“…A higher supply of P between Zadoks (Zadoks et al 1974) 31 and 47 (before heading) resulted in a higher grain yield compared with P added at Zadoks 91-92 (ripening) (Römer and Schilling 1986). Römer and Schilling (1986) proposed that the addition of P before the emergence of the head allowed the plant to produce a higher number of fertile heads per unit area resulting in a higher yield. This was compared with P-deficient crops that conserved sufficient P to sustain the survival of at least one fertile head on each plant.…”

Potential for foliar phosphorus fertilisation of dryland cereal crops: a review

2010

Although not commonly used in dryland cropping systems to date, foliar phosphorus (P) fertilisation may allow a tactical response to prevailing seasonal climatic conditions, with the added benefit of reduced input costs at sowing. However, variable outcomes have been reported from field trials predominantly conducted in the USA, and to a lesser degree in Australia. The effectiveness of foliar P is dependent on soil P status, soil water status, crop type, fertiliser formulation and prevailing climatic conditions. This review argues that the potential of foliar P fertilisation in Australian dryland cereal cropping could be enhanced by altering formulations for enhanced leaf penetration using adjuvants, and by accurately assessing the responsiveness of sites before application. This review demonstrates that it is important to use appropriate techniques such as isotopic labelling, to measure the efficacy and mode of action of foliar formulations.

“…Wheat Forage and Grain response to P application rates (Romer and Schilling, 1986), prediction of wheat P requirement is more accurate using forage as the response factor than grain. Also, unlike with forage, poor grain response to applied P may have been due to the effects of confounding factors as the season progressed.…”

Hard Red Winter Wheat Cultivar Responses to a pH and Aluminum Concentration Gradient

et al. 2007

Aluminum (Al) toxicity is a major yield‐limiting factor in winter wheat production in many parts of the world. The use of Al‐tolerant cultivars reduces the impact of this problem and is common to the southern Great Plains where wheat is managed as a dual‐purpose crop. However, no quantitative data exist on the Al tolerance ranking of winter wheat cultivars often grown in a dual‐purpose management system. This study was established to classify on a field scale the Al tolerance of common winter wheat cultivars (Ok101, Ok102, 2137, 2174, Jagger, Jagalene, Custer, and AP502CL). Fall forage yield of each cultivar was harvested by hand clipping. Soil samples were collected at the same time and analyzed for pH and Al saturation (Alsat). Grain was hand‐harvested in June of each year from the same rows harvested for forage. Cultivar differences (P < 0.1) were found in forage and grain yields for the Alsat > 30% range. Al tolerance based on grain yield ranked as follows: 2137 > Jagalene = Ok101 > Jagger = 2174 ≥ Ok102 > Custer = AP502CL. Al tolerance based on forage yield ranking was similar to that of grain: 2137 > Ok101 = Jagalene = Jagger > 2174 = Ok102 > Custer = AP502CL. Grain yield seemed to be less affected by Alsat than forage yields. The use of Al‐tolerant winter wheat cultivars may minimize producers' risk of crop loss; therefore, this ranking of Al tolerance should help winter wheat producers make informed decisions if they have acid soils with high Al content and no other remedies available.

“…El menor contenido de este nutriente correspondió a S. cereale, la especie con mayor cantidad de plantas por maceta debido a su corto ciclo anual. La mayor cantidad de sistemas radicales en estado inicial de desarrollo, renovados por la siembra anual, pudo en este caso determinar un mayor requerimiento de fósforo (Römer & Schilling, 1986).…”

resumenLas interacciones entre la vid y especies herbáceas pueden involucrar competencia por recursos y alelopatía. Se presume que determinados cultivos de cobertura y malezas poseen efectos alelopáticos sobre el crecimiento de las cepas. Los objetivos del trabajo fueron: a) evaluar el efecto de los lixiviados de riego de diversas coberturas vegetales sobre plantas de vid y b) determinar su efecto inhibitorio sobre la germinación de semillas. Se efectuaron experimentaciones de campo e invernadero, con cultivos de cobertura y vides en macetas. Se utilizaron 11 lixiviados de diferentes cubiertas vegetales y un testigo con suelo descubierto, con un diseño completamente al azar y cinco repeticiones. Se evaluó expresión vegetativa y productiva de las vides. Se realizaron pruebas de germinación sobre semillas, utilizando lixiviados del riego y diferentes concentraciones de la solución acuosa. No se detectó efecto negativo en el crecimiento vegetativo ni en la producción de uva en plantas jóvenes de vid, ni tampoco en la germinación de otras especies vegetales. El ensayo en macetas evidenció que existe una interacción entre las coberturas y el suelo, mediante la cual el balance de nutrientes es alterado según la especie, y puede afectar positiva o negativamente el crecimiento de las vides. and b) to determine its inhibitory effect on seed germination. Greenhouse and field experiments were conducted with cover crops and potted vines. Eleven leachates from different green covers and a bare soil control were tested with a randomized design and five replicates. The vegetative and productive expression of the vines was evaluated. Seed germination tests were conducted using leachate from irrigation and different concentrations of the aqueous solution. Adverse effects were not detected in the vegetative growth, the grape production in young vines or the germination of other plant species. The pot trial showed that there is an interaction between cover crops and soil, whereby the balance of nutrients is altered depending on the species. This balance can positively or negatively affect the growth of the vines.
