The phosphorus (P) requirements of spring wheat (Triticum aestivum L.) are well known for all soils in south-western Australia; but the P requirements of field pea (Pisum sativum L.) and canola (Brassica napus L.), which are grown in rotation with wheat on marginally acidic to alkaline soils in the region, are not known. In a glasshouse study, the P requirements of field pea and wheat were compared for 16 soils collected throughout the agricultural region. Ten of the 16 soils were also used to compare the P requirements of canola and wheat. The P was applied as powdered single superphosphate, and yield of dried shoots of 42-day-old plants was measured. The amount of P required to produce 90% of the maximum yield of dried shoots (PR90 values) was used to compare the P requirements of the species. To produce 90% of the maximum yield, field pea required less P than wheat in 5 soils, similar P in 2 soils, and more P in 9 soils. Canola required less P than wheat in all 10 soils. We conclude the P requirements of field pea or canola relative to wheat depend on a complex interaction between plant and soil, particularly for field pea relative to wheat. Per unit of applied P, the P concentration in dried shoots decreased in the order canola > wheat > field pea, indicating the order in which plant roots of the 3 species were able to access P from soil.

Tyrimų tikslas – nustatyti dirvožemyje biogeninių elementų pokyčius ekologinės žemdirbystės sistemose tręšimui naudojant mėšlą, raudonųjų dobilų biomasę žaliajai trąšai ir jų derinius, o tausojamosiose – mitybos elementų kiekį papildant mineralinėmis trąšomis. Tyrimai atlikti Lietuvos agrarinių ir miškų mokslų centro (LAMMC) Joniškėlio bandymų stotyje 2006–2013  m. sunkaus priemolio giliau karbonatingame giliau glėjiškame rudžemyje (RDg4-k2), <i>Endocalcari-Endohypogleyic Cambisol</i> (<i>CMg-n-w-can</i>), kuriam būdingas mažas fosforingumas ir vidutinis arba didelis kalingumas. Sėjomainos rotacija: paprastasis miežis (<i>Hordeum vulgare</i> L.) + įs. → raudonasis dobilas (<i>Trifolium pratense</i> L.) → paprastasis kvietys (<i>Triticum aestivum</i> L.) → sėjamasis žirnis (<i>Pisum sativum</i> L.). Nustatyta, kad skirtingo humusingumo dirvožemyje, trąšai naudojant raudonųjų dobilų masę, mėšlą 40 Mg kg<sup>–1</sup> ar jų derinius po pirmosios 4 laukų rotacijos dirvožemio fosforingumas išliko artimas buvusiam, o po antrosios – nustatytas ženklus sumažėjimas. Tai rodo, kad panaudotų agropriemonių neužteko stabiliam dirvožemio fosforingumui palaikyti. Kalio kiekio neigiami pokyčiai nu­statyti ekologinėje žemdirbystės sistemoje, kurioje trąšai naudota raudonųjų dobilų masė. Tręšimas mėšlu turėjo tendenciją didinti jo kiekį dirvožemyje.

The presence of legumin-like constituents within the globulin fractions of wheat (Triticum aestivum), rye (Secale cereale) and corn (maize, Zea mays) was demonstrated. Two-dimensional analysis of wheat globulins in the presence and absence of a reducing agent revealed the existence of reducible approximately 60 kDa polypeptides. Western-blot analysis with 125I-labelled antibodies raised against the oat (Avena sativa) 12S globulin holoprotein or its alpha-subunits demonstrated, firstly, the immunological homology between the alpha- and beta-subunits of pea (Pisum sativum) legumin and oat 12S globulin, and secondly, the similar occurrence in wheat of antigenically homologous approximately 20kDa and approximately 40 kDa polypeptides that associate via disulphide linkage to form approximately 60 kDa dimers. Western blotting also showed the presence of disulphide-linked approximately 20 kDa and approximately 40 kDa legumin-like subunits within the globulin fractions of rye and corn.

Experiments were conducted to determine the effect of Sea Crop (SC 16) and Ergostim on the yield and nutrient composition of a few crops. Studies conducted under greenhouse and field conditions showed that the yields of wheat (Triticum aestivum L.) and peas (Pisum sativum L.) were not affected by the addition of SC16. The nitrogen (N) and sulfur (S) concentrations of the two crops were not affected by SC 16, except in the control and SC 16 treatment only where the increases were likely due to a concentration effect, since these two treatments had lower yields. Boron (B) and molybdenum (Mo) concentrations in the plants were significantly affected by B and Mo applications, but not by SC 16. A greenhouse study showed that the yields of alfalfa (Medicago sativa L.) and wheat were not affected by the addition of Ergostim. The addition of Ergostim did not affect the N or S concentration of wheat or three cuts of alfalfa.

The influence of soil-applied phosphorus on the phytotoxicity of soil-applied 3-amino-s-triazole (amitrole) and 3-(3,4-dichlorophenyl)-1,1-dimethylurea (diuron) for corn(Zea maysL.), ryegrass(Lolium multiflorumL.), rye(Secale cerealeL.), snapbeans(Phaseolus vulgarisL.), soybeans(Glycine max(L.) Mers.), sorghum(Sorghum vulgarePers.), wheat(Triticum aestivumL.), cotton(Gossypium hirsutumL.), peanuts(Arachis hypogaeaL.), and peas(Pisum sativumL.) was studied under greenhouse conditions. All species except cotton and peanuts indicated an amitrole-phosphorus interaction. Greater phytotoxicity was found for a given rate of amitrole as the soil phosphorus level was increased. A diuron-phosphorus interaction was observed for cotton and soybeans only.
