Abstract

Corn (Zea mays L.) is one of staple foods. Corn is a rice supplementary food in an effort to diversify food and also raw materials for animal feed industry. More than 50% composition of animal feed are using corn as base material, and other processed industrial raw materials (Dirjentan, 2005). The demand for corn continues to increase so that it is necessary to strive for increasing corn production including proper fertilization to meet the best nutrient needs for the growth of corn plants so that it yields an optimal result. Through fertilization we can achieve the nutrient required for corn plants so it grow optimally. The use of inorganic fertilizers through the soil if doesn’t done correctly can reduce the efficiency of fertilization and disturb the nutrient balance in the soil. This study aims to determine the NPK inorganic fertilizer dosage that is effective for the growth and yield of corn plants (Zea mays L). This study used the Randomized Block Design (RBD) method, treatment A was a control without fertilizer application, treatment B use Urea 300 kg/ha + SP-36 50 kg/ha + NPK (15:15:15) 200 kg/ha, treatment C use Urea 300 kg/ha + SP-36 50 kg/ha + NPK (21:10:10) 100 kg/ha, treatment D use Urea 300 kg/ha + SP-36 50 kg/ha + NPK (21:10:10) 150 kg/ha, treatment E use Urea 300 kg/ha + SP-36 50 kg/ha + NPK (21:10:10) 200 kg/ha, treatment F use Urea 300 kg/ha + SP-36 50 kg/ha + NPK (21:10:10) 250 kg/ha, treatment G use Urea 300 kg/ha + SP-36 50 kg/ha + NPK (21:10:10) 300 kg/ha, treatment H use Urea 300 kg/ha + SP-36 50 kg/ha + NPK (21:10:10) 350 kg/ha, analyzed by ANOVA followed by a 5% DUNCAN test. The results showed that the addition of inorganic NPK fertilization with a combination of Urea and SP-36 fertilizers could increase the growth and yield of the pertiwi 3 (varieties of corn) compared with no fertilizer addition. The use of inorganic NPK fertilizer (21:10:10), combination of urea fertilizer and SP-36 fertilizer with the use of inorganic NPK fertilizer (15:15:15). Combination of urea fertilizer and SP-36 fertilizer shows that there are some results that showing the same growth and yield. The most effective dose produced the highest dry weight and shelled weight using the E fertilizer dose NPK inorganic fertilizer (21:10:10) 200 kg / ha combined with the use of fertilizer 300 kg Urea / ha + 50 kg SP-36 / ha.
