    Effect of Inorganic Fertilizers and Herbal Leaf Extracts on Biochemical Parameters of Black Gram
    (2013) Gayathri, V; Prabha Sherlina, F; Anju Singh
    Green 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 ccntent 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.

    Preliminary Phytochemical Analysis of Black Gram, Vigna Mungo L
    (2013) Prabha Sherlina, F
    Black gram ( Vigna mungo L.) is an important pulse crop occupying unique position in Indian agriculture. The study of phytochemicals, secondary metabolic substances in plants are known to provide protection against insect attacks and plant diseases. The current investigation is an attempt to study the preliminary phytochemicals that are present in black gram using different solvent extracts. An experiment was conducted to study the influence of chemical fertilizers (DAP and superphosphate) and leaf extracts (Ocimum basilicum and Lantana camara L.) on the presence of secondary metabolites. The results showed the presence of fiavonoids, terpenoids, quinone, sterols, oil and fat by various tests.
