Effect of Long-term Fertilizations on Composition of Weed Communities in Maize Field
Year: 2005
Type: article
Abstract: Plot trials were carried out to study effects of different patterns of long-term fertilization on composition of weed communities in maize field. The results show that no significant difference was observed in composition of weed communities between plots receiving balanced NPK fertilization of organic manure or chemical fertilizer. In plots without P application changes in composition of weed communities were obvious and so was the case in plots without N application, though not so obvious as it was with the former. In plots without K application, however, composition of the weed communities remained almost unchanged. PCA analysis indicated that soil available P was the most important factor affecting composition of weed communities, and followed by soil available N.
