Information on Non-coding RNAs in the alleviation of biotic stress in rice

Paper ID- AMA-03-02-2023-11987

Rice is the major staple food crop across the globe. Rice productivity is hindered by several biotic and abiotic stresses, which cause serious damage to plant growth and yield losses. Understanding the regulatory molecular events and their biological mechanisms, which are interconnected through the molecular interaction process to minimize the yield losses caused by the occurrence of stress factors, is of great importance. In this study, the data on experimentally curated stress-responsive miRNAs and lncRNAs in rice were collected from the literature and stored in a database. The chromosome map, bipartite network, and blast options were developed for miRNA. The basic features of miRNA (402) and LncRNA (4,543) include miRNA, miRNA ID, position, chromosome no, sequence, regulation, and protein function. For LncRNA, gene ID, chromosome number, gene regulation strands for abiotic stress and transcript ID, chromosome number, gene regulation strands for biotic stress, chromoMap network, and blast options were included in the database.The database can be efficiently used for genetic engineering experiments such as the development of CRISPR/cas9 construct and generation of transgenic plants and also for molecular breeding, which would facilitate the development of high-yielding rice varieties with broad-spectrum biotic and abiotic stress tolerance.

Assessing the Carbon Sequestration and Oxygen Release Potential of Trees and Shrubs under High Density Plantation

Paper ID- AMA-02-02-2023-11983

Mixed tree plantations can be a good silvicultural alternative for climate change mitigation. The carbon sequestration estimated in trees and shrubs from the previous study indicated that there are certain tree species with high ability to fix atmospheric carbon dioxide into tree biomass. In order to understand how carbon storage and allocation patterns vary among different plantation types, the present study was carried out to compare the performance of two different plantation sites (BSA 1: 14 species of 10 families and BSA 2: 14 species including 7 trees and 7 shrubs of 11 families). Based on the results, the highest biomass accumulation was observed in BSA 1(6.82 tonnes of biomass per ha per year) and the lowest mean biomass production was observed in BSA 2 (3.10 tonnes of biomass per ha per year). Likewise, the highest total carbon sequestration and oxygen release potential was recorded in BSA 1 (4.26 tonnes of carbon per ha per year, 11.36 tonnes of oxygen per ha per year). The results revealed that out of two study areas studied, the experimental site with tree species showed better performance when compared to the site planted with trees and shrubs. Azadirachta indica, Thespesia populnea, Pongamia pinnata and Terminalia catappa were the tree species that contribute for high carbon sequestration in the BSA 1. The present study suggest that selection of correct choice of tree species for plantation would enhance more carbon sequestration, high oxygen release and improved environmental quality.

Alleviation of physiological and biochemical attributes of rice cultivars by protectants under ozone stress

Paper ID- AMA-01-02-2023-11982

Elevated levels of tropospheric ozone (O3) can harm plants by inhibiting growth and production thereby posing a threat to environmental health and food security. As a consequence, developing novel strategies for crop protection against ozone has become critical. Ethylene diurea (EDU), is one of the most effective protectants, frequently utilised in various studies; nevertheless, the efficacy of other protectants is yet unknown. As a result, the purpose of this study is to evaluate the efficacy of EDU, neem coated urea (NCU), and ascorbic acid (AsA) in reducing ozone stress (100 ppb) in ozone tolerant (Anna (R) 4) and sensitive rice cultivar (TRY (R) 2) grown in an open top chamber. The results show that applying protectants was extremely beneficial in enhancing physiological characteristics and lowering malondialdehyde and proline levels in both rice cultivars, with the impact being significantly greater in TRY (R) 2 than in Anna (R) 2. The addition of 1% NCU increased the photosynthetic rate in Anna (R) 4 by 23.80 and 54.78%, respectively. In ozone tolerant and sensitive cultivar, the photosynthetic rate (20.15 and 50.21%), stomatal conductance (15.78 and 37.14%), and chlorophyll content (36.63 and 60.72%) were all increased by 1% AsA treatment. Moreover, in O3 sensitive cultivar, application of 1% NCU and AsA reduced MDA by 35.63 and 31.41%, and proline by 40.8 and 36.64% respectively. To conclude, the current study revealed that besides EDU, NCU and AsA are also superior in terms of protecting the plants from ozone stress.

MAIZE FARMER’S APPREHENSION ABOUT DIFFERENT MANAGEMENT PRACTICES ON MAIZE CULTIVATION IN NABARANGPUR, ODISHA

Paper ID- AMA-27-01-2023-11976

The current demand driven cultivation practices required a multipurpose crop like maize that is used for various purposes including food, feed, fodder, green cobs, sweet corn, popcorn, starch and several industrial products. A study was conducted with 90 farmers from nine villages of three blocks of Nabrangpur district revealed that the respondents have better knowledge on summer ploughing and cleaning of crop residue and stalks and FYM application are some basic activities of land preparation so that are well known to the farmers. Application of chemicals, preparation of furrows for water application like pre-sowing activities are not known to the maize farmers. The farmers have adequate knowledge about irrigation system provided during critical stages of growth which are emergence stage, weaning, initiation of ears, tassel visible, female flowering grain abortion limit stage and doughy grain stage are more prone to moisture stress. All the socio-economic attributes of the respondents except family size have significant and influence the knowledge level of the maize farmers.

Mortality Pattern of Ramnad White Sheep maintained at TANUVAS, RREC, Pudukkottai.

Paper ID- AMA-27-01-2023-11975

Mortality pattern in Ramnad White Sheep was studied for the period from 2014-16. The mortality rate was 14.5% in young stock and 3.09 % in adult. Among the systemic causes diseases of the respiratory system disorders affects (50%) in young stock and 100% in Adult stock followed by general systemic disease 25% in young stock whereas alimentary system affects the 16.66% in young and hepatic system affects 8.33% in young stock. The mortality rate was higher during north-east monsoon(50%) followed by winter (33.33%), Summer (16.66 %).
