Item Analysis of Biochemical and Phytochemical Parameters of Chromolaena odorata (L.) R.M. King & H. Rob. and Adhatoda vasica Nees(2016-04) Bindhu, V; Gayathri, VItem Assessment of Biochemical Parameters in Paddy Seedlings(2015) Gayathri, VAn assessment was done to investigate the effect of farmyard manure, DAP, neem cake and leaf extract on biochemical (viz., chlorophyll, protein and carbohydrate) parameters of paddy seedlings. The biochemical parameters were measured on 30th and 45th day. The values indicated that the chlorophyll 'a', chlorophyll `1,' and total chlorophyll contents were higher in T4 on 30th day and 45th day. Similarly, the protein content was higher on 30th and 45th day in 0.5 ml extract of T4 plants. In 1 ml of sample, on 30th day, the protein content was higher in T1 and on 45th day, it was higher in T4. The carbohydrate content of plants also increased in plants supplied with leaf extracts.Item Assessment of Biochemical Parameters in Paddy Seedlings(2015) Gayathri, VAn assessment was done to investigate the effect of farmyard manure, DAP, neem cake and leaf extract on biochemical (viz., chlorophyll, protein and carbohydrate) parameters of paddy seedlings. The biochemical parameters were measured on 30"* and 45'*' day. The values indicated that the chlorophyll 'a \ chlorophyll 'b ’ and total chlorophyll contents were higher in T4 on 30**' day and dS"* day. Similarly, the protein content was higher on 30'*' and dS'** day in 0.5 ml extract of T4 plants. In 1 ml of sample, on 30“* day, the protein content was higher in T| and on ds"* day, it was higher in T4.The carbohydrate content of plants also increased in plants supplied with leaf extracts.Item Automatic Questions Generation Using Natural Language Processing(2022-05) Gayathri, V; Srividhya, VItem Effect of different fertilizers on growth and biochemical parameters of Oryza sativa L. var. IR 20(2015-03) Anusuya, S; Gayathri, VItem Effect of Inorganic Fertilizers and Herbal Leaf Extracts on Biochemical Parameters of Black Gram(2013) Gayathri, VGreen manures play a key role in providing subsequent crops with nutrients, maintaining soil quality, and helping to control weeds and pests . The most important features of a green manure are large dry matter production and high ability to fix nitrogen. Green manure can be used directly or after composting as a nutrient input that will, after decomposition, be taken up by crops to produce biomass and grain. The effectiveness of green manuring as a soil fertility management technology depends on the stage of crop during incorporation, placement (incorporated or surface placement), nutrient content and carbon to nitrogen ratio of material which influences decomposability and mineralization. In the present study, the efficacy of certain organic and inorganic fertilizers on the biochemical parameters such as chlorophyll, protein and carbohydrates were analyzed. It was found that the Di ammonium phosphate and leaf extract either singly or in combination showed higher biochemical activity.Item Effect of Inorganic Fertilizers and Herbal Leaf Extracts on Biochemical Parameters of Black Gram(2013) Gayathri, V; Prabha Sherlina, F; Anju SinghGreen manures play a key role in providing subsequent crops with nutrients, maintaining soil quality, and helping to control weeds and pests .

Moench(2021-05) Kanimolee, M; Gayathri, VItem Efficacy of Azospirullum, Phosphobacteria and Spent Mushroom Compost on the Growth parameters of Solanum lycopersicum L.(2021-05) Dharshini, K; Gayathri, VItem Efficacy of different organic manures on the growth of Solanum lycopersicum L.(2022-05) Thulaja, R S; Gayathri, VItem Efficacy of Vermicompost and Vermiwash on Growth parameters of Solanum lycopersicum L.(2022-05) Shanthni, J; Gayathri, VItem Evaluation of Biochemical and Phytochemical Parameters of Solanum nigrum L. and Leucas aspera (willd.) Linn.(2016-04) Karthika, A; Gayathri, VItem Fluorescence Analysis of Two Medicinal Plants - Psidium Guajava L and Citrus a Urantium(2015) Gayathri, VThe plants used for the present study viz., Psidinm guajava L and Citrus aurantium belong to the family Myrtaceae and Rutaceae respectively. Guava is native to tropical America. The young leaves are used as tonic in digestive disorders. Bitter orange is native of South Eastern Asia; grow in Tamil Nadu, Karnataka, Maharashtra, Punjab and Uttar Pradesh. It is a rich source of provitamin A. The present investigation on the fluorescent characters of the leaf powder showed varied colours like green, pale green, dark green, brown and yellow under different chemical treatments in both the medicinal plants used for the study.Item Fluorescence Analysis of Two Medicinal Plants — Psidium Guajava L and Citrus Aurantium(2014) Gayathri, V; Kiruba, DThe plants used for the present study viz., Psidium guajava L and Citrus aurantium belong to the family Myrtaceae and Rutaceae respectively.

Aerenchyma is a constitutive feature in rice, and has thus served as one of the two model plants (the other being corn) for studies on the formation of irregular lysigenic aerenchyma among the monocot, formed as a result of the breaking down of cortical cells. An increase in the proportion of aerenchyma is dependent on the rice cultivar, and the developmental stage of the plant. In the present study, the significant result is with reference to the increased diameter of vessels in all organs of plants associated with cyanobacteria.Item Histological Studies on Rice Plant in Association With Cyanobacteria, Oscillatoria Foreaui Fremy(2013) Gayathri, VThe abundance of cyanobacteria in paddy fields and the consequent sustenance of the nitrogen status of rice fields is an important aspect of economic relevance.
