EFFECT OF SOIL SOLARIZATION ON PLANT GROWTH AND YIELD OF (Oryza sativa L.) RICE (Pages : 1 - 6)

A field experiment was conducted at Rangpur Dinajpur Rural Service (RDRS) Bangladesh, Sadar, Rangpur, during the period May 2007 to October 2007 to investigate the effect of soil solarization on plant growth and yield performance of BR11 and BRRI dhan33 seedlings. Solarized seedlings were raised in a seedbed covered with transparent polythene for two months before sowing. The experiment was laid out in a RCBD with five replications. The experiment was conducted under rainfed conditions. Solarization effect significantly influenced the crop characters, yield components and yield of rice. The seedling height (cm), root length (cm), shoot weight of seedling (g), root weight of seedling (g), number of galls (1 x 1 m seedbed), plant height (cm), number of tillers (hill-1), number of the effective tillers (hill-1), panicle length (cm), number of unfilled grain (panicle-1), filled grain (panicle-1), grain yield (t ha-1) straw yield (t ha-1) harvest index (%) were significantly greater in solarized treatment then non-solarized ones variation observed were in crop characters and yield contributing characters between two rice genotypes. Solarized seedlings produced the highest yield (4.9 t ha-1) while non-solarized seedlings produced the lowest yield (4.19 t ha-1). The interaction effect of solarization and varieties, Solarized seedlings produced the highest yield (4.92 t ha-1) in BR11 and lowest yield (3.80 t ha-1). This is an eco-friendly technique for raising healthy rice seedlings which has an excellent potential to use an IPM practice for rice cultivation. By practicing this technique, farmers can manage nematode and root disease to grow healthy plants resulting in rice yield increasing significantly.Download
