The climate factors is very influental to the growth and productivity of sugarcane. Rainfall is an important climatic element observed. The purpose of this reseach was to determine the effect of rainfall and rainy day as well as the correlation of both on sugarcane yield. This research was held at PTPN II Unit Kwala Bingai District Langkat Province of North Sumatera from Mey 2015 to Agustus 2015. The primary data for analytical purposes include sugarcane production; rainfall; and rainy days in 2009, 2010, 2011, 2012, 2013 at 6 locations. The result showed that rainfall and rainy days had not give contribution to sugarcane production. Based on regresion analysis at α = 0,05 rainfall as well as rainy days have low correlation to sugarcane yield.Keywords: rain fall, rain day, production of sugar cane.

Response of Three Soybean Varieties as Intercrop in First Immature Periode of Rubber Tree to Rhizobium Application, supervised by Lisa Mawarni, Luthfi Aziz Mahmud Siregar and Radite Tistama The aim of this research was to determinate the growth and production effect of three soybean varieties (Glycine max (L) Merril) on the rubber plant inter row in first immature periode of rubber (Hevea brasiliensis Muell) plantation. This research was conducted at the Sunge Putih Research Centre with altitude ± 80 m above sea level, in August until November 2014. The research was using a block randomized design with two factors and three replications. The first factor was variety IPB 1, Wilis, Anjasmoro and the second factor was Rhizobium (Density 109g or ml/plant) then without Rhizobium. The results showed that the differences in varieties had significantly effect on plant height of age 2-5 (week after plant), age 2-3 (week after plant), summarize of leaf area, mean number of productive branches, root fresh weight, root dry weight, and weight of 100 seeds per plot. Inoculation rhizobium significantly effect on summarize of leaf aera and mean number of productive branches. Interaction of the two factors had not significantly effect to all parameters were observed.
