Abstract

In order to study on the effect of PLANT RESIDUE management methods, Azona and duck on WEED control, YIELD AND HARVEST INDEX of native Tarom variety rice ratoon, a field experiment was conducted in factorial split based on randomized Complete block design (RCBD) with three replications. At ratoon crop, management of PLANT RESIDUE treatment (cutting at base, common regional harvest and lock-lodging methods) was main factor and Azona at two levels (with and without) and duck also at two levels (with and without) were subfactors. Results revealed that lock-lodging and common regional harvest methods had highest and lowest WEED Population respectively. Number, mean height and mean dry weight of WEEDs were also decreased by Azona and duck. In this study, WEEDs Cyperus difformis, Echinochola crus-gali and Typa latifoli caused highest damage to ratoon crop. Maximum YIELD AND HARVEST INDEX were obtained in lock-lodging technology due to increased total number of produced tillers, number of panicle per square meter and total number of spike lets per spike. Duck was also increased grain yield due to mentioned parameters and high thousand grain weight. In this research, maximum rate of harvest index was obtained in integration of lock lodging method with Azona and duck.
