Abstract

ABSTRACT: A pot experiment was conducted to study the comparative effect of waste water (WW) and ground water (GW) alone and along with different nitrogen (N), phosphorus (P), and potassium (K) combinations (N0 P0 K0, N40 P15 K15, N60 P30 K30, N80 P45 K45 ) together with different levels of fly ash (FA) (FA0, FA10, FA20 ), to obtain a suitable combination of fertilizers, FA and water based on the growth, physiology, yield, and heavy metal contents of Brassica campestris cv. Pusa Gold. Results revealed that WW irrigation proved beneficial over GW. All the parameters increased in both levels of FA10 and FA20 along with three doses of NPK but FA at 20 t ha −1 proved better. The effect was more efficacious with both wastes together which makes NPK optimum at N60 P30 K30 instead of N80 P45 K45 treatment combinations and thereby lowered input of fertilizers. Therefore, utilization of these wastes may be recommended for the purpose of irrigation, soil amendment, and as a source of nutrients in augmenting the mustard yield.
