Effect of Cropping Type, Land Covered with Wheat Residue and without Residue on Emergence Pattern of Seedling and Rhizome Sprouting Shoot of Sorghum halepense L. in Karaj Region

Pages

Abstract

 In order to survey TTern/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">emergence paTTern of seedling and ramet of Johnson grass (Sorghum halepense), an experiment was conducted in the research field of department of agriculture of Tehran University. Evaluations were performed in corn and potato' fields, and two fallow fields (with and without wheat residual that we say hereafter bare field). Johnsongrass seedlings and rhizome sprouting shoots were counted at one-week intervals throughout the season. Results indicated that in residual treatment, cumulative emergence of seedling of S. halepense reached to maximum amount in upper thermal time (1278 TT) in comparison with other treatments. Also in the field with residual, rate of emergence of seedlings per unit of thermal time was more (974 seedlings). In corn field required TT to reach 50% rhizome emergence was more than other treatments (1118 TT). The most cumulative emergence of seedling and rhizome shoot observed in bare soil treatment, was 1034 and 1541 seedlings, respectively. Emergence of seedlings quickly stoped under corn and potato canopy while emergence of rhizome shoots continued to the end of the season. The present study demonstrated that the emergence of Johnson grass seedlings is faster rhizomes in early season and thus early plowing at the beginning of season can be an effective practice to control its emergence.
