Evaluation of non-chemical weed control methods in direct seeded rice (Oryza sativa L.) under rainfed condition of Nagaland

A field experiment, conducted at the experimental farm of School of Agricultural Science (SAS), Nagaland University, Medziphema campus, The was laid out in a randomized block design (RBD) with three replications and eight treatments. Among the treatments, application of stale seedbed technique followed by brown manuring was found the most efficient having lowest weed population and total dry weight and higher weed control efficiency. The same also produced higher plant height (117.30 cm), number of effective tillers plant –1, number of filled grains panicle–1 (99.47), grain yield (3.53 t ha–1), net return (Rs. 31038.83 ha–1) and B:C ratio (1.03) under direct-seeded rice.
