Integrated Management of Weeds in Direct-Seeded Rice in Cambodia

Agronomy, 2020
The objective of this work was to determine the value of improved establishment methods and herbicide applications as alternatives to high seeding rates to improve weed suppression in rice. Field experiments were carried out in 2010 and 2011 to determine

The Effects of Paclobutrazol Seed Soaking on Biomass Production and Yield Formation in Direct-Seeded Rice

Agronomy, 2023
Direct-seeded rice has been widely adopted in Asia in recent years. However, its low and unstable yields severely limit the increase in rice production and directly affect food security.

Optimization of One-Time Fertilization Scheme Achieved the Balance of Yield, Quality and Economic Benefits of Direct-Seeded Rice [PDF]

Plants, 2023
There is limited information available to assess the impact of one-time fertilization on the yield, quality, and economic benefits of direct-seeded rice. This study reports the effects of three one-time fertilizer treatments (BBU1, BBU2, and BBU3) on the

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 ...

Energy assessment of different rice–wheat rotation systems

Food and Energy Security, 2021
Food and energy security are important issues that threaten human survival and development. The rice–wheat rotation system provides a stable source of food for more than 20% of the world's population, but there have been no reports on the energy balance ...

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.
