Local knowledge in rubber (Hevea brasiliensis) farming systems in Sri Lanka: applications and constraints

AbstractMeekiri (sometimes also known as Mee-Deekiri); fermented buffalo milk gel is a deep-rooted dairy product in Sri Lankan food culture and the production of Meekiri plays an integral part in the livelihood of rural farming. Meekiri consumption is widespread irrespective of geographic boundaries, across the cultural and/or ethnic communities. In Sri Lanka, buffalo milk is predominantly used in producing Meekiri, where production has been specialized in various geographic areas in the country, associated with major buffalo farming regions. Physicochemical and microbiological quality attributes are apparent to differ in Meekiri according to varying production regions, processing techniques and storage conditions. The mouthfeel and taste of Meekiri are widely accepted to be thicker and creamier with a pleasant note and is whiter in colour compared to fermented cow milk gel/yoghurt. Since Meekiri production is localized in Sri Lanka and available as traditional know-how at the primary production level, up-to-date comprehensive scientific literature that accounts for processing and detailed product quality characteristics is lacking. Hence, this review evaluates and outlines updated information about the Meekiri production, associated buffalo farming systems, quality characteristics of Meekiri including physicochemical, sensorial and microbiological aspects in the final product.

Abstract L. speciosa is a medium-size to large deciduous tree distributed throughout India, Myanmar, Sri Lanka and Bangladesh, except for dry areas. The rate of growth is moderate and the trees grow best on deep, rich, well-drained alluvial loam, with sufficient moisture. The timber is used for buildings, ships, boats, dug-out canoes, bridges, water tanks, railway wagons, bus bodies, turnery, cooperage and many other purposes. L. speciosa is suitable for afforestation of sites prone to dampness and waterlogging, and can be grown successfully from seed, seedlings and stump plants. It is used in farming systems, as it is particularly suited to paddy rice agroforestry. L. speciosa is one of the most beautiful ornamental trees when in flower and is widely planted in India in gardens, parks, homesteads and avenues.

Pests And Diseases

Green gram (Vigna radiata (L.) R. Wilczek) is one of the most economically important grain legumes of the traditional farming systems of Sri Lanka because it is a cheap source of protein and animal feed, and sustains soil fertility by fixing atmospheric nitrogen. Weeds are one of the major problems in green gram cultivation, reducing the yield through competition, interference with harvest and harboring pests and diseases. Controlling of weeds by applying herbicides would definitely cause unexpected damage to human health and the abundant biodiversity of Sri Lanka. Therefore, an investigation was planned to evaluate the yield loss due to weeds and to determine the optimum weed free period to minimize the yield losses. Two experiments were performed. The first experiment was conducted to determine the effects of different weed functional groups on the yield of green gram. In the second experiment, weeds were continuously hand weeded and areas kept weed free. In the third, weeds were allowed to compete with green gram until 2, 3, 4, 5 or 6 weeks after cultivation. All the treatments were conducted in randomized complete block design with three replicates. The data collected on types of weed, number of pods and pod weight at 3–6 weeks after planting (WAP) were analyzed using the SAS 9.4 statistical package, and DMRT was performed to determine the best treatment combination. The results from the first experiment showed that average yield loss due to total weed populations was 54.77%. Yield loss due to grasses alone was 46.56%, far worse than broad leaves (16.49%) and sedges (18.01%) at p < 0.05. Crop stand count at 3–4 WAP was not significantly different among treatments. However, biomass weight of 50 plants, number of pods in 50 plants and grain weight of 10 plants were found to be significantly different after 3–4 WAP in weed free conditions at p < 0.05%. When the weed free period increased, the yield was increased until 3 WAP; thereafter, not significant yield increment was observed. In contrast, yield steeply declined in plots that had weeds until 3 WAP. According to the results of the present study, it can be concluded that the critical weed free period from the planting of green gram is 3 WAP. Maintaining a weed free period for 3–4 weeks is recommended to minimize the yield loss of green gram at minimal weed management cost.
