| Two field experiments were performed during two consecutive summer seasons of 2011 and 2012 at the Private Farm (El- Nagah Village), El-Kassasin region (30o, 11 N, 31 o, 18 E), Ismailia Governorate, to assess the effect of organic manure sources (control, FYM, compost and chicken manure) and potassium humate rates (control, 0.5, 1 and 1.5 g/L) as well as all possible combination between them on growth, yield and its components and chemical constituents of sweet pepper fruits (Capsicum annuum L.) cv. Marconi. Organic manure fertilizers caused significant increases in growth, yield and its components and mineral contents compared with the control treatment (without organic fertilization). Meanwhile, application of chicken manure at rate 10 m3/fed achieved the highest values of all aforementioned parameters followed by the application of compost at the rate of 20 m3/fed and FYM at the same rate, in a descending order. Spraying sweet pepper plants with potassium humate significantly enhanced plant growth, yield and its components as well as NPK content and uptake and total protein in fruits. In this respect, spraying plants with 1.5 g/L potassium humate attained the superiority impacts comparing the other treatments. Hence, it can be concluded that fertilizing pepper plants with chicken manure at rate 10 m3/fed in combined with spraying plants with potassium humate at rate 1.5 g/L gave the highest values of growth, yield and its components and NPK content and uptake as well as total protein content in fruits as compared to other interaction treatments. | ||||
