Effect of integrated weed management on growth and yield of kharif groundnut (Arachis hypogaea)

Abstract

The field investigation entitled “Integrated weed management in kharif groundnut” conducted during kharif 2017 at Experimental Agronomy farm section, Oil Seeds Research Station, Latur. The soil of experimental site was clayey, alkaline in reaction, low in organic carbon and available nitrogen and medium in available phosphorus and potash. The soil was well drained with moderate moisture retention capacity which was favourable for optimum growth. The environmental conditions were moderately congenial for growth and development of groundnut crop. Crop experiment was laid out in Randomized Block Design with three replications and 9th different weed control treatment viz. Chemical combination and cultural practice along with control plot. Among the chemical weed control methods, application of Pendimethalin 30% EC @ 1 kg a.i ha-1+ Imazethapyr 10% SL 0.075 kg a.i ha-1 at 20 DAS (PoE) (T6) had controlled the weeds more effectively in groundnut crop which helps in improving growth, yield, quality attributes, weed control efficiency, weed index with higher net return.
