Other claims from this paper (19)
- Intervention effect M. incognita greatly suppressed most growth and yield parameters in susceptible Castlerock tomato.
- Intervention effect Resistant tomato was only slightly affected by M. incognita.
- Observation Susceptible tomato had higher fruit acidity, vitamin C and soluble solids.
- Observation Final nematode population, root gall index and reproduction factor were significantly higher in susceptible than resistant tomato.
- Association Vegetative growth decreased as initial nematode density increased.
- Association Root fresh weight increased with initial nematode density.
- Association Fruit yield per plant decreased with increasing initial nematode density.
- Intervention effect Average fruit weight decreased significantly at the highest stated initial density versus control.
- Intervention effect Fruit acidity and vitamin C content decreased at most nematode densities.
- Association Final nematode population increased with initial density.
- Observation Root gall index ranged from 0.0 in controls to 5.0 with inoculum.
- Association Cultivar and initial density interacted significantly for leaf fresh weight, chlorophyll and fruit yield, with resistant plants at zero density highest.
- Observation Resistant plants at zero initial density had the lowest root fresh weight.
- Observation The lowest final nematode population occurred at 4 ´ 103 with resistant tomato.
- Association Root gall index responded little to initial density in resistant tomato but strongly in susceptible tomato.
- Observation The lowest nematode reproduction factor occurred at 20´ 103 in resistant tomato.
- Intervention effect All organic manures improved tomato growth, yield and fruit quality parameters.
- Intervention effect Pigeon and poultry manures improved growth and yield more than rabbit and cow manures.
- Intervention effect Organic manures suppressed nematode population, root galling and reproduction; pigeon and poultry were stronger for galling and reproduction than cow and rabbit.
