Description
This study aimed to evaluate the influence of nitrogen fertilizer concentration and type on the growth and production of spinach (Spinacia oleracea L.) cultivated in protected environments (greenhouses). The scheme of the experiment was that of split plots. Nitrogen dose is considered the main factor in the scheme (3 main plots, respectively 60, 80, and 120 kg N Ha-1), while in the secondary plots, different forms of commercial nitrogen fertilizers (ammonium nitrate and urea) are considered, which are applied in quantities that provide the same planned amount of nitrogen. The collected data were biometric (individual weight of plants, dry weight of above-ground mass, number of leaves, leaf surface) and quantitative (harvest production for each experimental unit). Regarding the results, variant C2 (11.029 kg/var) had the best yield compared to other variants, and the B1 variant (7.460 kg/var) had the lowest yield compared to other variants. The average weight of spinach plants is higher in plants of variant C2 (78.714 g/plant) compared to other variants, while there were no significant differences in other variants. The number of leaves and the surface of the leaves did not have any significant differences between the variants. As for the dry matter content, variants A1, A2, and C2 had significant differences compared to variants B1, B2, and C1.
