    Impact of Spacing and Type of Planting Material on Dry Matter Percentage in Cinnamon Bark: At the Stage of First Harvest
    (Faculty of Humanities and Sciences - SLIIT, 2021-03-26) Aluthgamege, H.N.; Fonseka, D.L.C.K.; Benaragama, C.K.; Kumarasinghe, H.K.M.S.
    Cinnamomum verum J. Presl (cinnamon), is an evergreen aromatic plant with several uses and considered as a prominent spice throughout the world. Most familiar product of cinnamon is quills, produced by peeling and rolling the bark pieces in to a pipe like structure. Dry mater content in cinnamon bark is a determinant factor of income since weight of quills mainly depends on it. If the dry matter content in cinnamon bark can be increased, returns from cinnamon exports can be increased as well. Therefore, this study was aimed at identifying the effect of spacing and type of planting material on dry matter percentage in cinnamon bark at the stage of first harvest. Seedlings and vegetatively propagated plants of cinnamon variety Sri Gemunu were planted under three different spacings as 1.2×0.6 m with three plants per hill, 1.2×0.4 m with two plants per hill and 1.2×0.2 m with one plant per hill as two factor factorial RCBD at the Faculty of Agriculture, University of Ruhuna, Sri Lanka. First harvest was collected after two years from establishment and quills were produced with support of skilled cinnamon peelers. Weight of quills per plant was measured after air drying for three days and dry matter percentage in bark was determined by oven drying samples to a constant weight. The results revealed that the mean dry matter percentage in bark of cinnamon seedlings (37.84%) was significantly higher (P<0.05) than the mean dry matter percentage in bark of vegetatively propagated plants (31.69%). The mean quill weight per cinnamon seedling (45.93 g) was significantly higher (P<0.05) than the mean quill weight per vegetatively propagated plant (28.40 g). Interaction effect between spatial pattern and planting material was not significant for both bark dry matter percentage and weight of quills per plant. A moderate correlation between cinnamon bark dry matter percentage and quill weight was observed at the stage of first harvest (r = 0.429, p = 0.036) according to the Pearson’s correlation test. Findings of the current study can be used for further studies.

    Analysing the Processing Ability of Cinnamon Stems Under Different Planting Systems
    (Faculty of Humanities and Sciences,SLIIT, 2021-09-25) Aluthgamage, H. N; Fonseka, D. L. C. K; Benaragama, C. K
    Cinnamon contributes largely to the country’s economy, being one of the major agricultural export crops in Sri Lanka. But shortage of skilled cinnamon peelers is one of the major problems. Therefore, enhancement of the efficiency of processing procedure is crucial. Hence, the study was conducted to optimize the processing ability of common stems based on spatial pattern, type of planting material and harvesting interval to enhance the efficiency of cinnamon processing. Seedlings and vegetatively propagated plants (VP) of cinnamon; variety Sri Gemunu were planted under three spatial patterns as (A) 1.2×0.6 m with three plants per hill, (B) 1.2×0.4 m with two plants per hill and (C) 1.2×0.2 m with one plant per hill at the Faculty of Agriculture, University of Ruhuna. Stems were harvested in two planting intervals as 6 and 8 months. The study was conducted after four years from field establishment. Harvested cinnamon stems were processed with the support of a skilled cinnamon peeler. Scraping ability, rubbing ability, peeling ability and overall processing ability were recorded based on a scoring scale as, Bad-1, Normal-2, Good- 3 and Best- 4. The results revealed that, only the impact of planting material was significant ( p < 0.05) for Scraping ability, rubbing ability, peeling ability as well as overall processing ability of the cinnamon stems. Seedlings were observed to have better ability of processing than vegetatively propagated plants. Current findings can be used for further studies on efficiency enhancement of cinnamon processing.
