The objective of this work was to measure the effects of different tillage methods on weeds population in second crop corn. The field experiment was conducted at the research area of Dicle University in 2014, Diyarbakır province, southeastern part of Turkey. The treatment was lay out at the randomized complete blocks design with three times replication. In this study, different six tillage method were applied (one conventional tillage (CT) – four conservation tillage (RT) and no-till (NT)). According to results, there were found significant difference among treatments. The lowest values of weeds were recorded in the CT, while the highest values of weeds were noted in RT1and NT tillage methods. There was found more density the speices of Xanthium strumarium subsp., Solanum nigrum L., Euphorbia helioscopia L., Convolvulus arvensis L. and Sorghum halepense (L.) Pers. than other weed species .As a result, we can consider reduce tillage methods for mechanical weed control for corn production.

The paper researches the influence of two tillage systems – conventional tillage and strip tillage on soil nutrients content, soil acidity and microbiological activity over a reseаrch period of four year – from 2014 to 2017 included. The test are carried out on the same fields in Northeastern Bulgaria. Soil nutrient testing can help determine the necessary amount of fertilizers to be used on a specific field.

The aim of this study was to determine the effects of different tillage methods on weeds population in second crop soybean production. The experiment was conducted at the experimental area of Agrıcultural Faculty at Dicle University in 2014. The treatment was lay out at the randomized complete blocks design with three times replication. In this study, different six tillage method were applied (one conventional tillage (CT) – four conservation tillage (RT) and direct sowing (NT)). There were observed more density the species of Xanthium strumarium subsp., Solanum nigrum L., Euphorbia helioscopia L., Convolvulus arvensis L. and Sorghum halepense (L.) Pers in experimental area than other weed species. According to results, there were found significant difference between treatments. The lowest values of weeds were recorded in the conventional tillage methods (CT), while the highest values of weeds were noted in RT4 Tillage methods and NT. Therefore, conventional tillage method was beneficial and useful in reducing of weeds population on soybean crop.
