Intervarietal competition in yield trials with cotton
Published online by Cambridge University Press: 27 March 2009
Extract
The effect which different varieties grown on small plots side by side may have upon each other is usually termed competition. Naturally if a tall variety, or one having a root system highly developed, is planted on small plots in alternation with a short variety or one with small roots, it is to be expected that the latter will suffer from the unfavourable neighbourhood, whereas the former will be benefited. In other words, when testing varieties differing in their habits of growth, etc., owing to the effect of competition some of them may appear better and others worse than they are under natural conditions.
