Multifarious plant growth-promoting Bacillus strains recovered from rhizospheric soils of the Indo Gangetic plains (IGPs) were identified as Bacillus licheniformis MNNITSR2 and Bacillus velezensis MNNITSR18 based on their biochemical characteristics and 16S rDNA gene analysis. Both strains exhibited the ability to produce IAA, siderophores, ammonia, lytic enzymes, HCN production, and phosphate solubilization capability and strongly inhibited the growth of phytopathogens such as Rhizoctonia solani and Fusariun oxysporum in vitro. In addition, these strains are also able to grow at a high temperature of 50 °C and tolerate up to 10–15% NaCl and 25% PEG 6000. The results of the pot experiment showed that individual seed inoculation and the coinoculation of multifarious plant growth promoting (PGP) Bacillus strains (SR2 and SR18) in rice fields significantly enhanced plant height, root length volume, tiller numbers, dry weight, and yield compared to the untreated control. This indicates that these strains are potential candidates for use as PGP inoculants/biofertilizers to increase rice productivity under field conditions for IGPs in Uttar Pradesh, India. © 2023 by the authors.
Upscaling residential solar rooftop in Uttar Pradesh: review of policy, practices and stakeholders perspective, identification of challenges and solutions
(Elsevier Ltd, 2025) Ashish Tiwari; R. K. Mall; Maheswar Rupakheti
This research paper examines the barriers and solutions related to the adoption of residential rooftop solar (R-RTS) in Uttar Pradesh. Despite government policy interventions, R-RTS uptake remains limited compared to the state's energy consumption-based potential. The study systematically analyses key adoption issues, stakeholder perspectives, policy landscape and identifies critical issues such as policy gaps, implementation challenges, and stakeholder collaboration deficits through policy review, stakeholder analysis, and adoption drivers. Methodologically, the study employs a mixed qualitative approach, including document analysis, stakeholder consultations, and field insights. The study proposes following actionable solutions: i) Policy interventions for subsidies beyond 3 kW. ii) Relaxation on system capacity limits. iii) Enhanced compensation for excess electricity injected into the grid. iv) Strategies to improve vendor participation. v) Addressing DISCOM inefficiencies regarding net meter availability and verification delays. vi) Speedier subsidy transfers. vii) Targeted awareness campaigns.The research highlights the importance of post-installation service ecosystems, advocating for skilled manpower development and product standardization to improve local service access. The intended policy outcome is to create a more enabling environment for residential R-RTS adoption, supporting climate goals and decentralized renewable energy expansion. This paper provides a structured roadmap for policymakers, vendors, consumers, and implementors to scale rooftop solar adoption in Uttar Pradesh. © 2025 Elsevier B.V.
