Identification of Constraints Faced by Farmers in Adoption of Fish Farming in Haryana
Fish culture has become a popular enterprise in the Haryana state but the production level has not met the demand for a very long period. So, it is important to identify the barriers which are working behind the growth and development of fish farmers in the Haryana state. The current investigation took place in eight districts of Haryana, India comprising two zones i.e., ARTI-I and ARTI-II. The primary objective was to understand the challenges confronted by farmers in adoption of fish farming. The findings presented in this paper stem from a field survey conducted during the 2023-24 period, involving 240 respondents. These participants were interviewed using a well-structured and pre-tested interview schedule. The analysis of the collected data employed the Statistical Package for Social Sciences (SPSS) tool. Results revealed that The results indicate that a majority of respondents identified financial constraints (WMS 2.59) as highly serious, while constraints related to society were considered comparatively less serious (WMS 2.27). Further analysis of data revealed that only 20 items out of 39 items had eigenvalue more than one and 65.49 per cent variation in result was caused by those 20 items only. The study's conclusion highlights that most respondents perceive these constraints as significant, underscoring the urgent need to motivate and encourage farmers to adopt better management practices.
Performance of Wheat (Triticum aestivum L.) under Conservation Tillage and Integrated Weed Management in Middle Indo-Gangetic Plains of India.
A field experiment was conducted during two consecutive rabi seasons (2022–23 and 2023–24) at Bihar Agricultural University (BAU), Sabour, Bhagalpur, India, to evaluate the effects of different tillage systems and weed management practices on weed dynamics, growth, and productivity of wheat. The experiment was laid out in a split-plot design, three replications with three tillage practices as main plot treatments and six weed management options as sub-plot treatments. Results revealed that zero tillage combined with retention of paddy crop residues significantly reduced weed infestation and improved crop growth and grain yield compared to other tillage practices. Among the herbicidal treatments, the application of sulfosulfuron + metsulfuron methyl (30 + 2 g a.i. ha⁻¹) was the most effective in minimizing weed density and biomass, followed by mesosulfuron methyl + iodosulfuron methyl sodium (12 + 2.4 g a.i. ha⁻¹). Based on the findings, the study recommends the adoption of zero tillage with residue retention along with sulfosulfuron + metsulfuron methyl for efficient and sustainable weed management and enhanced wheat productivity in the Middle Indo-Gangetic Plains of India.
H₂/H∞-Based LPV Gain-Scheduled Control for Enhancing Lateral Stability of Distributed-Drive Electric Vehicles
The Direct Yaw Moment Control (DYC) system plays a vital role in steady-state handling and serves as a fundamental component for trajectory tracking and active safety mechanisms during high-speed driving. In distributed-drive electric vehicles, DYC leverages the full potential of a four in-wheel motor setup by independently controlling the driving forces across all wheels. This allows for the transition from passive intervention under extreme conditions—when the vehicle nears instability—into proactive control, enhancing safety. However, in real-world scenarios, discrepancies between model parameters and actual vehicle behaviour, along with external disturbances and parameter variations, pose significant challenges to the controller’s adaptive performance. To improve lateral stability control in such vehicles, this paper introduces a robust adaptive controller based on H₂/H∞ theory with prescribed performance for direct yaw moment regulation. This study aims to minimize the impact of external disturbances and input noise on the vehicle's dynamic control system. By introducing an online parameter adjustment mechanism and dynamically correcting key vehicle parameters, the feedback gain matrix is updated in real time using the LPV gain scheduling method, with the longitudinal vehicle speed treated as a time-varying parameter. The algorithm ensures the controller's adaptability and robustness, effectively responding to environmental changes and resisting noise. Simulation experiments show that the algorithm performs well under various operating conditions, significantly improving controller performance and reducing system uncertainties, with promising application prospects.
Effect of foliar spray of potassium nitrate under different tillage methods on growth and productivity of Wheat (Triticum aestivum L.)
A field experiment was conducted at the Research Farm of Bihar Agricultural University, Sabour, Bhagalpur (Bihar) in Rabi season of 2024-25 to assess the “performance of conservation tillage and foliar nutrition of potassium nitrate on growth, yield attributes and productivity wheat. The experiments was laid out in split-plot design and replicated thrice with three levels of tillage practices viz Conventional tillage (M1), Zero tillage (M2) and Raised bed tillage (M3) and four levels foliar nutrition of potassium nitrate viz, control (F1), 1% KNO3 foliar spray at boot leaf stage (F2), 1% KNO3 foliar spray at post anthesis stage (F3) and 1% KNO3 foliar spray both at boot leaf and post anthesis stage(F4). Zero tillage (M2) recorded significantly higher dry matter accumulation, tiller number m⁻², and leaf area index (LAI) compared to the raised bed tillage (M3), and was statistically at par with conventional tillage (M1). Raised bed tillage (M3) produced the highest grains ear⁻¹ (44.21), ear length (11.60 cm) and test weight (41.76 g). Ear head density m⁻² was highest under zero tillage (M2). Zero tillage (M2) produced the highest grain (4528.9 kg ha⁻¹) and straw yield (6678.7 kg ha⁻¹). Among foliar nutrition treatments, Foliar spray of 1% KNO₃ at both booting and post-anthesis stages (F4) significantly enhanced dry matter accumulation and LAI, although plant height, tillers m⁻² and yield attributes (ear heads m⁻², grains ear⁻¹, ear length, and test weight), could not reached to the level of significance. Foliar application of 1% KNO₃ at boot leaf stage and post anthesis stage (F4) recorded significantly increased grain (4501.6 kg ha⁻¹) and straw yield (6610 kg ha). Interaction effect was also found significant under zero tillage (M2) with 1% KNO3 foliar spray at boot leaf and post anthesis stage (F4) in case of grain yield (4658.23 kg ha -1) and straw yield (6752.63 kg ha -1). Among different treatments zero tillage (M2) with 1% KNO3 potassium nitrate spray at boot leaf and post anthesis stage (F4) fetched higher yield and sustaining soil health.
PHAs-rich SCP: a Promising Nutraceutical Feed For Future
The global demand for sustainable and health-enhancing feed additives has catalysed interest in single-cell protein (SCP) enriched with polyhydroxyalkanoates (PHAs), which holds potential as an effective replacement to antibiotics. PHAs-rich SCP offers a unique convergence of high-quality protein and biodegradable biopolymers with nutraceutical properties, presenting a promising alternative to conventional feed sources. This review explores the potential of PHAs-rich SCP as a novel nutraceutical feed ingredient, highlighting its microbial sources, production strategies, compositional advantages, dual functionality as both protein source and bioactive compound and current challenges & future prospect. Emphasis is placed on its nutraceutical roles including immunomodulatory, antioxidant, and gut health-promoting effects, alongside environmental and economic benefits. Furthermore, this article aims to provide a comprehensive insight into the multifaceted value of PHAs-rich SCP, advocating its role in promoting sustainable and health-oriented animal nutrition.
