Avaliação da emergência e desenvolvimento inicial do pepino (cucumis sativus L.) em diferentes substratos.

Abstract

In order for planting plants to produce good quality, it is necessary to adapt substrates at the time of planting. That is why it is important to verify the best or best composition that the plant needs for a development, increasing its value and quality. In this sense, the objective of this work was to evaluate the initial development of cucumber (Cucumis sativus L.) in different substrates under greenhouse conditions. The experiment was conducted in the greenhouse of the Laboratory of Ecology and Botany (CDSA / UFCG), in different substrates using the cultivar Cucumber Marketmore 76. The experimental design was completely randomized, with five treatments and four replicates of 25 seeds. The substrates studied were: sand (T1); sheep manure (T2); earth (T3); sand + soil + manure (T4) and sand + soil (T5), where the physiological quality of the seeds was evaluated. According to the results obtained, it was found that the substrates influenced the emergence, the rate of emergence, the seedling length and the dry mass of the seedlings of (Cucumis sativus L.), but the substrate composed of sand + soil + Sheep manure (T4) was considered the most efficient for emergence of seeds, for emergence speed index, seedling length and dry mass of cucumber seedlings (Cucumis sativus L.) providing the best results in all evaluated parameters In this job.
