Duration of the biological cycle and its phenophases for INCA-17 variety in monoculture and polyculture systems out of the optimal period
Main Article Content
Abstract
at the National Institute of Agricultural Sciences, a study was
carried out to determine the duration of the tomato variety
INCA-17 biological cycle and its the different phenological
phases in two cropping systems: monoculture at full sun
exposure and polyculture using maize as natural shade, with
the objective of evaluating phytoclimatical modifications in
both systems and plant response to these modifications in
each phase. The spatial arrangement for polyculture consisted
of two maize rows on both sides of three tomato rows, where
maize was seeded 30 days before trasplanting tomatoes and
all the rows were oriented N-S. Results showed differences in
the duration of crop biological cycle for both sowing periods,
which had nothing to do with the average air temperature
throughout crop cycle, but with the duration and average air
temperature on each particular phase; also, the type of
agricultural system caused a differentiated biological plant
response through yield and its components. Results proved
the convenience of using systems that modify phytoclimate
to obtain higher yields than the ones from monoculture
plantations in the nonoptimal period.
