Aim: The aim of this study was to evaluate effectiveness of various microbial compost cultures for aerobic-composting of farm wastes. Place of Study: Three trials were conducted on farmer’s field and one at Krishi Vigyana Kendra (KVK) Ramanagara district. Methodology: During the composting process, days to compost, maturity in terms of changes in temperature, pH and composting dynamics were studied. Compost quality parameters such as macro and micro-nutrients and C:N ratio and stability  of the compost were recorded at different intervals.  Results: The results showed that the compost culture from  IIHR and UASB had taken 90 and 105 days respectively, for complete stabilization; further had relatively higher temperature and pH during the initial phase and reached ambient condition at maturity stage, C:N ratio has showed gradual reduction from 39.65 to 15.98 and 39.75 to 13.66% respectively in IIHR and UASB cultures, they also had high macro, secondary and micro nutrients(IIHR-1.55% N, 0.93% P, 0.95% K, 4.39% Ca, 0.69% Mg, 0.19%S, 930 ppm Fe, 10ppm Cu, 305ppm Mn, 82ppm Zn, 26 ppm B  UASB-1.59% N, 0.91% P, 0.97% K, 4.25%Ca, 0.88% Mg, 0.21%S, 948 ppm Fe, 9ppm Cu, 325ppm Mn, 93ppm Zn, 28ppm B) content and resulted in more compost production ( 3.3 and 2.8 t/year, respectively) with B:C ratio of 6.67 and 7.25 respectively when compared to NCOF (T3) and farmers practice (T4). Conclusion: Aerobic-composting of farm waste using microbial culture of UASB and IIHR proved to be an effective technology that aids to convert organic farm waste into valuable organic manure with an advantage of minimizing the environmental contamination associated with burning of residues.

The aim of the study was to compare 10 winter triticale varieties according to their traits useful for cultivation in organic farming. The study was carried out in the years 2014–2017 in the experimental organic farm of the Institute of Soil Science and Plant Cultivation–State Research Institute in Pulawy (Poland). The highest-yielding varieties under organic conditions were Pizarro and Subito. Borowik cultivar showed the highest competitive ability against weeds. The highest number of weeds was found in the Leontyno cultivar, which was connected to the lowest plant density, the lowest weight of the above-ground parts of the canopy and smaller value of tillering coefficient. The most affected by the fungal pathogens Drechslera tritici-repentis (Died.) Shoem. and Puccinia striiformis Schwein. were Fredro and Algoso. Cluster analyses indicated that the most useful cultivars for cultivation in the organic system were: Borowik, Subito, and Tomko, which all showed higher yielding potential, bigger competitiveness against weeds, and average resistance against fungal pathogens. Pizarro, Tulus, and Twingo, which showed high resistance to fungal pathogens with lower competitiveness to weeds, were classified to the second group of usefulness. The least useful for the organic system were: Algoso, Fredro, Grenado, and Leontyno.

Set Up

India generates 0.15 million metric tons (MT) of solid waste per day out of which more than 80% is organic fraction. Apart from this, 38% of the households use septic tanks where proper disposal of faecal sludge is also need of the hour. Anaerobic co-digestion (ACD) of two different substrates has positive potential towards solving this problem. In the present study, ACD of organic fraction of municipal solid waste (OFMSW) and septage solids (SS) was studied at three different levels, i.e., lab-scale, pilot-scale (1 m3), and full scale- capacity (325 m3). A loading rate of 1.5 kg VS/m3 was selected. The bio-methanation potential (BMP) assay showed a maximum biogas generation, i.e., 120±20.6 mL/gmVS with 68% maximum methane concentration at a 5:1 OFMSW and SS ratio. Cumulative biogas production after 30 days was 1.6 L/gmVS. The ultimate biogas production in the pilot-scale plant was 1000±100.5 L/day with 71% methane. The plant was also efficient in removing 87% of COD and 61% of VS. The full-scale anaerobic digester was set up at Mormugao Municpal Council, Goa India wherein the objective was to co-digest OFMSW and SS. This digester showed a similar removal pattern like earlier studies i.e., 94% and 45% COD and VS removal, respectively. The average methane content of the biogas was 68%. Full-scale operation of the anaerobic digester did not show any operational problems at the chosen co-digestion conditions.

The firm Konyoka Multi-Purpose Organic Agriculture Farm was incorporated in 2016 in lines of farmers producers organisation with twin objectives of creating livelihood opportunities through integrated organic farm practices and reviving the barren flood plains of Jia Bhareli river. The academic aim of this case study is to analyse strategic decision of the firm in reviewing its supply chain and provide alternatives with a horizon of 05 years to 10 years in creating possible linkages and sustaining interest of its members. This case study discusses consumer behavior, food sovereignty, relationship between poverty, distressed selling, long-term business relationships, e-Commerce and CFPR practices, traditional supply chain, efficient logistic practices, organic farm produce markets, Government policy on farm subsidy and institutional support in organic farming in India vis-a-vis North Eastern India. Opportunities for the firm Konyoka discussed includes commercialization of plant varieties, agro-tourism, organic produce certification stages, and technology enabled solutions in customisation in secondary distribution. This case opens the scope of institution support (government) in organic farming and seriousness of political leadership in boosting confidence in primary sector. The case ends with leading solutions to excite the readers to design and appraise management issues in market linkages and change management.<br>
