Amaranthus
species is one of the plants often considered as the most
important green leaf vegetable in Nigeria and other countries. Its production has been
plagued with an array of factors including incidence of insect pest. This experiment took
place in Agricultural farm of University of Benin, Edo state Nigeria from February to
April 2013 and 2014. The aim was to investigate the effect of Nutrient and Variety on
Insect Pest infestation of
Amaranthus spp. The experimental design used was completely
randomized design with three replicates comprising a factorial combination of three types
of Soil and three varieties of Amaranth. The result showed that
Amaranthus cruentus
suffered more insect pest attack than other
Amaranthus used and that Amaranths planted
on poultry manure attracted more insect pests than Amaranths planted on other Nutrients.
These results can be employed as part of cultural control methods in the management of
insect pests of Amaranths.
