Abstract

The effectivity of Inhana Rational Farming (IRF) Technology towards energization of plant physiological functioning was evaluated in comparison to other organic packages of Practice under FAO-CFC-TBI Project at Maud Tea Estate, Dibrugarh, Assam, India during 2008 to 2013. The study area lies in 27.26. N latitude and 95.12 E longitude covering a total area of 154.58 ha area with level to nearly level landscape. The experiment was laid down as per randomized block design (RBD) with 8 treatments replicated 3 times. The treatments included available two organic methods viz. Biodynamic Farming (BD) and Inhana Rational Farming (IRF) (developed by Dr. P. Das Biswas, Founder, Inhana Biosciences, Kolkata) as well as organic inputs viz. vermicompost, bio-fertilizers, bio-pesticides, herbal formulations which are used in organic tea gardens in India on large scale. The organic inputs selected for evaluation were combined to form different ‘Packages of Practice’ based on scientific rationale. The different packages were : Biodynamic (BD) with Biodynamic compost, Conventional Organic Practice with Indigenous compost @ 13.5 ton/ha (CO), Inhana Rational Farming Tech-nology with 8 ton Novcom Compost (IRF-2), Inhana Rational Farming Technology with 5.1 ton Novcom Compost (IRF-4), Vermi-compost @ 9.4 ton/ha + Conventional Organic Practice (VCO), Vermicompost @ 9.4 ton/ha + Microbial Formulations for both soil and plant management (VMI), Vermicompost @ 9.4 ton/ha + Microbial Formulations for only plant management i.e. Bio-pesticides+ Bio-growth promoter (VMIP). Agronomic Efficiency (NUE), which among other factors depends upon the nutrient uptake and utilization efficiency of plant or con-versely the state of plant physiology was assessed to score the different organic packages as per N expensed for unit crop production. Highest NUE was obtained under IRF packages followed by VMI, VMIP and VCO. The highest crop yield along with high NUE under IRF-2 indicated an effective management ap

Abstract

Huge depletion of soil microflora under conventional farming practice has become the primary contributory factor toward the present depletion of soil and crop productivity. Reconstitution of soil microbial dynamics has been identified as the only way out, but there has been a debate regarding the most effective pathway for soil rejuvenation i.e. whether to create the environment for natural proliferation or opt for inoculation of laboratory generated microbes. In this respect, a study was undertaken at Maud T.E. (Assam) under FAO-CFC-TBI Project, where bio-fertilizer (microbial inoculant, MI), vermicompost (organic food source, OF), vermicompost + bio-fertilizer (OF+MI), and Novcom compost (representing self-generated native microflora in the order of 1016c.f.u. along with organic food source, SNM); were taken as treatments for a yield target of 1500 kg made tea/ha. The highest crop yield (1500 kg ha−1) along with high and consistent soil quality development was noted under SNM treatment; while MI influenced lowest yield (1268 kg ha−1) and minimal soil response. Addition of the organic food source with cultured microbes (MI+OF) was found to improve crop performance (1427 kg ha−1), but with 7.60 times higher cost (Rs. 39.97 kg−1made tea). Economic viability study indicated that except SNM, all other treatments were vulnerable toward crop loss or market downfall. [ABSTRACT FROM PUBLISHER]
