Clodinafop + metsulfuron, Sulfosulfuron + metsulfuron, Weed control efficiency, Weed density, Weed dry weight, Participatory rural appraisal

Farmers led on-farm trials were conducted in Morar and Bhitarwar blocks of district Gwalior during Rabi seasons of the year 2014-15 and 2015-16 in K.V.K. adopted villages to validate, refine and popularize the technologies recommended by Directorate of Weed Research, Jabalpur for managing grassy and broad-leaf weeds in wheat. Application of clodinafop + metsulfuron (60 + 2 g/ha) caused significant reduction in total weed counts (28.6 and 40.8/m2) and weed dry weight (3.5 and 4.2 g/m2) over farmer’s practice (2,4-D at 500 g/ha) as it reduced the population of both grassy and broad-leaved weeds and produced the highest weed control efficiency (83 and 82.6%) over application of sulfosulfuron + metsulfuron (30 + 2 g/ha) (70.87 and 76.03%) and farmers’ practice during both the year. Recommended practice of clodinafop + metsulfuron (60 + 2 g/ha) gave significantly higher grain yield (4.10 and 4.71         t/ha) over sulfosulfuron + metsulfuron (30 + 2 g/ha) and farmers practice. There were 21.42 and 22.46 and 12.18 and 9.87% increase in grain yield over farmers’ practice respectively under clodinafop + metsulfuron (60 + 2 g/ha) and sulfosulfuron + metsulfuron (30 + 2 g/ha) during the year 2014-15 and 2015-16. The highest net returns (` 51003 and 65267/ha) and B:C ratio (2.78 and 3.45) were recorded under recommended practice of clodinafop + metsulfuron (60 + 2 g/ha).
