ThesisItem Open Access Effect of organic manures and inorganic fertilizers on growth, flowering and yield of gladiolus (Gladiolus grandiflorus L.)(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2016-06) Panwar, Anil; Bhuj, B.D.The present investigation was carried out at Model Floriculture Centre, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, District- Udham Singh Nagar, Uttarakhand, during October 2015 to April 2016. Investigation was laid out in randomized block design (RBD) with 9 treatment and three replications to study the effect of organic manures and inorganic fertilizers on growth, flowering and yield of gladiolus (Gladiolus grandiflorus L.)”. Observations were recorded on various parameters of vegetative growth, flowering and corms attributes. At 60 days the maximum plant height (76.87 cm) was obtained in T2 (Farmyard Manure + 75% Recommended Dose of Fertilizers) while the maximum leaves number/plant (13) was exhibited by T5 (50% Farmyard Manure + 50% Neem Cake). Regarding flowering characters the treatments T6 (75% Farmyard Manure + 25% Poultry Manure) responded best result especially in commercial traits like spike length (100.83 cm), number of floret/spike (15.58) and rachis length (56.17 cm). In respect of corms characters there were a positive response by the application of various organic manures. The maximum number of corm/plant (1.9) was recorded in T8 (75% Vermicompost + 25% Poultry Manure) while maximum weight of single corm (146 g) was found in T5 (50% Farmyard Manure + 50% Neem Cake). The equal proportion of all organic manures [T9 (25% Farmyard Manure + 25% vermi compost + 25% Neem Cake + 25% Poultry Manure)] recorded maximum number of cormels/plant. On the basis of present findings it may be concluded that there was a positive effect of the application of organic manures on vegetative growth, flowering, and corms characters as well as to sustain the soil fertility by the residual presence of nitrogen, phosphorus, potassium, organic carbon and maintenance of normal pH and electrical conductivity of the soil.ThesisItem Open Access In-silico identification of phytochemicals as potential agents to inhibit the growth of pests(CCSHAU, Hisar, 2023-05) Gahalyan, Dushyant; Panwar, AnilCompounds known as phytochemicals have a specific biological effect against pests. Insect molting and metamorphosis are controlled by ecdysteroids and the juvenile hormone. The natural hormone responsible for molting in the majority of insects, 20-hydroxyecdysone (20E), binds to and activates the ecdysone receptor (EcR), a heterodimer made up of two nuclear receptor proteins. EcR is an attractive target for safer and more targeted pesticides since compounds that act on it exclusively harm insects and other arthropods. Farmers mainly rely on quick pest management strategies to defend crops from pest attacks, primarily synthetic insecticides. Overuse and abuse of synthetic pesticides can have harmful effects on people, the environment, and non-target animals, which reduces biodiversity. Some toxic pesticides that could be extremely detrimental to mammals or the environment are aldicarb, malathion, parathion, etc. Many crop pests and human ailments have been successfully controlled by plants that produce bioactive compounds. High-throughput screening technologies have been created to effectively look for novel chemicals that interfere with the insect endocrine system. These methods will support the creation of ecdysone agonists that are particular for insect orders like Lepidoptera, Diptera, or Coleoptera's EcRs. The two receptors that were complexed with ligands were employed in this work to estimate binding affinity and predict binding mode. The potential orientation of a ligand with respect to a protein target can be determined extremely effectively using molecular docking. In this study, 93 phytochemical agents are docked against the main receptor of Heliothis virescens, and Bemisia tabaci. Five-five candidates are selected according to their high binding affinity for each insect, i.e. Helitohis Virescens (1R1K) and Bemisia tabaci (1Z5X). It is observed that for 1Z5X (Uscharin, Meliantriol, Campesterol, Daturaolone, and Epoxyazadiradione, which had binding affinities of -13.61, -13.28, -13.26, -12.29 and -12.24, respectively) were selected and for 1R1K (Campesterol, Azadirone, Uzarigenin, Meliantriol, and Pyrethrin-2 which had binding affinities of -13.12, -11.48, -9.94, -9.84 and -9.37, respectively) were selected. According to molecular dynamics simulation (20ns) investigations of the selected compounds, the top five docked 1R1K and 1Z5X compounds appear to have strong stability, flexibility, and binding affinity for ecdysone receptors.
