Pertumbuhan Dan Produksi Jagung Hibrida Pada Berbagai Campuran Pupuk Kandang Sapi Dan N, P, K, Mg

The purpose of research is to find out the growth and production of hybrid corn at various manure cow mixture and N, P, K, Mg. This research was conducted at Tanjung Anom Village from October 2015 until January 2016. This research used non factorial randomized design, Application of manure cow mixture and N, P, K, Mg significant effect to plant height 6, 7 WAP and stem diameter. Application of manure cow mixture and N, P, K, Mg was not significant effect to leaf area, number of rows per cob, cob diameter, cob length, dry root weight, dry seeds weight per sample, dry 100 seeds weight, production per plot, production per hectare. The best application of manure cow mixture (5 ton/ha) + N (300 kg urea/ha) + K (120 kg KCl/ha) + Mg (400 kg Dolomit/ha) was 9,20 ton per hectare
