Abstract

Fertilizationis a means or method used for fertilizer through the leaves and plant part slain.The purpose of this study was to determine the frequency of fertilization and foliar fertilizer concentration is best for seedling growth aloes (A. malaccensisLamk.). The samples used were aloe plant seeds that have been aged 3 months were taken from CV. Earth Partners II, Land of a Thousand Village, city Binjai, North Sumatra. Nursery heldon the 4th floor of buildings Forestry Faculty of Agriculture, University of North Sumatra, which was conducted in November-January2013. The results showed that the frequency of the treatment of liquid foliar fertilizer application significantly affected the height and number of leaves.Treatment of liquid foliar fertilizer concentration significantly affected the number of leaves.The interaction frequency and concentration of liquid foliar fertilizer application significantly affected height and number of leaves.   Keywords: fertilization, agarwood, frequency, concentration

Abstract

The effect of grain texture on several comodities to adult of Sitophilus oryzae L. (Coleoptera:Curculionidae) in laboratory” supervised by Syahrial Oemry and Yuswani Pengestiningsih. Thisreseach aims to know the effect of grain texture on several comodities to adult of S. oryzae. Thiswas done in Laboratory of Perum Bulog Kantor Divre SUMUT Medan since January untill March2013. The method of this research was Completely Randomized Design Non Factorial with eighttreatments and three replicants.The results showed that treatment of P5 , P7 , P1 , P3 at 165.33 ,163.33 , 150.00 , 78.67 tail, in the treatment greatly affect breeding S. oryzae . Whereas the finetexture of flour showed a decrease in population size in the treatment P2, P4, P6, and P8 at 8.33,8.33, 10.00, 10.00 tail . Texture on the surface of each type of feed greatly affects the proliferationof pests powder S. oryzae .Keywords:Texture of media, S. oryzae.
