TL;DR: Assessment of variation in grain P concentrations among rice genotypes across diverse environments and the implications for field P balances at various grain yield levels found improved crop management and alternative breeding approaches may be required to achieve larger reductions ingrain P concentrations in rice.
Accumulation and partitioning of biomass, nitrogen, phosphorus and potassium among different tissues during the life cycle of rice grown under different water management regimes

TL;DR: In this paper, four water management treatments were used; (i) continuous flooding (CF) of soil from crop establishment to maturity, (ii) CF until tillering (4),weeks) and Alternative Wetting and Drying (AWD4) thereafter, (iii, CF until flowering (10,weeks), and AWD thereafter(AWD10).

TL;DR: Rice cultivars with higher capacity to accumulate N, P andK, and longer crop duration ensured higher grain DW while seed P and K concentrations are not good indicators to select promising rice cultivars to low-fertile soils with severe P limitation.

Age-related morphological and physiological responses of irrigated rice to declined soil phosphorus and potassium availability

TL;DR: The most sensitive growth stage of rice to slight deficiencies of P and K was the tillering stage, and knowledge on the morphological and physiological shoot and root responses that can be observed during the lifecycle of a rice plant, and the growth stage at which those responses are prominent in response to declining soil phosphorus (P) and potassium (K) availabilities can be used when identifying the development of soil P andK limitations hindering the optimal growth of rice plant.

Growth, root adaptations, phosphorus and potassium nutrition of rice when grown under the co-limitations of phosphorus, potassium and moisture
TL;DR: In this article, an experiment was conducted using two rice varieties [long (LD) and short (SD) duration, two moisture conditions (continuous flooding and top-soil drained after flowering), and five fertilizer treatments (with and without the applications of P and/or K).
