Improved Phosphorus (P) Uptake and Yield of Rainfed Wheat Fed with P Fertilizer by Drought-Tolerant Phosphate-Solubilizing Fluorescent Pseudomonads Strains: a Field Study in Drylands

This research aimed to evaluate the effect of empty fruit bunches (efb) compost, phosphate-solubilizing bacteria (PSB), lime, and types of P fertilizer on the growth and availability of Phosphorus and P uptake in the pre-nursery (PN) oil palm seedlings in latosols. The pot experiments were arranged in a Factorial Completely Randomized method. The first factor was the application of efb compost: without efb compost, efb compost, without efb compost + PSB, and without efb compost + lime. The second factor was the types of P fertilizer: SP-36, RP, guano, and NPKMg + Urea as a control. The results showed that the combination of without efb compost +lime and RP fertilizer produces the highest number of leaves. The influence of a single factor showed that the application of without efb, efb compost, without efb compost +PSB, without efb compost + lime, resulted in the same growth of seedlings, except on plant height and the length of the leaf. The various types of P fertilizer led to the same growth of seedlings except for stem diameter. The highest available P was obtained in the combination of without efb compost + PSB with SP-36 fertilizer, which was 631.1% compared to control (without efb compost and NPKMg, Urea) and the lowest in the combination of without efb compost + lime with (NPKMg, Urea). The treatment without efb compost + lime with SP-36 fertilizer increased P uptake of leaves by 55.6% and stem by 47.1% compared to control.

Phosphorus Levels

A pot experiment was conducted to investigate the effect of different phosphate solubilizing bacteria (PSB) with various levels of inorganic phosphorus (P) on the growth and yield of wheat with three soil at the Microbiology laboratory, Soil Science Division, Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh. Four levels of P fertilizer (P0 : Without P, P24 : 24 mg P kg-1 soil, P36 : 36 mg P kg-1 soil and P48 : 48 mg P kg-1 soil) were assigned as main factors and six PSB inoculants with an uninoculant (I0, MR1, IL1, IW1, IC2, RC1and MW1) were assigned as sub factors in a factorial CRD. The soil used for the experiment belong to three Agroecological Zones (AEZs) such as AEZ 9 from the BAU farm, Mymensingh, AEZ 28 from the BADC farm, Madhupur, Tangail and AEZ 11 from the BINA substation farm, Ishurdi, Pabna. Eight kilogram soils were taken in each of the plastic pot. PSB were applied as broth inoculants with the wheat seeds (var. Shatabdi) before sowing. Irrespective of the PSB inoculants, 36 mg P kg-1 soil gave the highest grain and straw yield of wheat pot-1 with Mymensingh and Mdhupur soil while 48 mg P kg-1 soil showed the highest wheat yield pot-1 with Ishurdi soil. Among the PSB inoculants, MR1 showed the maximum grain and straw yields of wheat pot-1 followed by MW1. The PSB inoculant MR1 with 36 mg P kg-1 soil had better performance in terms of total P uptake and grain and straw yields of wheat.DOI: http://dx.doi.org/10.3329/jesnr.v6i1.22069 J. Environ.

P Utilization

In a phytotron experiment, wheat was grown under two levels of atmospheric CO2 [ambient (385 ppm) vs. elevated (650 ppm)], two levels of temperature (ambient vs. ambient +3°C) superimposed with three levels of phosphorus (P) fertilization: 0, 100, and 200% of recommended dose. Various measures of P acquisition and utilization efficiency were estimated at crop maturity. In general, dry matter yields of all plant parts increased under elevated CO2 (EC) and decreased under elevated temperature (ET); however, under concurrently elevated CO2 and temperature (ECT), root (+36%) and leaf (+14.7%) dry weight increased while stem (–12.3%) and grain yield (–17.3%) decreased, leading to a non-significant effect on total biomass yield. Similarly, total P uptake increased under EC and decreased under ET, with an overall increase of 17.4% under ECT, signifying higher P requirements by plants grown thereunder. Although recovery efficiency of applied P fertilizer increased by 27%, any possible benefit of this increase was negated by the reduced physiological P efficiency (PPE) and P utilization efficiency (PUtE) under ECT. Overall, there was ~17% decline in P use efficiency (PUE) (i.e. grain yield/applied P) of wheat under ECT.

The Impact

Optimizing the phosphorus (P) application rate can increase grain yield while reducing both cost and environmental impact. However, optimal P rates vary substantially when different targets such as maximum yield or maximum economic benefit are considered. The present study used field experiment conducted at 36 experiments sites for maize to determine the impact of P application levels on grain yield, plant P uptake, and P agronomy efficiency (AEP), P-derived yield benefits and private profitability, and to evaluated the agronomically (AOPR), privately (POPR), and economically (EOPR) optimal P rate at a regional scale. Four treatments were compared: No P fertilizer (P0); P rate of 45–60 kg ha−1 (LP); P rate of 90–120 kg ha−1 (MP); P rate of 135–180 kg ha−1 (HP). P application more effectively increased grain yield, reaching a peak at MP treatment. The plant P uptake in HP treatment was 37.4% higher than that in P0. The relationship between P uptake by plants (y) and P application rate (x) can be described by the equation y = −0.0003x2 + 0.1266x + 31.1 (R2 = 0.309, p < 0.01). Furthermore, grain yield (y) and plant P uptake (x) across all treatments also showed a significant polynomial function (R2 = 0.787–0.846). The MP treatment led to highest improvements in P agronomic efficiency (AEP), P-derived yield benefits (BY) and private profitability (BP) compared with those in other treatments. In addition, the average agronomically (AOPR), privately (POPR), and economically optimal P rate (EOPR) in 36 experimental sites were suggested as 127.9 kg ha−1, 110.8 kg ha−1, and 114.4 kg ha−1, which ranged from 80.6 to 211.3 kg ha−1, 78.2 to 181.8 kg ha−1, and 82.6 to 151.6 kg ha−1, respectively. Economically optimal P application (EOPR) can be recommended, because EOPR significantly reduced P application compared with AOPR, and average economically optimal yield was slightly higher compared with the average yield in the MP treatment. This study was conducive in providing a more productive, use-effective, profitable, environment-friendly P fertilizer management strategy for supporting maximized production potential and environment sustainable development.

Spanish Research

Struvite (MgNH4PO4·6H2O) production is widely studied as a way to remove phosphorus (P) from wastewater and generate a potentially marketable P fertilizer, but its effects on crops have yet to be researched more thoroughly. This study was conducted to evaluate struvite recovered by the Spanish Research Council (CSIC) pilot process (STR) as a source of P for lettuce (Lactuca sativa L.) by comparing its effectiveness with that of single superphosphate (SUP), a common P fertilizer derived from phosphate rock. In a greenhouse pot experiment, a P-deficient loamy sand soil was amended with either SUP or STR at P rates of 0, 4, 8, 12, 16, and 20 mg·kg−1. Nitrogen and potassium were uniformly supplied to all treatments. The response of lettuce head fresh weight and P uptake to P rate exhibited statistically significant quadratic relationships for both SUP and STR. With respect to SUP, STR was significantly more effective in increasing lettuce yield and P uptake, probably because of the larger amount of magnesium (Mg) incorporated with this material and a synergistic effect on P uptake. This work supports previous findings based on other test crops in suggesting that STR can be a P source attractive to the fertilizer market with additional agronomic and environmental benefits such as providing available Mg and nitrogen, helping attenuate consumption of phosphate rock, and reducing release of P by discharge of treated wastewaters to surface and groundwater systems.
