Turmeric Price Dynamics in the Eastern Himalayan Region: A Case Study of Meghalaya
This study explores the trends in price variability for turmeric in Meghalaya's regulated market, utilizing data provided by the State Agricultural Marketing Board. The analysis focuses on the Mawiong Market, managed by the Mawiong Market Committee, which serves as a key hub for agricultural commodities in the region. The trend line equation y=1.0854x−34607y = 1.0854x - 34607y=1.0854x−34607 indicates an upward trend, necessitating further analysis to confirm its statistical significance. The study employs statistical methods, including the Sense Slope estimate and Mann-Kendall's test, to analyze turmeric price dynamics over ten years from January 2014 to February 2024 to analyze significant changes. This non-parametric test is widely used to detect monotonic trends in time series data. The Mann-Kendall test revealed a z value of 2.5006 with a p-value of 0.0124, confirming a statistically significant increasing trend in turmeric prices over the analyzed period. The Sen's slope estimate indicated a positive slope of 51.71, suggesting a gradual increase in prices over the period. Correlation and regression analyses reveal that minimum temperature significantly influences turmeric prices, indicating its pivotal role in shaping price dynamics in Meghalaya. In contrast, maximum temperature and rainfall show weak and statistically insignificant effects. These findings highlight the need for adaptive agricultural policies and market stabilization measures to address climate-driven price variations. To stabilize market dynamics, policymakers should enhance price monitoring systems, provide support to turmeric producers, and strengthen marketing infrastructure to ensure the resilience of Meghalaya's turmeric market amidst ongoing fluctuations.
Population growth parameters of invasive fall army worm, Spodoptera frugiperda on castor in India
The Fall army worm, Spodoptera frugiperda (J. E. Smith, 1797) (Lepidoptera: Noctuidae) is a polyphagous pest native to the tropical and subtropical regions of America. In Asia, S. frugiperda was first detected in the southern state of Karnataka, India. Since the S. frugiperda occurrence, limited information is available on its biology in different host plants. Host plants play a crucial role in the life cycle of insect and may be used for pest management strategies. Therefore, the study aimed to investigate the reproductive, developmental and population growth parameters of S. frugiperda on castor and maize under laboratory conditions. According to the findings, significant variations were observed in all the reproductive parameters on both the host plants. The egg, larval, pupal duration and adult longevity of S. frugiperda significantly prolonged on castor as compared to maize. Minimum and maximum survival of S. frugiperda were noticed in castor and maize. Both the tested plants, castor had lower values of population growth parameters (net reproductive rate R0, intrinsic rate of increase Rm and finite rate of increase λ) and longer generation time Tc than that of maize. This research suggested that castor can contribute to the development and spread of this invasive pest in the absence of its regular host (maize).
Analysis of job characteristics of the Veterinarian at the Government Veterinary Centre from the state of Tamil Nadu
A study was conducted to assess the job characteristics of Veterinarians from the Government Veterinary Center of Tamil Nadu. Factor analysis with principal component approach (PCA) was used to determine the relationship among indicators for assessing livestock production potentials of the districts of Tamil Nadu. An index was constructed and the relative position of districts was identified. Based on index scores, the districts were classified into three categories: highly progressive, moderately progressive, and least progressive districts in the livestock sector. Two districts from the highly progressive category and two districts from the least progressive category were chosen. To get the nature of the nature of job performed by Veterinarians working at the Government Veterinary Centre, 48 veterinarians (12 from each district) were selected purposefully. The study employed a structured survey method to assess the frequency and ranking of job activities performed by veterinarians in Government Veterinary Centres (GVC). Data were analyzed using mean score rankings to determine the most and least performed tasks. The study found that veterinarians in Government Veterinary Centres primarily perform medicinal and gynecological services, with limited engagement in farmer communication. Strengthening veterinarian-farmer interactions and outreach efforts could enhance livestock healthcare and farming support. The study also found that Veterinarians need a balanced focus on curative, administrative, and extension roles. Training, resource allocation, and reduced administrative burdens can enhance efficiency, while improved extension services can strengthen farmer communication.
ALTERNATE SYSTEMS OF MEDICINE IN ANIMAL HUSBANDRY
Ethno-veterinary practices and homeopathic approaches in animal husbandry offer alternative or complementary methods to conventional veterinary care, often rooted in traditional knowledge passed down through generations. Ethno-veterinary practices encompass a wide range of local, indigenous, and cultural practices for animal health management, utilizing medicinal plants, herbal remedies, and various therapeutic interventions that are specific to particular communities or regions. These methods are often based on long-standing experience and observation, reflecting a deep connection between humans, animals, and the natural environment. Homeopathic practices, on the other hand, apply principles of homeopathy, a system of alternative medicine that uses highly diluted substances to stimulate the body's healing responses. Homeopathic treatments in animal husbandry are employed to address a range of health issues, from acute conditions to chronic diseases, with a focus on individualized care and holistic treatment. Both approaches are gaining attention in modern veterinary practices due to their potential benefits, such as reduced reliance on pharmaceuticals, lower costs, and an emphasis on sustainability. Despite their promising applications, challenges such as limited scientific validation and the need for more research remain. This abstract highlights the relevance and integration of ethno-veterinary and homeopathic practices in contemporary animal husbandry, examining their potential advantages, limitations, and opportunities for future development.
Physiological and Biochemical Characterization of Variegation in Areca catechu Linnaeus Populations from South Karnataka, India
Variegation is the presence of discrete markings of different colours on plant parts and is of economic and scientific importance in ornamental crops. But variegation is rarely reported in perennial trees, especially in palms. This study reports the presence of variegation in areca palm, Areca catechu Linnaeus, an economically important plantation crop. The variegation traits were identified in the areca palms of Mangala and South Kanara Local (S.K. Local) varieties grown in Southern Karnataka, India. The variegated and non-variegated regions of the variegated leaves as well as the normal leaves were analysed for physiological parameters and the nuts of variegated and normal palms were studied for important biochemical constituents. The variegated and normal palms exhibited significant difference both physiologically and biochemically. The yellow regions of the variegated leaves lamina exhibited low photosynthetic rate, stomatal conductance, transpiration rate and chlorophyll index when compared to green region of variegated leaves as well as the normal leaves in both Mangala and S.K. Local varieties. The photosynthetic rate, stomatal conductance, transpiration rate and chlorophyll index of Mangala and S.K. Local varieties recorded in yellow regions of the variegated leaves were 1.1966 µ mole m-2s-1 and 1.7332 µ mole m-2s-1, 0.1028 mole m-2s-1 and 0.0683 mole m-2s-1, 2.3482 m mole m-2s-1 and 1.9983 m mole m-2s-1 and 16.7667 and 22.8333, respectively. The photosynthetic rate, stomatal conductance, transpiration rate and chlorophyll index of Mangala and S.K. Local varieties recorded in non-variegated leaves were 3.4348 µ mole m-2s-1 and 3.8569 µ mole m-2s-1, 0.2228 mole m-2s-1 and 0.1050 mole m-2s-1, 3.8307 m mole m-2s-1 and 2.9371 m mole m-2s-1, 67.00 and 66.20, respectively. However, stomatal resistance was observed to be low in green regions of variegated (1.4067 s cm-1 and 5.0333 s cm-1) and non-variegated leaves (1.7833 s cm-1 and 1.7833 s cm-1) in both the varieties when compared to yellow regions (8.3667 s cm-1 and 10.8667 s cm-1). Biochemical constituents like total sugar, total phenolics, non-tannin phenolics and antioxidant potential in terms of reducing power using CUPRAC and FRAP methods indicated wide variation between variegated and non-variegated nuts. Variegated plants are often valued for their aesthetic appeal. By understanding the physiological and biochemical basis of variegation in Areca catechu L., breeding programs could be devised to develop strategies to manipulate variegation so as to exploit the trait in an aesthetic point of view as well as to facilitate conservation efforts and formulate horticultural practices for cultivating these variegated palms. Further studies are warranted for better understanding of the mechanism, as well as the factors responsible for the variegation trait in Areca catechu L.
