Desenvolvimento de plantas jovens de pimenta-de-cheiro (capsicum chinense) fertirrigada com diferentes soluções nutritivas

Abstract

The production of quality seedlings is the most important stage of the horticultural sector, for it is from it that will give all follow-up the production of wholesome and viable plants. This work was developed with the objective of evaluating the development of young plants of habanero pepper (Capsicum chinense) fertirrigated with different nutrient solutions, in substrate of coconut fiber and vermiculites. The experiment was conducted in a vegetation house in the Institute of Education, Agriculture and Environment of the Federal University of Amazonas, in the campus of Humaitá-AM. The completely randomized design was used with 4 treatments and 28 replications, with a total of 112 sample units, with 0%, 50%, 75% and 100% of the recommended nutrient solution dose for bell pepper reference. The following development parameters were evaluated: number of developed leaves, neck diameter, main root length, plant height, fresh root mass, fresh aerial part mass, root dry mass and aerial part dry mass. Therefore, the decision for the dosage of the nutrient solution for the production of young plants of habanero peppers (Capsicum chinense) should be made according to the desirable characteristics. The dosage between 71% and 73% is recommended to obtain better characteristics of plant height, leaf number and collar diameter, while 91% to 98% of the recommended dosage is ideal for the production of dry and fresh mass.
