Abstract

The increasing shortage of water resources accelerates the development and adoption of aerobic rice system with several advantages and promotes mechanical cultivation. It has been observed that by reducing water use during land preparation and limiting seepage, percolation, and evaporation, the aerobic rice made use of only 51% water and improved crop productivity by 32-88%, than flooded rice. The system of aerobic cultivation also saves labour as compared to conventional system. Our present study reports on the differential response of traditional upland varieties/germplasm including aerobic rice genotypes (selected from breeding trials) against rice root knot nematode, M. graminicola (Golden and Birchfield, 1965). The experiments were conducted under net house condition to screening 108 varieties/germplasm in 6 - 8 inch earthen pots. The plants were watered on alternate day or need based to maintain aerobic condition.
