2.1 Short description of the Technology

Definition of the Technology:

Cultivating a mixture of crops with different heights (multi-storey) and growth characteristics which together optimise the use of soil, moisture and space.

2.2 Detailed description of the Technology

Description:

Under the maramihang pagtatanim multi-storey cropping system, perennial crops (coconut, banana, coffee, papaya, pineapple) and annuals/biennials (root crops: taro, yam, sweet potato etc) are interplanted to maximise productivity and income. This is most applicable where farms are small and the system needs to be intensive. In this particular area, Cavite, coconuts are usually planted first. When they reach a height of 4.5 meters (after 3-4 years), bananas, coffee and/or papaya are planted underneath. Black pepper may also be part of the system. After sufficient space has developed at ground level in about three to four years, root crops are planted. At full establishment, the system develops different layers: coconut (tallest) followed by banana, coffee, papaya (middle), root crops and pineapple (lowest). In recent years, because of its relatively low productivity and decreasing price, coconut has tended to be replaced in the system with higher value crops like the fruit tree santol (Sandoricum koetjape), papaya and sometimes black pepper. However most multi-storey farms adhere to no specific planting layout. The multi-storey agroforestry system is intended to make the best use of resources (soil, moisture and space) for increased farm income. It is also very effective against soil erosion. Previously, continuous monocropping of annual crops resulted in erosion and serious soil fertility decline. Even though the land is sloping and rainfall during the monsoon is extremely intensive, multi-storey cropping provides adequate soil cover throughout the year, protecting the land from erosion.

Fertilization, weeding and pruning are necessary elements of maintenance. ‘Natural’ mulching through fallen leaves from leguminous trees helps restore and maintain soil fertility The system is applied in a volcanic-derived soil with distinct wet and dry periods (6 months wet season, 6 months dry season). There is the risk of a destructive typhoon every 10 years. Farm income is relatively high, but labour and input costs are also high - and the technology is mostly used by relatively wealthy landowners. There is strong spontaneous adoption, as maramihang pagtatanim has been proven to be effective and remunerative. This technology has been practiced in Cavite since the 1970s. Implementation is by individual farmers with strong extension support from the Local Government Units (LGUs), NGOs and the Cavite State University.

Comments:

Major land use problems (compiler’s opinion): Productivity decline, unstable prices of agricultural products and high costs of inputs are the main land use problems. Inputs also have to be increased to maintain the same yield level in annual cropping systems. There is a severe land use competition: a large proportion of the land is being converted to non-agricultural uses, especially residential and industrial areas because of the proximity to the rapidly expanding capital.
Major land use problems (land users’ perception): Productivity decline and unfavourable prices of agricultural products. High costs of inputs.

4.3 Establishment activities

4.4 Costs and inputs needed for establishment

Comments:

Duration of establishment phase: 60 month(s)

4.5 Maintenance/ recurrent activities

4.6 Costs and inputs needed for maintenance/ recurrent activities (per year)

Comments:

Machinery/ tools: animal draft wooden plough, machete, iron bar and spade, machetes, harrows, bolo.
Cost was calculated assuming a per hectare population of 100 coconuts, 400 coffee plants and 3,000 pineapples.
Maintenance activities entail more work than during the establishment phase. Note that the establishment phase usually lasts for 4-5 years, so the labour is spread, unlike during the maintenance phase when all of the components have to be attended to.
