Comparison the Effect of an Organic Nutrient (Nektafol) Under Production and Open Field Condition on the Growth and Yield of Lettuce

Abstract

The Horticulture Department & Landscape Design/College of Agriculture at the University of Mosul conducted the study in two cultivation systems (unheated plastic house and open field) connected to the fields to examine the effects of using the liquid nutrient (Nektafol) at concentrations (0,2,4,6 mlL-1) on the vegetative growth characteristics, quantitative and qualitative yield of plants of lettuce (Quantum variety). Three replications of the experiment were used, and the averages were compared using Duncan’s multiple range test at the 5% level of probability. The experiment was conducted utilizing split. Plot. System. with R.C.B.D. Design. The characteristics of vegetative development and the quantitative and qualitative yield can be summed up as follows: When compared to plants grown under plastic house, plants that were grown in a field in the open. were significantly better in most of the studied characteristics. It was found that using the liquid nutrient Nektafol at two concentrations of 4 and 6ml L-1 significantly improved the qualities of vegetative growth and the total yield of heads of lettuce, as well as the qualities under open field and plastic house.
