| Abstract | ||||
| A field experiment was conducted during two successive winter seasons of 2000/2001 and 2001/2002 on onion plant at Wa~y ~I- Moullak, Ismailia Governorate to study the effect of two sources of organic manures on yield production, availability of some micrcnutrients and t~6ir llpta~e b;: ;:'::!r:t. The results revealed that increasing the application rates of urea fertilizer increased the yield production of onion. It was noticed that farmy",rd manure (FYM) resulted in a reduction of onion yield particularly in the firlst season. However, in the second season, yield production of onion wa gradually increased. Application of chicken manure (ChM) at different rates increased the onion yield in both two seasons as compared with farmya{d manure. Results also showed that application of farmyard manure combined with chicken manure at different rates gradually increased the yield. It was concluded that chicken manure combined with farmyard manure may correct the final C/N ratio of the mixture and could create a preferable c9ndition for enhancing the mineralization of the organic-No High percentas,e of yield production were noticed at ratio of (1 :2) (FYM:ChM). The mean values of the yield production can be arranged in the descending order (FY~ .,. ChM) > ChM > urea> FYM. Results also clarified that the effectiveness of the organic materials occurred in the second season than in the first one. Application of farmyard manure, chicken manure and their combination influenc'3d the uptake of Fe, Mn, Zn and Cu by onion plant, and also increased the extractable fraction of the investigated elements particularly at 5 • 10cm depth as compared with other treatments. It was evident that organic fertilizers in all cases improved cropping, with the highest average yiRld of onion, being obtained froill plots receiving farmyard or chicken manur or their combinations. | ||||
