摘要

Effect of three qualities of irrigation water having average electrical conductivity 2.85, 7.88 and 15.32 dS/m and four levels of nitrogen (0, 40, 80 and 120 kg/ha) were studied on growth, yield, oil and protein content of mustard on clay loam soilduring rabi 1998-99 and 1999-2000 at National Research Centre on Rapeseed and Mustard, Sewar, Bharatpur, Rajasthan. There was decrease in mustard yield with increase in salinity of irrigation water mainly due to decrease in siliquae/plant. Plant height,primary branches and seeds/siliqua also decreased with the increase in salinity. Nitrogen levels significantly increased the seed yield which was mainly contributed due to plant height, branching and siliquae/plant. Interaction of water salinity and nitrogen levels showed that higher doses of nitrogen were able to overcome the adverse effect of salinity upto salinity level of 7.88 dS/m. Saline water irrigation increased the salt build up in soil more so with salinity water at the time of crop harvest.
