The experiment was conducted in Agriculture research station Deportment of Horticulture and landscape / Agriculture college / Tikrit University, in Agriculture season 2018, as Factorial experiment according to split plot system by complete Randomized Block design (RCBD) with three replicates, to study effect of three types of organic nutrient’s included (Nido-P , Root plex

Iron and phos-pro calcum) in addition to the control treatment on characteristics of fruit yield and seed for four varieties of muck melon (local , Ananas , Hales best jumbo and melon Ananas).
The results showed that Hales best jumbo variety gave significant improving in fruit number and yield characteristics which were 2.24 fruit. Plant -1 and 22508 Ton .ha-1 respectively compared to another varieties while Melon Ananas showed significant improving in fruit diameter, fruit weight 100 seed weight, and one seed weight 12.94 cm. Plant-1 ,1.186 g .plant-1 3.890 g . Plant-1 and 0.035g . Plant-1 respectively compared with local and Hales best jumbo varieties. Whereas local variety recorded significant improving in seed weight and total yield characteristics 16.44 g . Plant-1 and 164,400 Kg.ha-1 respectively compared with Hales best jumbo. the results also showed that phos-procalcun nutrition gave highest fruits numbers and total yield of fruit compared to control treatment and root plex Iron nutrition gave highest seed weight and total yield compared to Nido-p nutrition while Nido-p gave highest 100 seed weight and one seed weight characteristics compared to another nutrient’s . The interaction between Hales best jumbo variety and phos-procalcun nutrition showed significant improving in numbers and total yield of fruit. While the interaction between melon Ananas variety and control treatment gave significant improving in fruit length, whereas, the interaction between melon Ananas variety and root plex iron nutrition showed significant in fruit weight, but the interaction between local variety and control treatment gave significant improving in seed weight and total yield characteristics ,finally the interaction between melon Ananas variety and Nido-P gave significant improving in one seed weight and 100 seed weight characteristics.
