“…The effect of tillage on grain legume yield (Lafond et al 1992) and the influence of including grain legumes in the rotation on the yield of succeeding cereal crops (Bremer et al 1988;Stevenson et al 1995) have been well documented. Little information is available, however, on the effects of tillage and preceding crops on nitrogen (N) fixation by grain legumes.…”

“…Reduced levels of soil nitrate in soils under zero tillage management were associated with increased Nfixation by soybean (Glycine max L.) (Hughes and Herridge 1989;Wheatley et al 1992). Zero tillage often results in increased soil water content (Lafond et al 1992), and this reduced water stress may increase N-fixation in grain legumes (Bennet and Albretch 1984). Bremer et al (1988) reported reduced N-fixation with a decline in water use by lentil (Lens culinaris Medikus).…”

. 1997. The influence of tillage and crop rotation on nitrogen fixation in lentil and pea. Can. J. Plant . Direct seeding into standing stubble and crop diversification are two practices that are becoming widely adopted in western Canada. This study was conducted to determine: i) the influence of zero and conventional tillage on N-fixation in lentil (Lens culinaris Medikus) and pea (Pisum sativum L.), and ii) the effect of cropping history on N-fixation in lentil. Data were obtained from a crop rotation experiment being conducted on a silty clay soil in east-central Saskatchewan, which included six cereal-oilseed-cereal-pulse rotations, each managed using zero and conventional tillage practices. The finding showed that N-fixation was 10% higher by lentil and 31% higher by pea when grown using zero tillage as compared to conventional tillage practices. On average, lentil grown in highly diversified crop rotations fixed 12% more nitrogen than when grown in less diversified crop rotations. Le semis direct sur chaume sur pied et la diversification des cultures sont deux pratiques en extension rapide dans l'ouest du Canada. L'objet de nos recherches était de déterminer 1) l'influence de la culture sans labour et du travail du sol classique sur la fixation azotée chez la lentille (Lens culinaris Medikus) et chez le pois (Pisum sativum L.) et 2) l'effet des antécédents culturaux sur la fixation azotée chez la lentille. Les données provenaient d'une expérience de rotation des cultures conduites sur argile limoneuse dans le centreest de la Saskatchewan, comprenant six assolements céréales-oléagineux, céréales-légumes secs, chacun conduit en régime de culture sans labour et en régime de travail classique du sol. Nos observations montrent que la fixation N était 10 % supérieure chez la lentille et 31 % supérieure chez le pois en régime de semis direct qu'avec les pratiques classiques de travail du sol. En moyenne, la lentille insérée dans des rotations fortement diversifiées fixait 12 % plus d'azote que dans des rotations plus simples.

“…In Saskatchewan, the soil moisture content in the 0-60 cm profile was found to be 9% higher in no-till plots than in those under conventional tillage (Lafond et al 1992). Our research from Ririe indicates that shallow subsoiling has the potential to increase soil moisture availability at depths between 61 and 90 cm of the soil profile at anthesis, when precipitation is available to recharge the upper 90 cm.…”

Abstract:The influence of shallow (20 cm deep) subsoil tillage on cereals planted with a no-till planter was investigated for 3 years at two locations in southeastern Idaho. Among Fusarium spp., F. culmorum was the primary fungus isolated from diffuse brown-black root lesions in the wetter location (Ririe), while F. semitectum, F. reticulatum, F. equiseti, and F. acuminatum were the dominant species isolated at the drier location (Arbon Valley). Increased yields resulting from methyl bromide fumigation indicated that biological factors were limiting the yield. However, subsoiling did not influence nematode populations or fungal root rots. The primary parasitic nematode found at both locations was Pratylenchus neglectus. Subsoiling had a tendency to increase soil moisture at depths between 61 and 90 cm, to increase organic matter, and to decrease nitrogen. Yield increased by 8% or more with subsoil tillage at both locations the first year. Yield increases were not significant in other years, when moisture was particularly limiting or abundant. Subsoiling may prove favorable for cereals planted in a soil-conservation tillage system, but the risk of fungal root rots may increase with such a practice. Additional study is warranted, as subsoil-tillage practices may increase yield and desirable soil parameters without compromising the benefits associated with cereal production in a soil-conservation tillage system. Key words: Fusarium spp., fusarium root rot, direct seeding, dryland, subsoiling, no till, zero tillage.Résumé : L'effet d'un sous-solage superficiel (20 cm de profondeur) sur des céréales plantées avec un planteur pour le semis direct a été étudié pendant 3 ans à deux sites du sud-est de l'Idaho. Parmi les espèces du Fusarium, le F. culmorum a été le principal champignon isolé de lésions racinaires floues brun noir au site le plus humide (Ririe), alors que les F. semitectum, F. reticulatum, F. equiseti et F. acuminatum ont été les espèces dominantes isolées du site le plus sec (vallée d'Arbon). Des augmentations de rendement résultant de fumigation au bromure de méthyle ont révélé que des facteurs biologiques limitaient les rendements. Par contre, le sous-solage n'a pas eu d'effet sur les populations de nématodes ou sur les pourritures racinaires fongiques. Le Pratylenchus neglectus fut le principal nématode parasite retrouvé aux deux sites. Le sous-solage avait tendance à augmenter la teneur en eau du sol aux profondeurs entre 61 et 90 cm, à augmenter la matière organique et à diminuer l'azote. Avec le sous-solage, les rendements ont augmenté de 8% ou plus aux deux sites au cours de la première année. Lors des autres années, les augmentations de rendement n'étaient pas significatives lorsque l'eau était particulièrement limitée ou abondante. Le sous-solage peut s'avérer profitable pour les céréales plantées dans un système de conservation des sols, mais une telle pratique pourrait accroître le risque de pourriture racinaire fongique. Des études supplémentaires sont souhaitables puisque les pratiques de so...

Lafond et al (1992) reported that NT increase the water storage capacity of the soil and increase the available water for crop growth. Maintenance of stubble on the surface enhanced the capacity to store soil water reserves significantly under NT but not under CT.…”

A field study was conducted to evaluate moisture storage in soil profile under four tillage-residue management practices namely conventional tillage, no-tillage without residue, no-tillage with residue and deep tillage along with three irrigation regime based on IW/PAN-E ratio 1.2, 0.9 and 0.6 in maize with three replications in split plot design. Significant differences were observed in steady state infiltration rate and cumulative infiltration among different land management practices with maximum value in deep tillage (4.9 cm hr -1 and 33.1 cm) followed by no tillage with residue (4.1cm hr -1 and 28.6 cm), no tillage without residue (4.0 cm hr -1 and 23.0 cm) and conventional tillage (2.8 cm hr -1 and 19.4 cm), respectively. The highest mean weight diameter and water stable aggregates were found under no tillage with residue (0.64 mm and 49.7%) and lowest under deep tillage (0.3 mm and 21.8%), respectively. Higher volumetric soil water content and soil profile moisture storage were recorded under no tillage with residue at different days after sowing. Among different tillage-residue management practices, maximum leaf area index and relative leaf water content were observed in no-tillage with residue. Under moisture stress conditions, no-tillage with residue retention was suitable land management option for reducing evaporation losses and enhancing moisture storage in the soil profile.
