Evaluation of Inhana Rational Farming (IRF) Technology as a Cost Effective Organic Cultivation Method in Farmer’s Field

Inhana rational farming (IRF) technology was studied as an organic package of practice in farmers’ field using green gram (Samrat: PDM-84-139) as test crop. The study was conducted at Binuria village in Birbhum district of West Bengal during the crop season of 2013–14. The study area lies in 23.66°N and 87.63°E at about 179 ft above MSL, with level to nearly level landscape. The experiment was laid down as per randomized block design (RBD) with seven treatments replicated three times. The treatments included local farming practice with chemical inputs, organic package of 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). Compost application was an integral part of soil management under the studied organic package of practice (POP) and the same was produced on farm using Novcom composting method (developed by Dr. P. Das Biswas, Founder, Inhana Biosciences, Kolkata). Evaluation of the biodegradation process along with quality analysis of its end product (Novcom compost) indicated that Novcom composting method could serve as an effective alternative for conversion of agro waste into good quality end product. Highest greengram production was obtained under chemical and organic soil input integration @ 75:25 along with organic plant management (Yield: 715 kg/ha) followed by 100% organic (Yield: 699 kg/ha) and chemical farming practice (Yield: 665 kg/ha). At the same time, gross income under organic POP was higher than that that obtained under conventional farming practice. Comparison of value cost ratio (VCR) under integrated management vis-à-vis chemical practice confirmed better scope for economic sustainability when chemical pesticides/growth parameters were replaced by organic plant management inputs; as compared to application of chemical alone. Post harvest soil analysis showed that the plots receiving Novcom compost showed an overall positive trend in soil quality specially in terms of soil biological parameters. The findings indicated that IRF technology as an organic POP can serve as an economically viable option for large scale adoption in farmers’ field
