Lindeman on Onion, Allium cepa Linnaeus” were carried out at Research
farm, College of Agriculture, (SKRAU), Bikaner during Rabi, 2015-16. The
minimum incidence of thrips (30.55thrips/plant) were observed on early
transplanted crop on (24th November) and highest bulb yield was obtained
from crop transplanted on 4th December (184.75 q ha-1). The maximum
incidence of thrips (44.35 thrips/plant) and minimum bulb yield (173.50 q ha-1)
were recorded in late transplanted crop i.e. 3rd January. A significant positive
correlation was observed between transplanting times and thrips population
whereas, negative in both transplanting times and thrips incidence with bulb
yield of onion.
