Mineral nutrition of Cyclanthera pedata

Abstract

The objective of this work was to characterize the nutritional limitations for dry matter production of Cyclanthera pedata (L.) Schrad. Two successive cultivations were conducted in 3 dm³ pots with soil. The experimental design was totally randomized with 13 treatments and three replications. Treatments were based on the missing element technique (with omission of liming and each one of the macro and micronutrients). Cyclanthera pedata plants have their dry matter production reduced by soil acidity and low macronutrients availability, mainly P, Ca, Mg and S, and were little affected by low micronutrients availability.
