EFFECT OF PLANTING DENSITY AND SUBSTRATE TYPE OF THE CHARACTERISTICS OF THE GROWTH, THE ONION SEEDLINGS, BE PREPARED IN MODULE WITH MORE NEST

The experiment was conducted in QTTB Korca. The objective of the study was to assess the impact of the number of seedlings in the nest and the type of substrate in the onion seedlings indicators prepared in many cube trays. For the sowing, were used the seeds cv. “Tak Star”. In the study, three types of substrates were tested and five seedling density in the nest. Planting the seeds was conducted in polystyrol trays containing 288 nests. In each nest were planted 1, 2, 3, 4 and 5 seeds, respectively, werepreparerd the same numberof so seedlings for nest. The experiment was set up with three repetitions according to the randomized block scheme with under separate variants. Types of substrate used, constituted the main version and the number of plants in the nest, sub-alternatives. Because of the competition, during the preparation of seedlings was evidenced a reduction in the number of leaves, height of seedlings, their diameter and dry matterNo differences recorded in connection with the substrates used. With better indicator seedlings are prepared to submit variant with three seedlings per cell density.
