Residual effect of rate of Phosphorus and Organic mulch on performance of summer sweetcorn crop in Meghalaya
The integrative use of residue mulch and phosphorous benefits the crop growth and yield through increased availability of nutrients, in turn improve nutrient uptake leads to increase in growth and yield. The experiment was conducted to study the residual effect organic mulching and residual phosphorous of preceding crop on summer sweetcorn crop. The experiment was conducted in split-plot design with three residual organic mulch levels (un mulch (UM), rice straw mulch (RSM, maize stover mulch (MSM)) and four residual rates of P (0, 40, 80, 120 kg ha-1) on growth, nutrient uptake and yield of sweetcorn. At the time of harvest of sweet corn RSM and MSM has reported 13.68 and 9.62% higher plant height, 20.35 and 8.89% higher dry matter content, 34.79 and 24.21% higher CGR, 12.31 14.54% higher RGR, 11.74 and 6.99% higher LAI and 21.68 and 18.87% higher NAR has been reported respectively over UM. Among the rate of P, P120 has reported 13.74% higher plant height, 14.87% higher dry matter accumulation, 28.16% higher CGR, 8.30% higher RGR, 7.54% higher LAI, 15.22% higher NAR has been reported over P0 treatment. Overall mulching along with increased rate of P has improved growth, nutrient uptake and yield of sweetcorn crop.
A STUDY OF ENDOCRINOLOGICAL PROFILE OF ESTROGEN, PROGESTERONE AND PGFM (13, 14-dihydro-15-keto-PGF2alpha) DURING ‘DOKA’ IN MURRAH BUFFALOES ( Bubalus bubalis)
Silent estrus is one of the most common problems in the buffalo farming industry. Quick and accurate estrus detection can reduce economic losses in the dairy sector. ‘Doka’ also referred as Temporary Engorgement of Teat (TET) is a behavioural pre-estrus sign which is characteristic of buffaloes. The present study was conducted with the objective to examine various endocrinological changes during ‘Doka’. The present study was conducted with the objective to examine endocrinological changes during ‘Doka’ in Murrah buffaloes. Non-pregnant lactating Murrah buffaloes (n=24) across parities maintained at ICAR-CIRB, Hisar in an organized dairy farm were divided into four groups with six animals in each group viz. Group I: Cyclic ‘Doka’, Group II: Cyclic without ‘Doka’. Group III: Acyclic ‘Doka’. Group IV: Acyclic without ‘Doka’. The present study confirmed that the cyclic ‘Doka’ and cyclic without ‘Doka’ animals had plasma progesterone levels of (>2ng/ml) while those in acyclic animals it was <1 ng/ml. The levels of plasma estrogen in ‘Doka’, cyclic, or non-cyclic animals across different groups were non-significant. However, ‘Doka’ showing animals have significantly high PGFM (13,14-dihydro-15-keto-PGF2alpha) concentrations (p<0.05) in comparison to cyclic without ‘Doka’ animals (4.32±0.29 vs 3.47 ±0.21ng/ml).
Udder and Teat morphology during ‘Doka’ in cyclic and acyclic Murrah buffaloes (Bubalus bubalis)
‘Doka’ is a temporary teat engorgement phenomenon lasting for 3 to 5 days before the onset of the estrus period in cyclic and acyclic Murrah heifers. It is commonly observed by villagers in Haryana as an indicator of the initiation of cyclic reproductive activity or estrus in buffaloes. The present study was conducted to observe the morphological changes in the teat and udder during and after ‘Doka’ in Murrah buffaloes. Udder morphology was studied in thirty-five animals, which were categorized into two groups: Group I - cyclic ‘Doka’ (n=14) and Group II - cyclic without ‘Doka’ (n=21). Additionally, both udder and teat measurements were studied in forty-six animals, further divided into four categories: Group I (n=19) - cyclic ‘Doka’, Group II (n=14) - cyclic without ‘Doka’, Group III (n=6) - acyclic ‘Doka’, and Group IV (n=7) - acyclic without ‘Doka’. Cyclic ‘Doka’ animals exhibited a bowl-shaped udder, cylindrical teats, and fused quarters. During ‘Doka’, cyclic ‘Doka’ (7.41±0.23 inches) and acyclic ‘Doka’ (7.30±0.79 inches) animals showed significantly greater udder depth compared to acyclic animals without ‘Doka’ (7.41±0.23 inches). The teat length of fore and rear teats in cyclic ‘Doka’ animals was non-significantly (p<0.05) higher during the ‘Doka’ stage compared to the post-‘Doka’ stage. Rear teat diameter in acyclic ‘Doka’ animals (37.73±3.93 mm) was significantly (p<0.05) larger than that in acyclic animals without ‘Doka’ (24.74±2.16 mm).Therefore, it can be concluded that udder and teat morphological changes during ‘Doka’ can serve as a useful tool for estrus detection in Murrah buffaloes.
The Role of Responsible Communication in Promoting Agricultural Sustainable Development Through Digital Marketing in Algeria
In the digital era, responsible communication plays a crucial role in shaping sustainable marketing strategies. This study explores the impact of responsible communication on promoting sustainable development through digital marketing in Algeria. By integrating theoretical insights from corporate social responsibility (CSR), sustainability, and digital marketing, the research examines how consumer trust and corporate reputation mediate this relationship, while government regulations and social norms act as moderating factors. Using Structural Equation Modeling (SEM) in Lavaan, data was collected from Algerian businesses engaged in digital marketing and analyzed to assess the relationships between the variables. The results highlight the significance of ethical communication in fostering consumer trust, strengthening sustainable brand engagement, and enhancing overall sustainability outcomes. The findings offer valuable insights for policymakers, marketing professionals, and business leaders on leveraging responsible communication strategies for sustainable development in Algeria’s digital economy.
Application of digital twin technology in the design of production processes, production and operation of complex technical systems in special operating conditions
The modern industry is digitalizing at an ultra-fast pace. An increasing number of industrial enterprise processes are controlled using digital technologies. Moreover, an increasing number of production and technological processes are implemented in a highly automated or robotic way, and for such processes any control other than digital is impossible in general. The recent trend in the development of information technologies for production management is the creation of digital twins. This article analyzes the concepts of digitalization and digital twin. An idea is given of the approach to the implementation of digital twin technology in the production process and operation of complex technical systems. Subclasses of innovative tools used in this technology are structured. The directions of development of the system of operation of its subsystems in special conditions are presented. Particular attention is paid to methods for diagnostics and monitoring the state of objects with the ability to predict their changes in real time, as well as the use of additive technologies in the process of restoring the health of complex technical systems.
