Integrated nutrient management is an environment friendly approach of plant nutrition being used for crop productivity and improvement in soil quality on sustainable basis. A three-year multi-location experiment was conducted to estimate the spice quality of saffron subjected to the integration of organic and inorganic nitrogen sources. At each location, the experiment was laid out in randomized complete block design. The treatments were T1 = control (without organic/inorganic N source/amendment); T2 = Full recommended nitrogen (i.e. urea fertilizer @ equivalent to 100 kg N ha−1; UN100); T3 = Poultry manure (PM) @ equivalent to 100 kg total N ha−1 (i.e. PM100); T4 = Farm yard manure (FYM) @ equivalent to 100 kg total N ha−1 (i.e. FYM100); T5 = PM50+FYM50; T6 = UN75 + PM25; T7 = UN50 + PM50; T8 = UN25 + PM75; T9 = UN75 + FYM25; T10 = UN50 + FYM50; T11 = UN25 + FYM75 and T12 = UN50 + PM25+ FYM25. Among treatments, poultry manure (100%) and urea nitrogen with poultry manure (UN50 + PM50) significantly affected the quality attributes of saffron. On the other hand, among sites, the crocin, picrocrocin and saffranal contents were in order of Khaigala (23.81% crocin, 20.01% picrocrocin and 0.27% saffranal) >Trarkhel (19.04% crocin, 16.99% picrocrocin and 0.25% saffranal) and > Abbaspur (17.80% crocin, 15.45% picrocrocin and 0.23% saffranal). Similarly, among years, the crocin, picrocrocin and saffranal contents were significantly higher in the third year compared to the first and second year. In conclusion, the integration of organic nitrogen sources with inorganic nitrogen has the potential to improve saffron quality. [ABSTRACT FROM AUTHOR] |
