SERAPAN P DAN PERTUMBUHAN TANAMAN JAGUNG (Zea mays L.) DENGAN PEMBERIAN BEBERAPA JENIS DAN KOMBINASI BAHAN ORGANIK PADA SISTEM IRIGASI TETES

Abstract

The objective of this research ia to know the uptake of P and growth of maize (Zea mays L.) as a result of the application of several types and combinations of organic materials using a drip irrigation system. This research used a randomized block design with 6 treatments and 3 replications: B0 (No Organic Material), B1 (10 tons/ha Manure), B2 (10 tons/ha Biochar), B3 (10 tons/ha Vermicompost), B4 (4.5 tons/ha Biochar + 4.5 tons/ha Vermicompost), B5 (4.5 tons/ha Biochar + 4.5 tons/ha Manure). The research results showed that the combination of organic materials and their combinations had a significant effect on P-Available soil, P-Total soil, Plant Height, Number of Leaves and Leaf Width. The application of organic material had no significant effect on soil pH and P uptake. The best treatment in this study was B1 treatment (10 tons/ha of Manure. The best combination in this study was B5, namely B5 (4.5 tons/ha Biochar + 4.5 tons/ha Manure).
