| Abstract | ||
| ABSRRACT: The experiments was carried out in agricultural field in Alamadiya location about 23 Km south of Hillah city, during the spring seasons 2013 to study the effect intercropping within two density 30& 60 cm and organic-mineral fertilization on growth and production sweet corn, according to randomized complete block design, split plot with three replicates. The experiment contained two factors, main plots involve sweet corn monoculture and sweet corn intercropping within two distances intercropping 30 & 60cm, sub plots involve twelve treatments of organic-mineral fertilization every donum {without fertilization ,5 m3 sheep manure, 5 m3 sheep manure + 75 kg, 5 m3 sheep manure + 150 kg , 5 m3 poultry manure, 5 m3 poultry manure +150 kg NPK, 5 m3 poultry manure +150 kg NPK, 2.5 m3 sheep manure +2.5 m3 poultry manure, 2.5 m3 sheep manure + 2.5 m3 poultry manure + 150 kg NPK, 75 kg NPK and 150 kg NPK. Results were obtained: The results explained outstanding monoculture in almost vegetative growth indicators and the yield characteristics compared with the intercropping, while intercropping outstanding in the quality yield characteristics. Add the organic-mineral led to significant increasing in all the studied characteristics compared with control treatment. The dual interaction among the studied factors showed significant impact for the studied characteristics. organic- mineral fertilization and monoculture showed the higher rate to the vegetative growth indicators and the yield, while 2.5 m3 sheep + 2.5 m3 poultry manure +75 kg NPK gave 6.8 ton/ hectare. While organic- mineral fertilization and intercropping appeared higher value vitamin C, saccharine, protein and 100 seeds weight. | ||
