Progress of Research on Phytohormone Interaction in Germination of Direct-Seeded Rice under Submergence

Agronomy, 2022
Due to rainfall, closed weeding of paddy fields and other reasons, submergence stress often occurs during the germination and emergence stages of direct-seeded rice (Oryza sativa L.), which leads to intensified anaerobic respiration, accelerated ...

Potential benefits of dry direct seeded rice culture : A Review

Fundamental and Applied Agriculture, 2019
Puddled transplanting is the major system of rice cultivation in many parts of the world. Transplanting system provides a high and stable yield. It is labour intensive and requires huge amount of irrigation water (1500 -2000mm).

Weed management in direct seeded rice: A review

Agricultural Reviews, 2017
Weeds are the major biological constraint in direct seeded rice (DSR) due to the concurrent emergence of competitive weeds, absence of water to suppress weeds at the time of seedling emergence and emergence of difficult to control weeds. Strategies on weed management in direct seeded rice depend on critical period of weed control, weed flora and method

Effects of Low Light after Heading on the Yield of Direct Seeding Rice and Its Physiological Response Mechanism

Plants, 2023
As a photophilous plant, rice is susceptible to low-light stress during its growth. The Sichuan Basin is a typical low-light rice-producing area. In this study, eight rice varieties with different shade tolerances were studied from 2021 to 2022.
