“…Results of Exp.1 confirmed that the effect of FYM application on both P uptake and biomass production of rice largely differed among soils under flooded conditions. Our previous studies indicated that the effect of FYM application on rice production and P uptake was much clearer under the upland ecosystem relative to the lowland ecosystem (Andriamananjara et al, 2016(Andriamananjara et al, , 2018, but the specific soil chemical factors that caused different responses to FYM application have not been fully understood. Our hypothesis was that FYM would have a greater effect on P uptake and consequently on biomass production for rice in soils with low available P based on soil P Ox , TotC, and pH.…”

“…P deficiency to rice is commonly observed in Madagascar, the second largest rice producer in SSA, which is due to high levels of P-fixing iron (Fe) or aluminum (Al) oxyhydroxides in soils (Nishigaki et al, 2019) and little P fertilizer inputs (Rabeharisoa et al, 2012;Tsujimoto et al, 2019). Our previous on-farm experiments demonstrated that the yield gap between P-fertilized and non-P-fertilized treatments could reach up to 2.5 t ha -1 in the central highlands of Madagascar (Andriamananjara et al, 2016).…”

“…On-farm trials in the central highland of Madagascar showed large field-to-field variations in the effect of FYM application on increases in grain yield (0.11 to 1.10 t ha −1 ) and P uptakes (0.26 to 2.92 kg ha −1 ) of rice under irrigated lowland conditions (Andriamananjara et al, 2016). In the same study, the effect of FYM application tended to be high in soils with limited P availability in terms of pH and contents of oxalate-extractable P (P Ox , hereafter).…”

Farmyard manure (FYM)mixtures of animal droppings, crop residues, and fodder that are piled nearby homesteadsis a major nutrient source for smallholder farmers in Sub-Saharan Africa. However, its application effect has not been fully understood on typical P-deficient soils in tropics and in particular under anaerobic conditions. This study assessed the effect of FYM on irrigated rice in relation to soil propertiesoxalate-extractable P (P Ox), pH, and total C (TotC)that are important indicators of soil P deficiency in the region. The first pot experiment was conducted with a factorial combination of FYM (0 and 20 g kg-1) and mineral P (0 and 100 mg kg-1) applications using six paddy soils differing in the aforementioned soil properties. The second pot experiment was conducted in a factorial combination of FYM and mineral P using the isotope dilution technique. In both experiments, the effect of FYM application on biomass and P uptake of rice per P applied was nearly equivalent to that of mineral P and was greater in soils with lower TotC and lower pH with negligible effect of P Ox. The isotope tracing suggested that the FYM application might increase rice P uptake by solubilizing non-labile P pools in soils while mineral P was directly used by rice from labile P pools. The results indicated that the FYM should be most effective in soils with low TotC and low pH, and its application could enable the use of insoluble P pools in soils and enhance P uptake of rice under P-deficient and anaerobic conditions.

“…Linquist et al (2007) reported an improvement in yield following FYM application, but did not find the evidence of P uptake improvement and also identified alarge year-to-year variation in rain-fed lowlands in Laos. On the other hand, Andriamananjara et al (2016) reported no effect of FYM on grain yield and plant P uptake in a P-deficit soil in the central highlands of Madagascar. These studies demonstrated the contrasting results.…”

“…Thus, plant P uptake is severely inhibited even under flooding conditions (Rabeharisoa et al, 2012). Previous on-farm experiments have demonstrated that the yield gap between P-fertilized and non-P-fertilized treatments could reach up to 2.5 t ha −1 in the central highlands of Madagascar (Andriamananjara et al, 2016). Moreover, yield responses to P fertilizer were found to be greater than responses to any other macro nutrients (Balasubramanian et al, 1995).…”

Phosphorus (P) deficiency is a major yield constraint for lowland rice production in the tropics. As P-fertilizer resources are finite, alternative fertilizer management is needed for sustainable rice production. We examined whether farmyard manure (FYM), a major nutrient source for smallholder farms, can overcome issue in typical P-deficient lowlands in the central highlands of Madagascar. A multi-location trial in sites varying in altitude and soil P availability, clarified that the effect of both FYM and mineral P fertilizer application on grain yield greatly increased at higher elevation and when the soil oxalate-extractable P content was <100 mg kg −1 . The yield increase was attributable to improved grain fertility, probably because FYM and mineral P applications decreased days to flowering and avoided low temperatures at late growth stages. Nutrient uptake assessment clarified that despite its relatively low P content, FYM had an equivalent effect on plant P uptake to those of mineral P fertilizer. We concluded that FYM application was effective in low-P availability soils at high altitude, as alternative of mineral P fertilizer. Further monitoring is required to assess the effect of consecutive FYM use on grain yield and plant nutrient uptake in the context of cold stress induced by P deficiency.

Background Phosphorus (P) deficiency remains a serious problem for lowland rice cultivation in Sub‐Saharan Africa. Locally available organic materials (OM) are potential amendment resources, but they vary widely in nutrient composition. How different OM affect P availability and rice production under different soil types remains poorly understood. Aims We aimed to determine soil responses to OM application varying in carbon (C) and P contents on P uptake, rice production, and P availability. Methods A pot experiment with eight different soils from lowland rice fields amended with four different farmer‐produced OM at an equal dose of 7.5 g kg–1 soil; and an incubation experiment with six soils amended with cellulose and two OM applied at the same C dose were conducted. Results An OM associated with high P and low C:P ratio increased shoot biomass and P uptake of rice in all soils by two‐ and threefold, respectively, compared to the control treatment. Low P saturation in soils (low P:Fe in oxalate extract) produced greater OM effects. Shoot biomass and P uptake decreased significantly in one soil with a high P saturation following application of the other three OM. Although increased soil P solubilization was observed with the addition of fresh C, OM effects on P availability were mostly attributed to their direct P supply. Conclusion OM with high P and low C:P ratio is effective in improving P availability for rice in P‐deficient lowland rice soils.
