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.

Conservation Tillage and Weed Management Influencing Weed Dynamics, Crop Performance, Soil Properties, and Profitability in a Rice–Wheat–Greengram System in the Eastern Indo-Gangetic Plain

Agronomy, 2023
A three-year field experiment was carried out to assess the efficacy of various tillage and residue management practices, as well as weed management approaches, in a rice–wheat–green gram rotation.

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

Non-puddling rice cultivation increases subsequent soybean yield in a rice–soybean rotation system

Plant Production Science, 2020
Non-puddling rice cultivation would increase subsequent soybean yield. Soybean (cv. ‘Yukihomare’) was grown in farmers’ fields previously cultivated with puddled transplanted rice (Puddled Rice), non-puddled transplanted rice (Non-puddled Rice), and dry ...

The design of rice direct seeding machine [PDF]

Advances in Engineering Research, 2015
In order to change the existing status of big turning radius of the large direct seeding machines with diesel and gasoline as fuel and improve the low efficiency and time-consuming condition of the machine driven by human or animal, an electric rice planter was designed. The mechanical parts and circuit design had been finished.

Feasibility of mini-sprinkler irrigation system in direct seeded rice (Oryza sativa) in Indo-Gangetic plains of India

The Indian Journal of Agricultural Sciences, 2020
Surface irrigation methods in puddle transplanted rice (PTR) requires a huge amount of irrigation water and leads to decline in water table in rice (Oryza sativa L.) growing areas of Indo-Gangetic Plains (IGP) of India.

Rice Direct Seeding Method with Recycled-paper Mulching [PDF]

Plant Production Science, 1999
We developed a new direct hill seeding method, paper-mulched direct seeding (PMDS). In this method, recycled-paper sheets with rice (Oryza Sativa L.) seeds affixed are spread over a flooded paddy field just after puddling and leveling. Three or five rice seeds were sandwiched between biodegradable gauze or non-woven mesh, fixed to a hole (25 mm ...
