Spatial analysis of incidence of plant parasitic nematodes in rice-wheat-legumes cropping systems of Uttar Pradesh, India

摘要

Geographic information system (GIS) is one of the most powerful tools, now widely used, to understand various agricultural problems. Use of GIS in plant parasitic nematode research is a new field of activity and database creation in GIS environment and their analysis on the nematode-plant relationship are scanty. The main objective of this paper is to map the incidence and distribution of nematodes using GIS and to see their presence in different cropping systems. A case study from Uttar Pradesh in India is presented here as an example of GIS application in nematode research.
