ThesisItem Open Access GEO-REFERENCING AND ASSESSMENT OF MORPHO-BIOCHEMICAL DIVERSITY OF KALMEGH UNDER IN VIVO CONDITIONS IN JHARKHAND(Birsa Agricultural University, Ranchi, 2023) MADHURA M S; Jai KumarIn light of the global utilization of wild medicinal plants for pharmaceutical purposes, it has become imperative to search for medicinal plants that yield high biochemical contents. The secondary metabolites produced in Kalmegh are the result of environmental and edaphic conditions in which it grows and it becomes essential to identify the reasons that contribute towards maximum biochemical production in Kalmegh. The agro climatic sub-zone V of Jharkhand is considered as relatively superior for higher yield and biochemical contents production of Kalmegh, hence the present research was undertaken to corroborate the hypothesis and assist the region in securing a Geographical Indication (GI) tag with the following objectives (i) To assess morpho-biochemical diversity of Kalmegh in all three agroclimatic zones of Jharkhand under in-vivo conditions. (ii) To conduct geo-referencing of morpho-biochemical traits of Kalmegh in all three agroclimatic zones of Jharkhand under in-vivo conditions. (iii) To analyze the traits association studies with local climatic and edaphic conditions to screen out striking factors contributing towards the uniqueness of Kalmegh. The experiment comprised a total of 50 treatments which consisted of three replications and 30 plant samples in each treatment. The number of treatments from agro climatic sub-zone V, IV and VI were forty, five and five respectively. For each location, the coordinates and altitude were recorded, plant growth and yield parameters were measured and soil samples were collected for further analysis. HPLC analysis of plant samples was carried out at CIMAP, Lucknow. Meteorological data was collected for the plant growth period until harvest. Geo-referencing and grid mapping of diversity was carried out using DIVA-GIS (Version 7.5). Statistical analysis was carried out using OPSTAT and INDOSTAT. Highly significant difference was observed in mean leaf length, mean leaf width, mean length of internodes, mean number of internodes, andrographolide percentage and neo-andrographolide percentage in Kalmegh germplasm collected from agro climatic sub-zone IV & VI while, significant difference was observed in mean plant height, mean stem diameter, mean number of primary branches, mean fresh weight/plant, mean dry weight/plant, mean leaf weight/plant, mean stem weight/plant, and mean leaf stem ratio between the germplasm collected from agro climatic sub-zone IV and VI. Highly significant difference was observed in mean number of primary branches, mean leaf length, mean leaf width and mean length of internodes in Kalmegh germplasm collected from agro climatic sub-zone V & VI while, significant difference was observed in mean number of internodes and neo-andrographolide content of Kalmegh between the germplasm collected from agro climatic sub-zone V and VI. Highly significant difference was observed in mean leaf lamina width between the germplasm collected at agro climatic sub-zone IV & V. Maximum plant height was recorded at T2-Kujram (71.14 cm) followed by T4-Kujram (66.36 cm), while maximum stem diameter was recorded at T2-Kujram (5.35 mm) followed by T1-Tarub (4.79 mm). Maximum number of primary branches/plant was recorded at T5-Dangiadagh (4.57) followed by T4-Kujram (4.40) and maximum leaf lamina length was recorded at T4-Kujram (4.72 cm) followed by T5-Dangiadagh (4.56 cm). Maximum leaf lamina width was recorded at T4- Kujram (2.04 cm) followed by T10-Remta (2.00 cm) and maximum length of internodes was recorded at T2-Kujram (4.43 cm) followed by T4-Kujram (4.35 cm). Maximum number of internodes was recorded at T5-Dangiadagh (17.40) followed by T4-Kujram (16.73) while maximum fresh weight/plant was recorded at T2-Kujram (61.17 g) followed by T4-Kujram (59.90 g). Maximum dry weight/plant was recorded at T2-Kujram (13.68 g) followed by T1-Tarub (13.29 g) and maximum leaf weight/plant was recorded at T1-Tarub (6.85 g) followed by T2-Kujram (6.35 g). Maximum leaf stem ratio was recorded at T36-Dulli (1.46) followed by T1-Tarub (1.43). Maximum andrographolide content was recorded at T1-Tarub (1.98%) followed by T3-Khunti-Taimara road (1.87%) and maximum neo-andrographolide content was recorded at T1-Tarub (0.41%) followed by T18-Chikor (0.30%). Correlation analysis of andrographolide content of Kalmegh with growth and yield parameters, climatic parameters, soil physical and chemical parameters revealed andrographolide content showed highly positive significant correlation with leaf stem ratio (0.762), leaf weight per plant (0.640), leaf width (0.578), dry weight per plant (0.567), stem weight per plant (0.550), fresh weight per plant (0.540), plant height (0.524), leaf length (0.512), and number of internodes (0.508). Highly significant positive correlation of andrographolide content was seen with the altitude of the collection area (0.485). Significant positive correlation of andrographolide content was observed with sand percentage of soil (0.399) and bulk density of soil (0.415), but significant negative correlation with water holding capacity of soil (-0.457). Further andrographolide content showed highly significant positive correlation with organic carbon (0.559) and available phosphorus of soil (0.631) and significant positive correlation with available nitrogen (0.427) and available potassium of soil (0.420). Regression analysis of growth parameters showed that the plant height, number of internodes, dry weight/plant and leaf weight/plant of Kalmegh had significant positive impact on its andrographolide content while, regression analysis of climatic factors with growth, yield and biochemical parameters showed significant impact of leaf weight/plant, mean temperature and altitude on its andrographolide content. Regression analysis of soil physical parameters showed significant impact of leaf width and leaf weight/plant on andrographolide content while, regression analysis of soil chemical parameters showed significant impact of plant height, leaf weight/plant, leaf stem ratio, organic carbon of soil and available potassium of soil on its andrographolide content. Path value analysis of biochemical factors with growth and yield factors of Kalmegh revealed the highest positive direct impact of dry weight/plant (5.178) followed by leaf weight/plant (4.161) on its andrographolide content. Again, path value analysis of climatic factors revealed maximum positive direct impact of leaf weight/plant (1.915) followed by altitude (0.514) on its andrographolide content. Path value analysis of soil physical parameters revealed maximum positive direct impact of leaf weight/plant (2.918) followed by plant height (0.436) on andrographolide content, while path value analysis of soil chemical parameters revealed maximum positive direct impact of leaf weight/plant (2.713) followed by plant height (0.559) on its andrographolide content. As regards to the first objective namely, morpho-biochemical diversity of Kalmegh in all three agro climatic sub-zones of Jharkhand under in-vivo conditions, highly significant difference was observed between ACZ IV & VI in leaf lamina length, leaf lamina width, length of internodes, number of internodes, andrographolide content and neo-andrographolide content of Kalmegh, whereas, highly significant difference was observed between ACZ V & VI in number of internodes and neo-andrographolide content of Kalmegh. Significant difference was observed between ACZ IV & VI in plant height, stem diameter, number of primary branches/plant, fresh weight/plant, dry weight/plant, leaf weight/plant, stem weight/plant, and leaf stem ratio of Kalmegh. Significant difference was observed between ACZ V & VI in number of primary branches/plant, leaf lamina length, leaf lamina width and length of internodes of Kalmegh, whereas, significant difference between ACZ IV & V was observed only in leaf lamina width of Kalmegh. Superior germplasm of Kalmegh identified with high andrographolide content were T1-Tarub (1.98%), T20 -Bhanrra (1.96%), T3-Khunti-Taimara road (1.87%), T41-Patratu valley (1.87%). Superior germplasm of Kalmegh identified with high neo-andrographolide content were T1-Tarub (0.41%), T18- Chikor (0.30%), T19-Bhanrra (0.30%), T20-Bhanrra (0.30%). As regards to the second objective namely, geo-referencing of morpho-biochemical traits of Kalmegh in all three agro climatic sub-zones of Jharkhand under in-vivo conditions, it may be concluded through grid mapping of 50 Kalmegh germplasm that the agro climatic sub-zone V exhibited a higher level of superiority with respect to growth, yield and biochemical contents when compared to the other two sub-zones of Jharkhand. As regards to the third objective namely, traits association studies with local climatic and edaphic conditions, following conclusion can be drawn, andrographolide content of Kalmegh showed highly significant positive correlation with altitude (0.485), which shows that the biochemical content may be found in higher amount at higher altitudes. Andrographolide contents of Kalmegh showed positive significant correlation with bulk density (0.415) and sand percentage (0.399). The andrographolide content of Kalmegh showed highly significant positive correlation with organic carbon (0.559) and available phosphorus (0.631), and significant positive correlation with available nitrogen (0.427) and available potassium (0.420), whereas andrographolide content showed a negative non-significant correlation with soil pH, silt percentage and clay percentage of soil. Analysis of 50 Kalmegh germplasm revealed that the most significant factors contributing to the diversity of Kalmegh were fresh weight/plant (36.73%), dry weight/plant (11.76%), and leaf weight/plant (10.04%) respectively. The current study suggests that the agro climatic sub-zone V in Jharkhand exhibits superior growth & yield as well as biochemical production of Kalmegh. To strengthen these findings, further investigations, such as expanding the sample size in experiments and conducting molecular analyses on Kalmegh can be conducted. These analyses will contribute to the assertion that sub-zone V is the most suitable candidate for obtaining a Geographical Indication (GI) tag in relation to biochemical, growth and yield production of Kalmegh.ThesisItem Open Access Evaluation of growth and yield performance on the spacing trial of Giloy (Tinospora cordifolia)(2022) Nawin Nikhil Kachhap; Kaushal KumarTinospora cordifolia (Willd.)

Miers ex Hook.f. & Thoms.] is a large, glabrous, deciduous climbing shrub belonging to the family Menispermaceae. The plant also known „Amirta‟, „Guduchi‟ etc. and their stem is used for formulations of many ayurvedic products for the treatment of fever and as best immuno-modulators etc. There are several pharmaceutical companies manufacturing more than 50 products available in the market. The Glioy juice along with Aloe vera, Tulsi, Amla etc. widely utilised by peoples. Nutrient management plays an important role in enhancing the yield per unit area. The concept of Integrated Nutrient Management (INM) aims at the maintenance or adjustment of soil fertility, the soil and the added fertilizer react with each other chemically and biologically. Any factor that may tend to limit plant growth will necessarily reduce fertilizer efficiency and consequently the crop response to fertilization. Appropriate amounts of fertilizers requirement can be estimated for optimum plant nutrient supply to obtain the desirable crop productivity through maximization of benefit from all possible sources of plant nutrients in an integrated manner. In Jharkhand, because of the presence of acidic soil, micro and macro nutrients are not available to plant, therefore plant growth is being affected. The application of fertilizers would be helpful to improve the physical and chemical properties of soil which are very much important to crop with different environmental factor and improve production and productivity. Information pertaining to integrated nutrient management in Tinospora cordifolia are very scanty. Therefore, present investigation was undertaken on integrated nutrient management in Giloy under rainfed condition of Birsa Agricultural University, Ranchi at AICRP (MAPS) farm. With the following objectives: - i) to find out the impact of Integrated Nutrient Management practices on growth of Giloy (Tinospora cordifolia). ii) to evaluate percentage of Giloysatva. The experiment was laid out with more than two nodes were used for propagation and field research using specified designs, treatments and replications for studies. The cuttings were planted in Randomized Block Design with 14 treatments and 03 replications at 160 cm × 120 cm spacing level on 9th April, 2019 at the experimental field of AICRP on Medicinal & Aromatic Plants (D-Block), Birsa Agricultural University, Kanke, Ranchi, Jharkhand. Area under each treatment was 3.60 m × 3.20 m = 11.52 m2 and for one replication, it was 51.8 m (length) × 4.1 m (breadth) = 212.38 m2 thus net area taken for field research was 212.38 m2 × 3 = 637.14 m2 . All six plants were selected from all the treatments for data on different quantitative aspects as per NBPGR format. Plants were irrigated regularly on alternative days except during the rainy season. Normal cultural practices such as weeding, hoeing and irrigation were given in the field. It has been observed that Maximum significant fresh stem yield 13714.40 kg/ha of Giloy was recorded in treatment combination (T14) of Vermicompost: 5 t ha-1 + Karanj Cake: 5 t ha-1 + Neem Cake: 5 t ha-1 + 15:20:10 NPK kg ha-1. The maximum dry stem yield 11067.37 kg/ha was recorded from the Treatment T13 (Vermicompost: 5 t ha-1 + Karanj Cake: 5 t ha-1 + Neem Cake: 5 t ha-1) and lowest 6964.59 kg/ha was in T1 control. Whereas grand mean value was 8408.21 kg/ha. In this way it can be concluded that Treatment T13 and T14 is better than other rest of the treatments. Maximum percentage of Giloy-satva (3.69%) of stem of Giloy (Tinospora cordifolia) was calculated from the treatment combination of Vermicompost: 5 t ha-1 + Karanj Cake: 5 t ha-1 + Neem Cake: 5 t ha-1 + 15:20:10 NPK kg ha-1 followed by 3.65% in Vermicompost: 5 t ha-1 + Karanj Cake: 5 t ha-1 + Neem Cake: 5 t ha-1. The lowest percentage of Giloy-satva (3.13%) was recorded from control. Correlation with fresh stem yield. It was observed positively correlated in all parameters like Inflorescence length (0.253), Internode Distance (0.206), Stem thickness (0.640), Collar diameter (0.501), Leaf length (0.596), Leaf width (0.389), Petiole length (0.251) and Giloy-satva (0.569). No Negative correlation was found in any parameters. The path analysis value showed that the direct effect given by Inflorescence length (0.023), Internode distance (0.017), stem thickness (0.335), Leaf length (0.311), Petiole length (0.146) and Giloy satva (-0.240) had direct positive effect on the stem yield. Two characters namely collar diameter (-0.015) and leaf width (-0.019) and showed direct negative effect on stem thickness. Maximum direct positive effect on fresh stem yield was shown by stem yield (0.335), while maximum direct negative effect was shown by leaf width (-0.019). The above studies would be significant for the farmers and medicinal plant growers, particularly of the Jharkhand state about the scientific understanding of organic and inorganic fertilizer combination to get better growth parameters of Giloy.
