Abstract
The Present study was carried out to evaluate the effect of different tillage methods and weed management practices on yield and yield attributes of rice in rice-maize-greenmanure system of conservation agriculture.The present study is from the 5th year of experiment.A field experiment was conducted during kharif-2018, at AICRP on Weed Management, College of Agriculture, Professor JayashankarTelanagana State Agricultural University, Hyderabad.The experiment was laid out in split plot design with five main plots, three sub-plots and three replications.The main plots included five tillage practices such as i) conventional tillage transplanted rice fb conventional tillage maize, ii) Conventional tillage transplanted rice fb zero tillage maize, iii) conventional tillage direct seeded rice fb conventional tillage maize, iv) zero tillage direct seeded rice fb zero tillage maize with residue cover and v) zero tillage direct seeded rice with residue cover fb zero tillage maize with residue cover and sub plots including three weed management practices i.e., chemical weed management with recommended herbicides, Integrated Weed Management (IWM) and unweeded control.Transplanted rice recorded higher number of panicles, panicle length, panicle weight, test weight and lowest sterility percentage over direct seeded rice.Integrated weed management (IWM) recorded significantly superior number of panicles and panicle length whereas in terms of panicle weight and test weight, IWM and chemical weed management were comparable to each other.Significantly higher grain and straw yield was observed with transplanted rice.Within the direct seeded rice, conventional tillage direct seeded rice recorded superior grain and straw yield.Among the weed management practices IWM recorded significantly higher grain and straw yield.
