Allelopathic Effects of Sunflower on Some Operative Components of Cotton
Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 24
Abstract
In order to investigate the allopathic effects of sunflower on cotton germination, this research was done in the form of a quite accidental plan with 3 replications. The density of the extracts involved 3 levels for sunflower (50, 100 and 150%) and also the control treatment (0%). The sunflower extract showed a lot of preventing effects on germination and growth of cotton plant. The statistical comparisons showed that as the density of the extract increases, the number of leaves, the number of subshrubs, the size of the shrubs, the number of flowers and the yarns weight has a significant decrease in comparison with control. The most amount of decrease among all the measured parameters was that of 150 mg/l density.
