Jalali, A. Changes in weed seed banks and the potato yield as affected by different amounts of nitrogen and crop residue. International Journal of Plant Production , 7 1 , H Jalali. International Journal of Plant Production , 7, 1, , International Journal of Plant Production , ; 7 1 : Toggle navigation. Numbers of weed species in seed bank, aboveground, and both seed bank and aboveground were 1, 2 and 8 respectively. Amaranthus retroflexus L. Weed seed bank was significantly lower in both N rates than control in the both years with no significant difference between the rates. Weeds biomass with increased use of nitrogen fertilizer increased. In 25 and 50 percent of crop residue treatments, weed seed density was greater than control. The results showed that management of nitrogen fertilizer application and weed control by applying crop residue crops in rotation will change. How to cite.

Potato Solanum tuberosum L. The field experiment was conducted as split plots in completely random block designs in three replicationsby two tape and furrow irrigation methods in central of Iran. Experimental treatments included two series of weed-crop competition different temporal treatments in which the first series involved elimination of weed since emergence time to 20, 30, 40, 50 and 60 days after emergence and then weed presence and their competition to potato Marphona cultivar until season late. The second ones involved weed-crop competition since emergence to 20, 30, 40, 50 and 60 days after emergence and then weed elimination until end of season. Additionally, two control treatments involved weed-less and weed presence control during growing season were considered. Results indicated that in both irrigation methods, as interference duration increased, weed dry weight increased. Tuber yield and size reduced as weed interference period was increased. End of this period in furrow and tape irrigation methods was occurred at growing day degree GDD equals to 59 days and growing day degree GDD equals to 50 days after potato emergence respectively.
