The effect of plant residual on establishment of crops

Abstract

In order to evaluation of plant residual on establishment of crops an experiment was conducted during 2006- 2007 in Sharood Universiy of Technology in Iran. The experiment was as factorial in Completely Randomized Design with 4 replications. The residual of Triticum aestivum, Beta vulgaris, Zea mays and Brassica napus and distilled water as check were tested on themselves and other crops. The results showed residual of crops had different effect on growth of themselves and other crops. Germination percentage, speed of germination, root dry weight, stem dry eight, root length, stem length, root/shoot ratio and plant growth traits were significantly affected by residual of Beta vulgaris, Zea mays, Triticum aestivum and Brassica napus respectively.
