Abstract
Plant- epenthetic nematodes are know to be one of the greatest threats to crops throughout the world. Plant parasitic nematode problems have commonly been managed by chemical territorial dominion treatments and crop rotation, but there are undesirable features associated with each. Chitin has been use as a soil amendment to control root-parasitic nematodes. Chitin is the main gene of the cell walls of fungi, the exoskeletons of arthropods, the radulas of mollusks and the beaks of cephalopods.
This study conducted an experiment to evaluate the effects of crushed oyster and green mussel shells on the population of root-knot nematodes in tomato plants. A tomato field in Brgy. Lanag, Leon was divided into 3 plots and each was divided into 4 subplots. For each plot, one subplot was utilize as control (no crushed shells). The other two subplots were use with crushed oyster and green mussel shells, respectively.
Each subplots planted with tomato plants was applied with railyard g crushed oyster shells and 1000 g green mussel shells. Crushed shells were mixed with the top 15 cm of the soil for each plant. Nematodes were extracted with the Baermann-funnel method from soil samples tranquil before application of amendments and 4, 6, 8 weeks after application. A complicated microscope was used to view and count the nematodes collected from samples collected.
The gradual amplification in the population of nematodes from week 0 to 6 would look upon that there is growth within the population of root-knot nematodes. There was a decrease in the number of nematodes present in soil amended with oyster shells after week 6. There was no significant difference between all of the groups during the...If you want to shit a full essay, order it on our website: Orderessay
