Abstract

This paper aims to understand the temperature and precipitation influence over the Second Harvest Corn cultivation in Londrina, Parana State, Brazil. This cultivation has shown an increase of over 10.000% in the municipality's production area from 1985 to 2013. Is was analyzed the secondary data considering the total annual crop production; yield; plantation area (ha); harvest and crop lost from SEAB/DERAL. It was considering the same period to collect the temperature and rainfall daily data provided by IAPAR. Statistical methods were used to establish correlations between the productive and climatic variables, specially the water balance technique. As conclusion, it was possible to verify that low rain totals in specifically plant phenological periods can affect negatively the crops, causing losses in production totals
