Weed Communities Responses to Different Fertilizer Managements in Summer Maize Field
Journal Title: Scholars Journal of Agriculture and Veterinary Sciences - Year 2017, Vol 4, Issue 5
Abstract
The impacts of long-term diverse fertilizer managements on weed species and communities were studied in experimental plots of irrigated field established in 1990 at Wuquan village, Yangling, China. This study was demonstrated that the randomized complete block design with 5 replications in summer maize season. Effects of diverse fertilizer managements on crop and weed growth, thus on influences of farmland biological diversity. Treatment without N or P, affects not only weeds species but also weed diversity indices. N fertilization could influence the species richness and diversity, also dominant the weed population size and consequently it could change the level of community evenness. P fertilizer application would change the presence of weed species in the field reasonable balanced fertilization (NPK) treatment can control species types and maintaining the role of farmland ecosystem biodiversity.
