Aerobic Rice: Smart Technology of Rice Cultivation

Abstract

Rice is one of the most important food crops that feed over half of the global population and biggest consumer of fresh water diverted from irrigation. Water scarcity is burning issue of agriculture, outcome of climate change and unpredictable rainfall. It threatens the future of irrigated rice cultivation. Researchers developed new technology called -Aerobic Rice‖ to cope up with present situation. Rice is grown in well-drained, non-puddled and non-saturated soils. Aerobic rice cultivar has drought tolerance capacity as well as yield potentiality. Aerobic rice can save about 50% of irrigation water in comparison to lowland rice. To overcome increasing water scarcity problem, this is better choice for both present and future.

Mapping quantitative trait loci for water uptake of rice under aerobic conditions

“…Some upland rice varieties have been observed to be adapted in aerobic condition due to their droughtresistant characteristics, but these do not attain similar yield as the high-yielding lowland varieties. Recent studies in aerobic rice breeding programs have indicated that in order for rice varieties to be suitable for aerobic cultivation, new genotypes which possess both the vigorous root growth of upland varieties for drought tolerance, combined with the high-input responsiveness of lowland varieties for high yield must be developed (Dey et al, 2018;Du et al, 2015).…”

Physiological, Agronomic, and Grain Quality Responses of Diverse Rice Genotypes to Various Irrigation Regimes under Aerobic Cultivation Conditions

“…Another significant benefit of cultivating aerobic rice is preventing the loss of essential micronutrients from the soil and decreasing methane gas emissions as a product of flooded fields [ 11 ]. In this perspective, Liu et al [ 8 ], Sandhu et al [ 12 ], Fukai and Mitchell [ 13 ], Dey et al [ 14 ] and Bhutto et al [ 15 ] explained that aerobic rice cultivation represents an innovative and sustainable approach to rice farming that significantly diverges from traditional methods. It primarily addresses water scarcity in rice cultivation by promoting water efficiency and reducing the dependency on flooded conditions typically associated with paddy rice farming.…”

Response of varied rice genotypes on cell membrane stability, defense system, physio-morphological traits and yield under transplanting and aerobic cultivation

“…Rice ( Oryza sativa L.) is an essential staple crop that secures food for almost two-thirds of the world's population 1 . The cultivation of rice occupies about twenty percent of the agricultural land area planted for cereals 2 . In Egypt, rice production faces many grand challenges such as freshwater scarcity, salt stress, the high cost of inputs, and overpopulation.…”
