An experiment was conducted to examine the effects of different tillage systems and fertilization on quantitative and qualitative characteristics of cumin as split randomized complete block design with three replicates in Delfan during 2016. Main plot included three different tillage system; 1( conventional (mold board plough, chisel plough and disk), 2 (minimum tillage (chisel plough and disk) and 3( zero tillage (disk) and subplots comprised eight different combinations of organic and chemical fertilizer; 1) control, i.e. without any dose of manure and fertilizers, 2) 25 kg N ha-1, 3) 10 ton vermicompost ha-1, 4) 20 ton cow manure ha-1, 5) 20 ton municipal solid waste compost ha-1, 6) 50 percent dose of chemical fertilizer (N) + 50 percent vermicompost, 7) 50 percent dose of chemical fertilizer (N) + 50 percent cow manure and 8) 50 percent dose of chemical fertilizer (N) + 50 percent compost. Results indicated that the highest grain yield (81.53 g/m-2) and biological yield (210.41 g/m-2) achieved in minimum tillage and application of cow manure, while the least quantities of these parameters was observed in zero tillage and control. In addition, the greatest essential oil percentage and yield attained in minimum tillage and application of 10 ton vermicompost, which was 25 and 28 percent greater than control. The results suggested that to improve the quantitative and qualitative characteristics of cumin application of manure and vermicompost along with minimum tillage is recommended.

In order to investigate distribution status of heavy metals in cropping systems of water logging and dry farming, an experiment was conducted as split-plot arrangement based on randomized complete block design with three replications in research field of Sari Agricultural Science and Natural Resources University. A paddy-soil considered for water logging system and the planted field with vegetables considered for dry farming system. Main plot (fertilizer treatments added to soil) included five treatments: 20 and 40 ton.ha-1 compost, 20 and 40 ton.ha-1 sewage sludge and control. Also, sub factor (application years) consisted three treatments comprised: one, two and three years fertilization. The results showed that in water logging system sewage sludge treatments had more influence on heavy metals accumulation in soil while, compost treatments had more influence than sewage sludge treatments in dry farming system. Also, in paddy soil the enhancement percent of available form compared to control treatment was much more than dry farming system.
