Abstract

Corn (Zea mays L.) is an important food commodity. This study aims to determine the effect of bottom leaf defoliation and the ratio of NPK Phonska and guano fertilizer doses on the growth and yield of corn plants. This study was arranged using factorial RAK with 2 factors. The first factor is the amount of bottom leaf defoliation in 3 levels, namely without defoliation (D1), defoliation leaving 3 leaves (D2) and defoliation leaving 2 leaves (D3). The second factor is the ratio of NPK Phonska and guano fertilizer doses in 5 levels, namely NPK Phonska 100% dose (P1), NPK Phonska 75% dose + Guano 25% dose (P2), NPK Phonska 50% dose + Guano 50% dose (P3), NPK Phonska 25% dose + Guano 75% dose (P4) and Guano 100% dose (P5). The results showed that the combination of defoliation treatment leaving 2 leaves under the cob and the application of 7 tons/ha of guano fertilizer without the addition of NPK Phonska was able to increase the weight of the cob without the husk, the length of the cob without the husk and the weight of dry corn kernels per plant. Independently, defoliation leaving 2 leaves was able to increase the weight of dry corn kernels per plot. And the single factor of giving 7 tons/ha of guano fertilizer without the addition of NPK Phonska was able to increase the diameter of the cob without the husk.
