Abstract

The objective of this study was to evaluate the production of calla lily in an NFT system. The experiment was carried out in a greenhouse, using a 2 x 2 factorial scheme in a completely randomized design (CRD), with fifteen replications. The treatments were a combination of two hydroponic profiles (100 and 150 mm of height) and two nutrient solutions. Calla lily plantlets obtained from rhizome buds in trays containing nutrient solution, were transferred to a laminar flow of nutrients, and the experiment lasted 12 months. The height of stems and inflorescences were evaluated, as well as the length and diameter of the inflorescence, the number of flowers per plant and number of flowers per m2 . Growing calla lily plants in an NFT system is feasible. The nutrient solution with the highest concentration of nutrients, particularly N and K, and the profile of 150 mm, are the most suitable for the production of calla lily as a cut flower in a laminar flow of nutrients.

Highlights

Floriculture is characterized as one of the most promising segments of the Brazilian agribusiness
The treatments consisted of a combination of two hydroponic profiles (100 and 150 mm of height) and two nutrient solutions (A and B) and (Table 1), totaling four treatments, with 15 replicates
Nutrient solutions and hydroponic profiles affected the height of stems and inflorescence, inflorescence length and diameter (p ≤ 0.05)

Summary

Introduction

Floriculture is characterized as one of the most promising segments of the Brazilian agribusiness. One of the major problems in the soil cultivation of calla lily is the high incidence of diseases, especially soft rot, caused by the bacterium Pectobacterium carotovorum, infecting the rhizome and the plant stem base, making the tissues soft and moist, which can compromise the whole cultivation area. In this context, the nutrient film technique, or NFT system, is a viable alternative for growing calla lily, as it avoids plant exposure to soil bacteria, significantly reducing the incidence of diseases, the need for spraying with pesticides, and providing best quality flowers (CHANG et al, 2013)
