Abstract
ABSTRACT The need to adapt agricultural crops to climate change and to develop more sustainable cultivation systems has been a major challenge for agriculture. In this study the effects of soil conservation practices were evaluated on production aspects of melon (Cucumis melo), cultivar BRS Araguaia, cultivated in a greenhouse under soil and climatic conditions of the Brazilian Cerrado. The adopted experimental design was of randomized blocks with three treatments (soil managements) and six replicates. We evaluated the following soil management systems: no-tillage (PD), minimum tillage (CM) and conventional tillage (PC) in two cycles. Increases in commercial productivity and average number of marketable fruits were observed for PD (61.5 and 61.2 t/ha; 56,000 and 44,300 fruits/ha in the first and second cycles, respectively) and CM (59.7 and 57.5 t/ha; 55,700 and 42,400 fruits/ha in the first and second cycles, respectively). No effects of management systems on fruit quality were observed. PD and CM were effective in increasing the melon production under evaluated conditions.
Highlights
A necessidade de adaptação de cultivos agrícolas às mudanças climáticas, aliada à necessidade de desenvolvimento de cultivos mais sustentáveis constitui um grande desafio para a agricultura
The cultivar BRS Araguaia, a “yellow” melon hybrid (Cucumis melo), developed at Embrapa and Emater was used in the assay
The intermediate productivity was for cultivo mínimo (CM) (59.71 t/ha)
Summary
A necessidade de adaptação de cultivos agrícolas às mudanças climáticas, aliada à necessidade de desenvolvimento de cultivos mais sustentáveis constitui um grande desafio para a agricultura. In Brazil, Hamada et al (2012) reported a strong trend towards an increase in average air temperature for all the Brazilian regions, with major climatic anomalies that are expected for the Central-West region. This fact highlights a possible need, in the Central West region, of agricultural practice management adapted to such temperature conditions, favoring species adapted to warm conditions. This research aimed to evaluate the productivity and postharvest characteristics of melon, cultivar BRS Araguaia, grown in a greenhouse under three different soil management systems: no tillage (PD), minimum tillage (CM) and conventional tillage (PC) under soil and climatic conditions of the Brazilian Cerrado and two distinct periods of the year
