A portable hand-held device to inject liquid urea solution was designed, built and tested on conventional wheat straw bales. The effects of types of injector, injection pressures and modes of injection on wetted area i.e. liquid distribution pattern and liquid retaining efficiency of baled straw were studied. The liquid was injected at different injection pressures of 1.0, 2.5, 4.0 and 5.5 kg/cm in central horizontal (M ) and eccentric horizontal (M ) modes of injection at predetermined five number Of injecting stations using single orifice flat fan (N ), two-transverse orifice (N ) and triple orifice (N3) injectors. The injector N was1found best in terms of maximum values of wetted area (55.90%) and liquid retaining efficiency (66.60%) at4 kg/cm2 injection pressure in M mode of injection followed by Nand N injectors. Doubling the number of injecting2stations to ten had appreciably irtereased the liquid retaining efficiency and moisture content of ammonia (urea) treated baled straw.
