Abstract
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
with twelve treatments and replicated thrice using blackgram MDU 1 as a test
variety. Among the weed control treatments, application of H2O2 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.
Key words : Blackgram, Hydrogen peroxide, Zinc oxide, Silver Nanoparticles, Pendimethalin and Weed
management.
