Abstract

Culture environments, trays and doses of organic compost were evaluated in the formation of cucumber seedlings (Cucumis sativus L.). Five environmental conditions were tested: (A1) a greenhouse with height of 2.5 m, covered with polyethylene film, (A2) nursery with height of 2.5 m, monofilament fabric, 50% shading, (A3) nursery with height of 2.5 m, heat-reflective screen, 50% shading, (A4) nursery with a height of 1.8 m, covered with coconut tree straw and (A5) greenhouse with height of 4.0 m, covered with polyethylene film, with zenith opening and thermo-reflective cloth under the plastic. Trays of 72 (R1) and 128 (R2) cells were filled with 93% soil and 7% organic compound (S1), 86% soil and 14% organic compound (S2) and 79% soil and 21% organic compound (S3). It was used a randomized design in split-split-plot scheme, with five replicates (environments x trays x substrates). The greenhouses provide the best environments for the formation of cucumber seedlings. A tray of 72 cells is the best container, promoting more vigorous seedlings in substrate with soil and 7 or 14% organic compound.

Highlights

The cucurbitaceae contribute with approximately 25% of vegetables sold in Brazil
This study aimed to evaluate environmental conditions, polystyrene trays and substrates with organic compost in the formation of cucumber seedlings at Aquidauana region, in the state of Mato Grosso do Sul
In the nursery (A2 and A3), the containers were similar for all parameters evaluated, except for plant height in the nursery with aluminized cloth (A3), which was higher in the tray with 72 cells (R2) (Table 2)

Summary

Introduction

The cucurbitaceae contribute with approximately 25% of vegetables sold in Brazil. The cucumber features importance, as it is consumed raw, tanned in brine, and rarely mature (CAÑIZARES et al, 2002). In the upper South Pantanal of Mato Grosso and in the state itself, vegetable production is low and supply is conducted by the offer coming from other Brazilian states. Substrate with Organosuper® for cucumber seedlings formation in protected environments and polystyrene trays. The seedling has an important question in production systems, where the standard quality is crucial to the future performance of the plant field. Factors such as substrates, containers and crop environments are techniques that seek to maximize the productive potential and vigor of seedlings to be transplanted to the field
