Background & Objective: Due to the P reactions with soil components not all the P applied to soils is available to plants, hence, it is necessary to improve P use efficiency. Application of organic compound (e.g. municipal sewage sludge) as a P fertilizer into soil is one the way to enhance soil P supply. The P availability issue is much more important in saline lands because in addition to soil components, salinity directly affects nutrient uptake and translocation (Bouras et al., 2022). Therefore, this study was performed to compare the effect of the single and combined applications of municipal sewage sludge (MSS) and triple superphosphate (TSP) on some growth properties and P uptake of quinoa under non-saline and saline conditions.
Materials and Methods: A pot experiment was laid in a completely randomized factorial design with 3 MSS levels (0, 0.25 and 0.5% w/w which were named M0, M1 and M2, respectively), 3 TSP levels (0, 29 and 38 mg kg-1 soil which were named T0, T1, and T2, respectively), 2 f irrigation water salinity levels (2 and 12 dS m−1, which were named non-saline and saline, respectively) and 3 replicates. Three months after planting, the plants were harvested for recording plant height, stem diameter and panicle length. The shoots were oven dried at 70°C and the shoot dry weight, 1000-seed weight and seed yield were measured. Additionally, the shoot dry was crushed, ashed at 450°C and extracted in 0.1 M HCl solution to determine the content of P by molybdate method (Murphy and Riley, 1962). Furthermore, soil within the pots was air dried, crushed gently and analyzed for determination of EC and soil organic carbon. Statistical analyses were performed with MSTATC 1.42 and the means were compared by Duncan’s test at p < 0.05.
Results: Regarding the three-fold interaction, all of the studied parameters in saline condition were significantly lower than non-saline condition. In other words, increase of salinity had a negative effect on growth of quinoa. However, application of MSS and TSP (especially combined treatments) could improve its growth traits. In non-saline condition, the maximum values of shoot dry weight, 1000-seed weight and seed yield were found in T2M2 which were 2.8, 1.2 and 3.1 times higher than that of the T0M0 treatment, respectively. Likeness, the higher amount of shoot P uptake (86.9 mg pot-1) was observed in the T2M2. Nevertheless, T1M2 was the best treatment in the saline condition due to there was no significant difference between studied parameters of this treatment and T2M2. Furthermore, the absence significant effect of MSS on soil EC and its positive effect on soil organic carbon were another advantageous aspect of this compound.
Conclusion: The effectiveness of the treatments on studied parameters were as follow: single application of TSP< single application of MSS
