Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, India to study the effect of Jeevamrit (biozyme) on growth and herbage yield of brahmi (Bacopa monnieri). The experiment was laid out in Randomised Block Design (RBD) with 10 treatments replicated thrice. The experimental soil was sandy clay loam in texture, neutral in reaction, medium in organic carbon (0.69%), low in available nitrogen ( 206.44 kg ha-1) and medium in phosphorus (18.16 kg ha-1) and potassium (202.41 kg ha-1). A comparative study between natural, organic and inorganic farming was done through the treatments ie T1: RDF (100:60:40) kg/ha, T2: 500 litres/ha biozyme + 2.5 t/ha FYM, T3: 1000 litres/ha biozyme + 2.5 t/ha FYM, T4: 2000 litres/ha biozyme + 2.5 t/ha FYM, T5: 3000 litres/ha biozyme + 2.5 t/ha FYM, T6: 4000 litres/ha biozyme + 2.5 t/ha FYM, T7: 5000 litres/ha biozyme + 2.5 t/ha FYM, T8: 10 t/ha FYM, T9: 20 t/ha FYM, T10: 4000 litres/ha biozyme. The results revealed that the application of biozyme had significant effect on the yield and yield attributes like shoot length, No. of branches, No. of leaves, fresh and dry weight. It was found that the treatment T7 i.e., biozyme @ 5000 litres/ha + FYM @ 2.5 t/ha showed the highest fresh and dry biomass yield of 324.97 and 44.9 q/ha respectively which was significantly higher than the rest of the treatments. It can be attributed to the fact that there was an enhanced uptake of N, P and K in the treatment T7 i.e., 64.65, 15.26 and 66.00 kg/ha respectively. The total soil microbial population was found to be highest in treatment T9 i.e., FYM @ 20 t/ha (8.18 cfu × 104) because microbes feed on carbon content of the organic manure. Although the treatment T1 i.e., RDF (100:60:40) kg/ha showed dry biomass yield significantly at par with treatment T5 i.e., 3000 litres/ha biozyme + 2.5 t/ha FYM however, soil analysis showed that the inorganic treatment (RDF) did not enhance the soil organic carbon (SOC) content. Initially the SOC was 0.69% which later lowered to 0.65% in RDF (due to lack of soil rejuvenation) and increased to 0.71% in T5.Biozyme offers higher BC ratio (3.73) and hence greater returns on investment because it is prepared from locally available natural sources. Cost of farmyard manure is higher hence a lower BC ratio (2.37). The incredible results of higher doses of biozyme are because it contains significant amount of macro and micronutrients, vitamins and essential amino acid. It also contains plant growth promoting substances like Indole acetic acid (IAA) and Gibberelic acid (GA). Biozyme being a product of natural farming can be taken as a stellar alternative since chemical fertilizers inadvertently affect the environment by contaminating it through eutrophication and causing health hazards. Emission of green house gases is because of recommended huge dose of compost that leads to global warming. Through this investigation it can be concluded that biozyme improves soil sustainability and biodiversity by increasing the population of soil microbes which mineralize the nutrients in soil and make them available to the plants. Biozyme 5000 litres/ha biozyme + 2.5 t/ha FYM, gave highest BC ratio (3.73) and hence, can be considered as a better substitute to the spendy chemical fertilizers and bulky organic manures.ennullThesis
