Abstract:
Under field conditions population of root-knot nematode, M. incognita juveniles were found throughout the year in the rhizosphere of pomegranate with varying degrees of occurrence. The population goes down during the summer months while in mid-winter it increases at its peak. The maximum temperature, soil temperature (morning) has a negative correlation while soil moisture, rainfall and relative humidity (evening) have a positive correlation with root-knot nematode population, number of root galls and number of egg masses/5 g root weight and root-knot index/plant. During summer months i.e. from March to June when temperature ranged between 33.2 to 38.2 °C and soil temperature (48.8 to 31.6 °C) relative humidity (19.00 to 93.00 percent moistures content (13.00 to 17.00 percent) the soil population of root-knot nematode of very low level. There was gradual increase in juvenile population from June to December. The highest soil population was observed in the month of December when the temperature ranged between (28.1 to 29.00 °C) soil temperature (32.00 to 32.7 °C), and relative humidity during the morning (91.1 to 96.6 percent) and evening (37.6 to 40.53 percent) with percent moisture content (18.0 to 20.0 percent).
