    INFLUENCE OF PLANTING MATERIALS AND PLANTING METHODS ON YIELD AND YIELD ATTRIBUTES OF INBRED AND HYBRID RICE
    (Sher-e-Bangla Agricultural University Research System, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh, 2007-07) Main, M.A.; Biswas, P.K.; Ali, M. H.
    A field experiment was carried out at Agronomy Field of Sher-e-Bangla Agricultural University, Dhaka, 2005 to study the influence of planting materials and methods on yield and yield attributes of aman rice varieties. The experiment consisted of three planting materials: Sprouted seed (M,), Nursery seedling (M,) and Clonal tiller (MJ); two varieties: Inbreed variety (BR II, Mukta) and Hybrid variety (Sonar Bangia-I); and two planting methods: Broadcast (T,) and Line (T,) sowing. The experiment was laid out in a split- split-plot design with four replications. Experimental results showed that planting materials had significant effect on the studied parameters like total and filled grains panicle", 1000-grain weight, grain yield and harvest index except effective tillers hill and straw yield. The highest grain yield (4.96 t ha") was obtained from clonal tillers and the lowest grain yield (4.24 t ha") from the sprouted seeds. Variety significantly influenced panicle length, 1000-grain weight and grain yield. The highest grain yield (4.70 t ha") was obtained from hybrid variety Sonar Bangia-I and the inbred variety BRII gave the lowest grain yield (4.43 t ha' I). Methods of planting influenced only on grain yield and harvest index. Line arrangement showed better performance with highest grain yield (4.81 t ha') than haphazard method (4.32 t ha' '). The combined effect of planting materials, varieties and planting method resulted in the highest grain yield from clonal tillers of hybrid variety with line sowing method.
