Abstract

Aerobic rice cultivation saves water and ensures higher grain yield. Although it is a new potential technology which ensures water saving and high yield, it has some limitations like weed and pest and disease problems. Several factors are responsible for the low productivity of rice. Of these, availability of irrigation water, soil nutrient status and outbreak of insect pests and diseases are major constraints for higher productivity (Pimentel, 1983). Nematodes are the major constraints responsible for continuous cropping obstacle in upland rice (Nishizawa et al. 1971). The root knot nematodes, Meloidogyne graminicola were the prominent pest problems reducing the yield of aerobic rice (J.C. and Matias 1995).
