CHARACTERIZATION AND COMPARARTIVE STUDY OF CHEDDAR CHEESE FROM NILI-RAVI BUFFALO MILK AND SAHIWAL COW MILK
Cheese is replacing the proportion of conventional dairy products in urban and semi-urban areas, owing to its health advantages, usage, longer shelf life, and so on. Cheddar cheese is a popular cheese because of its strong flavour and usage in a variety of culinary recipes. Accelerated cheese ripening is one of the scientific ways for reducing ripening time without compromising quality, which might be of significant commercial importance. In terms of flavour and ripening, cheddar cheese made from the indigenous Sahiwal cow breed was comparable to that made from the Nili Ravi buffalo breed. The texture of buffalo milk cheddar cheese, on the other hand, was relatively firm. Both cheeses were equivalent in terms of yield and physico-chemical characteristics. The inclusion of adjunct culture, which is typical of cheddar cheese in both types of milk, enhanced the flavour, body &texture, and mouth feel. The physicochemical and microbiological parameters remained within the FSSAI guidelines throughout the experiments.
Effect of Zero tillage potato in yield and managing climate change in Begusarai
Zero tillage potato is increasing attention for cropping system intensification in the India. Zero tillage potato with the use of rice straw mulch reduces the worst effects of climate change, soil salinity, and increases productivity with minimum input. A trail was conducted at Krishi Vigyan Kendra, Begusarai, Bihar during Rabi 2022-23 just after harvesting of paddy. The trail comprised two treatments viz., Zero tillage potato method and Conventional method with three replications. The variety used for both the treatments was Kufri Bahar. Trail result shows that the highest yield of potato was obtained in zero tillage method (236.50± 7.91 q/ha) as compared to the conventional method (201.0±2.13 q/ha) that was 17.66% more. The benefit cost ratio was highest in zero tillage i.e. 2.4, which was 41.17% higher than the conventional method. In an economic view, the result of study showed zero tillage method is cost effective compared to conventional method, it is saving money in irrigation, weeding, field preparation etc. Zero tillage method improves the tuber formation and reduces the chances of early blight as well as late blight disease because of no tillage and mulching compared to the conventional method.
Assessment of the reproductive outcome of sex-sorted semen in Indian crossbred cattle
Flowcytometry-based sorting of X-bearing sperms helped to produce calves of desirable sex calves and was successfully used in the livestock industry worldwide. In India, the usage of this technique is minimal, and there is little information about the success rate of sex-sorting technology. We examined the quality of commercially procured sex-sorted X-bearing sperms in this work by assessing X and Y sperm population per straw, live and dead percentage, acrosomal integrity, Sperm Chromatin Structure Assay (SCSA), (Reactive Oxygen Species) ROS / OS, Osteopontin (OPN), and Ubiquitin (UBI) expression. Further, we also assessed the reproductive outcome of sex-sorted bovine semen in crossbred cows. Our data showed no significant difference in acrosomal integrity, oxidative stress, and expression of OPN and UBI between frozen-thawed unsorted crossbred and commercially procured sex-sorted bull semen. However, the DNA Fragmentation index (DFI) was significantly lower in the commercially procured sex-sorted frozen-thawed semen. Interestingly, our data suggested lower conception rates in synchronized cows artificially inseminated commercially procured sex-sorted semen compared to unsorted crossbred bull semen. Despite the lower conception rate, all the eight pregnant cows inseminated with commercially procured sorted bull semen delivered only female calves. Our study indicates the usefulness of commercial sex-sorted semen in field conditions to enhance the reproductive outcome in crossbred cows in India.
Assessment of chilli leaf curl disease risk in Kharif season for its establishment in southern states of India
Chilli leaf curl disease has emerged as a significant threat to chilli production in South India, particularly in major growing regions. To effectively manage this disease, understanding its spatial distribution and infection risk is crucial. A temperature-based infection model was developed for precise risk assessment, quantified as the monthly cumulative value of the daily infection index. Leveraging 39 years of historical weather data and 2 years of on-ground surveys (2021-2022), a geospatial analysis of infection risk was conducted. The study highlighted elevated risk during the kharif season, identifying Karnataka, Telangana, and parts of Kerala as prominent hotspots. Year-to-year variations underscored the vulnerability of chilli cultivation to climate change-induced temperature increases. This predictive approach, rooted in critical weather factors, holds implications for germplasm conservation, pesticide evaluation, and management strategy development. Overall, this research enhances our capacity to proactively mitigate the impacts of chilli leaf curl disease on agricultural productivity.
Efficacy of Napier grass for controlling sediment outflow under concentrated overland flow conditions
Soil erosion and sediment outflow processes are complex and dynamic in nature and depend on several factors such as climate, topography, soil, and management conditions. In bio-engineering projects, plant species are used to control surface erosion and improve the stability of slope. With hydrologic point of view, plants reduce soil erosion as they help in intercepting rainfall, reducing the kinetic energy of raindrop, enhancing infiltration, reducing the velocity of flowing water by providing the roughness over the land surface, transpiring soil water and adding organic matter to the soil and improve soil structure. An experiments were performed in a hydraulic tilting flume and controlled water circulation system. An experiments were carried out using three treatments 1. Control 2. Whole plant plot and 3. Roots plot at 1%, 2% and 3% slope with 6.6 l/s/m, 9.0 l/s/m, 10.7 l/s/m and 12.4 l/s/m runoff rate. Results summarized that Napier grass plot significantly reduced soil erosion as compared to the control plot. Further, it was also observed that the sediment outflow generation significantly decreased with the growth stage. Roots were more effective in controlling sediment rates compared to shoots.
