ABSTRACT
The aim of the study is to identify the suitable modified atmospheric storage condition required for long term storage of groundnut (Arachis hypogaea L.) variety TMV (Gn) 13. The experiment was conducted during 2022 at Department of Seed Science and Technology, Tamil Nadu Agricultural University, Coimbatore. The groundnut pods and kernels were subjected into different storage conditions viz., pods stored in gunny bag, kernels stored in gunny bag, kernels stored in polythene bag, kernels stored with N?gas and kernels stored in vacuum conditions. The results revealed that pod storage recorded the maximum germination percentage (73%), root length (14.5cm), shoot length(14.3cm), dry matter production (3.47 g 10 seedlings -1) and vigour (2136). Similarly, enzymes viz., dehydrogenase( 0.72 OD value), peroxidise (1.29U mg?¹ protein min?¹), alpha amylase (13.60mg maltose min-1) and catalase activity (1.253 µmolH?O? min?¹g?¹ protein) were also maximum in pod storage with minimum harmful effect of pest(0.6%) and fungus incidence(17%). The nitrogen storage conditions also have maximum enzyme activity viz., dehydrogenase (0.64 OD value), peroxidise (1.24U mg?¹ protein min?¹), alpha amylase (13.58 mg maltose min-1) and catalase activity (1.220 µmolH?O? min?¹g?¹ protein) with minimum harmful effect of pest (0.6%) and fungus incidence (20%). Present study, it is concluded that groundnut kernels stored under modified atmospheric storage i.e. nitrogen gas storage can maintain the seed longevity by minimizing the deterioration process in groundnut equally as that of pod storage. Further, it will helps to minimize the expenditure towards transport and storage.
ABSTRACT
Watermelon (Citrullus lanatus) is one of the important fruit crops cultivating in India. Adoption improved production technologies in watermelon cultivation is not followed by majority of the farmers. Tamil Nadu Irrigated Agriculture Modernization and Water Bodies Restoration and Management (TN IAMWARM) is a unique World Bank funded project implemented with the prime motive of increasing the productivity of irrigated agriculture in the state of Tamil Nadu. Accordingly the TNIAMWARM project was implemented in Villupuram district through Krishi Vigyan Kendra, Tindivanam with one of the interventions that dissemination of precision farming technologies in watermelon cultivation to improve its productivity. The present study analysed the factors influencing adoption of Precision farming technologies in Watermelon cultivation. Most of the respondents gave first preference to the higher yield (Mean score - 72.2) as their reason of adoption of precision farming technologies in tomato cultivation followed by yield increase, provision of subsidy. Under external factors, the respondents gave first rank to TNAU scientists (Mean score - 79.42) as the influencer to adopt the precision farming technologies in watermelon cultivation. Further, the respondents expressed that the influence of executing TNIAMWARM project (79.25) exerted some compulsion on them which was deemed as a social factor in the adoption of Precision Farming technologies.
ABSTRACT
This study examined the Knowledge level of Paddy farmers on Climate Change the Nagapattinam district of Tamil Nadu state in India. It is situated in the coastal area and is very often subjected to natural calamities which were mainly reflected in the Paddy cultivation to the worst status. The ex-post facto research design was used in this research study. A sample size of 200 was fixed for the study. The data were collected with the use of a well-structured and pre tested interview schedule for farmers covering all the aspects of knowledge on Climate change. The respondents’ knowledge level of climate change was measured by designing exclusively the knowledge test. The study revealed that more than half of the respondents (55.00%) had a medium level of knowledge of climate change. Nearly one-third (32.50%) of the respondents had a high level of knowledge and a lesser number of respondents (12.50%) were found to be under the category of low- level knowledge. Educational status, farming experience, contact with extension agencies, information seeking behaviour, social participation, innovativeness, risk orientation and awareness had shown positive and significant associations with paddy farmers knowledge and these variables contributed to improving the knowledge level of the Paddy farmers on climate change. They had knowledge of changes in the rainfall patterns, extreme climatic events, changes in the crop growths stages, ground water table and pest and disease outbreaks but the famers don’t have enough knowledge on climate change adaptation strategies in Paddy cultivation with respect to tackle the problem of salinity, sodicity and effects of humidity in grain filling to cope up with climate change. Hence, it is recommended that special training programmes may be frequently offered in the study area to improve the knowledge and skill of the farmers on climate change.
ABSTRACT
Background: Dermatophytosis is a clinical condition caused by a fungal infection of the skin in humans and domesticated animals. Currently up to 20% of the population may be infected by one of the dermatophytes. Objective: To isolate and identify the fungal agents from clinical samples of dermatophytosis patients in and around kakinada. Materials and Methods: Clinical samples from 150 patients were subjected to potassium hydroxide (KOH) examination and culture. Causative organisms are identified macroscopically and microscopically. Statistical analysis was done by chi square test. Results: Out of 150 samples, 120 shown KOH positive and 66/120 (55%) samples were culture positive. Of these isolation rate of dermatophytes was 70/120 (58.3%) among these, 66 were Trichophyton species, 3 were Microsporum species, 1 was Epidermophyton floccosum. T.rubrum was the major isolate about 35(29.1%) strains. The male to female ratio of the positive cases was recorded as 11:3. The most effected age group was 21-30years (40%) followed by 31-40 years (28.6%). Conclusion: It may concluded from the present study that Tinea corporis is more frequently encountered condition followed by Tinea cruris. T.rubrum was implicated as major predominating species followed by T.mentagrophytes. Unhygienic conditions among low socioeconomic group, frequent migration of laborers, workers, hot and humid climatic conditions may be some of the contributing epidemiological factors. The study signifies the importance of mycological examination of dermatophytoses samples for effective management and also for epidemiological studies.
