چکیده
|
The effect of different levels of zn (0,5,10 and 15 kg/ha) was evaluated on growth and ionic concentration of rice variety (cv. cm.204) directly sown on raised bed under saline-sodic soil. tillering,number of grains/spike,1000 grain weight and paddy yield significantly (p = 0.05) increased with the increase in the rate of zn application. paddy yield was the maximum at the application of 15 kg zn/ha,being 29% more than the control treatment. the maximum number of tillers/bill (62),number of grains/spike (121) and 1000 grain weight (26.40 g) were recorded with zn application @ 15 kg/ha. the maximum paddy yield (7906 kg/ha) was attained @ 15 kg zn/ha. the maximum zn (45 ppm) in grain was determined from treatment receiving 15 kg zn/ha followed by 10 kg zn/ha (38 ppm).
