چکیده
The study aimed to determine the interference periods of weeds in cassava ‘IAC 90’ cultivated different cycles and cropping systems. An experiment was conducted period 2014/15 (1st cycle) another from pruning plants 2015/16 (2nd cycle). experimental design a randomized block with split-split plots four replicates. represented systems (conventional no-tillage) corresponded without coexistence (0, 25, 50, 75, 100, 125, 150, 175, 200 225 days after planting or - DAP/DAPr). In 1st cycle, there no interaction between and, therefore, based on acceptable losses 5% root starch yield 'IAC 90' cassava, PCPI estimated 20 212 DAP 14 214 DAP, respectively. 2nd CPPWI ranged 17 176 DAPr 30 216 obtained conventional method, While no-tillage, 18 198 9 218 yield, general, data indicate that weed management should be carried out more intensified way than no-tillage. addition, can avoid production.

Eubacterial communities in different soil macroaggregate environments and cropping systems
Different positions within soil macroaggregates, and macroaggregates of different sizes, have different chemical and physical properties which could affect microbial growth and interactions among taxa. The hypothesis that these soil aggregate fractions contain different eubacterial communities was tested using terminal restriction fragment length polymorphism (T-RFLP) of the 16S ribosomal gene....
