Effect of Different Clipping Heights on the Green Fodder, Hay and Seed Production of Four Cultivars of Transplant Aman Rice

M. Ahmed, M.S.H. Molla and A.H.M. Razzaque    

Abstract: The objective of this study was to see if it is possible to grow rice as a duel purpose crop i.e. as a source of green fodder and seed/grain. Results obtained from the experiment involving a) four leaf clipping heights viz. 10, 15, 20 cm and control (no clipping) and (b) four cultivars of rice viz. Latishail, BR10, BR11 and BRRIdhan32 revealed that green fodder yield decreased with the increase in height of leaf clipping. The lowest and highest green fodder yield were obtained from 20 and 10 cm clipping height, respectively. The identically highest green fodder yields were found by cultivars Latishail and BR11, respectively and the lowest by BRRIdhan32. Plant height was positively related to leaf clipping height. The highest and lowest plant heights at harvest were found in control (no clipping) and 10 cm clipping treatments, respectively. Hay yield and seed yield decreased with the decrease in height of leaf clipping. The lowest and highest yields of both hay and seed were obtained from 10 cm clipping height and control (no clipping), respectively. Clipping at 20 cm was statistically identical with control (no clipping) in respect of hay and seed yield. The highest hay and seed yields were found by cultivar BR11. It is possible to harvest rice green fodder from transplant aman rice like BR11 and the height of leaf clipping may be up to 20 cm at vegetative growth stage.
