    VERMICOMPOSTING OF DIFFERENT AGROFORESTRY SOURCES BY EISENIA FOETIDA (Accession No. T06719)
    (dbskkv., Dapoli, 2019) MAHALA, VRUSHALI RAGHUNATH; Dalvi, V. V.
    An experimental study was conducted during 2017-18 at the research farm of All India Coordinated Research Project on Agroforestry, College of Forestry, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, Maharashtra to assess the “Vermicomposting of different agroforestry sources by Eisenia foetida”. The experiment was laid out in a randomized complete block design with fourteen treatment and two replications. The treatment comprises viz. T1- Guinea grass (Megathyrsus maximus), T2-Sitaria grass (Setaria sphacelata), T3-Fulgavat (Themenda moynii), T4-Mangium (Acacia mangium), T5- Glyricidia (Glyricidia sepium), T6- Coconut (Cocos nucifera), T7-Mango (Mangifera indica), T8-Jambhul (Synzygium cumini), T9-Asana (Bridelia retusa), T10-Ain (Termenelia tomentosa), T11-Bamboo (Dendrocalamus stocksii), T12-Paddy (Oryza sativa), T13-Finger millet straw (Eleusine coracana) and T14-Shivan (Gmelina arborea). The higher microbial community (viz., bacteria, actinomycetes and fungi), vermicompost decomposition rate, production of vermicompost, earthworm population and also higher availability of ammonical nitrogen, phosphorus and potassium as well as total nutrients content in vermicompost were recorded in four species namely Megathyrsus maximus, Setaria sphacelata and Glyricidia sepium out of fourteen species. Among the various agroforestry residue species, grass residue species are decomposed very fast than forest trees residues species. The recycling and higher vermicomposting production can be achieved by using of grasses than forest species within short duration. In contrast to some nutritious species i.e. Gmelina arborea and Termenelia tomentosa were observed less decomposition rate but nutritional qualities in prepared vermicompost is very high than grasses species. According to recorded C:N ratio of vermicompost, the maximum improvement in Microbial C:N ratio and C:N ratio of vermicompost were recorded by grasses and in some cereals than other species. It can be concluded that, overall maximum production of vermicompost, numbers of earthworms population, decompositions, nutrient content, microbial activities, enzyme activities and C:N ratio of vermicompost were recorded by the using of only Megathyrsus maximus, Eluecine coracana, Themenda moynii, Setaria sphacelata, Gmelina arborea and Termenelia tomentosa. Than other the indigenous and easily available farm waste agroforestry species in Konkan region, mostly in case of grasses i.e Setaria sphacelata, Themenda moynii and Megathyrsus maximus highly nutritious species i.e Termenelia tomentosa, Gmelina arborea can be more useful for the farmers for recycling and preparation of quality vermicompost within short duration and it will be more applicable for crop production in future.

On an average annual rainfall ranges from 3000 to 3500 mm. It has rich diversity of flora and fauna. Most of the plant communities belongs to the evergreen type, one of them Michelia champaca L. (Magnoliaceae) was selected for the study. It is native to tropical and subtropical South and South-east Asia. Species of flowers having some important medicinal and essential values. The experiments were conducted in the experimental farm of Pitambari farm house, sakhaloli, Tal. Dapoli, District Ratnagiri of Maharashtra from May 2018 to April 2019. At the spacing of 3mX3m, totally 124 plants of Michelia champaca were selected on the basis of girth ranges (45 to 85mm). There are twelve treatments having source of N, P and K. each treatment have four replications. Pruning was done at the height of four and six feet exception of absolute control. The observations recorded on vegetative, flowering and yield parameters of Michelia champaca L. The experimental results revealed that, among the six treatments N1 is superior over the rest of (split dose) treatment in number of flower per hectare (4321.14 ha-1), N3 for number of flowers per stem (8.08 numbers) at north direction, N4 for leaf area (42.19 cm2) and number of flower per plant (30.94 numbers), N5 for number of tertiary branches (105 numbers), per cent flowering (59.74 %) and flower width (1.53 cm), N6 for flower length (4.26 cm), shown the maximum growth rates. Similarly, in pruning operation P1 is superior over the rest of (split dose) treatment in number of flower per hectare (4314.34 ha-1), number of flower per plant (32.00 numbers) in the month of September, flower width (1.50 cm), flower length (4.02 cm), per cent flowering (58.85 per cent), leaf area index (0.041), flower per stem (7.80 numbers), leaf area (37.64 cm2), number of tertiary branches (110.38 numbers), P2 for plant height (2.56 m). In control, N2 is superior over the rest of (control dose) treatment in plant height (2.55 m), N5 for plant spread (2.77 m) at north-south direction. P3 superior over the rest of treatment in plant spread (2.56 m), flower per stem (7.80 numbers) in north direction. Place: Dapoli Signature Date: (Wahurwagh Prasik Prakashrao)

    “STUDY OF PLANT DIVERSITY, ABOVE GROUND CARBON SEQUESTRATION POTENTIAL AND FOOD VALUE OF TRADITIONAL HOMEGARDEN SYSTEM IN RATNAGIRI DISTRICT”
    (dbskkv., Dapoli, 2018) SANGARE, SIDDHESH MANOHAR; Narkhede, S. S.
    Homegarden is the multi-storey agroforestry system cultivated and maintained around the homestead by the members of family specialized by its complex structure. It provides basic things for the day to day life of the family. Homegardens are mainly found in humid tropical climate. Ratnagiri district also has humid tropical climate. Traditionally cultivated homegardens are commonly found in the Ratnagiri district and shows great variation in their composition and function in throughout the district. To document plant diversity, carbon sequestration and food value of the Ratnagiri district the present study was undertaken. For that I had divided the district area in 3 regions namely Costal (R1), Middle (R2) and Eastern (R3). Sampling units (Each homegarden) were selected in such a manner that one taluka contain five villages and each village contains six homegardens. Similarly for regions each region contains 15 villages. Finally total 270 homegardens from 45 villages of 9 taluka‘s of Ratnagiri district was surveyed. Range of homegarden area of surveyed home gardens is 0.01 acre to 1.1 acre. Coastal region shows larger size homegardens than other to region. Survey of homegardens revealed that total 209 plant species representing 178 genera and 81 families were recorded in survey of 270 homegardens of Ratnagiri district. Out of which 88 species of tree were recorded followed by 70 herb, 28 climbers and lowest 23 of shrubs. Fabaceae plant family contain highest (18) numbers of individuals followed by Cucurbitaceae (10). Analysis of diversity shows that diversity of various life forms of the homegardens shows dynamics according to various locality of the Ratnagiri district. Dapoli taluka contain highest numbers of tree (56), shrub (16) and herb (42) species, maximum numbers of climber species were recorded in Chiplun (15) taluka. Maximum numbers plant species of all life forms found in the Middle region (R2) i.e. 168. Middle region (R2) has highest (68) species of tree and (62) species of herbs assemblages. Shrub species are highest in Coastal region (R1) i.e. (22). Eastern region (R3) has maximum numbers of the climber species (23). Shannon diversity and Simpson‘s dominance indices were used to determine the diversity in the homegardens. Lanja taluka has maximum diversity of tree assemblage. Dapoli shows maximum diversity of shrubs. Chiplun shows more diverse herbs and climber assemblages. Guhagar has highest dominance of tree, herb and climber assemblage. Shrub dominance was highest in Sangameshwar taluka. Plant diversity in homegardens in region of Ratnagiri shows that Eastern region (R3) has maximum diverse tree assemblage. Coastal region (R1) has maximum shrub diversity. Herb diversity in Middle region (R2) shows slightly more diversity of herbs than other regions. Climber diversity is more in Eastern region. Dominance of trees is highest in Coastal region (R1). Shrub and herb dominance is more in the Eastern region (R3). Middle region (R2) has highest climber dominance. Relation between homegarden size and diversity is correlated by plotting graph area against diversity and result shows that Tree diversity sows stability even the area increases. This is because of increase in plantation one or two species in homegardens. Shrubs diversity shows increasing trends upto one acre after that decreases as area increases. Diversity of herbs and shrubs shows increasing trends as area increases. Plants having food and ornamental value has highest demand shown in graph of uses of plants. Importance value index (IVI) of trees shows Arecanut has highest value in tree assemblages. Jaswand has maximum IVI value in shrubs. Highest IVI value of herbs has Alu. Lima beans show highest IVI value in climber assemblage. Species having food value show maximum IVI values except shrub assemblage. Above ground sequestrate carbon stock of taluka‘s shows homegardens of Ratnagiri (75.8 tonne) taluka has maximum carbon stock followed by Guhagar (71.56 tonne). Region wise carbon stock distribution shows Coastal region (R1) shows maximum carbon stock (152.31 tonne), followed by Middle region (R2) (86.47 tonne). Area-Carbon relationship shows that as area of homegardens increases then carbon stock of the homegardens is also increases. In the homegardens of Ratnagiri district total 117 cattle‘s, 235 hen and 22 buffalos were recorded. Only 4 individuals of goats were recorded in Rajapur taluka of Eastern region (R3). Nutritive profile of food products produced in the homegardens shows that they help to nourish family of the owner. Commercial status of food products of homegardens shows that homegarden system is subsistence level agroforestry system.
