Produção de mudas de pimentão em substratos alternativos

Abstract

In pepper cultivation, alternative substrates are used in order to provide conditions for adequate plant development. The objective was to evaluate the initial development of pepper seedlings on alternative substrates. The trial was carried out at the Federal Institute of Piauí – Campus Uruçuí, using a specific randomized design with five treatments and five replications, employing one cv. Yolo wonderful. The treatments consisted of the following substrates: commercial Basaplant (T1); 50% coconut wood + 50% bovine ester (T2); 50% coconut wood + 50% goat ester (T3); 50% carbonized rice husk + 50% cattle manure (T4); 50% carbonized rice husk + 50% goat manure (T5), normally the height of the aerial part, diameter of the collar, number of leaves, fresh mass of the aerial part and roots and dry mass of the aerial part and roots. The data were subjected to analysis of variance and the means were compared using the Tukey test, at 1% probability. Treatments T4 and T5 had the highest heights and dry mass of shoots, while T3 had the highest number of leaves. T4 allowed greater fresh mass of shoots, fresh mass of roots and dry mass of roots. The largest diameter was observed in plants grown in T3, T4 and T5. Alternative substrates composed of 50% carbonized rice husk + 50% cattle manure and 50% carbonized rice husk + 50% goat manure provide better initial development of pepper cv seedlings. Yolo wonderful
