dc.description.abstractThe use of saline water for agriculture crop production is of paramount importance for the regions where groundwater is saline, water table is rising and the availability of good quality water is scarce. Three types of experiments i.e. micro plot study; field plot study and field column study were conducted. The experiment in the micro plots was conducted to study the varietal different in the salt tolerance of some of the BT cotton varieties. Field soil column experiment was conducted to calibrate the soil parameters of the selected model. The experiment in the field plots was conducted to observe crop yield which were used to calibrate and validate the model. Different cotton genotypes responded differently when irrigated with saline water. Cotton genotype Krishi Dhan 9810-BG-II gave considerably higher seed cotton yield than all the other genotyped when irrigation water salinity levels was > 2.5 dS m-1. The simulation model SWAP was calibrated and validated satisfactorily for predicting the effect of use of saline water for cotton crop. Model simulations showed that initial salinity of the root zone is an important factor and increasing the depth of irrigation is more beneficial than increasing the frequency of water application.en_US
