چکیده
Radiations and radioisotopes are used in agricultural research to induce genetic variability in crop plants to develop improved varieties, to manage insect pests, monitor fate and persistence of pesticides, to study fertilizer use efficiency and plant micronutrient uptake and also to preserve agricultural produce. Use of radiation and radioisotopes in agriculture is one of the most important fields of peaceful applications of atomic energy for societal benefit and BARC has contributed significantly in this area especially in the development of new mutant crop varieties and food irradiation for enhancing food safety, reduce post harvest losses, enhance shelf life and as a quarantine measure for enabling international trade in food and agricultural commodities.

Changes in weed seed banks and the potato yield as affected by different amounts of nitrogen and crop residue
In order to evaluate the impact of crop residues (zero, 25 and 50%) and nitrogen (zero, 125 and 250 kg ha) on weed seed bank and potato yield, two-years research was conducted as a split plot arranged in randomized complete block design in Rozveh Agriculture Research Station, Freidan-Esfahan. Numbers of weed species in seed bank, aboveground, and both seed bank and aboveground were 1, 2 and...

متن کاملIndividual and interactive effects of crop type and management on weed and seed bank composition in an organic rotation
We investigated the effects of organic and conventional pest and fertility management on weed cover and the seed bank community in an organic rotation. The study was conducted during the 4th and 5th years of an organic rotation on part of a long term organic-conventional comparison trial. Results showed that although crop type (potato vs. cabbage) in a single year significantly affected wee...
متن کاملتأثیر تناوب زراعی، کاربرد کود شیمیایی و علفکش بر کنترل علفهای هرز چاودار زمستانه
The recent years' problems of herbicide use have led a growing number of researchers to seek alternative methods that are less reliant on herbicides. This research was conducted to determine the effect of long-term crop rotation, mineral fertilizer and herbicide on the weed infestation and grain yield of winter rye during 2004 and 2005 at the long-term experimental site of the University of Tim...
