A field experiment was conducted at Jammu, during the spring season 2013 to evaluate the efficacy of tembotrione (42% SC) on nutrient removal by crop and weeds in spring maize. The experimental field was highly infested with Cyperus rotundus, Cynodon dactylon, Phyllanthus niruri and Digitria sanguinalis. Post emergence application of tembotrione @ 120 g/ha at 15 DAS resulted in significantly highest NPK uptake by grain and stover of crop and lowest NPK uptake by weeds which was at par with post emergence application of tembotrione @ 120 g/ha at 30 DAS and two hand weeding at 15 and 30 DAS. |
