Study of groundwater potentiality in rainfed plateau of Chhattisgarh using remote sensing and GIS
The present investigation on ground water potential tracks through remote sensing and GIS techniques was carried out for geo-spatial multi-criteria approach. Due to uneven rainfall trend increases demand of below ground water in southern Chhattisgarh, this is urgently needed for sustainable resources of ground water. The dendritic to parallel drainage pattern of area shows showing branches of tree networks and low homogeneity and uniformity. The maximum irregular to moderate irregular surface mainly indicates the occurrence of groundwater. The maximum loss of runoff water does not permit infiltration to recharge zones under groundwater. Slope having 1-3% exhibits mainly flat to gentle considered a ‘good’ category for the groundwater occurrence owing to more favourable to capacity of infiltration of surface factor regarding long term retention of runoff water which indicates low potential for development of groundwater. The area posses 31% cultivated land, 15% concrete, barren scrub and forest scrub covers 12% each with 11% of moderately dense forest providing huge chance of extraction of groundwater round the year (except 2-3 months) in this rainfed region. Area with very high, moderate, poor and very poor groundwater potentiality comprises 2185.43 km2, 519.35 km2, 239.98 km2, 1084.90 km2 and 0.34 km2 which covers 54.23%, 12.89%, 5.95%, 26.92 and 0.01% area in the region, respectively. The surface morphology of the region is characterized mostly by typic haplusterpts (30%) and lithic ustorthents (21%) are major soil types with sensitivity analysis on basis of weightage for all thematic layers exhibits variation from the empirical weights in groundwater potentiality is most response to lithology is a paramount important parameter in assessing groundwater water potentiality and then lineament density, geomorphology, slope and drainage density are considered.
Change study on spatio-temporal dynamics of Jagdalpur city landscape of Chhattisgarh, India using remote sensing and GIS - A case study
An attempt has been made to measure and monitor spatio-temporal dynamics of Jagdalpur landscape, Chhattisgarh, India using urban plan maps (1981), topographical sheets (1981), temporal Landsat 5 Thematic Mapper data for the years 1990 and 2018. The spatial alongwith temporal change in land use pattern over 1990 to 2018 has been observed that the more area occupied by vacant lands, low dense forest and scrub forest with 19.8, 15.9 and 15.3%, respectively in imageries of 1990 which is changed with 2018, first three classes low dense habitat (21.9%), habitat (19.2%) and vacant lands (13.5%) occupied more area; however, lowest (6.3%) is under dense forest. These changes in land use due to more development of colony and expansion of Jagdalpur city in west and south direction as educational hub transforming large cultivated lands over the period of time. Analysis of low dense habitat areas show that significant area has been increased from 14.3 to 21.9 per cent of TGA during 1990 to 2018. The majority of habitats are in core area of city, whereas in the year 2018, area under these settlements has been increased considerably in all directions. Analysis of out skirt agricultural lands of Jagdalpur city indicates that the vacant lands mainly noticed in western and southern parts with an area of 13.5 per cent and rainfed rice occupies in conjunction of western and southern parts of city with 8.0 per cent area of TGA. 2000 onwards, the western part of city has been developed as educational hub and opening of Medical college in southern part gained momentum for constructing colonies and purchasing lands on vacant and cultivated lands. This situation gears up eastern part after NMDC at Nagarnar.
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.
