Preliminary experiments with potato irrigation
Geraldo B. Barreto; Olavo José Boock
SUMMARY
The purpose of this preliminary test was to study the effect of irrigation in the yield of potato during the dry season (April to August), in presence or absence of different kinds of fertilizers.
Extemporaneous rains and frost damaged the tests resulting in low production. Nevertheless it was possible to draw out valuable informations.
On the three-year period of the experiments the average increase in yield in the unfertilized plots was of about 226% in favor of the irrigated ones.
Following the irrigation in importance phosphorus contributed to increase the yield of potato tubers. Nitrogen and potassium in spite of yield increase, were less important.
The results show that about seven days is the best interval between irrigations for the soil studied, a silt loam soil, located at the Agricultural Experiment Station, at Monte Alegre do Sul.
