https://journals.saaer.org.in/index.php/jae/article/view/687
<p>Plants and insects have been living together for more than 350 million years. In co-evolution, both have evolved strategies to avoid each other’s defense systems. This evolutionary arms race between plants and insects has resulted in the development of an elegant defense system in plants that can recognise the non-self-molecules or signals from damaged cells, much like animals. It activates the plant’s immune response against the herbivores. Differences in genotypes of plant characters may affect insect-plant herbivore interactions, and variations in genotype traits are responsible for modifying the bottom-up effects. Recent evidence shows that the simultaneous occurrence of abiotic and biotic stress can positively affect plant performance by reducing the susceptibility to biotic stress, a positive sign for pest management. Plant responses to these stresses are multifaceted and involve copious antibiosis, physiological, antixenotic, molecular, molecular and cellular adaptations. Plants with antibiosis characteristics such as flavonoids, phenols, tannins, alkaloids, etc., may cause reduced insect survival, prolonged development time, decreased size and reduced new generation fitness. Quality and quantity of constitutive secondary metabolites production is species as well as cultivar specific and can be expressed as the signature of a particular plant or species and leads to the phenomenon of host-plant resistance. Hence, such plant resistance mechanisms have been effectively and widely used for managing insect pests in fields of underutilized crops. Natural defences are mediated through plant characteristics that affect insect biology, such as mechanical protection on the surface of the plants (<em>e.g</em>., hairs, trichomes, thorns, spines and thicker leaves) that either kill or retard the development of the herbivores. These phenomena of host plant resistance to insects can be exploited for the development of resistance crop cultivars which readily produce the inducible response upon mild infestation and can perform as one of the integrated pest management for sustainable crop production.</p>SM HaldharB SinhaBR ChoudharyD SinghJ KonsamN Thaochan

https://journals.saaer.org.in/index.php/jae/article/view/688
<p>Fall Army Worm (<em>Spodoptera frugiperda</em>), with the traits of devastating, voracious, polyphagous nature had recently imposed a global threat. Possessing these traits, this pest constituted a threat to global food security by ambushing more than several host plant species. To tackle this pest, insecticide management approaches was used initially. Later, with a better comprehension of the dynamic biology of the pest, such as their long migration capability, their ability to develop resistance against insecticide and the adverse effects of pesticides on human and the environment, an alternative strategy which is environmentally safe <em>i.e., </em>biological control approaches that is effective and low-risk is laid emphasis. A rich diversity of microbial populations which have the ability to infect the pest to a certain degree in nature remains untapped, and if so, identification of high virulence and productive strains within the population is lacking hitherto. This review focused on the information regarding the scenario of the occurring pest and its damaging nature to the host plants and microbial agents with their surplus potentialities along with the mode of interactions with the insect pest and self-perpetuating nature and their boon of disarming nature. The details of each microbe <em>viz.,</em> fungi, bacteria and viruses that possess the traits of controlling the pest naturally are briefed with an insight into molecular information, present findings, constraint and future prospects.</p>B SinhaSM HaldharK ChakrapaniCN NidhiZ RalteB WangkhemJ Konsam

https://journals.saaer.org.in/index.php/jae/article/view/697
<p>Biomass is an abundant and renewable resource in India, with vast potential for use in energy production, agricultural applications, and waste management. The country has made significant strides in developing and utilizing biomass resources for various purposes in recent years. One of the primary uses of biomass in India is for energy production. Biomass fuels, such as wood chips, agricultural residues, and municipal waste, are used in rural areas for cooking and heating. Additionally, the government has implemented policies and initiatives to promote the use of biomass for electricity generation. Biomass-based power plants have been established nationwide, with a total installed capacity of over 9,000 MW. Biomass is also used in agricultural applications in India. The country is a major producer of sugarcane, and bagasse, a byproduct of sugarcane processing, is commonly used as a feedstock for producing biofuels and biogas. Additionally, farmers are increasingly using biomass-based fertilizers and pesticides to improve soil health and reduce chemical inputs. Regarding waste management, biomass is a valuable resource for converting organic waste into useful products. Anaerobic digestion and composting are popular methods for treating organic waste, with the resulting biogas and compost being used for energy generation and agricultural applications, respectively. Overall, biomass is an essential resource for India, providing energy, supporting agriculture, and promoting sustainable waste management practices. With continued investment and innovation, biomass has the potential to play an even more significant role in the country's energy and agricultural sectors in the coming year.</p>A PrakashK Lal

https://journals.saaer.org.in/index.php/jae/article/view/698
<p>Organic waste materials <em>viz</em>., coir pith, rice husk, and water hyacinth were studied in the batch experiments to evaluate their potential for mercury removal from wastewater. Five pH (4,5,6,7,8) and five different contact times (1,2,4,6,8 hours) were studied with a constant mercury concentration of 0.1 ppm. SEM (Scanning electron microscopy-energy dispersive spectroscopy) and FTIR (Fourier transform infrared spectroscopy) were used for characterizing the biochars <em>i.e.</em>, rice husk biochar (RHBC), coir pith biochar (CPBC) and water hyacinth biochar (WHBC), used for the experiment before and after adsorption studies. Adsorption capacities of each different biochar used for the experiment varied due to their wide range of surface area as well as different shift patterns in the FTIR. Based on the experimental results, among the three adsorbents used for mercury removal from wastewater, coirpith biochar (CPBC) has a maximum removal efficiency of 46.2% followed by rice husk biochar (RHBC–44.8%) and water hyacinth biochar (45.6%) with 6 hours of contact time.</p>K SuganyaR SunithaM MaheswariR RizamE Parameswari

https://journals.saaer.org.in/index.php/jae/article/view/700
<p>Cashew (<em>Annacardium occidentale</em> L.) is a hardy and golden crop of arid regions, and the pseudo fruit, cashew apple is a vital source of sugars and vitamins that is discarded as a waste during cashew nut processing. Cashew apples start fermenting soon after the harvest, and due to the presence of a wide spectrum of polyphenols and tannins, the change of colour of cashew apples leads to an unappealing marketability and storage stability. The present study is aimed to rapid identification of different spoilage yeasts and to identify them using MALDI-TOF Mass Spectroscopy. Spoilage yeasts like <em>Candida krusei, C. tropicalis, Pichia </em><em>norvegensis, Brettannomyces bruxellensis </em>were the spoilage yeasts found to have high confidence score values of 2.00 - 3.00 with high consistency.</p>G GayathryP MaheshwariR ArtheeAsangeethaKjothilakshmi

https://journals.saaer.org.in/index.php/jae/article/view/711
<p>Lettuce (<em>Lactuca sativa</em> L.) belongs to the family Asteraceae and is known as a leafy salad vegetable. It is rich in vitamins like Vitamin A and C, and also a good source of minerals such as iron, sodium, calcium <em>etc</em>. It is more popular in temperate regions and also performing well under subtropical climatic conditions during the winter season. Therefore, the present investigation was carried out to identify the suitable variety of lettuce for higher yield and quality under subtropical climate. The experiment was conducted with five treatments replicated thrice. Seeds of these five lettuce varieties viz., Tango, Bingo, Summer Star, Grand Rapid and Black Rose were sown in portrays prefilled with a combination of media made of coco peat, vermiculite and perlite in the ratio 3:1:1. After thirty days plants were plugged out and transplanted under field condition to study the performance of lettuce varieties. Among the studied varieties, the maximum yield (191.44 q/ha) was recorded with the variety Summer Star which was at par (190.32 q/ha) with the Bingo variety, followed by (129.50 q/ha) in Tango and the least (85.51 q/ha) by Black Rose. However, vitamin C content and total carotenoid content were significantly found highest (15.98 mg/ 100 g) and 8.06 mg/ 100 g in the Black Rose variety, respectively. Tango variety observed maximum chlorophyll ‘a’ (5.85 mg/ g FW), ‘b’ (2.01 mg/ g FW) and total chlorophyll (7.85 mg/ g FW) content among studied lettuce varieties.</p>A SahilSR SinghK KumarJ N TiwariN Mukesh

https://journals.saaer.org.in/index.php/jae/article/view/726
<p>A functional decision support system (DSS) was developed through optimising values of parameters favour faster growth and development of tissue cultured plantlets of date palm and suppression of disease infection. The programming of control devices was further managed based on the ambient environmental conditions, which required variable simulation periods and a plan for controlling of all systems for maintaining the greenhouse environment. During the process of plant hardening, the plants were infected by Graphiola leaf spot <em>(Graphiola phoenicis</em>)<em>. </em>The moderate temperature, and high humidity inside the greenhouse, accompanied by short days and frequent occurrence of fog during winter months, favoured the development of smut infection. It is required to manage an extended photoperiod for 16 hours with 15000 lux light intensity provided by white fluorescent tube lights and incandescent bulbs inside the greenhouse. The integrated practices of enhanced photoperiod and light intensity under the greenhouse in combination with fungicides application to plants were found very effective in suppressing the intensity of the disease and its adverse effects on the plants. Using this decision support system (DSS), the tissue cultured date palm plants cv. Barhee has been successfully hardened and managed disease and transplanted in the field for further studying establishment, survival, plant growth and fruiting-related parameters.</p>D SinghK KumarPN SivalingamC RamGB PatilN Subhash

2023-11-102023-11-1017757910.58628/JAE-2317-313The ocean carbon pool: a vital component of the global carbon cycle
https://journals.saaer.org.in/index.php/jae/article/view/770
<p>The global carbon cycle is an integral part of the Earth System. Of the land, atmosphere, and ocean components of the global carbon cycle that exchange carbon on the timescales of decades to centuries, the ocean contains more than 90% of carbon. The ocean carbon pool represents a critical component of the Earth's carbon cycle, playing a pivotal role in regulating atmospheric carbon dioxide (CO<sub>2</sub>) levels and influencing climate dynamics. The exponential increase of total anthropogenic CO<sub>2</sub> emissions in the industrial era implies the ocean's uptake has increased exponentially, reaching 2.5 ± 0.6 Pg C yr<sup>-1</sup> for 2009-2018. Without the ocean and land sinks, atmospheric CO<sub>2</sub> levels would be close to 600 ppm. The ocean carbon pool comprises dissolved inorganic carbon (DIC), organic carbon, and particulate organic matter, collectively responsible for the sequestration and release of carbon into the atmosphere. Phytoplankton, the microscopic marine plants, play a fundamental role in the oceanic carbon cycle by photosynthesizing and fixing atmospheric CO<sub>2</sub> into organic matter. This organic matter can be transferred to the deep ocean through the biological pump, further contributing to the storage of carbon in the form of sinking particles. The bulk of the global ocean margin represents a carbon sink of ~0.1-0.2 Pg C. Oceanic processes, such as ocean circulation and upwelling, help redistribute carbon from surface waters to the deep ocean. The solubility pump, which is driven by changes in temperature and salinity, also affects the solubility of CO<sub>2</sub> in seawater. These natural processes work to mitigate the increase in atmospheric CO<sub>2</sub> concentrations and help regulate global temperatures.</p>P KalaiselviRM DeviE ParameswariSP SebastianV DayamaniT Ilakiya

2023-11-102023-11-1017808410.58628/JAE-2317-314Economic benefits of animal pollination to Punjab agriculture
https://journals.saaer.org.in/index.php/jae/article/view/771
<p>Indian Punjab is gradually becoming the promised land of diversified farming with beekeeping as an important component, as farmers are looking for ways to get out of the paddy-wheat cycle. With this consideration, the present study estimated that the contribution of animal pollinators toward state agriculture. The economic value due to pollination service (EVP) was Rs 1391.2 crores forming about a 2 per cent share in the EV of output from state agriculture. Among the entomophilous crops, the insect pollination was essential for 2; great for 3; modest for 4 and of little importance to another 4 crops. About 42 per cent of the non-animal pollination-dependent crops accounted for a major share in the EV <em>i.e.</em> 97.87 per cent of the total agriculture output of the state. The share of cereals was the highest in the EV <em>i.e.</em> 86.79 per cent followed by vegetables (5.50%), fruits (5.32%), cotton (1.69%), sugarcane (0.35%), oilseeds (0.32%) and gram (0.01%) while based on dependence rate, the EVP was the highest in fruits (49.78%) followed by vegetables (21.49%), cotton (19.85%) and oilseeds (8.88%) and there existed no EVP for cereals and sugarcane and gram. The crops having great dependence on pollination contributed the maximum (Rs 741.13 crore) <em>i.e.</em> about 53 per cent to the EVP and about 1 per cent to the EV in the state agriculture. There is a strong need to realize the potential of this segment and formulate crop and commodity-specific strategies for optimum utilization of animal pollination inputs followed by crop diversification to high-value commodities. Punjab agriculture faces challenges on the production front and increased production cost needs such as “micro concepts” with “macro-economic” impacts.</p>Sangeet Ranguwal
