The influence of organic, bio and mineral ore mixture fertilizers on yield and quality of tomato under North Sinai conditions

الملخص EN

A field study was carried out during summer seasons of 2014 and 2015 at the Experimental Farm of the Faculty of Environmental Agricultural Sciences, El-Arish, Suez Canal University.

It aims to study the effect of organic, bio and a mixture of natural mineral ore fertilizers on the productivity and quality of tomato fruits using local hybrid "Alisa" under sandy soil conditions using drip-irrigation system.

The experiment included nine treatments as follows: T1= 5.7 ton of compost/ fad.

(40 kg N) + 80kg N/ fad., from ammonium sulfate (20.5% N) as control, T2= 11.4 ton of compost/fad.

(80kg N), T3= 17.1 ton of compost/fad.

(120kg N), T4= 11.4 ton of compost/fad.

(80kg N) + 1 ton mixture of natural mineral ore /fad., T5= 17.1 ton of compost/fad.

(120kg N) + 1 ton mixture of natural mineral ore /fad., T6= 11.4 ton of compost/fad.

(80kg N) + 400 g/fad.

nitrogen fixing bacteria containing (NFB) Azotobacter chroococcum, T7= 17.1 ton of compost/fad.

(120kg N) + NFB, T8= 11.4 ton of compost/fad.

(80kg N) + 1 ton/fad.

mixture of natural mineral ore, T9=- 17.1 ton of compost/fad., (120kg N) + 1 ton/fad.

mixture of natural mineral ore + NFB.

Application of 17.1 ton of compost/fad.

(120 kg N/fad.) + one ton/ fad., mixture of natural mineral ore + NFB recorded the highest significant values of total fresh and dry weight, leaf area/ plant, growth attributes, photosynthetic pigments, early and total yield as well as fruit quality
