Abstract

Anaerobic treatment of bagasse wash water from paper and pulp mill was studied using a lab scale HUASB reactor of 7.88 L effective volume with three phase system. The initial characteristics of bagasse wash water were: pH 5.2-6.5, TCOD 2000-6000 mg/L, BOD 900-2500 mg/L, TS 4000-4500 mg/L, VSS 1000-1500 mg/L. The reactor was loaded with pulp and paper mill wastewater, seed sludge and activated Effective Microorganisms (EM) operated on continuous mode for a period of 130 days with an HRT varying from 24 to 8 hrs and start up with successful granulation has been achieved. An optimum TCOD removal was attained at the OLR of 7.8 kg COD/m³/day with TCOD removal of 81% with a gas production of 2.66 L/L per day and 70% of methane gas content with a production rate of 0.29 m³/kg COD removal were observed. The introduction of effective microorganisms has aided the start up period in an efficient way for better acclimatization inside the reactor that facilitate the biomethanation. The SEM analysis also shows stabilized Methanothrix and other microorganisms present in the reactor at the end of the start up.

Abstract

This investigation was carried out in Tamil Nadu Agricultural University, Coimbatore to test the bio efficacy of different seed dressing chemical on the management of sorghum shoot fly. The micro plot field experiments conducted in farm holdings at Chinnamatham palayam and Idikarai, Coimbatore District revealed the effectiveness of imidacloprid in checking shoot fly incidence by recording a mean minimum dead heart damage of 20 and 11 per cent in trial I and II, respectively. The experiments also showed maximum plant height of 39.2 and 39.7 cm in imidacloprid treated plots. In the laboratory, the assessment of seed dressing chemicals on the germination indicated maximum germination (92 %) of sweet sorghum seeds in imidacloprid treatment with maximum seedling vigour index (2401.2). Laboratory experiments showed no adverse effect of imidacloprid and thiamethoxam on seed germination.

Abstract

The North Eastern (NE) India is renowned for its preference for animal-based food. This region is known for its traditional meat products. However, the popularity of these products remains confined to the specific community/location. The knowledge on the traditional preparation methods is generally passed across generations through practice and word of mouth. The traditional style of preparation and the specific ingredients added to each product makes them unique. In this review, an attempt has been made to identify the initiatives, opportunities, and market potential for commercialization of the traditional meat products. These unique features and properties of the traditional meat products have been highlighted. The commercialization of these products will enhance entrepreneurship development and ensure quality ethnic products to the consumer in the NE hill region of India.
