Abstract
Two field experiments (the first one started on 3/11/2010 and the second was on 3/1/2011) were carried out to investigate the. yield and quality of spinach as influenced by organic ( two levels: 0.0 and 15 m3 compost fed-1), Bio. ( 0.0 , Microbine and Nitrobine ) and chemical fertilization ( Four levels; 0.0 , 50.0 , 100.0 and 150 % of recommended dose) at EL-Gawashna village, EL- Sharkia Governorate, Egypt. The possible combination between the studied factors levels represented 24 treatments The obtained results can be summarized in
Increasing mineral fertilizations from 0 – 50% led to a progressive increase in yield weight amounted by 20.649 % , while rising mineral fertilizations from 50.0 –100% led to a slight increase in that trait (0.856 %). 3.651 % increase in yield weight was noticed due to inoculation with both nitrobine and microbine.
Using organic fertilization decreased plant nitrate by 14 %. Spinach plant nitrate was decreased from 279.087 to 241.700 ppm as a result of Nitrobine fertilization and from 279.087 to 241.977 ppm as a result of microbine fertilization.
Increasing in spinach plant spinach nitrate was found concomitant with a constant increase in NPK mineral fertilization dose.
spinach plant nitrite was statistically responded to both compost application and bio- fertilization where statistically decreased in it's value compared with unfertilized treatment.
Organic fertilization tended to increase N content of spinach plant under any studied mineral fertilization level ( 50, 100 and 150 % of recommended dose)
Inoculation of spinach seeds before planting by nitrobine and microbine increased N content of spinach plant by 5 % and 5%, respectively.
No evidence for superiority of any inoculation than the other regarding to increasing the nitrogen content of spinach plant.
Compost effects did not appear on P content of spinach plant, whenever N P K fertilization have done .
Inoculation maximized phosphorus content of spinach plant where neither organic nor NPK mineral fertilization were added than that under another conditions .
No difference in Phosphorus content between nitrobine and microbine treatment means was found .
8- Phosphorus concentration was significantly increased with increasing N P K fertilization level till 100 % then decreased after that (150 % of N P K ) .
A slightly increase was found in K content due to both organic fertilizer and bio – fertilizer addition compared with no addition of each .
