Subject: Advanced coating on Zea mays seeds using modified hydroxyapatite nanoparticles as a plant nutrient delivery system for enhanced plant growth
Keywords: Agriculture, enhanced growth and yield, hydroxyapatite nanoparticles, maize, seed coating
Abstract: The deficiency of nutrients during the early plant growth stages diminishes plant development, leading ultimately to lower crop yields. In this context, nanotechnology has been used to develop advanced seed coatings with sustainable and precise release properties to deliver supplements to the plant effectively. Zinc-doped hydroxyapatite–urea nanoparticles were synthesized and incorporated into a seed coating. This system enhanced plant growth, yield and root–shoot nutrient content in Zea mays seeds. The nanohybrid is futuristic as a macro– micro plant nutrient delivery agent and opens up new opportunities to explore the suitability of metal-doped hydroxyapatite nanoparticles in agriculture

Subject: Assessment framework for public satisfaction on the urban water management attributes in Central India
Keywords: Assessment framework, city-planners, community participation, public satisfaction, urban water management
Abstract: Urban areas of the present and future can be sustainably transformed by involving community participation in decision-making because of their local knowledge. Most of the Indian cities have water management problems like accessibility, availability, quality, adequate infrastructure and user charges. Urban water management is one of the prime responsibilities of urban local bodies in India, but there is no provision to assess public satisfaction. This study focuses on the assessment of the satisfaction level of the public on urban water management in Central India to improve the efficiency of urban water. The methodology and proposed framework will help in distinguishing the poor functioning among water attributes that need to be strengthened to maximize the efficiency of the water management system.

Subject: Performance assessment of a bathymetry system in open inland waterbodies
Keywords: Acoustic transducer, bathymetry, echo sounder, waterbodies, water-depth measurement.
Abstract: Bathymetry of an open waterbody can be estimated remotely using airborne and space-borne sensors with wide coverage. However, unmanned aerial vehicle (UAV)- borne bathymetric systems are current trends for applications with limited depth subjected to the quality of water. Estimation of accurate bathymetry using surface based sensors is essential for validating the remote sening-derived results. To cater to the requirements of the in situ measurement system, especially for supporting the airborne (aircraft/UAVs) remote sensing-based bathymetry systems, a customized and compact, immersion-type bathymetry system using single-frequency (typ. 500 kHz) transducer was developed in-house at the National Remote Sensing Centre (NRSC), ISRO, Hyderabad. In the present study, we assess the performance of the developed system in the field against physical measurements and a reference acoustic transducer for shallow and deep inland open waterbodies. Performance testing was carried out in the Asan Lake, a shallow waterbody, with a depth of up to 4 m and in the Tehri reservoir for deep bathymetry with a depth of more than 150 m. The results show that the estimated TVU for the developed system during shallow bathymetry assessment was 0.272 m which complies with the IHO order 1. The observed performance of the developed system was consistent with the system specifications, which advocate its utility for hydrology and water resource management applications along with its intended use to support remote sensing based bathymetric systems.

Subject: Quantification of shoreline changes along the entire Indian coast using Indian Remote Sensing satellite images of 2004–06 and 2014–16
Keywords: Coastal erosion and accretion, high tide line, remote sensing, shoreline changes
Abstract: The coastal region of India is highly vulnerable to various threats, including coastal erosion, due to natural processes enhanced by anthropogenic influences. Shoreline change inventories are the pre-requisite for identifying the coastal stretches subjected to erosion. In this study, the shoreline of the entire Indian coast was delineated at a scale of 1 : 25,000 using IRS LISS-IV images of 2004– 06 and 2014–16 time frames. The spatial shift between the shoreline of two time frames was estimated in the GIS platform and a database of shoreline changes was prepared. The eroding, accreting and stable length of the shoreline were calculated for the Indian coast along with the area of erosion and accretion. This study discusses the imperative results of shoreline mapping and the status of shoreline changes on the Indian coast. The shoreline changes in terms of erosion and accretion were assessed for 7549 km of the Indian coast. It was found that the coast is eroding along 1144 km and accretion of the coast is along 1084 km, while 5321 km of the coastline shows no changes between the two time frames. The coastal land area lost due to erosion was 3680 ha; however, the increase in land area as a result of coastal deposition was 4042 ha. The regional coastal processes and the associated shoreline changes and coastal issues related to anthropogenic impacts are also discussed in this study. The inventory of shoreline changes has been used to prepare six volumes of Shoreline Change Atlas covering the entire Indian coast. The shoreline change database forms the baseline data for planning any coastal development activity by the maritime authorities apart from the potential use by the scientific community.

Subject: Addressing the impact of COVID-19 on dairy value chains: evidence from Punjab, India
Keywords: COVID-19 pandemic, dairy sector, digital platforms, disruptions, value chain management
Abstract: The COVID-19 pandemic has adversely affected dairy farmers with the demand shrinking due to income losses of the consumers, disruptions in the supply chains reducing supply, raising costs and increasing wastage. The present study examined such disruptions in Punjab, India, with the primary survey covering dairy farmers, intermediaries, consumers and other stakeholders in the dairy industry. The results reveal a significant fall in farmgate milk prices, disruption in transporting milk within the supply chains, labour shortages, rise in production costs and lack of operating capital. The demand for milk and milk products declined sharply during the pandemic. To dispose of the excess milk supply, dairy farmers turned to localized value chains catering directly to consumer households. Approximately half of the farmers lost almost one-third of their income from processed milk products like ghee and butter. The dairy farmers agreed to strengthen the dairy value chains through better integration of the stakeholders. The inability of the farmers to quickly shift to digital platforms for sales of milk and milk products during the pandemic calls for special capacity-building efforts.

Subject: Non-invasive method of melanoma detection on the skin surface through extraction of image features using modified CAT optimization algorithm
Keywords: Contour refinement, edge detection, melanoma, non-convex boundary, optimization algorithm.
Abstract: In this study, melanoma was detected at an early stage using modified CAT optimization algorithm (MCOA) based on non-convex boundary edge extraction, pixel size, shape and intensity variations on the skin. MCOA can detect skin cancer at an early stage by extracting the non-convex border of the affected region prevent cancer spread. Thus melanoma is curable when detected at an early stage. MCOA extracts image features and obtains non-convex boundaries of melanoma in the skin image. The non-convex boundary region leads to visualization of discriminative features of melanoma based on the region of interest and scaling. The proposed MCOA delineates the affected region through non-convex border extraction and edge detection. An accuracy of 85% was obtained in the detection of melanoma using MCOA, when compared to traditional algorithms.

Abstract: Reduced glutathione (GSH) is a biologically important component that plays a critical role in antioxidant activity. Praseodymium(III) complex with GSH was synthesized and the complex formed was characterized by FTIR, XRD, TGA and SEM analysis. Infrared studies provided information on the mode of complexation between the lanthanide metal ion and GSH. XRD and TEM analysis showed the nanocrystalline phase and irregular morphology of the complex. TGA thermogram indicated good thermal stability of the complex. The in vitro antioxidant and antibacterial properties of the complex were studied. The results suggest that the praseodymium(III) complex possesses antioxidant and antibacterial activity.

Abstract: Available empirical evidence for the association between soil-based interventions and economic returns in India reveals the following. First, integrated nutrient management (INM) is superior to balanced nutrient management (BNM) in terms of yield and economic profit for the cultivation of maize and soybean. Second, incentivizing the usage of INM rather than BNM is likely to provide a better yield and higher income to rice, wheat and potato farmers. Third, more studies on various crops are required to scientifically compare and reach a definite conclusion on the yield and economic returns from different types of fertilizer applications – INM, BNM and organic or biofertilizers. These findings have policy implications in India since the Soil Health Card scheme was centralized in 2015

Abstract: Sea anemones are brightly coloured marine invertebrates belonging to the order Actiniaria of class Anthozoa and phylum Cnidaria. Globally, more than 1000 species of sea anemones have been reported. However, in India only 54 species belonging to 40 genera and 20 families have been documented1 . Sea anemones can reproduce either sexually or by parthenogenesis. In sexual reproduction, external fertilization occurs followed by the development of planktonic planula larvae, which become single polyps. In asexual reproduction, the sea anemones divide by budding or binary fission.

Abstract: Calopogonium mucunoides has been widely used as a pasture legume, cover crop and nitrogen fixing plant in tropical regions of the world. The present study investigated the effect of different pre-treatments on germination per cent (GP), mean germination time (MGT), germination value (GV), peak value (PV) and germination index (GI) of C. mucunoides. Experiment was conducted in Complete Randomized Design with four replications of 25 seeds for each treatment and control (25 seeds × 4 replicates × control/hot water/acid scarification/sand scarification/growth promoters = 52 experimental units). Seeds were subjected to different pretreatments viz., Hot water soaking at 40°C, 60°C, 80°C, 88°C; acid scarification using conc. H2SO4 98% (1% (v/v), 3% (v/v), 5% (v/v); sand scarification, GA3 treatment (500ppm and 1000ppm); KNO3 treatment 0.1% (w/v), 1% (w/v), 3% (w/v). Results of germination parameters such as GP, MGT and GV were subjected to analysis of variance (ANOVA). Dunnett t (2-sided) statistical analysis and Post hoc Tukey HSD method was used for testing the significance between treatments. Results concluded that control seed produce the GP of 56% while sand scarification and hot water soaking of seeds enhanced the GP range from 80-97%.

Subject: Variation in Growth, Biomass Production and its Components in Eucalyptus Clones
Keywords: Biomass Production, Components, Eucalyptus Clones and Growth.
Abstract: Eucalypts are among the most widely cultivated forest trees in the world under a range of different climates for products that include pulp, paper fuel wood and solid wood products such as poles, furniture and construction timber. Large scale plantations have been raised in government owned and private farm lands; the planting is continuing. Productivity and profitability of plantations of Eucalyptus have been revolutionized with the development of genetically improved, fast growing and high yielding clonal planting stock of Eucalypts. Eucalypts clonal planting has been said to have advantages which includes quick provision of benefits associates with fast growth, short rotation for production of pulp wood (of around 70 t ha-1 in 6 years) ready marketing and easy establishment and less maintenance needs. Clonal planting one among the approach for management of water and nutrients compared to the other conventional strategies. Studies relating to clonal difference and evaluation for dry matter production will help to overcome productivity loss due to deficit rainfall and optimum utilization of available natural resources for higher wood production. The present study was carried out to test the hypothesis that there exists a clonal variation in growth, biomass production and components and the present study gives an insight in to clonal variation with reference to growth, biomass production and components.

Subject: Between tree Variation in Vessel Morphological Characterstics of Ten Different Candidate Plus trees (CPTs) of Ailanthus triphysa (Dennst.) Alston. (MATTI)
Keywords: Vessel Length, Vessel Area, Vessel Diameter, Vessel Frequency, CPTs, A. triphysa.
Abstract: In the present study vessel morphological characteristics viz., vessel length, vessel area, vessel diameter and vessel frequency of ten different Candidate Plus Trees (CPTs) was studied. All the parameters were found to be significantly different during analysis. The average vessel length was found to be 618.9 μm, average vessel area 48351.41μm2, average vessel diameter 289.71μm and vessel frequency 2no./mm2 respectively. the data obtained in the present study will be helpful to establish a correlation between vessel morphology and matchwood quality. Also the vessel morphological relation can be obtained between CPTs and progenies in future.
