Field Guide of Discovery-based Exercises for Organic Vegetable Production
leaf-miner is a small grayish fly whose larvae mine in-between the leaf epidermis which when several of
them work in the same leaf, develop blotch and turn the entire leaf white and wither, resulting in the
stunting of subsequent growth and ultimately in poor yield.
leaf spot is a fungal disease of cucurbit and leguminous vegetables characterized by the presence of spots,
circular to irregularly shaped, with tan or gray centers, and surrounded with reddish-brown to darkbrown
margins.
leafy vegetables are vegetables grown mainly for their leaves. Some examples of leafy vegetables are
pechay, mustard, lettuce, celery, ‘kangkong’ (swamp cabbage), and ‘kulitis’ (amaranth).
learner-centered training refers to a training situation wherein participants are given the opportunity to
assume responsibility for their own learning.
learning field is that portion of a farmer’s field school measuring at least 1,000 square meters, containing
a farmer-run comparative study of integrated pest management (IPM) and farmer’s crop protection
(FCP) practices. It is in this field that farmers practice agro-ecosystem analysis (AESA) which includes
plant health, water management, weather, nutrient management, weed density, disease surveillance, and
observation and collection of insect pests, beneficial predators, and parasites. Farmers interpret data
from the learning field through direct experience using AESA to make field management decisions and
develop a vision of balanced ecological processes.
lecture method is a didactic instructional method, involving one-way communication from the active
presenter to a more or less passive audience or trainee group.
leguminous vegetables are vegetables belonging to the legume or pulse family. Some examples of leguminous
vegetables are bush long bean, cowpea, snap beans, sweet peas, garden peas, chicken peas, and winged beans.
liming refers to the addition of lime to reduce soil acidity or until the soil pH is within that required for
optimum plant growth. Available iron, aluminum, and hydrogen must be replaced by Ca and Mg bases
through liming to decrease soil acidity. Adding oxides, hydroxides, or carbonates of calcium and
magnesium commonly does this.
market chain refers to market intermediaries (e.g., households, neighbors, village collectors, traders,
wholesalers, etc.) where different types of organic products (e.g., mature, immature fruits, flowers,
leaves, etc.) pass through between farmers or producers and their different types of consumers.
market competition refers to dynamics among potential customers with similar needs and sellers offering
various ways of satisfying those needs. The development of successful market competition strategies
depends to a large extent on planner’s ability to segment markets.
market information refers to all available data from primary (e.g., obtained from new research surveys
whenever new problem arises) and secondary (e.g., often available for free, or for a fee that is usually far
less than cost of obtaining primary data) sources that can be used by marketing manager to help them
make effective marketing decisions.
