Pangasianodon hypophthalmus (sutchi catfish) is a fresh water catfish extensively being cultured in the South East Asian countries in the recent years. The present study provides the first report on the effects of gutting on the quality characteristics of aquacultured sutchi catfish stored in ice. pH of whole ungutted and gutted catfish didn’t show significant difference (p > 0.05) during ice storage period. Total Volatile Base Nitrogen (TVB-N), Alpha Amino Nitrogen (AAN), Free Fatty Acids (FFA) and Thio Barbituric Acid Reactive Substance (TBARS) were lower in gutted fish compared to whole ungutted fish at any particular day during ice storage. However, gutted fish expressed higher rate of primary lipid oxidation than ungutted fish. Textural degradation of the fish muscle as indicated by hardness, cohesiveness, springiness and chewiness was lower in gutted fish. Results of sensory evaluation revealed that gutting has significantly improved the sensory quality of the fish. However, microbiological analysis revealed higher Total Plate Count (TPC) and Enterobactereaceae count in gutted fish. The shelf life of gutted and whole ungutted sutchi cat fish as determined by microbiological analysis was 16–18 days and 18–20 days respectively while storage in ice. © 2014, Association of Food Scientists & Technologists (India).

A hand cranking mechanical frictional setup was developed using anthropometric dimensions of Madhya Pradesh farm women. The setup had a provision for attaching on-line torque transducer. Variable crank length was provided that could be adjusted as per the farm women (workers). The setup had also a provision for rising up and down to match workers' conditions. Isometric torque was measured at each quadrant positions of handle (0°, 90°, 180° and 270°) at different crank lengths (17.5, 21, 24, 27 and 30 cm). Higher torque was developed by farm women in standing posture as compared to sitting. The crank length up to 27 cm gave better torque at nearly all positions. The lowest torque may be considered for designing the equipment amongst all positions of handle so that human being could easily operate the equipment.

Rainfed agro-ecosystem occupies 68% of India's cultivated area and supports 40% of the human and 65% of the livestock population. Dairy animals play an important role in the sustainable livelihood of poor people of rainfed agroecosystem, because of inherent risk involved in the crop farming due to uncertainty of rainfall and occurrence of recurrent droughts. The objective of the study was to characterize the status of smallholder dairy production systems in rainfed areas to generate information that would assist in designing of strategies for dairy development programmes. These objectives were achieved by adopting a participatory system approach, which uses diagnostic survey and techniques of participatory rural appraisal. The dairy production systems in rainfed areas are complex and generally based on traditional and socio-economic considerations mainly guided by available feed resources. Scarcity of feed and fodder resources, low production potential of animals, non-availability of critical inputs/services in time, access to capital and markets were the primary reasons behind low productivity of dairy animals. The study suggested that the participation of farmers is essential for developing and promoting the technical interventions. To enable the rainfed farmers for dairy development, a favourable policy environment in terms of access to micro-credit, assured market and veterinary services have to be provided and socio-economic and technical constraints needs to be addressed.

Pollination biology of Annona squamosa was investigated in the context of functional specialization and pollination syndrome. Hermaphroditic flower exhibited protogynous dichogamy as stigma became receptive a day before anther dehiscence. Flowers produce moderately high number (16,280 ± 324) of spherical and medium size (98.6μm × 87.3μm) pollen with pollen/ovule ratio of 120.6. Nitidulid beetles; Carpophilos domidiatus and Carpophilos hemipterous were identified as pollinators in terms of visitation frequency, pollination potential index score and pollination efficiency. However C. hemipterous was relatively effective pollinator than C. domidiatus. Floral traits and specific reward system of A. squamosa clearly exhibit obligate specialization by filtering only C. hemipterous and C. domidiatus as pollinators and thereby explicitly indicating canthrophilous pollination syndrome. © 2012 Elsevier B.V.

Barley (Hordeum vulgare L.) is an important feed purpose cereal grown under diverse production conditions and harsh environments. The present investigation was carried out to study performance of advanced breeding lines and identify superior genotypes of feed barley using multienvironment trial data from All India Coordinated Wheat and Barley Improvement Programme (AICW&BIP). Ninety three experimental genotypes and five released cultivars were tested across eleven locations during four years. Grain yield and other agronomic traits were analyzed. Stability and genotype superiority for grain yield and other traits were determined using genotype and genotype × environment (GGE) biplot analysis. The result showed that environment and genotype contributed 32.9 to 67.4% and 4.7 to 20.4% of the total variation, respectively. The genotype × environment interaction contributed 27 to 44% of total variation. The experimental genotypes showed arrays of variation for grain yield in each year, with mean values ranging from 2.12 to 5.36 t/ha. Twelve experimental genotypes were identified, which were either superior or equal performance to the best check based on their high yield and stability across environments. The locations Varanasi, Kanpur, Vijapur and Durgapura discriminated the genotypes more than other sites for grain yield and agronomic traits. The findings provided valuable information on wide adaptation of feed barley genotypes, which could be useful for barley improvement programmes. © 2014, Indian Agricultural Research Institute, All rights reserved.

Spices and condiments are important cash crops in Odisha. About 2.17 lakh tonnes spices are being produced annually from 2.37 lakh ha area. However, storage losses of spices are very high (30 - 40%) due to inappropriate storage practices. Therefore, the present study was carried out during 2009- 2010 to assess the current status of the traditional practices followed by farmers in general and women in particular for storage of spices and condiments in Odisha for ginger (Zingiber officinale Rosc.), turmeric (Curcuma longa L.), chilli (Capsicum annuum L.), onion (Allium cepa L.), garlic (Allium sativum L.) and coriander (Coriandrum sativum L.). Four districts of Odisha namely Khurda, Ganjam, Kandhamal and Keonjhar were selected where these spices are cultivated and stored by the farmers. The sample consisted of 360 farmers including 180 women. Observations revealed that a large number of farmers still practice the traditional storage system. Ginger and turmeric are stored in pit method, heap method and in situ method while chilli, onion and garlic are stored in a mesh bags and hanging method. In traditional method of storage, farmers are depending on local resources and practices. Spices are stored by the farmers of Odisha mainly for home consumption, seed purpose and for income generation. Storage losses were recorded 10 - 15% in ginger, 20 - 30% in turmeric, 10 - 15% in onion and garlic in traditional method of storage which were less as compared to who has not adopted storage practices.

Fish meal and fish oil are the major ingredients used for production of feed for aquaculture. A study was conducted in three coastal states of India viz., Karnataka, Kerala and Tamil Nadu in order to assess the functioning of fish meal plants, covering raw material sourcing, production process, marketing and constraints in the operation. Oilsardine is the major fish used for fish meal and fish oil production in the 35 fish meal plants operating in various coastal states of India. The installed capacity of fish meal plants varied from 20 to 350 t of raw material per day. About 65,000 t of fish meal and 34,000 t of fish oil are annually produced in the three states of Karnataka, Kerala and Tamil Nadu. Fish meal is sold at Rs. 40-50 per kg and fish oil at Rs. 50-55 per kg.

Sixteen Indian commercial carrot cultivars were analysed for variations in β-carotene, total phenolics, total flavonoids, total monomeric anthocyanin and antioxidant activity. Antioxidant activity was measured using four in vitro assays viz. ferric reducing antioxidant power (FRAP), cupric reducing antioxidant power (CUPRAC), 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and Trolox equivalent antioxidant capacity assays (TEAC). Additionally six colour attributes were evaluated. Among carrot cultivars, significant differences (p<. 0.05) were obtained with respect to antioxidant composition and antioxidant activity. Total phenols and total flavonoids varied from 7.98 to 291.48. mg/100. g fresh weight (fw) and 3.00 to 111.70. mg/100. g fw respectively. Chemometric tools like principal component analysis (PCA) and agglomerative hierarchical clustering (AHC) were applied to understand possible classification Indian carrot cultivars based on colour properties, bioactive antioxidant compounds and antioxidant potentiality. PCA revealed that the first two components represented 92.9% of the total variability in the total variation. AHC classified cultivars into four main groups on the basis of the measured parameters. Black coloured genotype was found to be rich source of phenols, flavonoids and anthocyanin with very high antioxidant activity. Orange cultivars were found to be rich sources for β-carotene compared to red & black cultivars. © 2013 Elsevier Ltd.

The importance of Public Private Partnership (PPP) in agriculture is understood in terms of a shared mechanism among partners for input, resource, market, risk, technology and benefits. In addition, review of various studies indicated the visibility of PPP in various facets of knowledge management, capacity building of women and youth, development of high end technologies, processing and market promotion and gender mainstreaming in agriculture. The partnership approach apart from developing certain technologies also empowered farmers in terms of enhanced access to technology and market in India through organized farmers groups. Farm women from difficult areas were enabled to empower themselves through gender mainstreaming techniques. The limitations of PPP such as focus mainly on high end technologies, high profit margin areas and crops, perceived mistrust and lack of transparency and non-adherence to agreement among partners could be overcome through appropriate working mechanism and policy support. Establishing PPP cell at research and development organizations would spearhead the growth of PPP and thereby sustainable agriculture and livelihood of millions of poor farm families in India.
