant effects of drill dates and species on Brevicoryne brassicae populations, while brassica species × sowing date interaction was also highly significant. Early sown crops bore fewer aphid populations in contrast to mid and late sown crops. Therefore, it may be concluded that mid-October can be recommended for the farming of brassica crops.
