چکیده
in order to effect of different mulch materials and optimal chemical, organic and biological fertilizer management on ecological agriculture characteristics in common purslane (portulaca oleracea l.) in khuzestan conditions, a filed experiment was conducted at experimental field of ramin agriculture and natural resources university in ahwaz, south-western of iran, during 2010- 2011 growing season. treatments were arranged as a factorial-spilit experiment in a randomized complete block design with three replications. fertilizer treatments at five system (s1: chemical fertility systems, s2: chemical fertility systems+ biofetilizers, s3: chicken manure, s4: chicken manure + biofetilizers and s5: cow manure + biofetilizers) and three mulch materials (m1: without mulch, m2: wheat straw, m3: black plastic). in first cutting, the result indicated that application chicken manure and chicken manure + biofertilizers was increased the plant dry weight, plant height and chlorophyll content, in second and third cutting, chemical fertility system+ biofetilizers(s2) had the highest the plant dry weight, plant height and chlorophyll content. the black plastic in first and second cutting was the highest plant dry, the plant height and chlorophyll content but this mulch was not a good production in third cutting. the result of the experiment revealed that the plant dry weight was higher in third harvest. this case showed probability of application of mulch and organic manures and biofetilizers with chemical manure in common purslane for sustainable and healthy production.
