ABSTRACT
A field experiment was carried out at Horticultural Research Station, Chintapalli, from 2009-2012 to find out effect of different organic sources of nitrogen in comparison with recommended dose of fertilizers (RDF) on growth, yield and economics of turmeric (Curcuma longa L.) cv. Roma. The experiment was laid out in RBD comprising of nine treatment combinations replicated thrice. The pure and combinations of different organic manures such as farm yard manure, vermicompost, neem cake and inorganic nutrients (100 % RDF and 50 % RDF) with one absolute control were tried. In the present study, it had been observed that application of FYM 15 t/ha + Vermicompost 3.8 t/ha + Neem cake 1.5 t/ha (T4) significantly enhanced the plant height, number of tillers, leaf area and stem girth followed by Vermicompost 7.5 t/ha + FYM 7.5 t/ha + Neem cake 1.5 t/ha (T5) and Neem cake 3 t/ha +FYM 7.5 t/ha + Vermicompost 3.8 t/ha (T6). Significantly higher fresh rhizome yield (606.54 g/plant), projected dry yield (7.6 t/ha), curing (25.25%), curcumin (5.3%) and essential oil (4.2%) were also observed in T4 followed by T5 and T6. Economic assessment of different treatments revealed that, maximum net return, the highest B: C ratio (3.69) obtained from T4 followed by T5 (3.02) and T6 (3.0) as compared to control (0.19).
