“…Deficiency of B was suspected to be responsible for these conditions because the symptoms match B deficiency symptoms (Grant & Bailey, 1993). In an earlier study on the Parkland region soils of Saskatchewan, B fertilization was observed to enhance rapeseed yield in a greenhouse experiment but its effect was not consistent in field experiments (Nuttall et al, 1987). In another field study in Saskatchewan, Canada, application of B fertilizer did not have any consistent influence on seed yield increase of canola, grown on soils ranging between 0.11 to 0.82 mg plant-available B kg -1 (Malhi et al, 2003).…”

“…Therefore, extreme care is needed to apply the correct dose of B fertilizer and to distribute it uniformly. Boron application rates generally range from 0.25 to 3.0 kg B ha -1 , depending on crop requirement and the method of application (Arora et al, 1985;Nuttall et al, 1987;Patil et al, 1987;Sakal et al, 1988;Ali & Monoranjan, 1989;Dwivedi et al, 1990;Sinha et al, 1991;Mortvedt & Woodruff, 1993). Higher rates are required for broadcast applications than for banded soil applications or foliar sprays.…”

“…Sulphur deficiency may reduce acetyl-CoA carboxylase activity and oil biosynthesis may be limited by a lack of acetyl-CoA carboxylation . Sulphur fertilization can increase protein content in canola (Nuttall et al 1987; although in other studies, S did not influence protein content (Asare and Scarisbuick 1995). The effect of S on protein may depend on the N:S ratio .…”

. 2003. Sulphur fertilizer and tillage effects on canola seed quality in the Black soil zone of western Canada. Can. J. Plant Sci. 83: [745][746][747][748][749][750][751][752][753][754][755][756][757][758]. Field studies in Manitoba, Saskatchewan and Alberta over 3 yr evaluated immediate and residual effects of source, timing and placement of sulphur (S) fertilizers on canola quality under reduced (RT) and conventional tillage (CT). Oil concentration of canola seed increased and chlorophyll content decreased with application of plant-available forms of S fertilizer if soils were deficient in available sulphate-S. Therefore, canola seed quality was improved by correction of S deficiencies. The magnitude and consistency of fertilizer effects reflected the sulphate availability of the fertilizer source applied, with ammonium sulphate having a greater effect than the bentonite-elemental S product, Tiger 90 ® , in the year of application. Effects on seed N concentration were inconsistent, but decreases in seed N concentration occasionally occurred with correction of an S deficiency, reflecting an inverse relationship between seed yield or seed oil concentration and seed N concentration. Seed S concentration generally increased with increases in available sulphur. Application of ammonium sulphate in the preceding wheat crop provided residual sulphate-S for canola, leading to increased oil and seed S concentration, and decreased chlorophyll and seed N concentration. Tillage system had little influence on canola quality, with RT occasionally reducing oil concentration and increasing chlorophyll and seed N content. The response of seed quality to S fertilization was similar under CT and RT. Sulphate-S sources consistently improved canola quality on S-deficient fields. Trois années durant, des études sur le terrain poursuivies au Manitoba, en Saskatchewan et en Alberta ont servi à évaluer les effets immédiats et résiduels de la source, du moment d'application et de la localisation des engrais soufrés (S) sur la qualité du canola cultivé avec et sans travail du sol. L'application d'engrais S assimilable par la plante augmente la quantité d'huile dans la graine et diminue celle de chlorophylle quand le sol est carencé en sulfates assimilables. Corriger cette carence améliore donc la qualité des graines. L'ampleur et l'uniformité des effets de l'engrais dépen-dent du potentiel d'assimilation du sulfate l'année de l'application, le sulfate d'ammonium étant plus efficace que Tiger 90 ® , engrais composé de S élémentaire et de bentonite. L'engrais n'agit pas de manière uniforme sur la concentration de N dans la graine, mais il arrive que cette dernière diminue quand on corrige la carence en S, signe que le rendement grainier ou la concentration de la graine en huile est inversement relié à la quantité de N dans la graine. En général, la concentration de la graine en S s'accroît avec la quantité de soufre disponible. L'application de sulfate d'ammonium à la culture antérieure de blé laisse des résidus de sulfate qu'utilise le ca...

“…A sufficient amount of S in combination with N on Sdeficient soils can increase seed protein concentration (Finlayson et al 1970;Nuttall et al 1987). However, application of N alone without S fertilizer on S-deficient soils can result in accumulation of amino acids in seed, as a proper N:S ratio is required for proper protein synthesis.…”

. 2005. A review of sulphur fertilizer management for optimum yield and quality of canola in the Canadian Great Plains. Can. J. Plant Sci. 85: 297-307. In the Parkland region of the Canadian prairies, Canola (Brassica napus L. or Brassica rapa L.) is an important cash crop. Canola has a high requirement for sulphur (S). However, many soils in this region are deficient or potentially deficient in plant-available S for optimum canola seed yield. Application of sulphate-S at about 15-30 kg S ha -1 is usually sufficient to prevent S deficiency in canola on most of the S-deficient soils. Application of sulphate-S to canola at seeding time gives the highest increase in yield and S uptake. Deficiencies of S in canola plants can be prevented and/or corrected and seed yield improved with the use of sulphate-S fertilizers in the growing season. Application of sulphate-S at bolting can substantially restore seed yield, while an application at early flowering can moderately correct S deficiency damage. Side-banding is the most effective way to apply sulphate-S fertilizers to produce maximum seed yield and to prevent any damage to canola seedlings from seed-row placement. In relatively moist areas, broadcast-incorporation methods can produce seed yield similar to side-banding in most years.Elemental S fertilizers were not effective in increasing seed yield in the year of application, and were generally less effective than sulphate-S fertilizer even after multiyear annual applications, especially when applied in spring. Autumn-applied elemental S was more effective than spring-applied elemental S. Banding delayed availability of elemental S as compared to broadcast application. Use of granular elemental S products is not reliable for optimum seed yield of canola under Canadian prairie conditions on S-deficient soils, particularly in the initial year and with spring application or band placement. Elemental S fertilizers may have a role to maintain or build-up sulphate-S levels in soils marginally low in S where residual benefits are desirable, but management decisions should consider both immediate and long-term effects of S fertilizer on seed yield, seed quality and economics. The findings suggest the need of future research to increase dispersion and distribution of S particles from granules for faster oxidation of elemental S in soil, and to develop elemental S fertilizer products/formulations that can be used on a commercial scale to prevent and/or correct S deficiency in the growing season to optimize seed yield and quality of canola. Research is also required to determine the long-term effects of balanced application of S with other nutrients on soil quality, accumulation and distribution of nitrate-N, sulphate-S and other nutrients in the soil profile, efficiency of nutrient, water and energy use, and crop diseases. More research should be conducted in relation to soil/plant tissue testing issues for optimum seed yield and quality of canola.Key words: Balanced fertilization, canola, elemental S fertilizers, method of ap...
