Abstract

 

The effect of thermal power plant discharged waste water (TPPW) on growth, yield and quality of mustard (Brassica juncea L. cv. Alankar) and linseed (Linum usitatissimum L. cv. Neelam) was studied. TPPW increased growth characteristics, net photosynthetic rate, seed yield, oil content and oil yield of the two crops. In mustard, treatments TPPW N112P60 (112 kg N/ha + 60 kg P/ha), TPPW N112P30 (112 kg N/ha + 30 kg P/ha) and TPPW N90P60 (90 kg N/ha + 60 kg P/ha) were equally effective while in case of linseed lower levels of N and P with waste water proved beneficial. TPPW may be considered as an alternative of fresh water for irrigation purpose improving yield and quality of mustard and linseed.
