| Abstract | ||||
| INFLUENCE of humic, fulvic acid and calcium foliar application on growth, yield and quality of tomato (H9663 hybrid) was investigated during 2013 and 2014 summer seasons. The experiment was designed in completely randomized block at the Experimental Station, Faculty of Agriculture, Cairo University, Giza, Egypt. Solutions of humic acid (0.4 %), fulvic acid (4%) and chelated calcium (0.25 %) were applied as foliar sprays alone or in combinations on tomato plants at four times after two, four, six and eight weeks from transplanting. Vegetative growth parameters and nutrients content (N, P, K and Ca) of tomato plants as well as yield, fruits quality and incidence percentage of blossom end rot in fruits were investigated on treated and untreated plants. Results indicated that the foliar application of humic, fulvic acid and calcium either individual or in combinations increased vegetative growth, yield, fruit quality and decreased the incidence of blossom end rot in tomato fruits. | ||||
