The field study was carried out during kharif 2009-10 and 2010-11. The fertility status of the soil was moderate in organic carbon, low in available N and P and very high in available K while the soil micronutrient contents (Zn, Fe, Mn, Cu) were above the critical level. Experiment comprised of thirteen treatments replicated thrice in randomized block design, involving control (no fertilizer/manure), 5 t FYM ha-1, 10 t FYM ha-1, 80:20:40 kg NPK ha-1, 100:30:60 kg NPK ha-1, 140:40:80 kg NPK ha-1, 5 t FYM + 80:20:40 kg NPK ha-1, 5 t FYM + 100:30:60 kg NPK ha-1, 5 t FYM + 140:40:80 kg NPK ha-1, 10 t FYM + 80:20:40 kg NPK ha-1, 10 t FYM + 100:30:60 kg NPK ha-1, 10 t FYM + 140:40:80 kg NPK ha-1 and 100 kg N through FYM (based on FYM analysis). The results from the experimentation indicated that, the combined application of FYM + NPK @ 10 t + 140:40:80 kg ha-1 resulted in maximum plant height (140.20 cm) and number of tillers (58.43) followed by 5 t FYM + 140:40:80 kg NPK ha-1 which was significantly superior over rest of the treatments. Herbage yield was comparatively higher during the second year of the crop and it was increased successively with each combination of increasing FYM levels and graded doses of NPK. Significantly highest herbage yield was recorded with 10 t FYM along with 140:40:80 kg NPK ha-1. From the results, it can be concluded that the conjunctive use of FYM along with chemical fertilizer (10 t FYM + 140:40:80 kg NPK ha-1) was found beneficial way of nutrient management to increase the plant height, number of tillers and herbage yield of Java citronella.
