Exploring the Allelopathic impact of Wild Pomegranate leaf extracts in field crops establishment and early growth: study from Himalayas
The investigation was conducted in the Agroforestry laboratory of Department of Silviculture and Agroforestry, Dr. Y. S. Parmar university of Horticulture and Forestry Nauni Solan, H.P. in order to assess the allelopathic effect of wild pomegranate leaf extract on the germination and growth development of field crops (maize, mash, chickpea and wheat) along with five concentrations viz., 5%, 10%, 15%, 20% and control (100% distilled water) and four replication in CRD. Results revealed that all the crops were significantly affected by the leaf extract of wild pomegranate. The lowest seed germination (%) as well as growth parameters (radicle length and plumule length) of all the four crops were observed under the application of 20% concentration of leaf extract (T4), while the highest seed germination (%) and growth parameters were obtained under control i.e. 100% distilled water (T5). It was further observed that with increase in the concentration of leaf extract, all the parameters were decreased which shows the inverse relationship between concentration and germination/growth parameters. However, in overall comparison of all the four crops, the maximum germination (92.80 %) and plumule length (10.56 cm) was registered in mash, while, the maximum radicle length (9.14 cm) was recorded in wheat.
Agribusiness Incubators as Catalysts for Fisheries Enterprise Growth: A Performance Analysis
Many agricultural institutes have launched Agri-Business Incubators (ABIs) to foster venture creation in agriculture. This study evaluated the performance of prawn-based enterprises supported by the ABI at ICAR-Central Institute of Fisheries Technology, Cochin. The analysis highlighted the socio-economic characteristics of entrepreneurs graduating from the ABI and examined their product and technological profiles. Findings revealed that most enterprises were in their early stages and required technical and financial assistance for expansion. Technologies such as extrusion and retort packing, provided by the ABI, were widely adopted and underwent an economic feasibility assessment using the breakeven point (BEP) method. The BEP analysis estimated that enterprises became profitable at a production level of 400 units with a total cost of ₹20,000. The relatively low BEP confirmed the suitability of these technologies for small and micro enterprises. The study concluded that entrepreneurs who completed the incubation program achieved higher success rates, regardless of business size. These findings underscore the potential of ABIs as technology enablers in promoting entrepreneurship within the agricultural sector.
Cutaneous Plasma Cell Tumours(cPCTs) in dogs: Clinicopathological diagnosis of 36 cases in Chennai(2015-2024)
Plasma cell tumour(PCT) is a type of round cell tumour occurring in dogs, the other round cell tumours being mast cell tumour, transmissible venereal tumour, lymphoma and histiocytoma. In our study, a total of 36 cases of PCT were diagnosed from cutaneous masses in skin using cytological and histopathological methods. The highest incidence was recorded in Labrador and non-descript breeds, in male dogs, in dogs of age group 5-10 years and in trunk in breed, sex, age and in location wise analysis of tumour occurrence. Cytologic examination revealed abundant round neoplastic cells with distinct cell borders, eccentrically placed nuclei with perinuclear halo and prominent nucleoli. Histopathological examination revealed sheet of pleomorphic round neoplastic cells containing eccentric placed round to oval nuclei along with mitotic figures and multinucleated cells.
PATHOLOGICAL AND EPIDEMIOLOGICAL STUDY OF 524 CASES OF CANINE OCULAR DISORDERS IN CHENNAI
The research work was conducted to record the clinico-morphological attributes and prevalence of spontaneously occurring canine ocular disorders and to acquire comprehensive insights into the cytological, histopathological, cultural, immunohistochemical and hematobiochemical features of diverse ocular disorders in dogs. A total of 524 cases of various ophthalmic disorders were identified in dogs during the study period. In breed-wise occurrence, Shih Tzu breed represented the highest percentage of cases (113 cases, 21.5%) followed by non-descript (110 cases, 20.9%) and Labrador Retrievers (104 cases, 19.84%). In age wise occurrence, 47.5% of the cases were represented by dogs aged between 0-3 years followed by 3-6 years age group accounting for 25.62%. Males were overrepresented (274 cases, 52.79%) than females (245 cases, 47.2%). Bilateral involvement was recorded in 285 cases (54.3%). Unilateral involvement of right eye was recorded in 136 cases (25.9%) and left eye was recorded in 103 cases (19.65%). Intraocular pathological conditions had the highest incidence accounting for 68.12% followed by extraocular pathological conditions accounting for 27.85% and miscellaneous conditions accounting for 3.81%. In anatomic location within the eye, 42.2% cases were associated with the cornea, followed by lens which accounted for 13.1%, followed by third eyelid and eyelid which accounted for 10.8%.
Morphological characterization and Genetic divergence among the Niger (Guizotia abyssinica (L. f) Cass) germplasm
A field experiment was conducted with 114 germplasm to study the morphological characterization using self assumed description and nominal variables of morphological characters, which were used as an input for Nbclust hierarchical cluster analysis in which clustering was done using Ward’s minimum variance method and Euclidean’s method of genetic distance was derived. In this study, niger breeding lines were grouped into six clusters based on analysis of divergence at the genetic distance. They revealed considerable amount of genetic diversity. The largest cluster among all is cluster II. Cluster II has 34 germplasm, cluster I has 29, Cluster III has 24, cluster V contain 13, cluster IV has 9 and cluster VI has 5 germplasm. Whereas, morphological characterization observation were recorded on 12 traits viz., leaf color, leaf shape, leaf serration of margin, leaf angle of branching, stem hairiness, stem color, color of ray florets, plant branching habit, pollen color, seed color, seed shape and seed texture, etc.
