Heat map representing the variation of chemical compounds identified in the essential oil of Salvia sclarea in response to mulch and nitrogen management. M1 and M2 represent without mulch and with mulch, respectively, while S1, S2, S3, S4, S5 represent nitrogen management Control, 100% N (CF), 25% N (CF) + 75% N (FYM), 50% N (CF) + 50% N (FYM) and 75% N (CF) + 25% N (FYM), respectively.
