The document discusses a study on the effects of different organic manures on the growth of selected medicinal plants in Tamil Nadu. It outlines the importance of medicinal plants for healthcare, the growing demand threatening their sustainability, and the need for domestication and cultivation using organic fertilizers. The methodology includes experimentation with various treatments and observations of growth parameters for multiple species, supported by a review of relevant literature.

Studies on the Effects of different
Organic Manures on the Growth
parameters of selected medicinal
plants of TamilNadu

2. Introduction
 Medicinal plants have therefore been considered a healthy source of life for the people who are able to harvest them
from the wild to meet their primary health care needs.
 The result of the increased demand in both local and international markets as well as bio-prospecting activities
searching for sources of new drugs is a source of great concern.
 Karki (2002) estimated that 95% of Medicinal and Aromatic Plants (MAPS) in developing countries are harvested
and collected in wild.
 Ahenkan & Boon (2008) observed that the very foundation upon which the medicinal plant species and the
traditional health care system survive is threatened by deforestation, population growth, urbanization.
 The difficulties experienced in the collection of plants from forest and the problems encountered there in together
with heavy demand of medicinal plants necessitate domestication of medicinal plants.

3. Objectives
 To collect various medicinal plants and seeds from wild and cultivated domestically.
 To study the growth of selected medicinal plants by the application of various organic manure.
 To evaluate the suitable organic manure which gives ideal result when compared with one another.
 To determine the various abiotic factors such as rainfall, sunlight which affects plant growth.
Significance
o There is a rising focus on the significance of medicinal and aromatic plants in health systems, solving the health care
problems of the world. Present research in drug innovation from medicinal plants involves a versatile approach
combining botanical, phytochemical, biological and molecular techniques (Sastry et al., 2015).
o Medicinal and aromatic plants; are known to be used by 80 % of global population for their medicinal therapeutic
effects as estimated by WHO (2008).
o Traditionally, medicinal plants are collected from areas where they are wildly and naturally grown. The use of organic
fertilizers with species of medicinal and aromatic plants under organic agriculture helps in improvement of yield and
quality.

4. Review of literature
 Natarajan (2002) - Panchagavya was tested for different crops such as turmeric, paddy, onion, gingelly, sugarcane,
banana, vegetables and curry leaf and it was found that it enhanced the growth, vigour of crops, resistance to pest and
diseases and improvement of keeping quality of vegetables and fruits.
 Vennila et al., (2008) - revealed that application of 100% recommended dose of fertilizer along with Panchagavya
spray (2%) significantly increased the okra plant height (131.7 cm) and dry matter production (5.90 g plant-1).
 Saikia & Upadhyaya, (2011) - analysed with the roots of Asparagus racemosus grown under organic manures -
Cow dung, compost and vermicompost without using mineral or chemical fertilizer showed that the total phenol and
total flavonoid content was highest in the plants from vermicompost treated soil. The antioxidant activity was highest
in the plants from cowdung treated soil.
 Sailaja et.al., (2014) - conducted experiment to evaluate the potential of utilizing panchagavya as biofertilizer, on
the leafy vegetable Spinacia oleracea. The biomass, shoot length and root length were recorded in control and
panchagavya treated plants.

5.  Zaman et.al., (2017) - observed the effects of cow dung on growth, yield of stevia along with post-harvest fertility
status of soil. Growth and yield attributes increased significantly with the advancement of growth period (60 DAP)
and increased rate of CD up to 10 t ha–1. An overall performance of non-calcareous soil was better than acid soil.
 Gill et.al., (2018) - Investigated the impact of different fertilizers i.e, cow dung, vermicompost and urea on growth
parameters of tomato (Lycopersicum esculantum) in 16 pots. Pots in, first, second and third rows were treated with
cow dung, urea and vermicompost respectively and fourth rows was kept as control, per pot one plant was grown
and five different growth and yield parameters.
 Uthirapandi et.al., (2018) - Panchagavya were given to the tested plant in form of foliar spray. Foliar application of
2%, 4%, 6% and 8% (T1, T2, T3 and T4) enhanced the overall growth and physiology of Ocimum Sanctum. There
was an appreciable increase in growth and biochemical parameters in the treated plants that received 8% (T4) when
compared to other treatment and control.
 New et.al., (2019) - Conducted the two - factor factorial experiment comprised of 3 levels of cow dung (0,10 and 15
t ha –1) and 4 levels of N fertilizer (0,80,120 and 160 N ha –1) were set as factors A and B, respectively using
randomized complete block design with four replications of cabbage (Brassica oleracea var. capitata L.). The results
showed that maximum marketable yield was recorded in cow dung (15 t ha –1) producing of maximum plant
height, and the shortest period for head initiation and for head maturity.

6. Methodology
 The experiment was carried out with medicinal plant saplings and few number of seeds. It was accomplished in plant
growbags with organic manures.
 One pot is without any treatment (Control), second pot is mixed with soil in equal ratio of Coco peat + cow dung as
(T1) and the last one Panchagavya (T2).
 Measurement of growth of those medicinal plants were studied at 10 days interval. Totally 10 different medicinal
plants were taken include the seeds.
 Herbaceous plant saplings like Indian pennywort, insulin plant and ballon vine were taken. Shrubs like long pepper,
willow - leaf justicia, sweet leaf plant and sugar destroyer were taken.
 Seeds of neem, papaya and moringa were taken. For seeds the manure were mixed with the soil and for the plant
saplings panchagavya was sprayed.
 The data of each plant growth parameters were analysed statistically.
