The Yield Gap Maize under Intensive Cropping System in Central Java

The study aimed to estimate the level of yield gaps maize in major producing areas, point out causes farmers’ fields, and identify opportunities existing through management practices production Central Java. This is strategy for closing achieve food self-sufficiency agricultural land. Methods estimates should cover data sources on physical conditions (weather soil), practices, smallholder shapes. relevant methods estimating actual yields (Ya), potential (Yp), water-limited (Yw) were compared. under intensive cropping systems rainfed ecosystems resulted significant differences all cultivation situations. lowland showed Ya, Yp, Yw values 5.57, 12.83, 12.47 ton/ha, respectively. include variety, land preparation, water issues concerned with limited inputs.
