The cocona (Solanum sessiliflorum Dunal) is a source of plant domestication and
Amazon, with the potential for agribusiness. It is usually grown in the open on the
mainland. However there are few studies phytotechnical that enable increased fruit
yield. This research aimed to evaluate the cubiu cultivation under the influence of drip
irrigation in greenhouse conditions in the city of Manaus / AM. The experiment was
conducted in a greenhouse in Acrisol Alic, in Manaus. Adopted the Experimental
Design completely randomized in a factorial design with 3 irrigation levels and 4
varieties of cubiu with 5 repetitions. As each blade applied with a drip tape type with
the emitters 10 cm spaced, 20 cm and 40 cm, corresponding blades 50%, 100% and
150% (ETc), respectively. The following traits were evaluated: average number of
fruits, fruit diameter, fruit length, average fruit weight and length / diameter of the fruit.
The applied water depths did not influence significantly the production of fruit. This
indicates that the cubiu can be irrigated with a water slide 50% evapotranspiration
without prejudice to the production of fruits per plant. The productivity components,
there was a slight tendency of the blade equivalent to 150% of ETc influence the
greatest number of fruits per plant. On the other hand, the blade equivalent to 100%
of Etc gave the highest mean fruit weight and promoted a yield of 4 tons per hectare.
Finally, the shape of fruit evaluated by the length-to-diameter ratio was not influenced
by controlled irrigation, indicating that variation may be due to genetic effects of
accessions. |
