Indian mustard (Brassica juncea L.) is a preeminent winter oilseed crop crucial to the global edible oil economy, historically reliant on intensive chemical fertilization to maximize seed and oil yields. However, prolonged dependency on synthetic NPK (Nitrogen, Phosphorus, and Potassium) fertilizers has precipitated severe secondary consequences, including the depletion of soil organic carbon (SOC), microflora collapse, and subsequent yield stagnation. This paper evaluates the agronomic, physiological, and economic impacts of integrating diverse organic preparations-ranging from bulky organic manures (Farm Yard Manure, Vermicompost) to microbial biofertilizers (Azotobacter, Phosphate Solubilizing Bacteria) and liquid bio-stimulants (Jeevamrit, Vermiwash, Panchagavya)-into mustard cultivation. A review of randomized block design field experiments demonstrates that an exclusively chemical approach degrades long-term soil health, while a purely organic approach often sustains a short-term yield penalty due to the slow mineralization of essential nutrients. Consequently, the Integrated Nutrient Management (INM) framework emerges as the most viable agronomic strategy. Substituting 25% to 50% of the Recommended Dose of Fertilizers (RDF) with high-quality organic sources, augmented with biofertilizer seed priming or soil inoculation, significantly optimizes vegetative growth parameters such as plant height and primary/secondary branching. Furthermore, liquid organic foliar applications during critical phenological stages (branching and flowering) delay leaf senescence and enhance the grain-filling period. This synergistic approach not only maximizes final seed yield and oil content largely by replenishing vital secondary nutrients like Sulphur but also yields the highest Benefit: Cost (B:C) ratio. Ultimately, the strategic application of organic preparations is not merely an alternative farming method, but a scientifically imperative intervention to restore rhizosphere health, ensure climate resilience, and sustain the long-term productivity of mustard cultivation.

Koi Herpesvirus (KHV) or Cyprinid herpesvirus-3 (CyHV-3) is considered among the most damaging viral diseases of common and koi carp aquaculture across the world. Koi herpes virus causes high mortalities, economic losses, and trade restrictions in aquaculture industry. One of the major problems related to KHV is its capability to cause latent infection in surviving fishes. In latent infection, the virus exists in hiding within the host organisms without showing any clinical signs; mainly within leukocytes and nervous tissues. Latently infected fishes serve as silent carrier of the virus that can be reactivated under certain stress conditions such as temperature change, transportation, crowding, and poor water conditions. Reactivation causes shedding of virus from latently infected fish and further spread of virus among clinically healthy fish populations. Research has shown that KHV DNA can be detected in blood leukocytes and many other organs even in healthy carp. Temperature changes have been reported as one of the most important factors that induce viral shedding from latently infected fishes. The detection of latent infection is very difficult due to presence of extremely low numbers of viral DNA during latency stage. PCR and Realtime PCR have been used successfully to detect latent KHV infection. It is necessary to have good surveillance, biosecurity measures, stress reduction, and periodic screening in order to avoid silent transmission of the virus. It is vital to understand the process of latent infection and reactivation for sustainable carp farming.

Mithun (Bos frontalis), an indigenous bovine species of Northeast India, holds immense socio-economic and cultural importance among tribal communities. In recent years, scientific reproductive management practices such as Artificial Insemination (AI) have gained attention for improving the reproductive efficiency and genetic potential of Mithun populations. However, successful implementation of AI in Mithun is often constrained by the occurrence of silent estrus, where behavioural signs of heat are weak and difficult to identify. This article highlights the major techniques used for estrus detection and artificial insemination in Mithun. Important estrus indicators including mounting behaviour, standing heat, vulval swelling, mucous discharge and uterine tone are discussed in detail. The article also describes various estrus detection methods such as visual observation, use of teaser bulls, fern pattern examination of vaginal mucus and rectal palpation. In addition, the principles, advantages, ideal timing and procedure of artificial insemination in Mithun are elaborated. This review emphasizes the importance of proper estrus detection and AI practices for the genetic improvement and conservation of Mithun in Northeast India.
