GROWTH AND PRODUCTION OF CORN COMPOSITE (ZEA MAYS L.) UNDER APPLICATION OF BOKASHI KALAKAI FORMULATION AND P FERTILIZER ON INTERNAL PEATLAND

Abstract

The purpose of this study was to determine the formulation of bokashi kalakai and P fertilizer on the growth and yield of composite maize (Zea mays L.) on inland peatlands. The study used a non-factorial randomized block design (RAK) with 5 treatment levels, namely, F1 = No Treatment. , F2= Bokashi Kalakai (15 〖t ha〗^(-1)), F3 = Bokashi Kalakai (15 〖t ha〗^(-1)) + P (150 kg〖 ha〗^(-1)), F4 = Bokashi Kalakai (15 〖t ha〗^(-1)) + P (300 kg〖 ha〗^(-1)), F5 = Bokashi Kalakai (15 〖t ha〗^(-1)) + P (450 kg〖 ha〗^(-1)). The results showed that the application of bokashi kalakai and P fertilizer on inland peatlands affected the growth and yield of composite maize. Kalakai bokashi treatment 15 ton ha-1 + fertilizer P 450 kg ha-1 on inland peatland had a significant effect on plant growth of plant height by 201.11 (8 WAP), number of leaves 14.65 strands (8 WAP), leaf area 4295.99 g, total plant dry weight 147.27 g, seed weight/ plant 185.41 g, weight of 100 seeds 30.85 g, weight of cob cobs 259.32 g, weight of cob without hulls 232.67 g, plant growth rate 7.5 (6-8 WAP), leaf area index 2.84 (8 WAP), the yield of harvested plots was 1107.62 g and the yield of dry shelled corn was 3.12 tons ha-1.
