The utilization of stored soil moistures for forage legumes supply in the dry season in west Timor,Indonesia
(0) Subsistence cattle production and maize cultivation are the main agricultural activities of farmer in West Timor, Indonesia.Maize yields tend to be low and inconsistent due to low agricultural input levels,poor crop nutrition and management and climate variability.Whilst the average annual rainfall (which falls between December and April) is 1500 mm per annum,it is highly variable and uneven in its distribution.During the dry season ( April‐November) fodder supply becomes increasingly difficult to source and of a lower quality as the dry season progresses resulting in a decline in animal liveweight.Maize as a staple food is grown without inorganic fertilizer inputs with production risk usually addressed through the growing of larger areas in preference to investment in intensive cultivation and costly fertilisers.However,pressure on land resources is increasing and the soil fertility status is declining which is forcing farmer to practice shifting cultivation to maintain production.Relay cropping of high‐biomass forage legumes during the late wet season ( February sowing ),when water and nutrient requirement by maize is declining,has potential to supply quality forage for livestock production and to improve soil nutrient availability through mineralization for the following maize crop.
