摘要：Potatoes (Solanum tuberosum L.), one of seven horticultural
products targeted to be developed in 2015 by Directorate General
of Horticulture. Pasuruan Regency was be able to produce potatoes
up to 50% of the total potato production in East Java. Although
potatoes cultivation in the Tosari District is relatively large, potatoes
productivity is still a problem for the farmers. This study was aimed
at analyzing the factors of production that had a dominant influence
on potato production and its technical efficiency in the Tosari
Village, Tosari District, Pasuruan Regency. Sample was determined
by simple random sampling and amounted to 30 potato farmers.
Data were analyzed with multiple linear regression models.
Analysis revealed that the significant factors affecting potato
production in Tosari Village were urea, SP36, ZA and manure.
Application of urea, ZA and manure in potato farming in Tosari
Village had not been efficient, so it can be added. Meanwhile, SP36
fertilizer was still applied inefficiently, so it must be reduced.
