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 ...

Germination and Growth Performance of Water-Saving and Drought-Resistant Rice Enhanced by Seed Treatment with Wood Vinegar and Biochar under Dry Direct-Seeded System

Agronomy, 2022
Dry direct-seeded rice (dry-DSR) is an efficient, resource-saving and environmentally friendly cropping system. The employment of water-saving and drought-resistant rice (WDR) for dry direct-seeding can better meet the needs of dry-direct seeding systems.

Changes of Weedy Rice Occurrence in Repeated Wet Direct Seeding and Alternate Transplanting/Wet Direct Seeding of Rice

Weed & Turfgrass Science, 2013
Weedy rice is one of the major problems in direct-seeded rice field, resulting in poor rice quality and low grain yield. This study was carried out to evaluate the conversion effect to machine transplanting after wetdirect-seeding for 3 years on weedy rice occurrence, in comparison of repeated wet-direct-seeding.

A REVIEW ON WEED IN DIRECT-SEEDED RICE (DSR)

Sustainability in Food and Agriculture, 2021
Oryza sativa, cereal crop grown worldwide which feeds 60% of world. DSR, feasible and resource conserving technique of rice cultivation is gaining popularity, but due to weed infestation, crop experience a yield loss from 15%-100%. Various journals were assessed and books were consulted with the objective of compiling the various weeds of DSR and their
