Resource conservation technology for sustainable productivity of intensive rice-based cropping pattern in Bangladesh por Mobarak, Hossain, Mahfuza, Begum, Moshiur, Rahman, Abul, Hashem, Bell, Richard

“…Summer rice (BRRI hybrid dhan6), mustard (BARI Mustard 14) and winter rice (BRRI dhan28) were grown under, T1: Conventional tillage (CT) + three hand weeding (Control) and T2: Pre-plant herbicide (PRE) + strip tillage (ST) + pre-emergence herbicide (PE) + post-emergence herbicide (PO) with two levels of crop residue mulching, M0: no-mulch and M50: 50% standing mulch. The CT consisted of two primary tillage operations by a two-wheel tractor, and ST had done by a Versatile Multi-crop Planter in a single-pass process. …”

Machine learning reveals spatiotemporal genome evolution in Asian rice domestication por Ohyanagi, Hajime, Goto, Kosuke, Negrão, Sónia, Wing, Rod A., Tester, Mark A., McNally, Kenneth L., Bajic, Vladimir B., Mineta, Katsuhiko, Gojobori, Takashi

“…From the correspondence between our wide IRs and the so-called selective sweep regions, we provide a definitive answer to a long-standing controversy over the evolutionary origin of Asian rice domestication, single or multiple origins: It heavily depends upon which regions you pay attention to, implying that wider genomic regions represent immediate short history of Asian rice domestication as a likely support to the single origin, while its ancient history is interspersed in narrower traces throughout the genome as a possible support to the multiple origin.…”

Mechanisms associated with tiller suppression under stagnant flooding in rice por Zhu, Guanglong, Chen, Yutiao, Ella, Evangelina S., Ismail, Abdelbagi M.

“…To explore physiological mechanisms associated with tillering suppression under SF, three contrasting genotypes (Swarna and Swarna‐Sub1, both sensitive and IRRI154, tolerant) were evaluated under standing water depths of 0, 5, 30 and 50 cm. SF significantly suppressed tiller formation but increased plant height, root biomass, shoot elongation (ratio of plant height before and after flooding), leaf emergency and non‐structural carbohydrate (NSC) concentration (in root–shoot junction) in all genotypes at the early stage of development. …”
