4.3 Ethno-botanical aspects on rice planting methods, rice production and management as to nutrient, pest, water and time management within the technological interventions of a Location Specific Technology Development (LSTD) framework.
4.3.1 Indigenous Rice Farming In Upland
Farmers for upland rice farming follow the “hasok” method. They first clean their farms and remove the plants within that area, this cleaning procedure is done in a direction suitable for the farmer, some are doing this in upward direction and others in a downward direction. After this they are going to burn the plants within that area, some burn it directly, while others put those plants in one area before burning them. After this, the planting of rice through “hasok” method follows. They use small sticks to make a hole one to two inches in size, and placed the rice seeds directly in the hole, some cover the hole with little amount of soil while others just let it open.
“Hasok” method of farming is done in a downward direction. After this the seeds will just grow in time that it is favourable for its growth, in these the seeds adopt itself to the soil. After one week or two, depending on the weather condition the rice can already be seen above the ground. The farmers just let the rice without treating any fertilizer, pesticide, or even watering the plants. For about 4 to 5 months waiting for the
17
harvest they just visit their farms weekly or twice a month, some of the farmers remove the weeds whenever they visit, but some of those remove the weeds at the first 2 to 3 months on which the indigenous rice are in short height, but when the rice plant are already tall in height, the weeds are no longer removed since they do not affect the rice plant anymore. In the harvest time, farmers used “gagta” to get the rice. After this they will plant other crops instead of rice to retain the nutrients in the soil. This kind of farming mostly occurs once a year, from the month of April or May up to September to October.
4.3.2 Problems Encountered In Upland Rice Farming
• On pests (rats and maya birds)
Before, pests are not a major problem in upland rice farming. Even though there are pests, it does not give too much effect in their harvest. But as the years go by, increase in pests population are observed, there are also decrease in upland rice farmers that makes it difficult for the existing farmers because the pests go in their farm.
• Weather condition
Indigenous rice varieties can be harvested 4-5 months after planting. In these long period of waiting there are a lot of chances that the rice plants will be destroyed by the typhoon. In the previous years, effect of climate change is also observed, in which typhoon came in unexpected seasons, and no rainfall a long period of time that makes the rice plant die due to too much heat.
4.3.3 Indigenous Rice Farming In Lowland
In terms of the farming procedure of indigenous rice varieties in lowland, it is similar with the modern rice varieties, by “Tarok” method. The difference is they used less amount of water for this variety because they thought that this kind of rice is not suitable for farms with too much water knowing the drought tolerance of these rice varieties. Indigenous rice has also less pests than modern rice that makes the farmers used just a little amount of pesticide for their plants. They used the same amount of fertilizer as to the modern rice varieties.

In many parts of South Asia (SA) and South East Asia (SEA), the comeback of traditional rice varieties in the production of rice becomes a controversial decision. For instance, Bengwayan (2010) of Ifugao has campaigned and became successful to some extent in convincing the return of native varieties which are now at the brink of disappearance and might lead to extinction. In other SA countries like India, the hybrid revolution of rice has forced the local farmers to abandon the native varieties of rice which are known to possess some genetic traits making these rices to have greater advantages for cooking and eating features. However, few studies are being supported now to focus on the comeback and this present study in San Andres contributes to this growing body of knowledge and interest about IRCs in this island. The local farmers of San Andres (n=40) provided the researchers (with student (EAE) and youth co-operators) with different insights on the reasons why there is a decreasing trend in the use of IRCs. Table 16 presents the responses.
Table 16. Statements Based On The Narratives Given By The Local Rice Farmers As To The Decrease In Using Indigenous Rice Varieties Or The Discontinuation Of Traditional
Rice Planting Methods Which Takes A Longer Period
Reasons of Discontinuation of Using IRCsWe are already old and bodies are too weak to continue doing rice farming tasksWe receive less support from the government since the hybrid or HYV are being recommendedLocal farmers opt to use modern or hybrid rice varieties because they can harvest about 3 times a yearIncreasing rice farming problems on pests and extreme weather conditions of continuous rain or flooding.They could not sell their indigenous rice at high price, less buyers of these rice varieties because people nowadays are not aware of these traditional or indigenous rice varieties.
4.3.5 Some Rice Production and Management Practices of the Rice Farmers
Time Management
Most of the upland rice farmers plants rice once a year. Then they plant other crops after rice, such as sweet potato. In the usual once a year upland rice farming, the planting seasons are in the month of April to July, and the harvest time is from the month of August to December. Some farmers plant twice a year. First, on June and harvest at October or November. Second, on December and harvest at April or May. Lowland farmers of indigenous rice plants have cropping of twice a year.
Water Management
23
Indigenous rice varieties do not require too much water. In upland farms, farmers do not water the rice plant, rain is the only source of water by the plants. Some upland rice farms are near to bodies of water, like rivers and falls. This good location is favorable for the healthier growth of the rice plant. Lowland rice farms used little amount of water from the irrigation, spring, and other water source, but just enough water to prevent the plant from drying.
Nutrient Management
Most of the upland rice farmers do not put fertilizer in their plants because the soil in the mountain is very favorable for the healthier plant growth. Some of the upland rice farmers also used urea once before they plant rice. Lowland farmers of indigenous rice used urea and ammonia, but only a few amounts compared to lowland rice varieties today.
Pests ManagementPests in upland rice farms are rats, maya birds and some insects. For the rats, some used
rakumin for poisoning, but most used “atipil” - mouse trap to catch the rats. Some farmers make a smoke in the surroundings of the farm, to make the pests leave the place. Few used starfish at the different points on the farm, because they believe that its smell doesn’t like by the pests.
Table 17 shows a straightforward estimation of the reduction in the number of indigenous rice farmers in the 5 barangays from 1960 to 2012 based on timeline analysis. The introduction of hybrid rice varieties from 1980s to 1990 could be shown in much lower number of farmers abandoning the use of IRCs, but to shown even distribution in the timeline, fewer number of farmers were believed to be reflected.

In Table 18, the estimated selling prices of IRCs are presented, with the hope to explain how these farmers use the economics aspects of IRC production in deciding to shift to the other varieties. However, if government campaigns on the traditional rice comeback will be carried out or even the university will be engaged in this endeavour of focusing on IRCs production, then the trend in Table 17 could be reversed or number of farmers will retain through awareness program. Financial support is therefore necessary in this regard and with the addition of other livelihoods to avoid the kaingin or “Hasok” method.

CONCLUSIONS AND RECOMMENDATIONS
Based on the results presented, it can be concluded that a greater number of IRCs totalling to 39 IRCs are still available in the barangays covered during the study. Characterization of seeds shows that different indigenous rice cultivars have their distinct morphological characteristics in terms of color, structure, texture, weight, length, diameter, and many others. There are significant differences among the three germination types; in terms of germination percentage, length of root and shoot growth, and survival percentage. Germination percentage is favoured in germination in water, length of shoot and root growth favoured in germination by “sabwag” method, while the survival percentage favoured in germination by “hasok” method. “Hasok” method is the best germination type that will lead to many number of living rice plants. Ethno-botanical practices of indigenous rice farmers in San Andres,
25
Catanduanes are almost similar to each other, although there are just few of them used different way of farming.
The present findings in the study are worthwhile inputs to the location-specific technology development adoption among farmers in Catanduanes. These are also valuable inputs to the bio-techno guides of the Catanduanes State University which are now being processed and re-packaged for the printing of brochures and field guides. Four statements based on the farmers’ narratives were formulated, namely:
1) Water requirement and pests are not problematic as to the use of IRCs in rice production. As such, bio-techno-guides are expected to focus on how integrated water management can be practiced with IRCs and the use of the marine bioresources (e.g. use of starfishes, sponges and other Cnidarias) in discovering natural pesticides to eradicate these limited rodent pests and birds.
2) With the limited number of cropping, production of IRCs can be maximized by establishing IRC plantation areas in the province which will have governmental or NGO support with CSU’s intervening mechanism or the establishment of an Indigenous Knowledge Research Center with indigenous rice as a flagship project.
3) Nutrient management and varietal status as important components and appear to be the most problematic in the LSTD interventions, efforts on R&D are to be focused with IRC in Catanduanes. With the indigenous rice comeback in Catanduanes, the practice of kaingin with “Hasok” poses serious threat.
4. The economics of IRC cultivation in Catanduanes was found to be the most important statement based on farmers’ narratives. It is therefore imperative to provide empirical data as to the use of IRC in rice production by placing some economic valuation on the costs of conserving the genetic resource, production of highly nutritive IRCs and organic farming production with IRCs. More programs and studies are needed to improve the indigenous rice farming industry, and to open diversified livelihoods for the indigenous rice farmers through microfinancing.
