Groundnut cultivation required frequent weed control practices for higher seed production, because groundnut is highly susceptible to weed infestation due to its slow growth rate at initial stage and its physiological characteristics like short plant height and underground pod bearing habit. To study the efficiency of two different aspects of weed control by organic and inorganic weed management on groundnut at Farmer's field of Karukupalayam village, Erode district, India.
A field investigation was conducted during Kharif season 2020–2021 at Krishna College of Agriculture and Technology, Affiliated to TNAU, Coimbatore-3, Tamil Nadu, India. The experiment was laid out in (RcBD) design with three replications. Ten different treatments are 1–5 were organic methods and 6–10 were inorganic methods.
The results of the experiments revealed that organic and inorganic treatments were tried, the least weed density, weed dry weight, weed index (18.24%) and highest weed control efficiencyand highest pod yield (2.33 t/ha) and haulm yield (3.05 t/ha), BC ratio (2.56) recorded in inorganic treatment of T9-PE pendimethalin @ 1.5 kg/ha at 2 DAS + PoE Imazethapyr @0.075 kg/ha at 14–20 DAS. It is significantly superior to all other treatments.
