CULTURAL MANAGEMENT PRACTICES IN RELATION
TO MORPHOLOGY AND GROWTH STAGES OF
ORGANICALLY-GROWN SELF-POLLINATED VEGETABLES
BaCKGroUND aND raTIoNalE
Organically-grown self-pollinating vegetables are vegetables
wherein pod or fruit setting results from union of female
(ovule) and male (pollen) reproductive cells of same plant,
variety, or cultivar. The most common self-pollinated
vegetables are those belonging to legumes and solanaceous
crops. Populations of self-pollinated plants usually consist
of mixture of many closely related homozygous lines,
which, although they exist side by side, remain more or less
independent of one another in reproduction. Individual plants
are likely to be homozygotes. Within these species, a goal of
most breeding programs is to produce a pure line 117 .

when is this exercise most
appropriate?
ɶ In FFS, TOT, and
VST sessions, when
participants decided to
organically-grow selfpollinating
vegetables
(e.g., snap bean, garden
pea, tomato, bell pepper,
and eggplant) in learning
field or these vegetables
are organically-grown in
adjoining fields; and
ɶ When farmers want to
learn innovative cultural
management practices in
relation to growth stages
of self-pollinating organic
vegetables from other
farmers.
Some examples of legume vegetables are snap bean and
garden pea while those of solanaceous vegetables are tomato,
bell pepper, and eggplant. Just like leafy vegetables, some self-pollinated vegetables such as eggplant
and tomato are usually grown organically in home gardens to effectively use land and family labor.
However, several self-pollinated vegetables such as snap beans and green pea are considered highvalued
crops and are normally grown by farmers in commercial scale.
In commercial growing of organic vegetables, appropriate and location-specific cultural management
practices must be employed at different growth stages of crops to ensure more productive and profitable
undertakings. Innovative cultural management practices that are more adapted to various stages of
organically-grown self-pollinated vegetables had evolved in the Cordilleras through farmers’ years
of experiences. These unique experiences can be regularly shared among farmers in FFSs to further
improve current practices. The foregoing exercise was designed to achieve this particular objective.
