The design of equipment for harvesting, separating, cleaning, handling and storing of any agricultural commodity is influenced by its physical and mechanical properties. The physical properties and mechanical behaviour of turmeric rhizome were determined at different moisture content (6, 8 and 10 % on wet basis) under laboratory conditions. It was observed that physical properties increased linearly with increase in moisture content of rhizome such as length (54.46±8.45 to 55.79±8.61 mm), breadth (12.48±1.61 to 13.21±1.13 mm), thickness (11.32±1.41 to 11.65±1.00 mm), bulk density (555±0.84 to 563±2.54 kg/m3), true density (1337±2.91 to 1359±2.00 kg/m3), porosity (58.47±0.04 to 58.57±0.02 %), the angle of repose (35.87±0.02 to 37.42±0.04º). Mechanical properties coefficient of friction increased linearly (0.240±0.001 to 0.271±0.002) and rupture force decreased from 183.22±5.04 to 83.18±9.87 kg with an increase in moisture content of rhizome. The moisture content showed a significant effect on change in bulk density, true density, the angle of repose, the coefficient of friction and rupture force. However, properties like length, breadth, thickness and porosity are not significantly affected by moisture content.

Globally rainfed areas are hotspots of poverty, malnutrition and degradation of natural resources. Government of Karnataka (GoK) has converged all the Government schemes through a mission mode project called as “Bhoochetana” meaning “reviving the soils” to benefit dryland farmers for sustainable use of natural resources in Karnataka. The study aims to estimate the welfare impact of Bhoochetana programme in holistic manner. Multiple regression analysis was employed to evaluate the marginal effect of soil reviving programme among the adopters and non-adopters. The distributional effects of the programme on consumers and producers were assessed with the application of Economic Surplus (ES) model. Field information was composed from 120 farmers covering adopters and non-adopters of the programme. The application of micro nutrients was the major intervention of this programme and it had found to have significant impact on yield and income of selected crops. In groundnut the application of the micronutrients in adopter category resulted in increase in yield of 1.23 quintals extra over and above the non-adopters (5.9 quintals) and the total economic surplus due to adoption of programme was Rs. 2643 million from 2009-10 to 2015-16 with producers (72.56%) benefited relatively more than the consumers (27.43%). Whereas, in case of ragi, the adopters ragi yielded 2.02 quintals extra over and above the non-adopters (6.6 quintals) and distributional effect of consumers (54.93%) profit was relatively more than the producers (45.06%), with total economic surplus of Rs. 1933 million. Therefore, the policy focus must be on creating awareness and adoption of new technologies through developmental programmes in rural areas to reach millions of small farmers.

The experiment was conducted under new alluvial zone in West Bengal to evaluate the heritability for yield components and its impact on seed yield in 10 diverse genotypes of Lentil. In consideration of two successive years, the significant hierarchy was shown in 2nd year for the characters except in days to 1st flowering. ASHA and WBL-77 were effective for earliness in maturity among all genotypes. The maximum growth rate was observed in K-75 and KLS-218. The different varieties showed high significant variations in 1000 seed weight with top most effect in PRE-COZ. Interaction of two factors i.e variety (V) x year (Y) showed a significant variation in plant height and pod number, as well as seed yield through it, was non-significant in days to 1st flowering, maturity and seed weight. Results indicated that the genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) showed the genetic influence of these morphological traits. The heritability (h2%) in addition to high genetic advance as percentage of mean was >20% for most of the characters indicated the influence of additive gene. In observation of the correlation matrix, the total parameters maintained two distinct groups considering plant growth parameters and direct yield attributing traits. A negative or non-significant relationship was followed in between these groups of growth and yield traits though the strong positive correlation was followed within diverse traits of each group.

Custody images are a standard feature of everyday Policing and are commonly used during investigative work to establish whether the perpetrator and the suspect are the same. The process of identification relies heavily on the quality of a custody image because a low-quality image may mask identifying features. With an increased demand for high quality facial images and the requirement to integrate biometrics and machine vision technology to the field of face identification, this research presents an innovative image capture and biometric recording system called the Halo. 

Halo is a pioneering system which (1) uses machine vision cameras to capture high quality facial images from 8 planes of view (including CCTV simulated), (2) uses high quality video technology to record identification parades and, (3) records biometric data from the face by using a Convolutional Neural Networks (CNN) based algorithm, which is a supervised machine learning technique. Results based on our preliminary experiments have concluded a 100% facial recognition rate for layer 34 within the VGG-Face model. These results are significant for the sector of forensic science, especially digital image capture and facial identification as they highlight the importance of image quality and demonstrates the complementing nature a robust machine learning algorithm has on an everyday Policing process.

The nucleocapsid protein (N) gene of Groundnut bud necrosis virus (GBNV) associated with bud blight of tomato plants from different locations of Tamil Nadu viz., Coimbatore, Krishnagiri, Dharmapuri and Madurai was cloned and sequenced. The N gene comprised of 831 nucleotides and 277 aminoacids. The nucleotide sequence identities of the present isolates of the study ranged from 97.1% to 100%. Coimbatore isolate (MK032858) shared maximum sequence identity of 100% with Dharmapuri (MK032860) and Coimbatore isolates (AY618561) of tomato. Krishnagiri isolate (MK032859) shared maximum nucleotide sequence identity of 100% with Andhra Pradesh tomato isolate (AY510133). The aminoacid sequence identities of our isolate ranged from 97.8% to 100%. Krishnagiri isolate (MK032859) shared maximum aminoacid sequence identity of 100% with Andhra Pradesh isolate (AY510133). On this basis, it is concluded that the GBNV isolates from different crops and different agro-ecological zones have not much variation in nucleotide and aminoacid levels.

Introduction: The impact of climate change and responses are presently observed in both physical and socio-ecological system. Farmers’ vulnerability to climate-induced crisis refers to the inability of farm society to withstand adverse impact from multiple stress to which they are exposed due to climate change. However, climate-induced crisis introduced a new way of challenge not only because of an expected rise in temperature, CO2, the rise in sea level, etc. but failed to tackle adaptation strategies due to resource-poor, incompatibility, poor decision-making and incomplete information.

Objective: This paper examines the farmers’ action and adaptation strategies to manage the climate-induced crisis in coastal Karnataka.

Place and Duration of Study: The investigation was conducted in Coastal Karnataka during October 2014 to May 2015.

Study Design: 240 fishery-based farmers from 24 villages have been selected by applying proportionate random sampling technique for the investigation by adopting Ex-post-facto research design.

Results: The mean adaptation behaviour of crisis management groups with farmers’ categories was significantly varied as revealed by F ratios 188.72 and 25.46, respectively and they are observed to be significant at 0.01 level of probability. Also, the critical differences worked out for all the crisis management groups, and farmers categories turned out to be important noting that mean adaptability score group was dissimilar to other groups. There are various potential adaptation options available for climate change; often it varies from place to place, situation to situation, socioeconomic, psychological and other climate-related factors. However, there are limits to their effectiveness, efficiency, and equity. The result shows that their adaptation strategy to cope with the climate-induced crisis and it is important to integrate their local knowledge and wisdom with unnatural situations into the future planning and development process of the coastal belt.

Conclusion: Policies and development of adaptation strategies should not only be a necessity but, also be accepted and adopted by the local community for sustainable development.

Aim: In Côte d'Ivoire, several food products are made from cassava. However, this production generates effluents such as wastewater responsible for soil, as well as water and air pollution. Meanwhile, cassava wastewater can be used as an inexpensive substrate for the production of biopesticides, such as Trichoderma virens, a bio-control agent for black pod disease. This could address both the problems of cassava wastewater treatment and the use of conventional synthetic substrates for biopesticide production.

Methodology: The experiments described here were conducted using the cassava wastewater, without any supplement, to produce spores of T. virens by liquid state fermentation, solid state fermentation on kaolin grains. The production of gliovirin in cassava wastewater was monitored by LC / MS analysis.

Results: The maximum production (≈ 1.7 x 108 spores / mL) was achieved at dilution 1/4 of the cassava wastewater while at dilutions 1 and 1/2 the concentrations were 6.3 x 106 and 7.2 x 106 spores / mL, respectively. Spores concentration increased when cassava wastewater was highly diluted. The cultures of T. virens on kaolin supplemented with the cassava wastewater recorded a concentration of 1.13 x 106 spores / g of kaolin. The presence of gliovirin was detected by LC/MS analysis of solid state fermentation of T. virens in cassava wastewater.
