Eficiência no uso da água e interferência de plantas daninhas no meloeiro cultivado nos sistemas de plantio direto e convencional

Abstract: RESUMO -Com o objetivo de avaliar o efeito dos sistemas de plantio direto e convencional e estratégias de manejo de plantas daninhas na economia de água de irrigação na cultura do melão (Cucumis melo), conduziu-se um experimento na horta didática do Departamento de Ciências Vegetais da Universidade Federal Rural do Semiárido, em Mossoró-RN, utilizando o delineamento experimental de blocos casualizados, no esquema de parcelas subdivididas. Nas parcelas foram avaliados dois sistemas de plantio (plantio direto e … Show more

“…O plantio direto beneficia também o desempenho das culturas, melhorando a eficiência no uso da água, em consequência do aumento na infiltração e da redução de perdas por evaporação (Teófilo et al, 2012). Além disso, a perturbação mínima do solo, apenas na linha de plantio, associada à cobertura deste com palhada reduz a taxa de germinação e emergência de plantas daninhas, reduzindo ou até mesmo evitando a realização de capinas ou uso de herbicidas (Silva et al, 2009;Nascimento et al, 2011;Teófilo et al, 2012).…”

“…Several studies have recently been developed to promote the rational use of water in agriculture (MAROUELLI et al, 2010;SOUZAet al, 2011;TEÓFILO et al, 2012). The association of the use of efficient irrigation methods, such as drip irrigation employing a suitable volume of water, has been shown to increase the efficiency of water usage, providing suitable conditions for optimum plant development and higher productivity (TEÓFILO et al, 2012;VIANA et al, 2007).However, beyond the effective control of the volume applied in irrigation, the adoption of mechanisms that may promote greater efficiency in water usage is fundamental to raising the water-retention capacity of the soil by increasing infiltration and reducing evaporation and surface runoff.…”

The reduction of water loss through evaporation can be achieved by such strategies as mulching with inorganic material, such as polyethylene film, or with organic material of vegetable origin (TEÓFILO et al, 2012). A ground cover of plant material (straw) is one of the principles on which the no-tillage system is based, as well as not turning the soil and of crop rotation.…”
