Comparative study of Chemical (Farmer’s Practice) and Organic (under Inhana Rational Farming Technology developed by visionary scientist, Dr. P. Das Biswas, Founder, Inhana Biosciences, Kolkata) aman paddy (rainfed) cultivation was conducted at farmers’ field under large scale production in Mathurapur village, Kowgachi-II Gram Panchayat, North 24 Parganas of West Bengal during crop year 2012 – 2013. Farmers from the village volunteered in the programme under encouragement from local gram panchyat towards hand on experience regarding effectivity of organic farming system in paddy. Compost was prepared locally using Novcom composting (Developed by Inhana Biosciences) method by the project farmers taking poultry litter as raw material. Well matured compost was prepared (as indicated by brownish colour and earthy smell) within 20 days. Analysis of compost quality as per standard guideline confirmed its high quality. Total nutrient content (NPK) was varied from 3.86 to 4.74 percent (on dry weight basis) with microbial population in the range of 1016 c.f.u per gram moist compost; which was significantly higher than reference value as obtained for poultry compost. CO2 evolution rate (mean 2.74 mgCO2 – C/g OM/day) and phytotoxicity bioassay test value (mean 0.82) tallied with ideal standard range, confirming the maturity and non- phytotoxicity of the compost. Aman (rain fed) Paddy (Oriza sativa) variety Khitish and Minikit -3654 were used for the study. These two varieties were taken considering their common usage by the farmers of the Block. Seeds of Khitish variety were sourced from Gram Panchayat as provided by Government of West Bengal, while Minikit-3654 was sourced as foundation seed developed by Monduri Farm, BCKV, State Agricultural University, West Bengal, India. Agronomic components in terms of numbers of tillers/hill, productive panicles/m2, filled grains/panicle and 1000 grains weight (g) of organically grown paddy was comparatively higher than conventionally grown paddy and its cumulative effect was considered in terms of total yield under two different management systems. In case of paddy variety Minikit- 3654 yield under organic practice (i.e., Inhana Rational Farming Technology) varied from 3375 kg/ha to 4125 kg/ha with average value of 3750 kg/ha while 3000 kg/ha to 3750 kg/ha with mean value of 3563 kg/ha under conventional chemical practice. In case of Khitish variety yield under organic (i.e. under Inhana Rational Farming) was almost at par to chemical farming practice and varied from 3750 kg/ha to 4500 kg/ha with a mean value of 4125 kg/ha. Nutrient Use Efficiency (NUE) in terms of partial factor productivity (PFP) was higher in case of Khitish variety in comparison to Minikit-3654 irrespective of the practice undertaken. However, in both cases, nutrient use efficiency (NUE) was higher under organic practice which may be due to better N mineralization from Novcom compost as well as better N uptake efficiency of the plants under IRF Plant Management Package. This is perhaps significant because the nutrient availability is considered as a limiting factor under organic soil management particularly under waterlogged condition and in the soil which has been applied with synthetic fertilizers for many years. In terms of soil quality development, organic package of practice has shown positive indication towards enhancement of soil quality component like soil pH, available NPK and specially soil microflora enhancement where as under conventional practice no such variations were noted. There is higher net income in case of Minikit variety but as the cost of cultivation under Inhana Rational Farming being is almost similar to chemical farming practice, there is potential for further higher net income if the produce is sold at even 10 percent premium price as organic item. The technology has most convincingly demonstrated its potential to ensure successful organic paddy cultivation in the most cost- effective manner and can definitely bring about economic prosperity among the farming community if adopted on a further larger scale. Significantly all these results were achieved in the very first year of application. The ecological and social cost of industrial agriculture, if considered; then this performance certainly promises clear potential towards sustainable organic cultivation for resource poor and marginal farmers.

Evaluation of Inhana Rational Farming (IRF) Technology as an EffectiveOrganic Option for Large Scale Paddy Cultivation in Farmer’s Field – A CaseStudy from Kowgachi-II Gram Panchayat, North 24 Parganas, West Bengal

A study was taken up during 2014-16 for evaluating the potential of an organic package of practice towards integrated crop production (green farming) in comparison to conventional farmers’ practice in West Bengal, India. Under green farming, compost was integrated with chemical fertilizer for soil management while organic plant/ pest management was undertaken utilizing Inhana Rational Farming (IRF) Technology. The study indicated higher yield (9.7 %), higher nutrient use efficiency and economic sustainability under green farming irrespective of study area or potato variety. Higher qualitative expression in terms of starch content, pulp pH, vitamin C etc. under green farming might be due to the organic plant management aimed at energization of plant biochemical functions. Soil quality development as noted under green farming might have been influenced by the on-farm produced compost containing rich self- generated micro flora (in order of 10 16 per colony forming unit.). The study indicated that green farming may serve as an efficient substitute of conventional farming towards yield sustenance, abatement of food toxicity and quality end product; through higher use of renewable energy and activation of plant physiological functions.

Dumping of c oir pith, the by product of coir - industry is po sing serious environmental problem s in the s outhern states of India, especially Kerala, Tamil Nadu, Andhra Pradesh and Karnataka , India . A study was conducted at Vaniampara Rubber Estate ( Kerala , India ) to demonstrate the potential of Novcom composting method towards production of quality compost using coir - pith as raw material . Novco m coir pith compost was pr oduced within a period of 21 days with one turning of the compost heap o n 10 th day. Physicochemical and fertility status of compost resemble d the standard set by different international composting council s , while its total nitroge n (1.48 percent) content was much higher than coir pith compost produced using other composting processes. The high value of nitrogen might be due to i ntense biodegradation process , which lower ed the potential for N loss and favorably influenced atmospheri c - N fixation through naturally generated autotrophic micro flora within compost heap. The finding was corroborated by the high population of microb es (10 14 to 10 16 c. f. u. per g moist compost) within compost, which were generated naturally during the com posting process. Maturity and phytotoxicity bioassay test s confirm ed that Novcom coir pith compost was mature and free from phytotoxic effect. The study conclude d that Novcom composting method c ould be an effective and economical process fo r speedy convers ion of coir pith in to a valuable input for organic soil management .

Restoration of soil has been identified as the option; to ensure crop sustainability. However, as per Trophobiosis Theory of French Scientist F. Chaboussou, focus on development of healthy plants is necessary to abate pest and disease invasion so as to ensure sustained crop performance, even under unfavorable environmental conditions. The present study, in randomized block design with green gram as test crop; was undertaken in Krishi Vigyan Kendra (Howrah, West Bengal) to evaluate the effectiveness of Inhana Rational Farming (IRF) Technology towards crop yield and soil quality development under different sustainable models viz. organic cultivation, integrated soil with organic crop management and non- chemical crop management; as compared to conventional farming practice. Highest yield was recorded under organic (933 kg ha-1) followed by integrated (921 kg ha-1) and non- chemical plant management (902 kg ha-1). The results were well corroborated with the plant development index obtained under these treatments. Favorable trend of soil quality under sustainable models especially in terms of microbial properties indicated the role of quality compost towards speedy rejuvenation of soil dynamics. The study indicated that reduction of synthetic fertilizers and qualitative management of soil is essential to restrict yield decline. However, plant management shall be prerequisite for ensuring crop sustainability without any time lag and under the changing climatic patterns. In this respect the potential of IRF Technology has been well accounted.

Evaluation of an Organic Package of Practice Towards Green Gram Cultivation and Assessment of its Effectiveness in Terms of Crop Sustainability and Soil Quality Development

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...

Self-generated microbial population or cultured microflora – an important criterion toward development of an effective and economically viable road map for organic soil management

The effectivity of Inhana Rational Farming (IRF) Technology was critically evaluated as a model of Sustainable Farming Practice in farmers’ field using okra (variety : Shakti - F1 hybrid) as test crop. The stusy was conducted at Binuria village in Birbhum District of West Bengal during February to October (2013). The village is in close vicinity of Visva Bharati University, Santiniketan. The study area lies in 23.660 N and 87.630E at about 179 ft. above MSL, with level to nearly level landscape. The experiment was laid down as per randomized block design (RBD) with 7 treatments replicated 3 times. The treatments included local farming practice with chemical inputs, organic farming practice (Inhana Rational Farming (IRF) Technology’ developed by Dr. P. Das Biswas, Founder, Inhana Biosciences, Kolkata) as well as integrated farming practice (combination of chemical and organic inputs for both soil and plant management). The most significant finding was that 100% reduction of chemical pesticide can be economically viable in the very first year with adoption of IRF Organic Package of Practice, under which 13.6% yield increase was recorded as compared to conventional farmer’s practice. Also when IRF was adopted for integrated cultivation model, higher yield as well as higher net income was obtained in comparison to conventional Farmer’s practice. Upto 144.5% higher Nitrogen Utilization efficiency and 32.8 % higher partial factor productivity was recorded under treatments with IRF Package. This higher response might be due to increased uptake and utilization of indigenous nutrients under the influence of high quality Novcom compost containing huge population (in order of 1016 c.f.u per gm moist compost) of self- generated microbes, which led to better nutrient (both macro and micro) mineralization in soil for plant uptake. This was also complimented by IRF Plant Management Package, which perhaps enhanced plant physiological functioning in terms of better N uptake and its utilization within plants.
