Abstract

Rizky Kumala Dewi. 138210062. Respon to growth and production of sweet corn corps ( Zea Mays L.Saccharata Sturt ) against the application of organic fertilizer liquid waste cubise and compost of empty palm bunches of palm oil. Research conducted in agriculture village Martebing, Dolok District Still Serdang Bedagai District with altitude 12 m suface sea. Purpose of thisresearch to know influence of organic fertilizer dissimilar liquid waste and empty bunch oil palm as a medium to grow crops to the growth and production of sweet corn. The research was carried out by using factorial randomized block design with the investigated fact that is the treathment of POC layers and the compost factor of empty palm oil bunches.The treathment POC cubic ( B ) is : B0 = No Treathment , B1= 125 cc/l water, B2= 250 cc/l water, B3= 375 cc/l water and Treathment Compost of empty palm oil (T) is : T0= No treathment, T1= 1 kg/plot, T2= 2 kg/plot,T3=3 kg/plot. Parameters observed were plant height , leaf number, stem diemeter, ear length, tuna weight. The result showed that the treathment of POC of cubic waste until the consentration of 375 cc/l water and compost of palm oil empty bunches with doses up to 3 kg / plot corn increase plant height, leaf number, ear length, and tuna weight.
