Mineral nutrition of vegetable crops: LII - growth of cucumber (Cucumis sativus L.) var. Aodai under field conditions

Abstract

A commercial cucumber plantation was set in Piracicaba (SL: 22º43'31'' and LW: 47º38'01" 0) State of São Paulo, Brazil, in a soil classified as "Terra Roxa Estruturada (Alfissol), série Luiz de Queiroz". Plants (4 replications) with 12, 24, 36, 48, 60, 72, and 84 days from emergence were collected and divided into stems, stem leaves, shoot leaves, masculine and feminine flowers, and fruits. The material was dried at 80ºC to determine the dry matter weight. The results were as folows: - the growth rate is continuous, increasing the dry matter produced by the branches, leaves and fruits; at the 84th day from emergence the production of dry matter, in grams, was 63.4 for the stems and reamifications (25-7%); 88.4 for the leaves (41.4%); 61.5 for the fruits (28.8%); the plant total weight was 213.28 g.
