Effect of post emergence herbicides and their mixture on growth, yield and quality of soybean (Glycine max L.)

Abstract

A field experiment was conducted on medium black calcareous clayey soil at Junagadh (Gujarat) during Kharif 2018-19 and 2019-20 to study the effect of post emergence herbicides and their mixture on growth, yield and quality of Soybean (Glycine Max L.). The experiment comprising 12 treatments of various combinations of herbicides were replicated thrice in a randomized block design. The experimental results revealed that next to the weed free, IC & HW at 15 and 30 DAS, pendimethalin 900 g/ha as pre-emergence fb IC & HW at 30 DAS, pendimethalin 900 g/ha as pre-emergence fb pre-mix propaquizafop + imazethapyr 50 + 75 g/ha at 30 DAS and pendimethalin 900 g/ha as pre-emergence fb pre-mix sodium acifluorfen + clodinafop-propargyl 80 + 165 g/ha at 30 DAS enhanced growth parameters viz., plant height, branches/plant, number and dry weight of root nodules/plant, dry matter/plant yield attributes like, number of pods/plant and ultimately gave higher seed and stover yields along with improved quality parameters viz., protein content for cultivation of soybean under South Saurashtra Agro-climatic Zone of Gujarat.
