Nutrient management of dill (Anethum sowa l.) through organic and inorganic management
Abstract: An experiment was conducted at HRS, Mondouri, BCKV, Nadia, West Bengal during rabi season of 2011-12 and 2012-13. Three levels of inorganic fertilizers i.e. 25, 50 and 75 per cent of recommended NPK (80:40:40 kg h-1) and five biofertilizers namely Azospirillum lipoferum, Azotobacter chroococcum, phosphate solubilising bacteria (Bacillus polymixa), arbuscular mycorrhiza (Glomus fasciculatum) and potassic mobilizer (Fraturia aruntea) were included. PSB and AM were applied separately with Azotobacter and Azospirillum along with each level of inorganic and potasic mobilizer. The experiment was laid out in RBD with 3 replications. The sowing and harvesting were done during 1st week of November and last week of March respectively. Maximum plant height (164.34 cm), number of secondary branches plant-1 (18.72), stalk length (26.15 cm), diameter of umbel (16.27 cm), number of umbel plant-1 (124.67), number of flowers umbel-1 (1229.67), seed yield plot-1 (509.33 g per 5.4 m2) and projected yield (707.5 kg ha-1) were recorded in NPK (50%) + Azospirillum + PSB + KM as compared to recommended dose of inorganic fertilizer (152.16 cm, 11.44, 23.74 cm, 14.20 cm, 86.56, 956.83, 395.50 g and 549.30 kg respectively). Combination of Azospirillum + PSB + KM along with 50 per cent RDF was best for higher yield of dill and there is a chance of saving of 50rnper cent inorganic fertilizers.
