| Abstract | ||
| An experiment was carried out during spring season 2012 in experimental field-Al-Raaba station/ Horticulture Department - Ministry of Agriculture. The aim of this experiment to study the effect of Mycorrhiza (Glomus moassea), Biochar, mulching under three levels of chemical fertilization on yield and quality of tomato fruits (Ascorbic acid, titrable acidity and dry matter). Experiment designed in split-split plot design in three Replicates, when chemical fertilization represented mean factor treatment which added in three levels (0, 50, 100) of recommended fertilization and sign as (S0,S1,S2) to represent it respectively ,nitrogen added as urea in 200 kg.h-1, phosphor added as rock phosphate in 60 kg.h-1 and potassium add as potassium sulfates in 120 kg.h-1. Mycorrhiza added in two treatments as control and at rate of 100gm (mixture soil, root and spore) per plant and characterize as (B0, B1) to represent it respectively, mulching and Biochar were the sub–treatment, mulching added as control and 9 cm thickness layers sign as (M0, M1) to represent it respectively. Biochar treatments added as control and at rate 5 ton /h which characterize as (C0,C1) to represent it respectively, the experiment was irrigated under drip irrigation. The results showed that all study factors increased significantly the dry matter, ascorbic acid and titrable acidity in tomato fruit, the interaction treatments S2B1M1C1 recorded the higher dry mater value in fruit was 10.64%, with no significant differences with S1B1M1C1 treatment was 10.08%. The interaction treatment S2B0M0C1 recorded the higher titrable acidity value in fruit was 0.857%, and the higher value for ascorbic acid S1B1M1C1 treatment was 36.17mg.100-1 juice. All study factors increased significantly the early yield and total yield, the interaction treatments S1B1M1C1 recorded higher values (44.87, 9.54) ton.h-1 for total and early yield respectively, the rustles show that interaction among experiment factors decrease amount of chemical fertilizer to 50% in S1B1M1C1 treatment. | ||
