Resumo
There are few studies of coffee intercropped with banana and rubber trees, thus
shaded coffee studies are important for a better understanding of the systems.
The objective was to study the effect of intercropping with banana and rubber
trees in coffee Conilon, making a micro-climatological characterization. This
study was conducted in three fields: 1) Conilon coffee (Coffea canephora),
planted in late 2006, intercropped with syringe (Hevea brasiliensis) planted in
late 2007, this syringe planted in double rows (33m x 3m) , with 2.3 m between
plants, coffee with spacing of 3m X 1m. 2) Conilon coffee, planted in full sun in
late 2006 with a spacing of 3.0 X 1.1 and another coffee plantation intercropped
with syringe with the following spacings 2.6 and 7.8 X 1.3 X 2.3 m . 3) Conilon
coffee intercropped with banana (Musa sapientum subgroup Earth) with a
spacing of 3.5 x 1.2 and 1.5 x 10.5 with 1 year of age. The crops were planted
in east west direction. We measured solar radiation, temperature and relative
humidity in January (summer) and September (winter) 2012. We also
conducted evaluation of leaf nutrient content, measurement of primary branches
and internodes of orthotropic, leaf area and estimation of chlorophyll a, b and
total trees in the summer and winter of 2012. The shading directly influence the
micro-climate, reducing solar radiation, temperature in summer and winter and
increased humidity. The branches and leaf area suffered influences of shading,
the largest occurring shading of branches and leaf area in plantations shaded.
The macro and micro nutrients were influenced by leaf shading, showing higher
values in shaded plantations with rubber for Fe and Mn. The levels of
chlorophyll b and total estimated were higher in full sun in summer and winter.
