The effect of biological fertilizer formulation on the growth and harvest yield of several corn (Zea

Dry land is land whose water source depends on rainfall. The research location is in Singosari, which is considered dry land because it lacks a water source for irrigation. The purpose of this study was to determine the effect of varieties and formulations of biofertilizers on the growth and yield of corn plants, as well as to identify the interaction between different varieties and biofertilizer formulations on the growth and yield of corn plants. This research was conducted in Pakel Hamlet, Baturetno Village, Singosari District, with a land area of 1000 m2. The implementation time of this research started from March 2024 to July 2024. This study used a Split Plot Design with the main plot being corn varieties (V) and subplots being the doses of granular and liquid biofertilizers (D). The combination of various treatments with the type of biofertilizer formulation showed significant interactions with several variables. Overall, the granular biofertilizer formulation showed higher results compared to the liquid formulation. The Pertiwi 6 variety tends to produce higher average yield variables compared to other varieties.
