EFFECT OF WEEDING REGIME AND PLANTING DENSITY ON MORPHOLOGY AND YIELD ATTRIBUTES OF TRANSPLANT AMAN RICE CV. BRRIDHAN41

A field experiment was carried out to investigate the effects of weeding regime and planting density on morphology and yield attributes of transplant aman rice cv. BRRI dhan41.Four weeding regimes viz., three hand weeding, two hand weeding, herbicidal control and no weeding were considered asfactor A, while four different planting densities viz. two, three,four and five seedlings hill^-1 were considered as factor B in splitplot design in RCBD. Data were recorded on plant height, number of effective tillers hill-1, weight of 1000 grains, grain yield plot-1and straw yield plot-1 and some other vital yield attributing characters. Highest value was recorded from the treatment combination of three hand weeding regimes with two seedlings hill^-1 in most of the evaluated traits. The weakest treatment combination was the no weeding with five seedlings hill^-1. So,three hand weeding and two seedlings hill^-1 are recommended to be practiced for transplant aman rice cv. BRRIdhan41 at farmers’fields in Bangladesh.
