Developing fertilizer recommendations for rice in Sub-Saharan Africa, achievements and opportunities por Bado, V.B., Djaman, K., Mel, V.C.

“…Fertilizer is a powerful productivity-enhancing input; nevertheless, farmers of SSA use only 5–9 kg ha−1 of fertilizer, which is ten times lesser than Latin America and Asia (50 and 80 kg ha−1, respectively). Rice (Oryza sativa) is one of the most important food crops of SSA, and its consumption is growing faster than any other commodity in Africa. …”

Where the wild things are: genetic associations of environmental adaptation in the Oryza rufipogon species complex por Wang, Diane R., Kantar, Michael B., Murugaiyan, Varunseelan, Neyhart, Jeffrey

“…Distributions of allele frequencies at significant loci across subpopulations of cultivated Oryza sativa indicate that, in some cases, adaptive variation may already be present among cultivars, although evaluation in cultivated populations is needed to empirically test this. …”

What happens at night? Physiological mechanisms related to maintaining grain yield under high night temperature in rice por Xu, Jiemeng, Misra, Gopal, Sreenivasulu, Nese, Henry, Amelia

“…High night temperature (HNT) causes substantial yield loss in rice (Oryza sativaL.). In this study, the physiological processes related to flag leaf dark respiration (Rn) and grain filling under HNT were explored in a multi‐parent advanced generation intercross population developed for heat tolerance (MAGICheat) along with selected high temperature tolerant breeding lines developed with heat‐tolerant parents. …”

Does Nilaparvata lugens gain tolerance to rice resistance genes through conspecifics at shared feeding sites? por Ferrater, Jedeliza B., Horgan, Finbarr G.

“…We created optimal conditions for intraspecific interactions on the same rice, Oryza sativa L.
