ALLELOPATHIC EFFECT OF Rumex maritimus RESIDUES ON YIELD PERFORMANCE OF RICE (Pages : 4 - 10)

Allelopathy plays an important role in weed control and crop productivity. We conducted an experiment at the Agronomy Field Laboratory, BAU, Mymensingh to evaluate the allelopathic effect of the residues of Rumex maritimus on the yield performance of boro rice. The experiment consisted of three cultivars i.e; BRRI dhan28, BRRI dhan29 and BRRI dhan60 and four R. maritimus residues treatment such as 0, 1.0, 2.0, 3.0 t ha-1. The experiment was laid out in a randomized complete block design (RCBD) with three replications. The highest reduction of grain yield was obtained in no residue treatment. The highest number of effective tillers hill-1, number of grains panicle-1, 1000-grain weight, grain and straw yields were observed in R. maritimus residues applied @ 3.0 t ha-1 treatment. The heighest grain yield (5.83 t ha-1) and straw yields (7.53 t ha-1) were produced for BRRI dhan28 when R. maritimus residues applied @ 3.0 t ha-1. Results of this study indicate that R. maritimus residues showed varied effect on the yield of Boro rice. Therefore, R. maritimus residues might be used in the rice field as an allelopathic agent to assess its weed suppresive potentiality.Download
