 Abstract


The experiment was conducted on growth and dry matter partitioning to evaluate the productivity in terms of yield and yield contributing characters in four groundnut varieties viz., Binachinabadam-1, Binachinabadam-2, Binachinabadam-3 and Dhaka-1 at Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh, during November, 2006 to May 2007. Binachinabadam-1 and Binachinabadam-2 produced significantly higher pod and seed yields plant-1 (over 11 g pods and 8.2 g seeds) whereas, the Dhaka-1 showed the lowest values of these parameters (9.36 g pods and 7.09 g seeds). Likewise, Binachinabadam 1 and Binachinabadam-2 showed identical but significantly higher seed yields (3.51 and 3.60 t ha-1 respectively) whereas the Dhaka-1 showed the lowest yield (3.06 t ha-1). In Binachinabadam-1 and Bainchinabadam -2 there was more partitioning of dry matter towards pods (31.76 and 28.74%, respectively) whereas, Dhaka-1 showed the least (9.36%) although Binachinabadam-2 showed significantly the highest total dry mass (40.05 g plant-1).

Keywords: Dry matter partitioning, Groundnut and Yield contributing characters.
