Description Research article
A field experiment was conducted during 2015–16 and 2016–17 to assess the system productivity, energetics and
economics of weed management practices in soybean (Glycine max L.)-wheat (Triticum aestivum L.) cropping system
at ICAR-Directorate of Weed Research, Jabalpur, Madhya Pradesh. The experiment comprised 10 treatments having
combinations of sole and sequential application of pre-emergence and post-emergence herbicides in both the crops,
and their integration with hand weeding undertaken in randomized block design replicated thrice. The highest system
productivity (8.04 t/ha) was obtained by employing two hand weedings, sequential application of pendimethalin followed
by (fb) imazethapyr in soybean and pendimethalin fb mesosulfuron + iodosulfuron in wheat as well as by integrating
either pre or post-emergence herbicides with one hand weeding. Among weed management practices, energy requirement
was lowest in sole post-emergence herbicide treatment, however, integration of manual weeding required maximum
energy. The energy input for hand weeding was a major share of integrated weed management practices, and it varied
from 54–83% of the total treatment energy. Due to requirement of less energy for sole post-emergence herbicides,
energy output, net energy return and energy ratio were the maximum. Total output energy was higher (258×103 MJ/
ha) in post-emergence herbicide fb hand weeding treatment because of higher system productivity (7.29 t/ha), and this
treatment was more energy efficient and gave the highest economic returns among the weed management practices.
The highest benefit: cost ratio (3.10) was obtained by the application of post-emergence herbicides in both the crops.
