Abstract
The compatibility between plant growth and ratio of nutrient adequacy in soil is very important in growth and production corn crops. This study aims to determine of various NPK fertilizer ratios on the stages of growth in corn plants. This research was conducted in September – January 2022 in Patemon Village, Pakusari.The experiment was designed with a non-factorial randomized group design (RAK) consisting of 9 treatments including: (N 48 kg/ha, P2O5 48 kg/ha, K2O 48 kg/ha), (N 77 kg/ha, P2O5 68 kg/ha, K2O 107 kg/ha), (N 66 kg/ha, P2O5 68 kg/ha, K2O 84.5 kg/ha), (N 77kg/ha, P2O5 86 kg/ha, K2O 107 kg/ha), (N 66 kg/ha, P2O5 86 kg/ha, K2O 84.5 kg/ha), (N 100 kg/ha, P2O5 68 kg/ha, K2O 108 kg/ha), (N 89 kg/ha, P2O5 68 kg/ha, K2O 85 kg/ha), (N 100kg/ha, P2O5 86 kg/ha, K2O 108 kg/ha) and (N 89 kg/ha, P2O5 86 kg/ha, K2O 85 kg/ha). Fertilization treatment N 77 kg/ha, P2O5 68 kg/ha, K2O 107 kg/ha had a significant effect on weight cobs with kelobot (289.67 g), weight cobs without kelobot (256.78 g), cob diameter (4.77 cm), cob length (20.17 cm), dry seed weight (195.89 g), but insignificant effect on vegetative phase observation variables. The results showed phosphorus and potassium nutrients had positive correlation in generative phase. This nutrients will affect production in photosynthetes distributed to cobs. So potential for dry flat yields was obtained in fertilization treatment N 77 kg / ha, P2O5 68 kg / ha, K2O 107 kg / ha of 13.99 tons / ha.
