Abstract
The purpose of this research is to know the effectiveness of macro compound NK fertilization on growth and productivity of corn. The experiment was conducted in lowland of Banjararum Village, Singosari Subdistrict, Malang Regency on Dry Season 2016, using experimental plot measuring 6 m x 4 m was designed in randomized block with 6 combinations of fertilization, and repeated 4 times, namely: (1) A (0 kg Urea/ha + 0 kg SP-36/ha + 0 kg Ponska/ha + 0 kg NK/ha), (2) B (300 kg Urea/ha + 50 kg SP-36/ha + 200 kg Ponska/ha + 0 kg NK/ha), (3) C (300 kg Urea/ha + 50 kg SP-36/ha + 0 kg Ponska/ha + 200 kg NK/ha), (4) D (275 kg Urea/ha + 50 kg SP-36/ha + 0 kg Ponska/ha + 300 kg NK/ha), (5) E (250 kg Urea/ha + 50 kg SP-36/ha + 0 kg Ponska/ha + 400 kg NK/ha), and (6) F (225 kg Urea/ha + 50 kg SP-36/ha + 0 kg Ponska/ha + 500 kg NK/ha). The results showed that macro compound NK fertilization with enhanced administration was accompanied by the addition of growth and analysis of the growth of corn. In the treatment of F that is giving 500 kg/ha of macro compound NK fertilization with 225 kg of Urea/ha and 50 kg SP-36/ha obtained an increase in yield of 11,200 kg/ha dry seeds with the profit of corn farming Rp. 1,905,000 per hectare
