Effect of population density of Phalaris minor on production potential of wheat (Triticum aestivum)
Year: 2001
Type: article
Abstract: A field experiment was conducted at Ludhiana, Punjab, for two years (2006-07 and 2007-08) to study the ef- fect of varying population levels viz., 0, 10, 15, 25, 50, 75, 100, 125, 150, 200, 250 and a solid stand of Phalaris minor on the production potential of wheat ( Triticum aestivum L. emend Fiori and Paol) crop and also to find out the critical threshold level of Phalaris minor. In the experiment Phalaris minor population was deliberately main- tained in wheat crop after 30 days of sowing. As the population density of Phalaris minor increased, the dry mat- ter production, number of tillers as well as effective tillers and ultimately yield of wheat decreased exponentially. Even the presence of 15 plants/m2 Phalaris minor resulted in significant decrease (14%) in wheat yield. Reduc- tion in wheat yield was mainly attributed to reduction in the number of effective tillers, lesser grains/spike and lower 1,000-grain weight.
