A field experiment was conducted during Rabi 2018-19 at Rajasthan Agricultural Research Institute (SKNAU, Jobner), Durgapura, Jaipur, India to study the effect of water soluble fertilizers on crop growth, yield attributing characters, yield and economics of mustard under semi-arid conditions. The experiment was conducted in Randomized Block Design with 10 treatments in three replications. Different concentrations of water-soluble fertilizers in different combinations alongwith the recommended dose of fertilizers (RDF) was applied through foliar nutrition to the crop. The results of the study revealed that application of RDF along with first spray1.0 % urea phosphate+ 2nd spray of 2.0 % urea phosphate with SOP and 3rd spray of 2.0% SOP recorded significantly higher growth, yield attributing characters, yield, net returns and benefit cost ratio over recommended dose of fertilizer. Highest seed yield (3567kg ha-1) was recorded with application of RDF along with foliar applications of 1.0 % UP+ 2nd spray of 2.0 % UPSOP and 3rd spray of 2.0% SOP which was 27.3% higher than yields obtained in RDF alone. Highest Net Monetary Return (Rs.127121/ha) and B:C Ratio (3.37) was also recorded with application of RDF along with first spray of 1.0 % UP+ 2nd spray of 2.0 % UPSOP and 3rd spray of 2.0% SOP.
