ABSTRACT
The productivity of dryland farming volatile and relatively low, it is because the productive agricultural land continues to degrade due to mis management. To that end, the need for innovation in soil fertility management easier and cheaper for dryland farmers in degraded lands. Such innovation is through the fallow system with legume cover crop a season. Innovation fallow system with legume cover crop a season is possible to do by dryland farmers because it has the potential to restore soil quality and land productivity in a short time through increased soil organic carbon stock. This study aimed to determine the effect of the innovation fallow system with legume cover crop a season to the improvement of soil properties and corn yields in degraded soils. Research in design Randomized Completely with 6 types of treatment, namely: (1) land left open (without LCC a season) or practice farmers; (2) fallow with Phaseolus lunatus (Pl); (3) fallow with Mucuna pruriens (Mp); (4) fallow with Calopogonium monocoides (Cm); (5) fallow with Crotolaria juncea (Cj) and (6) fallow with Cajanus cajan (Cc). The results showed that the innovation fallow system with LCC significantly capable of restoring the fertility of degraded physical soil, namely the use of LCC type Crotolaria juncea, Mucuna pruriens and Phaseolus lunatus as fallow crops, improving real C-organic content of 1.57% to 2.21-2.25% > of the type Cayanus cajan and Calopogonium monocoides and lower clay content from 72.47% to 70.2-70.37% clay, as well as improving total pore, Aeration pore and water available pore in the soil. Using LCC type Crotolaria juncea, Mucuna pruriens and Phaseolus lunatus markedly increase the average yield of corn karnels of 1.56 times > of the control treatment, which only reached 2.27 t ha-1 corn karnels.
