Anino, Paolo Angelo G., Corteza, Zigmund Bryan P., Custodio, Vince Marvin T. The effects of depleted oyster and car park mussel shells on the pack of root-knot nematodes in stigma planted with love apple plants. Philippine science High School Western Visayas. Bito-on, Jaro, Iloilo City. March 2010. snitch Plant- epenthetic nematodes are know to be one of the great threats to crops throughout the world. Plant parasitic nematode problems have unremarkably been managed by chemical territorial dominion treatments and crop rotation, entirely there are undesirable features associated with to each one. Chitin has been use as a soil amendment to avow 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 breeding conducted an experiment to evaluate the effects of crushed oyster and green mussel shells on the population of root-knot nematodes in tomato pla nt plants. A tomato field in Brgy. Lanag, Leon was dissever 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. downcast 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 hebdomads later application. A complicated m icroscope was used to view and account 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 at heart the population of root-knot nematodes. There was a decrease in the upshot of nematodes present in soil amended with oyster shells after week 6. There was no significant difference among all of the groups during the...If you want to shit a full essay, baseball club it on our website: BestEssayCheap.com
