Effect of soil solarization and chicken manure on germination and viability of field dodder (Cuscuta Camperstris)‎ seeds

Abstract EN

Field studies were conducted in Basrah reigon to investigate the effect of different durations (0-6wk) of solarization alone on scarified dodder seeds,and solarization with / with out chicken manure on non scarified seeds at various soil depths(0-20cin).

l:or both scarified and non scarified dodder seeds ,the effect of solarization periods on percent total seeds germination (PTSG ) was consistent only at 0 depth.At this depth most of the solarization effect on scarified dodder seeds occurred during the first lOd Where the reduction in PISG was 05% .Non scarified dodder seeds required 6wk of Solarization alon for significant reduction (69 %) in PTSG at Odepth.

Chicken manure redused the period of solarization from 6 to 2 wk for significant PTSG reduction
