Efficient and Economical Weed Management in Summer Sesame (Sesamum indicum L.)

Abstract

Abstract

A field experiment was conducted during summer seasons 2010 to 2012 at Junagadh (Gujarat) to study the integrated weed management in sesame. Pendimethalin as pre-emergence, while imazethapyr and quizalofop-ethyl as post-emergence were tested alone and in integration with hand weeding and interculturing. The results revealed that quizalofop-ethyl 40 g ha^-1 as post-emergence (20–25 DAS) + HW & IC (45 DAS) and pendimethalin 450 g ha^-1 as pre-emergence + HW & IC (30 DAS) were found equally effective to the weed free check in controlling weeds and improving growth and yield attributes and ultimately seed yield (1213 and 1169 kg ha^-1) and stalk yield (2015 and 1852 kg ha^-1) of sesame. These treatments also recorded higher net returns (` 44066 and 42242 ha^-1) and B:C ratio (3.58 and 3.54), therefore, these integrated weed management practices could become effective and economical under south Saurashtra agro-climatic conditions of Gujarat.
