Modern soil tillage systems based on different tools than mouldboard plough have very often stronger weed occurrence, which can be a serious problem for achieving high yields. An obvious solution for weed suppression is a herbicide, whose improper use can deteriorate environment and lead toward serious ecological problems. In order to investigate the interaction between soil tillage and herbicide, trial was set up in Valpovo in seasons 2008/09 - 2010/11. Two soil tillage systems (CT-conventional tillage, based on mouldboard ploughing, and CH-chiselling and disk harrowing, without ploughing) and five herbicide treatments (NH-control, no herbicides; H10- recommended dose of Herbaflex (2 l ha-1); H05-half dose of Herbaflex; F10- recommended dose of Fox (1.5 l ha-1); and F05-half dose of Fox) were applied to winter wheat crops. Results showed similar effects of soil tillage on the winter wheat yield, whereas different herbicide dosages showed similar weed suppression and influence on winter wheat yield.

UNLABELLED Lymphadenopathy is defined as an abnormality in the size or character of lymph nodes, is caused by the invasion or propagation of either inflammatory cells or neoplastic cells into the node. Numerous factors, such as age, localization, size and consistency, present and previous pathological conditions are very important in order to define the future diagnostic and therapeutic course. OBJECTIVE The aim of this study was to determine the etiological and clinical characteristics oflymphadenopathy in children in the area of the Tuzla Canton. PATIENTS AND METHODS This retrospective-prospective study analyzed the medical records of the Department of Pediatrics in Tuzla of 334 patients in age from 0 to 14 years, in which the clinical signs of palpable lymph nodes of one or more regions was diagnosed in the period from January 1st 1998 to June 30th 2003. The anamnesis data, clinical findings, diagnostic procedures results, therapeutic approach and disease outcome etiology defined lymphadenopathy were analyzed. RESULTS Out of 334 children, localized lymphadenopathy have been verified in 230, and generalized in 104. Male/female ratio was 1:1.8. Final results of our study have shown the etiologies as following: Infectious etiologies, 79.34%, neoplastic 11.34%, and non-neoplastic 9.28%. In neoplastic etiologies, lymphoblastic leukemia has been the most often verified neoplastic disease (68.4%), not related to the age or sex of patient, and equally presented as localized and generalized lymphadenopathy. In this study lymphomas were presented by generalized lymphadenopathy. CONCLUSION The regional and generalized lymphadenopathy in children depends on their etiology and has significant prognostic value for the disease.
