A field experiment was conducted to detect the performance of maize and kale grown as pure stands and as intercrops.The experiment consisted of 33 treatments involving a number of intercrops and pure crops grown over a wide range of plant densities and three levels of nitrogen.
The study showed that the yield of the best intercrop(a combination of high plant density of maize with low plant density of kale)was 19% higher than the high— est yielding pure stand,when assessed in terms of the land equivalent ratio. The optimum plant density for the intercrop was higher than that of pure stands,which suggests that interspecific competition was less than intraspecific competition.
