Abstract | ||||
The effect of three organic fertilizers; viz, chicken manure (ChM, 20 and 40 m3 fed.-1), pressed olive cake (POC, 20 and 40 m3 fed.-1) and cow manure (CwM, 30 and 60 m3 fed.-1) on growth and productivity of cowpea under water stress condition was investigated. A field experiment was carried out at The Experimental Farm, Fac. Environ. Agric. Sci., Arish Univ., El-Arish, Egypt in summer seasons of 2013 and 2014 in a sandy soil. Irrigation water requirements (IWR) were 50% (1050 m3 fed.-1) and 100% (2100 m3 fed.-1) of the estimated crop evapotranspiration. Results showed that20 m3 fed.-1of both ChM and POC were more effective for most vegetative growth parameters and yield components in well irrigated-cowpea in both seasons. Water stressed-cowpeas fertilized by 60 m3 fed.-1 of CwM showed the lowest reduction in yield (34.07 and 29.86%) in both seasons, respectively, followed by POC fertilizer at 40 m3 fed.-1. Water stressed cowpeas fertilized by 40 m3 fed.-1 of POC gave the highest values of water use efficiency (0.86 and 0.87 kg m-3). The lowest total consumed water was recorded with 20 and 40 m3 fed.-1 of ChM–fertilized plants under normal and drought conditions. The content of biochemical compounds and macro-elements as well as measurements of some important tissues in leaflet of 3rd leaf related to drought and organic fertilizers were also studied. It was concluded that application of 20 m3fed.-1 of ChM gave the highest yield in well irrigated-cowpea. Doubled amount of organic fertilizers reduced the deleterious effect of drought especially POC and CwM by saving irrigation water. | ||||
