Effects of Controlled Release Urea Formula and Conventional Urea Ratio on Grain Yield and Nitrogen Use Efficiency of Direct-Seeded Rice

Agriculture, 2022
A one-off application of bulk blend urea (BBU), which includes a controlled release urea formula and conventional urea, has been recommended to simplify fertilisation management for direct-seeded rice.

Direct-Seeded Rice in Nepal

East African Scholars Journal of Agriculture and Life Sciences, 2021
Quick Response Code Abstract: To over half the world's population, rice is the primary staple food. In recent years, there has been a shift from transplanted rice to direct-seeded rice cultivation mainly driven by seasonal scarcity of agricultural labor,

Effect of Biochar on Soil Physiochemical Properties and Bacterial Diversity in Dry Direct-Seeded Rice Paddy Fields

Agronomy, 2022
The effects of biochar application on dry direct-seeded rice paddies remains unclear. Therefore, we applied biochar to dry direct-seeded rice paddy fields over 3 consecutive years to assess its effects on soil physicochemical properties and bacterial ...

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

Weed management in direct seeded rice: A review [PDF]

International Journal of Chemical Studies, 2020
Direct seeding is done by sowing of pre-germinated rice seeds under puddled condition either manually or by drum seeding methods. Direct seeded rice (DSR) cultivation needs only 34 per cent of the total labour requirement and saves 29 per cent of the total cost of the transplanted rice.

Identification of a Seed Vigor–Related QTL Cluster Associated with Weed Competitive Ability in Direct–Seeded Rice (Oryza Sativa L.)

Rice, 2023
Direct seeding of rice ( Oryza sativa L.) is a low-labor and sustainable cultivation method that is used worldwide. Seed vigor and early vigor are important traits associated with seedling stand density (SSD) and weed competitive ability (WCA), which are

Agronomic and Environmental Determinants of Direct Seeded Rice in South Asia

Circular Economy and Sustainability, 2022
Rice ( Oryza sativa L.) is the staple food of more than 50% of the world’s population. Manual puddled transplanted rice (PTR) system is still the predominant method of rice establishment. However, due to declining water tables, increasing water scarcity,
