Management of Weed Seed Bank Using Nanoparticles in Combination with Pendimethalin and Hydrogen Peroxide in Irrigated Blackgram (Vigna mungo L.)

摘要

Field experiments were carried at Agricultural College and Research Institute, Madurai, Tamil Nadu Agricultural University, Tamil Nadu, during kharif and rabi seasons of 2017 - 2018, to study the effect of nanoparticles in combination with pendimethalin and hydrogen peroxide on weeds and blackgram crop. The experiments were laid out in randomized block design 3 with twelve treatments and replicated thrice using blackgram MDU 1 as a test 8 variety. Among the weed control treatments, application of H202 followed by Pendimethalin + Ag nanoparticles recorded lower weed index, total weed dry weight, total weed density and with higher weed control efficiency and yield of black gram in both the seasons. It was comparable with the application of pendimethalin (0.75 kg a.i. ha~(-1)) + hand weeding at 35 DAS.
