Soil Carbon Dynamics in Diverse Cereal-based Land Use System under Agro-climatic zone-IIIB (South West Alluvial Plain), Bihar, India
Land use management exerts a tenacious impact on soil organic carbon (SOC) dynamics; however, the impact varies with climate, soils, and management practices. Therefore, an in-depth understanding of changes in SOC pools and its fractions is necessary to adopt efficient land use planning to reduce carbon (C) emissions for sustainable soil management in the N Eastern region of India. The present study was planned accompanying with six land use viz., L1 (Rice-Wheat-Moong), L2 (Rice-Lentil-Moong), L3 (Rice-Chickpea-Moong), L4 (Rice- Maize), L5 (Rice -Potato-Maize) and L6 (Maize-Wheat-Moong), respectively. The representative soil samples in a four replication were collected and analyzed through standard procedure. The findings of this study revealed that the soils of the study area belong to the silty clay textural class content, and various carbon fractions were observed in decreasing trends viz., Non-labile (NL)>Less-labile (LL)>Labile(L)> and Very-labile (VL), respectively. The maximum accumulation of organic carbon fraction was observed at surface layer (0-5cm) due to exiistance of voluminous fine root compared to sub surface layer except SIC (soil inorganic carbon) fraction. Meanwhile, inclusion of legume in cereal based cropping system play key role to enhance TOC (Total Organic Carbon) in the soils. Whereas, in case of biological attributes, dehydrogenase (DHA) activity varied from 32.13 to 30.57 µg TPFg-1 soil hr-1, and highest level of activity was observed in the surface layers. Flurorescine diacetate (FDA) activity and MBC varied from 20.86 to 17.52 mg fluorescein g-1 soil hr-1 and 128.63 µg g-1 to 136.20 µg g-1.
Extent of Adoption of Guava Cultivation Practices among Farmers of Haryana
The present study was carried out in Haryana, India, to delineate the association between the adoption of the Guava cultivation practices and the independent variables of the farmers adopting guava cultivation. Personal conversations with the farmers served as the method for gathering the data. The sample size for the study contained 120 respondents. Analysis methods used to examine the study data included correlation, multiple regression, frequency, percentage, WMS, and rank. The selected independent factors accounted for 22.90% of the variation in the farmers' adoption of guava farming techniques., according to the coefficient of determination (R2). Some constraints were faced by the farmers, viz., fluctuations in market prices, high post-harvest losses, chances of theft, threats from wild and stray animals, and poor marketing in the local area. Overall, the study suggests that the government should establish proper cold storage facilities, provide MSP to all horticultural crops and establish proper marketing channels in rural areas.
Effect of sage and chameleon on the physico-chemical and organoleptic properties of pork sausage
Meat products with enhanced phyisico-chemical and organoleptic properties can be developed by incorporating various herbs. Attempt has been made in the present study to analyze the physico-chemical properties of two herbs viz., sage and chameleon and products developed incorporating these herbs. Both fresh sage and chameleon were found to have good amount of Fiber content, β-carotene, essential oil and minerals. Chameleon was found to have significantly higher content of flavanoid (64.20 mg QE/g) as compared to sage (29.60 mg QE/g). Pork sausage incorporated with sage has resulted to have significantly highest fiber content (7.56%) as compared to the pork sausage incorporated with chameleon (2.31%) and plain sausage (1.57%). Incorporation of chameleon in pork sausage has resulted in significantly higher flavonoid content (35.22 mg QE/g) as compared to the pork sausage incorporated with sage (11.62 mg QE/g). Further, the resultant products were found with increased macronutrients such as K and Ca upto two-fold and ten-fold, respectively. Pork sausage incorporated with sage has scored comparatively higher value in terms of texture, juiciness and tenderness as compared to sausages incorporated with chameleon and control sausage which resulted in higher overall acceptability of the products.
Epidemiological Analysis of Weather Parameters on Leaf Spot and Flower Blight (Alternaria tagetica) Disease in Marigold cultivation under North Western Himalayan Region
Floriculture has emerged as a lucrative source of income for farmers and is experiencing significant growth in the Jammu Valley of the North Western Himalayan region. Marigold (Tagetes erecta L.) stands out as a major ornamental crop cultivated in agro-climatically diverse areas, subjecting the plants to various abiotic and biotic stresses. Among these stressors, leaf spot and flower blight caused by Alternaria tagetica pose a substantial economic threat. Therefore, conducting periodic surveys to assess disease incidence and severity becomes imperative. Fortnightly surveys were carried out in key marigold-growing areas of Jammu, including Jammu, RS Pura, Bishnah, and Akhnoor block in Jammu district. The findings revealed an average disease incidence of 49.90% and 49.40% during the years 2017-18 and 2018-19, respectively. The impact of plant age on disease progression indicated that maximum leaf spot severity reached 57.50% and 58% in 2017-18 and 2018-19, respectively. Similarly, the maximum flower blight incidence recorded was 43.75% and 43.60% during the same periods, highlighting a correlation between disease development and plant age. The study underscored the significant role of environmental parameters—temperature, relative humidity, and rainfall—in disease development. During 2017-18, these parameters accounted for 51.0% and 94.2% influence on leaf spot and flower blight disease, respectively. In 2018-19, the respective percentages were 71.1% and 92.9%, confirming the impact of environmental factors on disease dynamics. The field experiment further validated these findings on the susceptible cultivar Pusa Basanti. Understanding these dynamics is crucial for developing effective strategies to mitigate the economic losses caused by leaf spot and flower blight in marigold cultivation in the North Western Himalayas.
Effectiveness of Farmers Fair in Transfer of Technology: A study in GBPUA&T, Pantnagar
Farmers fair also popularly known as ‘Kisan Mela’ are in subsistence for a long time. The main purpose of organizing such an event is to create awareness among the visitors about new technologies developed by researchers, primarily from the Government sector, agricultural and allied research centers, and State Agricultural Universities. In recent years, farmers' fairs have emerged as crucial instruments for disseminating cutting-edge agricultural technologies to farmers. The primary objective behind organizing these events is to raise awareness among attendees about the latest technologies developed by researchers, predominantly from the government sector, agricultural and allied research centers, and State Agricultural Universities (SAUs). Farmers fair also helps farmers in enhancing their knowledge of new schemes or programs. The study was undertaken to know the perception of farmers about usefulness of farmers fair. The study was conducted at G.B. Pant University of Agriculture & Technology, Pantnagar, involving 120 randomly selected farmers visiting the fair. The findings indicated that a good majority of participating farmers perceived that information received at Kisan Mela on Agricultural implements and machines, seed storage and processing, high yielding seed varieties, information on fertilizers, mushroom cultivation, dairy and animal husbandry, irrigation method and organic farming was highly useful.
