In India, phytonematodes are reported to cause about 10-40 %yield loss in sugarcane.In India, Uttar Pradesh is the major sugarcane growing state, contributing about 48% of the area and gymnastics wall decals 40% of the production.The present study was undertaken to record biodiversity, to correlate the soil major edaphic factors (temperature & moisture).
The study was also centered on to reveal the edaphic factors affecting sex ratio fluctuation of the dominant phytonematodes.Soil temperature, which changes constantly, is a major factor influencing nematode development.Temperature is an important environmental factor for organisms.
Different organisms have their own optimal temperatures for normal deus gorras activities and high and low temperature limits they can tolerate.Diurnal fluctuations in temperature vary in extent and depend upon soil type, texture, moisture, atmospheric conditions, latitude, elevation, season and soil cover.Cool climate species often develop slowly in winter and become more active when temperatures rise in spring season and in this season plant parasitic nematodes population decrease.
Moisture plays an important role in the movement of the soil organism.The findings indicated that during winter period when moisture and humidity is high in soil environment conditions.Populations of plant parasitic nematodes were highest in this season.
