Phosphorus placement effects on phosphorous recovery efficiency and grain yield of wheat under no-tillage in the Humid Pampas of Argentina
No-till (NT) affects dynamics of phosphorus (P) applied. Wheat response to P fertilization can be affected by available soil P, grain yield, placement, rate, and timing of fertilization. Furthermore, mycorrhizal associations could contribute to improving plant P uptake. Three experiments were used...

| description | No-till (NT) affects dynamics of phosphorus (P) applied. Wheat response to P fertilization can be affected by available soil P,
grain yield, placement, rate, and timing of fertilization. Furthermore, mycorrhizal associations could contribute to improving
plant P uptake. Three experiments were used to evaluate P rate (0, 25, and 50 kg P ha−1) and fertilizer placement (broadcasted
or deep-banded) effects in NT wheat on P recovery efficiency (PRE) yield and arbuscular mycorrhizal colonization (AMC) which
was assessed in one experiment. Fertilization increased dry matter (DM) and accumulated P. Broadcasted P produced lower P
accumulation than deep-banded P only at tillering. Phosphorus rate decreased PRE, and placement method did not affect it. Grain
yield response was increased by P rate (857 and 1805 kg ha−1 for 25 and 50 kg P ha−1, resp.) and was not affected by placement
method (4774 and 5333 kg ha−1 for broadcasted and deep-banded, resp.). Deep-banded P depressed root AMC compared with
broadcast applications. Highest AMC in P broadcasted treatments could help to explain the lack of differences between placement
methods. These results indicate thatMollisol have low P retention capacity.Therefore, broadcasted P could be used as an alternative
of fertilizer management for NT wheat. |
