Avaliação de substratos na produção de mudas de pimentão irrigadas com diferentes qualidades de água.

Abstract

The present work aimed to evaluate the production of sweet pepper seedlings, Capsicum annuum L., when submitted to different organic substrates and irrigation with different water qualities. For this purpose, Yolo wonder peppers (FeltrinR seeds) were sown in plastic cups and distributed in a completely randomized experimental design in a 5 x 3 factorial scheme with 5 replications, totaling 75 experimental units. The substrates consisted of the following compositions: S1 = soil, S2 = soil + organic compost, S3 = soil + poultry manure, S4 = soil + humus and S5 = soil + goat manure, and three water qualities: A1 = water well, A2 = gray water and A3 = supply water. The analyzed variables were plant height, root length, number of leaves, leaf area, stem diameter, green and dry mass of shoot and root of pepper seedlings. It was verified that the different qualities of irrigation water can be used without compromising the quality of the seedling. The soil substrate plus poultry litter associated with well water is recommended for the production of pepper seedlings, as it provided the results.
