Summary
Effects of reduced tillage, fertilization and green manures on the weeds and crop yields in a cereal-legume crop rotation under organic farming. On 2011, we established a long-term experiment to evaluate the effects of reduced tillage (chisel vs mouldboard plough), fertilization with semicomposted manure and sowing of green manures before spring crops, on the crop yields and weed abundance in a 5-year rotation (spelt, chickpea, wheat, lentil and spelt). After five years, there was not noticeable increment in weed abundance or richness. Reduced tillage caused a significant increase of weeds compared with mouldboard plough, but it this increase did not cause significant yield loss in cereal crops compared with mouldboard plough. Green manures exerted a strong weed suppression, although this effect did not persist on the subsequent (legume) crop.
Entre 2011 y 2016 se realizó un experimento para evaluar el efecto del laboreo mínimo (chisel) respecto a arado de vertedera, de la fertilización con estiércol y de la siembra de abonos verdes antes de los cultivos de primavera, sobre los rendimientos del cultivo y la abundancia de las malas hierbas, en una rotación de 5 años (espelta, garbanzo,
trigo, lenteja y espelta). El laboreo mínimo provocó un aumento significativo de las arvenses pero sin conllevar pérdidas significativas en los rendimientos de los cereales respecto a los rendimientos con el arado de vertedera. El abono verde ejerció un fuerte control sobre las malas hierbas, aunque este efecto no persistió durante el cultivo de la leguminosa inmediatamente posterior.
