| ABSTRACT : This experiments was carried out in agricultural field in Alamadiya location about 23 Km south of Hillah city, during the spring seasons 2012 to study the effect intercropping and organic-mineral fertilization on growth and production potato and sweet corn, according to split plot withen randomized complete block design, with three replicates. The experiment included planting two potato cultivars (Desiree & Aladdin) under monoculture and intercropping system with sweet corn within eight treatments of organic-mineral fertilization per donum (without fertilization ,5 m3 sheep manure,5 m3 poultry manure, 150 kg NPK, 5 m3 sheep manure + 150 kg NPK, 5 m3 poultry manure +150 kg NPK, 2.5 m3 sheep manure +2.5 m3 poultry manure and 2.5 m3 sheep manure + 2.5 m3 poultry manure + 150 kg NPK. The results showed outstanding Aladdin cultivar in the quality characteristics as dry weight, starch & protein ratio, tuber content from NPK elements and the yield characteristics as number and weight tubers for marketing, the marketing yield compared desiree cultivar. The agriculture type had significant effect in the characteristics above, monoculture had outstanding in quality and quantity yield characteristics compared with the intercropping. while the intercropping showed higher rate of the suitable tubers for marketing. The organic – mineral fertilization application showed significant increasing in characteristics of quality and quantity yield compared with non fertilization treatment and there is difference in the effect by differences type and level the fertilization. The triple interactions of factors had significant effects in quality and quantity yield characteristics. Organic-mineral fertilizer, monoculture and Aladdin cultivars had significant outstanding in most of studied characteristics, where treatment of 5 m3 poultry manure & monoculture & Aladdin cultivar showed the higher rate for the marketing yield that reach 40.5 ton/ hectare. | ||
