tailieunhanh - Changes in soil dehydrogenase activity and herbicide efficiency index as influenced by different tillage and weed management practices under rice - maize cropping system

A field research was carried out during 2015-16 and 2016-17 at Instructional cum Research Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur. Fifteen treatment combinations (Five tillage and three weed management practices) were tested in split plot design with three replications. Soil dehydrogenase activity was not influenced significantly by different tillage practices alone and in combination of tillage and weed management practices. However, dehydrogenase activity was significantly influenced by weed management practices under rice maize cropping system both the years of study. Dehydrogenage activity was found higher due to application of oxadiargyl 90 g ha-1 PE fb pinoxsulam g ha-1 PoE over other herbicide combinations in rice. Maximum dehydrogenase activity was recorded under unweeded control. | Changes in soil dehydrogenase activity and herbicide efficiency index as influenced by different tillage and weed management practices under rice - maize cropping system
