Abstract
A field experiment was conducted on medium black calcareous clayey soil at Pulses Research Station, Junagadh Agricultural University, Junagadh during three seasons of 2011–12, 2012–13 and 2014–15 to study the efficacy of pre-and post-emergence herbicides in Kharif blackgram (cv. GU-1). The quizalofop- ethyl 40 g/ha as post-emergence (PoE) at 20 days after seeding (DAS) + hand weeding (HW) at 40 days after seeding (DAS) and pendimethalin 900 g/ha as pre-emergence (PE) + hand weeding (HW) at 40 DAS were found equally effective to the weed-free check in controlling weeds and improving growth and yield attributes and ultimately seed yield (1.14 and 1.13 t/ha) and straw yield (1.26 and 1.33 t/ha) of blackgram. These treatments also recorded higher weed control efficiency (65.3 - 63.1%), herbicide efficiency index (81.1 - 82.3%), lower weed index (9.1 - 9.7%) and minimum weed dry biomass (273.9 - 291.7 kg/ha) and higher net returns (‘ 21,230 and ‘ 21,162/ha). Integrated weed management practices with herbicides as a component were found effective and economical under south Saurashtra agro-climatic conditions of Gujarat.
