Abstract :

 

To observe the comparative performance of different organic manures with inorganic fertilizers on the 
growth rate, tillering and dry matter accumulation of rice an experiment was conducted in the Research Farm of  Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during June to November, 2008. The 10 treatments  comprised viz. T1 (Control), T2 (Green manure @ 15 t ha -1), T3 (Green manure @ 15 t ha -1  + N40P6K36S10 i.e.50% NPK), T4 (Poultry manure @ 4 t ha  -1 ), T5 (Poultry manure @ 4 t ha
-1  + N40P6K36S10 i.e. 50% NPK), T6 (Cowdung @  12 t ha -1 ), T7 (Cowdung @ 12 t ha -1  +  40P6K36S10 i.e. 50% NPK), T8 (Vermicompost @ 8 t ha -1 ), T9 (Vermiconpost  @ 8 t ha -1  + N40P6K36S10 i.e. 50% NPK) and T10 (N80P12K72S10 i.e.100% NPK). Plant height, number of tillers hill
-1 ,  total dry weight of plants, crop growth rate and relative  growth rate were significantly influenced by different  treatments. Except plant height and total tiller per hill all the parameters were found to be the highest with the  treatment T5 (Poultry manure @ 4 t ha -1  + N40P6K36S10 i.e. 50% NPK). The dry matter production showed a  significant relationship with grain yield of rice.  [Nature and Science 2010;8(4):1-10]. (ISSN: 1545-0740).
