1. SHADING AS A DETERMINANT FACTOR FOR THE SURVIVAL AND GROWTH OF Cabralea canjerana IN SOUTHERN BRAZIL
ABSTRACT Plantations with native tree species, which emphasize biodiversity conservation, may not succeed because of a lack of forestry knowledge about the native species. Cabralea canjerana is an important tree species, which is rarely present in area restoration programs because of the difficulty in establishing it in plantations. Despite this, the species

2. Erratum
Abstract Bauxite mining has been carried out around Poços de Caldas, Minas Gerais, since the 1940s. Companies operating in the region pioneered land rehabilitation in Brazil, conducted since the early 1980s. Different procedures of recontouring, runoff drainage, soil preparation and vegetation planting were employed. This research aims to evaluate current e

4. Foliar application of molybdenum on cover crops and response of common beans in successive cultivation
ABSTRACT The effects of foliar application of Mo and use of N from cover crops (Crotalaria juncea L. and Canavalia ensiformis (L.) DC) on the performance of common beans were investigated in this study. Field experiments were carried out in a succession planting system (cover crops - common beans), and nitrate reductase activities were evaluated in the labor

5. Scheduling optimum planting window for gladiola based on El Niño Southern Oscillation
ABSTRACT: Gladiola is an important cut flower worldwide and scheduling field gladiola production is largely dependent on planting at the correct time since its development is controlled by the air temperature. The aim of this study was to configure a planting window of gladiola in order to harvest spikes to be sold on All Souls' Day and Mother's Day holidays

6. Field performance of hermaphrodite papaya plants obtained through molecular selection and micropropagation
Abstract Most commercial papaya varieties segregate hermaphrodite and female plants. Growers normally select hermaphrodite plants in the field, due to market preferences. This requires planting multiple plants per site and later thinning of the females, distinguished by flower bud inspection. Micropropagation or the use of molecular markers are two possibili

7. Alternative method of sowing canola hybrids using adhesive tape
ABSTRACT Canola, which has tiny oil-producing seeds, requires care during planting, so that there is an ideal number of plants. The aim of this study is to evaluate alternative method of sowing using adhesive tape and the influence it has on the emergence and vigor of the seedlings of different canola hybrids and define the best positioning of the adhesive t

8. Effect of canopy cover on development of cedar (Cedrela fissilis) and aspects of damage caused by Hypsipyla grandella in agroforestry system
Resumo Cedrela fissilis (Vell.) é uma importante espécie madeirável nativa da América do Sul que sofre frequente pressão do extrativismo ilegal. As iniciativas de cultivo comercial acumulam fracassos recorrentes pela ação da broca-do-cedro Hypsipyla grandella (Zeller, 1848). Um dos métodos de manejo utilizados para reduzir os ataques é o plantio em

9. Herbicide selectivity for potato crop
RESUMO Estudos sobre seletividade de herbicidas para a cultura da batata são poucos, especialmente em condições brasileiras. Por isso, objetivou-se estudar a ação fitotóxica de diferentes herbicidas para a cultura da batata, cv. Agata. Dois experimentos foram desenvolvidos em área de produção comercial, no delineamento experimental de blocos ao acas

10. Soil cadmium extraction in Chinese cabbage and cabbage intercropping
RESUMO: A contaminação do solo por metais tóxicos tornou-se um problema grave nos últimos anos. Neste estudo, dois tipos de repolhos, o repolho chinês (maior acumulador de cádmio (Cd)) e o repolho comum (menor acumulador de Cd) foram cultivados em monocultivo e em consórcio, em solo contaminado com esse metal, para avaliar o efeito do consórcio na e

11. Use of 2,4-D in Mixture with Ethephon and Calcium Carbide in Pineapple Crop
RESUMO: O ácido 2-cloroetilfosfônico (ethephon) e o carbureto de cálcio são usados para induzir e sincronizar a floração da cultura do abacaxi. Alguns produtores têm utilizado, em associação com esses indutores do florescimento, o herbicida 2,4-D. Essa prática baseia-se na hipótese de que o 2,4-D atua como regulador de crescimento, aumentando o ta

12. Herbicide selectivity in pre-sprouted seedlings of ‘CTC14’ sugarcane
RESUMO: Um novo sistema de plantio de cana-de-açúcar, utilizando mudas pré-brotadas (MPB) em substituição aos fragmentos de colmos de cana, fundamenta a hipótese deste trabalho de que poderá haver intoxicação nas mudas pelos herbicidas aplicados na pré-emergência em sistemas tradicionais. Portanto, objetivou-se neste estudo verificar a seletividad
