IMPORTANCE OF STUDY CROPS Dept. of Agronomy, TNAU, Coimbatore. DWSRC ParticularsArea of crops in m.ha. Production in m.tonnes Productivity in qtls Paddy Maize Sugarcane All Crops58.43
Dept. of Agronomy, TNAU, Coimbatore. DWSRC Paddy and Maize occupy nearly 36 per cent of the cropped area Sugarcane occupies around 7 percent Weeds alone causes around 30 per cent reduction in yield levels Hence efficient management of weeds become primary objective for the farmers Farmers follow traditional methods and modern methods Modern methods include integrated weed management Hence the present study
Integrated Weed Management Cultural Manual Mechanical Chemical Dept. of Agronomy, TNAU, Coimbatore. DWSRC
OBJECTIVES To observe the benefits of Herbicide application To assess any conservation of resource use To analyze the difference in productivity levels of the crop between the herbicide applied farms and non- herbicide farms Dept. of Agronomy, TNAU, Coimbatore. DWSRC
