| Abstract | ||
| Afield study was carried out during fall season 2016, in vegetable field in Horticulture Department Horticulture, Agriculture College-University of Baghdad (Abu Ghraib). In order to study the effect of the application poultry manure and humic acid in growth and yield of two cultivars of lettuce (Lactuca sativa L.). The study included two factors: the first factor is the cultivars, Local and Foreign cultivar (Polaris), and second factor which included 12 treatments. That is Control treatment fertilizing by recommended chemical fertilizer, 10 g plant-1 poultry manure, 20 g plant-1 poultry manure, 40 g plant-1 poultry manure, 1.5 ml L-1 humic acid, 3 ml L-1 humic acid, 10 g plant-1 poultry manure + 1.5 ml L-1 humic acid, 20 g plant-1 poultry manure + 1.5 ml L-1 humic acid, 40 g plant-1 poultry manure + 1.5 ml l-1 humic acid, 10 g plant-1 poultry manure + 3 ml L-1 humic acid, 20 g plant-1 poultry manure +3 ml L-1 humic acid and 40 g plant-1 poultry manure +3 ml L-1 humic acid. The experiment factorial (2×12) and three blokes the treatments were randomly distributed according to (R.C.B.D) and means according to L.S.D (P>0.05) and the important results were summarized as following: The application at poultry manure and humic acid led to superior produced cultivar over local cultivar for all studied traits, treatment T12 by giving highest average of leaf area, number of leaves, leaf content of chlorophyll, leaf content of nitrate, percentage of head folding, mean of total head weight and total yield recorded 1202 cm2, 51.278 leaf plant-1, 58.57spad, 88.58%, 1.771 kg and 118.61 ton h-1 respectively, Concludes this is manures characterize given results positive in vegetative growth and contain leaves from nutrient elements and yield mount. | ||
