Abstract

Rice (Oryza sativa L.) is cultivated under flooded lowland conditions and is a single biggest user of fresh water. Overexploitation of groundwater has caused serious problems in many parts of India including Haryana and Punjab. A new development in water saving technologies is the concept of aerobic rice. Rice is considered a drought sensitive crop species, however, aerobic rice withstand water stress. In the present investigation, different morphological and agronomical traits were studied in aerobic (MAS25, MAS26) and lowland (HKR47, PAU201, HBC 19 and PUSA1121) indica rice genotypes, grown under submerged and aerobic conditions in pots. Root length, shoot biomass, root biomass, yield and yield attributes declined in all lowland rice genotypes while, conversely, aerobic rice genotypes showed enhancement under aerobic environment. Better agronomic performance displayed by aerobic varieties may be due to longer, thick and dense root system in these rice genotypes.
