To evaluate the response of saffron to animal manure, and biological chemical fertilizer in an arid climate, experiment was performed as split plots based on a randomized complete blocks design with three replications during consecutive crop growth seasons (2015-2018) at Research Farm University Gonabad, Iran. The experimental treatments included application (60 t ha-1) non-application (control) manure main plot use biosulfur (5 kg ha-1), biophosphate (3 L nitroxin (150, 100, 100 ha-1 urea, triple superphosphate, potassium sulfate, respectively), no sub-plot. results showed highly significant quantitative traits which increased leaf, flower, corm indices by mean 15.1-35.7% than control. interaction effect fertilizers for weeds significant. There difference between biophosphorus most mentioned years. simultaneous these average about 60, 105, 135, 110, 165, 55% leaf dry weight, number flowers, fresh flower yield, stigma weed weight saffron, respectively compared or terms related so fertilizers, control, replacement size, bud per by, respectively, 35, 40% average. improved content crocin, picrocrocin, safranal stigma. best were obtained from although observed this treatment treatments. Overall, three-year show very high plant and, therefore, it is possible replace organic cultivation implement agriculture achieve acceptable qualitative yields areas similar location.

This study investigated potentially toxic elements (PTEs) pollution in groundwater across the Maros karst area. The quality was evaluated using three indexing methods, heavy metal index (HPI), evaluation (HMEI) and contamination (Cd). levels of PTEs were calculated to determine noncancer cancer risks residents through ingestion dermal adsorption. To obtain high-level accuracy risk estimation, a Monte Carlo simulation model sensitivity analysis performed. mean values rainy summer season followed order Cr > Pb Zn Cu Cu, respectively. high level exceeded permissible limit World Health Organization (WHO) Indonesian Standards. However, TDS, pH, EC temperature still accordance with WHO guidelines. geostatistical interpolation HPI, HMEI Cd revealed that around is low, particularly Tukamasea Leang-Leang village. Hazard lower than one, implying no possibility risk. results 95% confidence demonstrated children adults are at for developing due PTE exposure.

The degradation of water resources is related to anthropic actions such as rapid urbanization and industrial agricultural activities with inefficient land use occupation management. Water pollution caused by organic inorganic contaminants represents a current challenge for researchers humanity. One the techniques used remove pollutants from aquatic environments bioremediation, through metabolism living organisms, especially phytoremediation, plants decontamination agent. Aiming demonstrate mechanisms, solutions, perspectives regarding phytoremediation in environments, literature review was conducted, highlighting following subjects: heavy metals contaminants, evaluation resistance removal microorganisms biofilters artificial floating islands type. From research carried out, it can be concluded that alternatives macrophyte have proved an effective efficient alternative high potential including concomitantly microorganisms. There no mechanism well-defined specific absorption plants; however, some results indicate if there sporadic contamination indicators adsorption absorption, even low concentration watercourse moment evaluation. It necessary study bioremediation methods, tolerance, efficiencies each biological agent chosen. Within processes capacity metals, combined bioremediating microorganisms, biofilters, interesting perspective contaminants.
