Abstract Intercropping planting system is one of methods to enhance the land productivity. The maize and peanut crops waste has high beneficial to farmers for cattle feed. The study of maize and peanut crops intercropping has been conducted in May-August 2020. Study was arranged by using Randomized Complete Block Design with 5 treatments and replicated for 8 times. Treatments examined were P1: Srikandi Kuning maize variety cultivated by monoculture planting system; P2: Nasa 29 maize variety cultivated by monoculture; P3: Peanut crop cultivated by monoculture; P4: Srikandi Kuning and peanut crop cultivated by intercropping; P5: Nasa 29 and peanut crop cultivated by intercropping. Variables observed were growth and yield components and analysed by analysis of variance and advanced tested by LSD at 5%. To know the land productivity, the calculation of Land Equivalent Ratio (LER) was done meanwhile the Index of Plant Competition (IPC) also was calculated to know the plant competition level. Results showed that the peanut crop productivity by intercropping was decrease about 37.50%-38.79% compared to monoculture. Meanwhile, the productivity of Srikandi Kuning maize variety was also decrease due to the reducing of plant population. The intercropping of Srikandi Kuning and Nasa 29 variety with peanut crop enhance the LER became 1.02 and 1.03. The utilization of Nasa 29 maize variety by intercropping with peanut crop was better than Srikandi Kuning with the lower IPC namely 0.8932 meanwhile the IPC of Srikandi Kuning was 0.9270. The potential waste for cattle feed at maize crop plantation by monoculture was higher than intercropping with peanut crop and peanut crops by monoculture namely P3: 572 head/ha; P1: 500 head/ha; P5: 484 head/ha; P4: 454 head/day; P3: 288 head/day.
