“…Seed placement and soil conditions created by planting equipment ideally should optimize soil conditions around the seed. Gaultney et al (1982) observed a corn yield reduction of over 50% in Indiana during relatively wet years in severely compacted plots. In Iowa, significantly higher corn yield was produced when equipment used applied no more than 20-kPa (3-psi) surface pressure as compared to 110 kPa (16 psi) surface pressure in a 4-year study (Erbach et al, 1991).…”

“…Par rapport aux parcelles labourées, la succession des labours (manuel et mécanisé) a contribué à l'amélioration sensible de la fertilité des sols et par conséquent celle du rendement du riz. En effet, selon les travaux de Gaultney et al, (1982), plus les labours se succèdent sur un sol, plus ils rendent meuble sa structure ce qui permet un gain de rendement de 25% lorsque l'itinéraire technique est respecté.…”

The effects of mechanized plowing with power tiller and rotavator and that of the succession of production campaigns on the nutritive status of soil and the rice yield in pluvial system were studied in the low land of Dokomey in South of Benin. The methodological approach is based on field trials conducted during three successive production campaigns from 2014 to 2016 according to a split plot design with one factor (plowing).. Sampling and analysis of the physical and chemical soils' parameters were done at the beginning and end of each campaign and also the weighing of harvested paddy. Results showed that the fertility of the plots which received mechanized plowing and that of their yields increased noticeably during each campaign and along all the campaigns than those which received manual plowing. For example, from campaign 1 to 3, the yields under mechanized plowing increased respectively of 35%, 37% and 39% more than those obtained under manual plowing. The same report was obtained for soils parameters where the contents of organic matters (OM), nitrogen (N), ratio C/N, cationic exchange capacity, assimilable phosphorus (Pass) and clay increased respectively of 31,63% ; 11,77% ; 13,39% ; 10,28% ; 6,03% et 3,74%.Moreover, the correlations study between yield and nutritive status of soil showed likewise a high dependence between those parameters and the obtained yields. This dependence was highly significant at the level of 0.1% for th mechanized plowing.EuropeanScientific Journal October 2017 edition Vol.13, No.30 ISSN: 1857 -7881 (Print) e -ISSN 1857-7431 342Keywords: Fertility, nitrogen, organic matters, ratio C/N, clay, power tillerrotavator RésuméLes effets du labour mécanisé avec l'attelage motoculteur-rotavator ainsi que ceux de sa succession sur le statut nutritif du sol et sur le rendement du riz en régime pluvial ont été étudiés dans le bas-fond de Dokomey au Sud-Bénin. L'approche méthodologique utilisée est basée sur des essais agronomiques conduits pendant trois campagnes successives de production de 2014 à 2016 selon un dispositif en split-plot à un facteur (labour). Il a été procédé à des analyses des paramètres physico-chimiques du sol avant le démarrage et à la fin de chaque campagne ainsi qu'à la pesée des récoltes du riz paddy. Les résultats ont montré que la fertilité des parcelles en labour mécanisé ont des rendements qui ont sensiblement augmenté au cours de chaque campagne que ceux obtenus en labour manuel. Par exemple, de la campagne 1 à 3, les rendements en labour mécanisé ont respectivement augmenté de 35, 37 et 39% de plus que ceux obtenus en labour manuel. De même les teneurs des paramètres du sol que sont : matières organiques, azote, rapport C/N, capacité d'échange cationique, phosphore assimilable et argile ont respectivement augmenté de 31,63% ; 11,77% ; 13,39% ; 10,28% ; 6,03% et 3,74%. En outre, l'étude des corrélations entre le rendement et le statut nutritif du sol a également montré qu'il y a une forte dépendance entre ces paramètres et les rendements obtenus. Cett...

“…Soil compaction reduces crop yields and causes environmental damage (Alblas et al, 1994;Barber, 1994;Box and Langdale, 1984;Gaultney et al, 1982;Reeder and Wood, 1991;Schuler and Kostichka, 1994;Schuler and Lowery, 1984;Schwab et al, 2002;Tupper et al, 1987). Many studies have documented that soil compaction increases runoff and soil erosion (Voorhees et al, 1979) and reduces rooting volume, plant size, infiltration, water storage (Craul, 1994;Ess et al, 1998;Gayle et al, 1992;Unger and Kaspar, 1994).…”
