The effects of integrated nitrogen management (INM) on saffron yield, corm production, nutrient concentration, crocin content, and soil health were studied in field experiments at the Dryland (Karewa) Agriculture Research Station, Budgam District of Kashmir Himalayas, India, during 2006–2010. The levels of fertilizers applied were 0, 45, and 90 kg ha−1of nitrogen; 0, 30, and 60 t ha−1of farm yard manure (FYM), and 0 and 5 kg ha −1ofAzotobacterin solid form. The greatest yields of 3.64 and 3.51 kg ha−1were observed when nitrogen was applied at 90 kg ha−1and FYM was applied at 60 t ha−1. The increases over the controls (2.31 and 2.45 kg ha−1) were 57.57% and 43.26%, respectively. The maximum corm productions (10.26 and 13.10 t ha−1) were observed with the application of nitrogen at 90 kg ha−1and FYM at 60 t ha−1respectively, with the corresponding increases of 79.62% and 260.97% over their respective controls. Biofertilizer application in the form of viable strain ofAzotobactersignificantly increased the corm production only. The influence of INM on nutrient and crocin content of saffron and soil health was also found to be sustainable over nonapplication of organic and inorganic fertilizers. [ABSTRACT FROM PUBLISHER]
