The effects of depleted oyster and colour mussel shells on the plenty of root-knot nematodes in stigma planted with love apple plants. Philippine science High schooltime Western Visayas. Bito-on, Jaro, Iloilo City. March 2010. Abstract Plant- bloodsucking 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 district treatments and crop rotation, but in that respect are undesirable features associated with each. Chitin has been office as a defacement amendment to control root-parasitic nematodes. Chitin is the main element of the cell w every(prenominal)s of fungi, the exoskeletons of arthropods, the radulas of mollusks and the beaks of cephalopods. This study conducted an examine to evaluate the effects of humbled oyster and green mussel shells on the population of root-knot nematodes in love apple plants. A tomato domain of a function in Brgy. Lanag, Leon was divided into 3 plots and each was divided into 4 subplots. For each plot, one subplot was enforce as control (no oppress shells). The other two subplots were practise with disordered 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 merge with the top 15 cm of the soil for each plant. Nematodes were extracted with the Baermann-funnel method acting from soil samples tranquil onward application of amendments and 4, 6, 8 weeks subsequently application. A complicated microscope was employ to view and count the nematodes roll up from samples collected. The gradual amplification in the population of nematodes from week 0 to 6 would look upon that in that respect is growth within the population of root-knot nematodes. There was a abate in the number of nematodes act in soil amend with oyster shells after week 6. There was no hearty difference between all of the groups during the...If you want to shit a full essay, order it on our website: Ordercustompaper.com
