Mitigating Fruit Cracking in Bael (Aegle marmelos Corr.) Fruits through Organic and Inorganic Nutrient Application and Mulching in Hot Arid Regions
This experiment assessed the effects of organic manures and inorganic fertilizers on bael fruit production, with a focus on mitigating fruit cracking in hot arid regions. The highest fruit yield of 41.65 kg per plant was achieved with the application of NPK, 60 kg FYM, and mulching with black polythene, followed by NPK + 60 kg FYM combined with crop residue mulching (35.26 kg/plant). This treatment also demonstrated superior fruit set, retention, and minimal fruit drop. Leaf nutrient analysis showed significant variations among treatments, with the highest nitrogen content (1.90%) observed in plants treated with NPK + 60 kg FYM and black polythene mulching, which correlated with increased fruit yield. The highest phosphorus content (0.73%) was also recorded in this treatment. In contrast, control plants exhibited lower nutrient levels (1.47% nitrogen, 0.41% phosphorus, and 1.12% potassium) and the lowest fruit weight (0.41 kg). Both organic manures and inorganic fertilizers contributed to an improvement in total soluble solids (TSS) content, with the highest TSS (47.15° Brix) found in fruits treated with NPK + 60 kg FYM and black polythene mulching. Effective nutrient and moisture management, supported by organic manures and mulching, significantly improved bael fruit yield and quality. This study focused on the importance of balanced nutrient supply and soil conservation techniques in enhancing bael productivity and mitigating fruit cracking in arid conditions.
Endoscopic screening of esophageal disorders in clinical cases of dogs.
Esophageal diseases are acute and causes weight loss, frequent vomiting are ongoing issues. It is preferable to offer these patients most precise diagnosis and to enable the proper treatment quickly to avoid serious consequences. This present study on “endoscopic Screening of esophageal disorders in clinical cases of dogs” was conducted at Veterinary Clinical Complex, Veterinary College and Research Institute, Namakkal, TamilNadu with the objective to screen the esophageal changes in the dogs with esophageal disorders with video-endoscope. Out of 7342 dogs, 42 dogs with symptoms suspicious of esophageal disorders were selected and subjected for detailed physical examination, and clinical examination. Out of 42 dogs, endoscopy was done in 12 dogs with esophageal disorders. Six apparently healthy animals brought for routine check up was studied for normal values of parameters under study. In this study, 0-3 years old dogs were highly affected with eso phageal disorders, the highest frequency of esophageal disorders was recorded in male dogs, Among the esophageal disorders, higher frequency of foreign bodies was recorded and retrieved in dogs followed by esophagitis, megaesophagus and tumour. Endoscope is the cutting edge instrument for the characterization of lesions involved in esophagitis by visualising and video recording of the observations is an inevitable tool for clinician for the evaluation of esophagus and post therapeutic review. Hence, for clinicians, endoscopy plays a versatile role in prompt treatment and prevention of consequences of esophageal disorders in dogs.
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.
