Abstract:
Biozyme is a biodegradable and non-toxic for the plant and soil health containing growth hormones, elements, minerals and vitamins and highly compatible with fertilizers and pesticides, it also increases the resistance of plants against various pests, diseases and climatic stress. Keeping in view of its importance a field trial was formulated and conducted at Research cum Industrial Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) during kharif 2018-19. The Indira Rajeshwari (IGKV- R1) rice genotype was collected from IGKV, Raipur and seven treatments were consisted i.e. T₁ No treatment, RDF only 120: 60: 40 (control), T₂ RDF+ biozyme granule@15 kg/ha at 15 DAT, T₃ RDF+ biozyme grain @ 15 kg/ha at 15DAT and tillering stage, T₄ RDF + Biozyme grain@ 15 kg/ha at 15 DAT+ Biozyme liquid @ 500 ml/ha and 500ml/ha at boot leaf stage, T₅ RDF+ Biozyme granule @ 15 kg /ha at 15DAT and tillering stage+ 500 ml/ha at boot leaf stage, T₆ RDF+ Biozyme granule at 15DAT + Amaze X Gr.@ 10 kg/ha at tillering stage and T₇ RDF+ Biozyme granule at 15DAT + Amaze X Gr.@ 10 kg/ha @ 500 ml /ha at tillering stage+ Biozyme liquid at boot leaf stage in Randomized Block Design (RBD) with three replications. The biozyme was applied in form granular, liquid alongwith recommended dose fertilizer and the liquid treatments were through garden spray bottle plastic nozzle hand pressure spray head whereas; the granular were done by broadcasting method. The physiological, biochemical and yield traits were recorded under the application of (T₄ -RDF+ biozyme grain @ 15 kg/ha at 15DAT and tillering stage) as compared to control (T₁ RDF only) might be due to biozyme regulated plant bio-physiological activities which in turn resulted in higher chlorophyll content in leaves that’s help in maintaining higher photosynthetic activity.
