Abstract
The experiment was carried out at the farmyard of the Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh, during the period from August 2017 to January 2018 to investigate the ameliorative effect of gypsum application on plant characteristics and yield, under various levels of salinity stress, of transplant Aman rice cv. Binadhan-10. The experiment was designed with three salinity levels such as control (M0), 5 dSm-1 (M1) and 10 dSm-1 (M2) NaCl, two gypsum levels such as control (G0) and 150 kg ha-1 (G1). To ameliorate the salinity stress t, gypsum was applied. Results revealed that the different levels of salinity had a significant adverse effect on plant height, the total number of tillers hill-1, number of effective tillers hill-1, panicle length, number of sterile spikelets panicle-1, 1000-grain weight, number of grains panicle-1, grain yield, straw yield, biological yield and harvest index. All the plants were affected badly when they were exposed to 10 dSm-1 salinity level. At salinity level of 5 dSm-1 grain yield reduction was 37%, which could be minimized to 14% by the application of gypsum. In case of straw yield, A similar amelioration effect was also observed. At 5 dSm-1 the grain yield was more improved from 3.46 t ha-1 to 3.93 t ha-1 when gypsum was applied. The grain yield reduction could further be improved at salinity level of 10 dSm-1 from 65% to 36% with the application of gypsum. At 10 dSm-1 the grain yield was more improved from 1.95 t ha-1 to 2.55 t ha-1 when gypsum was applied. The results of the study conclude that salinity stress could be ameliorated through the application of gypsum @ 150 kg ha-1 in transplant Aman rice cv. Binadhan-10.
