Two field experiments were conducted on bell pepper (Capsicum annuumL.) variety of " California wonder" plants during the summer seasons of 2012 and 2013 at EL-Baramon experimental farm near EL-Mansoura, Dakahlia Governorate Egypt to study the effect of -planting treatments as well as their interactions on growth and productivity of bell pepper. Fifteen treatments were arranged in split plots design, which were the simple possible combination between three treatments of soil application (Straw rice costs (4 ton/fed.), Humic acid (5 kg/fed.), and Polymers (20 kg/fed)) and five foliar treatments of ( (tap water), Ca (calcium citrate 2.5 mg/L) + B (boric acid 1.5 mg/L), Yeast (10 mg/L) + K (potassium citrate 2.5 mg/L), Yeast (10 mg/L) + NAA (naphthalene acetic acid 2.5 mg/L) + K (potassium citrate 4 mg/L) and Zn (0.35 gm/100 L) + Cu (0.20 gm/100 L) + Mn (0.25 gm/100 L) in sulphure form). Each treatment was replicated three times. Thus, the total numbers of plots were 45 plots plus control treatment. The NPK fertilizers were added to soil cultivated with pepper plants as recommended by the Ministry of Agriculture and Soil Reclamation. The seedlings of bell pepper (Capsicum annuum L.) were transplanted on 1st of April in 2012 and 2013, respectively, on two side of ridges at 30 cm a part.
Plant height, fresh weight, dry weight, leaf area, number of leaves, number of flowers and number of branches were measured as vegetative growth parameters. Yield and its components as number of fruits, fruit weight g/plant, earl and total yield (ton/fed.). as for fruit quality Chlorophylls (a, b and total chlorophyll), NO2-N (mg/kg), Vitamin C (mg/100g), Acidity %, Total carbohydrate (%), Xanthophyll and carotene (mg/100g), TSS % reduce sugar, non-reduce sugar and total sugar %.. The highest values of all parameters were recorded with spray Y+NAA+K with adding humic acid at 5 kg/fed. From that result it can concluded that the treatment of adding 5 kg/fed. humic acid with spray Y+NAA+K followed by the spray treatment of Zn+Cu+Mn under the same soil application considered the best combination and it is recommended for pepper plant grown under similar field conditions.
