Effect of Rice Cultivars and Herbicidal Combinations Integrations on Weeds and Yield of Broadcast-Seeded Rice Productivity and Economic Feasibility

Abstract

Nowadays there was an attitude from farmers to grow broadcasted seeded rice as an alternative to transplanted rice due to the scarce and costly labors in rice transplanting, but broadcasted seeded rice suffer severely from weed competition where sometimes the yield was sometimes completely lost. Finding good weed control package in rice fields which consist from. Main findings show that the use of old and newly herbicide molecules combination can succeed for sowing and rice broadcasted rice without problem. For these reasons two field experiments were conducted in split plot design were carried out at the Farm of Sakha Agricultural Research Station, Sakha, Kafrelshiekh , Governorate, Egypt during 2016 and 2017 summer seasons to evaluate the effect of two rice cultivars allocated as in the main plots two broadcasted seeded rice cultivars Sakha 106 and Sakha 104 were used in this study and thirteen weed control treatments which were the use of single herbicides or their combinations assigned in sub plots namely;
