Abstract:
A field expenment was conducted for two consecutive season) 2009-2010 (and 2010/2011 (in aprivate farm at El-Riyadh area-Suda Arabia) Latitude 38 24 N Longitude 43 64 E and altitude 600 rocters above sea level, to investigate the effect of chicken mame and we application on growth and yield of wheat Triticum aestivum L. Plant cv Yocora Rojo The organic and inorganic fertilizers were added single or in combination Organic fertilizer uwd in this study was chicken manure at) 10 ton/ha (with different ratios) 100% 75%, 50 %and 25 (or two seasons oorganic fertilizers used were Urea) 46%N (at level 300ку Niha. Triple super phosphate) 48 %P205 (at level 175kgha and potassium sulphate at level 50kg K20-ha
The uratments were arranged in completely randomized block design with four replicuiom The growth parameters measured were plant height, number of leaves and plant dry weight Nitrogen uptake by plant narugen use efficiency and agronomic efficiency were also studied in this experime
The results showed that organic, inorganic fertilization and their combinatio significantly mcreased all growth purameters measured in this study. On the other hand there is msignificant difference between single addition of chicken mamav its cumbination of 50 with urea and unca akne on growth parameters While s application of other different ratios with unca had significant effect
The results showed that the moutments exerted significant increuse in the percentage of nitrogen in the seeds in comparison with the control Also the increase in the pescentage of nitrogen was significant with the addition of combination of organic mature and chemical fertilizers in comparison with ures alone While there is insignificant mcrease in compuerson with urea fertilizer in the
second sewwon although there increasing in the percentage of retrogen in the seeds With regards to the perormage of nitrogen in the leaves, the treatments exerted a significant increase compared to the control in the two season Also chicken manime in combinatson with inorganic fertilizers caned a significant increase in the percentage of nitrogen in the leaves as compared with ures alone in the two
The results indicated that the sitrogen uptake by plants incerased significantly with all treatmens compared with control in the two seasots. Also the contina of chicken manure with urea increased the uptake significantly in comparison with reo fertilizer,
The results revealed that the value of nitrogen use efficiency ranged between 14.15-34-3 and 26.68-35.34 in the first anil second seasm mspectively With regard to agronomic efficiency it ranged from 109 21.27 and 11.93-2612 m Use first and second seasons wspectively
