Yield and Quality Parameters of Turmeric as Influenced by Application of Bio-Fertilizers and Organic Manures

摘要

An experiment was conducted to find out the effect of bio-fertilizers and organic manures on quality parameters of turmeric (Curcuma longa L.) during kliarif + rabi season of 2012-2013. Among the treatment combinations, T_7 0_3B, (VC 5 t/ha + Azospirillum 5 kg/ha) was recorded maximum 4.94% essential oil and it was significantly lowest 2.11% in treatment combination T_1 (O_0B_0No organic manure + No bio-fertilizer i.e. control). With regards to organic manures, the treatment 03 (Vermicompost 5 t/ha)was observed significantly maximum essential oil 4.51 % and it was minimum (2.87%) under the treatment O_1 (No organic manures) whereas, with regard to biofertilizers. Treatment B_1 (Azospirillum 5 kg/ha) exhibited maximum 3.98% essential oil in leaves,while the treatment B_0 (No bio-fertilizer) was recorded the minimum 3.25% essential oil in leaves.
