This study aimed to determine dose combination Organonitrofos <br />fertilizers and inorganic fertilizers are most effective against the growth, nutrient <br />uptake, and yield of sweet corn. This research was conducted in November 2012 until <br />March 2013 in the Integrated Field Laboratory, University of Lampung using Random <br />Design (RBD) consisting of 6 treatments with 3 groups. Treatment A (control), B (300 <br />kg Urea ha-1<br />, 200 kg of SP-36 ha-1<br />, 100 kg of KCl ha-1<br />), C (225 kg Urea ha-1<br />, 150 kg <br />SP-36 ha-1<br />, 75 kg KCl ha-1<br />, 1000 kg Organonitrofos ha-1<br />), D (150 kg Urea ha-1<br />, 100 kg <br />of SP-36 ha-1<br />, 50 kg of KCl ha-1<br />, 1,500 kg Organonitrofos ha-1<br />), E (Urea 75 kg ha-1<br />, <br />SP-36 50 kg ha-1<br />, 25 kg ha-1<br /> KCl, Organonitrofos 2000 kg ha-1<br />), F (3,000 <br />Organonitrofos kg ha-1<br />). The results showed that treatment at a dose of 150 kg of urea <br />ha-1, SP-36 100 kg ha-1, 50 kg ha-1 KCl, Organonitrofos 1500 kg ha-1 is able to <br />increase the growth, production and sweet corn crop nutrient uptake. This treatment <br />was also the most effective treatment of the total biomass of sweet corn plants based <br />on calculations Relative Agronomic Effectivenes (RAE) that is equal to 108.573%. <br />Economical test results showed that treatment at a dose of 300 kg of urea ha-1, SP-36 <br />200 kg ha-1, 100 kg ha-1 KCl most economical compared to other treatments. <br /> <br /> Keywords: sweet corn, the combination of fertilizer, organonitrofos, nutrient uptake</p> ER -
